How to build a chimney from brick

One essential component of making sure your home has effective heating and ventilation is building a brick chimney. A well-built chimney is essential for both functionality and safety, and it also improves the visual appeal of your home. Knowing the foundations of brick chimney construction is crucial, whether you’re building a new chimney or remodeling an old one.

First and foremost, it’s crucial to become familiar with local building codes and regulations before beginning the construction process. In order to maintain compliance with safety regulations, building codes frequently specify the chimney’s dimensions, composition, and location. In this regard, seeking advice from professional contractors or local authorities can be very helpful in preventing future problems.

Any structure’s foundation acts as its skeleton, and chimneys are no different. Laying a sturdy foundation is essential for maintaining stability and supporting the weight when building a brick chimney. Usually, steel rods are used to reinforce the concrete used to build the foundation, giving it more strength. The size and height of the chimney are just one of the many variables that will affect the foundation’s measurements.

The chimney base, or footing, must be built after the foundation is in place. The foundation for the remainder of the chimney is created here by laying the initial few layers of bricks. To offer stability and equally distribute the weight, the base of the chimney is usually wider than the remainder of it. The base needs to be carefully checked to make sure it is level and aligned correctly.

Dismantling a brick chimney

Not only do old brick buildings not function well, but they can occasionally endanger human life. These chimneys ought to be demolished because they are typically not profitable.

A brick chimney is easy to disassemble; just take each component apart, brick by brick. The section on the roof is always the first to be disassembled. Its gradual progression to the furnace is the fundamental working principle. This section of the chimney needs to be disassembled carefully because cement is constantly added to the mortar to ensure that bricks on the outside adhere to one another reliably. Chimneys with brick plaster are even more difficult to disassemble.

After the outer chimney has been disassembled, the part that is in the building’s attic needs to be disassembled.

Kindly take note! Covering the resulting hole in the roof is imperative before you begin dismantling the brick chimney in the attic. For example, a metal tile that was left over after the roof was installed or an iron sheet would work well for this.

The chimney needs to have specific grooves installed in order to prevent plaster from the ceiling from collapsing unintentionally. A hammer or any other makeshift tool can be used to break the sand and clay mortar with ease.

Dismantling the old chimney should begin at the exterior of the chimney.

What are the chimneys

Depending on what is made of the furnace chimney’s root or nozzle inside the house.

  • Root chimneys are made separately from the stove itself and then connected to the stove by means of a spigot. Root chimney is very well suited for brick or cast iron heating, and several stoves can be connected to one such chimney at the same time. In this type of connection, the chimney must be of a certain size, according to the standards.
    If you make such a chimney for a gas cast-iron stove or gas boiler, it is better to insert inside the metal pipe. To install the root chimney must make a separate foundation, with its depth should be at least 30 centimeters, and the perimeter should be made larger than the structure itself by 15 centimeters.
  • The extension chimney is a complete continuation of the stove structure. Such a pipe is made if it is necessary to get rid of combustion waste from only one stove.

Solid fuel for chimneys The boiler has more internal channels and is therefore more complex. In addition, the chimney serves as a fireplace, boiler, furnace, barbecue, and bath house.

What the chimney consists of?

The same principles apply to the installation of both types of chimneys; the only exception is that multiple stoves may require the arrangement of multiple risers and sections, the number of which directly relates to the number of floors in the home. The scheme-drawing shows the major components of the chimney.

  1. Smoke gate valve;
  2. Insulation;
  3. Beam with overlap;
  4. Rasvushka;
  5. Chimney riser;
  6. Rafters;
  7. Roof;
  8. Otter;
  9. Purlins;
  10. Cement mortar;
  11. Chimney Neck;
  12. Pipe header;
  13. Metal cap.

The part that runs from the stove to the partitioning is called the chimney neck. It’s used to create a smoke damper, which helps further control the draught. The combustion or smoldering force must be controlled by the draught itself.

Raspushka should be placed along the pipe’s path, accounting for each floor; this shields the floors from the damaging effects of high temperatures. Its walls are extremely thick; ideally, they should be between 35 and 40 centimeters thick. This allows for up to 25 centimeters of insulation to be added to the perimeter.

A chimney riser is a pillar made of brick with a chimney duct in the center. It is installed in the attic floor and before the chimney is divided.

The chimney itself ought to rise straight above the otter’s head. The chimney header is shaped like an otter with a pad, a neck, and a unique projecting cap.

Upon cap Attaching a cap or umbrella from the top is required to keep out dirt and precipitation. This device also aids in generating a good draft in the channel.

Chimney masonry

The masonry masses of chimneys and stoves are not fundamentally different from one another. Using the same stove hammer, trowel, and building plumb line, it is done on clay-sand mortar. However, a lot of brick pieces in the sizes of 1/8, 1/4, 1/2, and 3/4 of a whole brick are used to arrange elements like raspushka and otter.

To prevent brick dust clouds and unsatisfactory results from pounding and hewing, it is worthwhile to use a "bolgarka" with a diamond wheel when working with ceramics. This eliminates labor-intensive work and a ton of pointless brickwork while guaranteeing accuracy of the job.


A sand and clay mixture is used for masonry up to the roof level because it has a coefficient of linear expansion that is comparable to brick, providing a certain guarantee against cracks.

Either fat or lean pure clay can be utilized as a binder. There are deposits in some locations where the proportion of sand to clay is ideal by nature—one to three or four.

After drying, the mortar will fracture if the volume fraction of clay is raised, and it will crumble if it is lowered. The parts should be prepared with mortar that has been kneaded with the fingers in order to assess the ideal volume ratio. It shouldn’t feel noticeably slick or scratchy like sandpaper.

For three to four days, the extracted clay is submerged in an iron container. The end product ought to be a smooth, stone-free clay pulp that resembles liquid sour cream in consistency.

Fine, dusty sand extracted from the floodplain of rivers and streams. This isn’t appropriate for masonry. Use the one with the grains measuring between 0.81 and 1.01 mm. To the touch, it feels rough.

In volumetric portions, clay and sand are combined in a ratio of one to three or four. Water is added little by little and gradually. The ready mortar should run off the trowel and leave traces on it, but not stick to it.

It is preferable to purchase a ready-made dry clay-sand masonry mixture to prevent proportion errors.

Note that the item tagged as "fireproof" is not appropriate for masonry.


Red-colored, fully-burned bricks are utilized.

Its edges ought to be smooth, free of cracks, and should make a ringing sound when lightly struck with a stove hammer.

The typical dimensions for masonry are 250 mm in length, 125 mm in width, and 75 mm in height.

Internal chimney masonry

As soon as the damper is mounted and the stove’s overlap is finished, it is turned on. The methods for laying bricks, applying a layer of mortar, "shaking" them by hand, and gently tapping them with a pick are all the same. After each row is laid, it is important to check for verticality and horizontality. The ceiling slab is reached after four brick heights of completion.

Laying the flue

In order to maintain the necessary 250 mm "from the smoke" distance between combustible structures, the thickness of the chimney wall is extended. The typical thickness of the chimney’s walls is 125 mm. To double it, stack four rows, each spaced 1/8 the width of the brick from the bottom row; this is the ideal amount to allow the brick to lay without toppling over. For all three sizes, the masonry principle is the same:

  1. The inner surface (to the smoke) of the first row is laid out in parts of 1/8. The gaps between the outer bricks are filled with pieces of 1/4.
  2. In the second row, the parts are increased, respectively, to 1/4 and 1/2.
  3. On the third row 1/2 and 3/4 pieces are used.
  4. The outer belt of the fourth row of the otter is laid with whole bricks.

After reaching the ceiling, it is placed two or three more rows higher while keeping an eye on the joint dressing. A space of two to three centimeters is left between the ceiling and the masonry to prevent structural pressure. Boards made of mineral wool close it. The customary method of tying vertical joints and controlling verticality is used to complete the masonry up to the roof.

Otter masonry

It is initiated subsequent to the chimney brick’s edge rising above the roof. It is completed from the outside while adhering to all safety precautions for working at a height. Use cement mortar if desired. Since the edge is lower on the slope, start it there. Each row’s indentation from the smoke is one-eighth the brick’s width. The otter should have six rows in total. Following it was the neck, which is the customary chimney continuation. Steel sheet roofing is used to create a "collar" to seal the spaces between the roof and the chimney.

Laying the casing

This device, a chimney deflector, prevents smoke from getting stuck in the chimney when air swirls.

It is arranged in two rows, one on 1/2 brick and the other away from the smoke on 1/8 brick.

The metal cap has protrusions where you can hook the clamps to keep snow out of the chimney.

Repair of a brick chimney pipe from a gas boiler

  • Failure detected during regular inspection of the brickwork.
  • Conversion of the chimney system to allow the use of conventional brick chimneys for modern gas boilers.

Why the brick on the gas chimney is destroyed?

  • Exposure to condensation – poorly insulated masonry of the attached chimney on the outside of the house is the cause of condensation. Under the influence of temperature differences and soot accumulation, a strong acid is formed, destroying the mortar joint and brick. The same problem is encountered when laying internal brick chimneys, especially if not insulated section passing through the attic room.
  • Negative environmental impact – bricks have thermal load limits. Improper choice of material for masonry, leads to the destruction of the walls, after 1-2 heating seasons. Overheating affects the strength of the facing brick. Permissible surface heating rate of no more than 50°C.
  • Destruction of the foundation – recommendations for the construction of exterior wall brick chimneys outside the house, prescribe the manufacture of a base reinforced with metal bars, 1 cm thick. The width of the foundation exceeds the masonry by 15 cm on each side of the channel. Erection of the structure is carried out only after the foundation is fully hardened, a month after pouring.

Whether a brick chimney needs to be sleeved and with what?

  1. Increased condensate formation.
  2. Location of chimney pipes from gas boilers in a brick ventilation shaft.
  3. Destruction of a brick chimney.

How to clean a brick chimney with gas heating

Advantages and disadvantages of connecting a gas boiler to a brick chimney

  1. Low cost if you can use an existing chimney.
  2. Possibility of connecting a gas boiler with an open combustion chamber to a brick chimney.
  3. Availability of construction and finishing materials.
  1. Short service life.
  2. High requirements to the quality of masonry and qualification of the worker carrying out construction works.
  3. The need for insulation.
  4. Many restrictions – to make a gas chimney in an exterior brick wall, to use the old channel without sleeving, to connect the system to condensing boilers and equipment with a closed furnace chamber is prohibited.

Laying the chimney


The first thing you should do is become thoroughly acquainted with the chimney’s design and learn how to lay each row. There are numerous schemes to choose from; it is best to select the one where everything is crystal clear. A typical brick chimney is appropriate for installing an ordinary brick stove.

Among the most popular designs for chimneys

Erection of an overhead chimney

The direct erection of the chimney channel commences when the overhead pipe installation is completed, with the stove structure’s masonry ending 50 to 60 centimeters before the ceiling. The square and rectangular shapes of masonry chimneys are depicted in this scheme.

  • According to the scheme of the first row the neck of the chimney is erected up to the partitioning. In each subsequent row, the bricks are laid in such a way that the middle of the brick overlapped the seam between the bricks of the previous row.

You begin laying out the chimney’s flue after completing three or four rows in accordance with the first row’s layout.

This is the external appearance of the swelling.

  • In the picture of the second row you can clearly see that the bricks are laid with a shift to the outside by one third of a brick. To perfectly fit the piece material, it will be necessary to use the division of the whole brick into two or three parts along or across .

And this is how it’s set up.

Throughout all of this, it’s important to keep in mind that the chimney channel should maintain its original cross-section because the purpose of thickening its walls is to make the slab safer to operate in. particularly because the draught during firing may be adversely affected by the inner cavity’s narrowing or widening.

  • The third, fourth and fifth rows are also laid out with a shift to the outside, maintaining the channel lumen.
  • The sixth row has the same size as the fifth row and is laid flush with the outer and inner edge of the chimney wall.
  • The seventh and eighth rows are laid out according to the scheme of the first row.

Once the fluff layer is complete, you can work on the otter, but this will require a lot of effort because each row forms a step and extends one third of the way to the outside.

  • The first row is laid in the same size as the last row of the flue.
  • From the second row begin to lay out the first step, and there is an expansion of the chimney to the outer side.
  • Then, following the scheme, lay out the remaining eight rows.

Following the completion of the otter’s masonry, the pipe’s neck is laid out. This is done in accordance with the first row’s layout scheme and continues to the top two rows of the cap, where brick is also laid with an outer side projection.

Chimney stack design and principle of operation

The traditional chimney design consists of a vertical tower with a through hole inside to link the furnace firebox to the outside area of the home. Physics states that as air travels away from the surface of the earth, its pressure drops. Consequently, there is an internal draught within the pipe, which is the result of the air mass’s propensity to rise to the top. When the airflow from below is stopped, the draft goes away. This is why installing a ventilator or flue damper in the chimney, which can be used to control the draught, is required.

A damper can be used to control the draught and the size of the smoke channel.

Since residential buildings use chimneys, it must not present a fire hazard. For this reason, the masonry is laid with the highest level of fire protection. There is a specific vocabulary among stovemakers that describes the composition and function of the pipe’s component parts.

  1. Overhead chimney. Placed directly on the stove, connected to the furnace chamber. Usually does not reach the horizontal floor by 5-6 brick rows (35-40 cm). The gate valve is located in this part.
  2. Fluffing (or cutting). Thickening of the outer casing inside the slab. The purpose is to prevent thermal contact of the floor material and cross beams with the chimney. In this place the temperature of bricks reaches maximum values, so it is important to take all measures to ensure safety. The internal dimensions of the chimney remain unchanged.
  3. riser. The part of the pipe from the flue to the roof. The size of the riser is usually the same as the size of the extension chimney. The size of the internal cross-section is preserved. If the attic space is equipped as a living space, the riser performs the function of a heater.
  4. Otter. Thickening of the outer dimensions of the chimney in order to cover the opening in the roof from possible precipitation. A minimum overlap of 10 cm around the entire perimeter of the pipe is considered to be the minimum. The height of the otter depends on the slope of the roof. The upper part of the pipe ends with a drainage scum made of cement mortar of high moisture resistance.
  5. Pipe neck. A part of the chimney made by laying brick on waterproof mortar. Located above the otter, it has the same geometric parameters as the riser.
  6. Pipe header. Expansion of brickwork at the end of the chimney. It has protective functions, it prevents foreign objects from getting inside the pipe. It is often reinforced with a metal frame, deflector or weathervane. All brick chimneys are made according to the same scheme, consisting of several standard elements

A combined chimney design is used in certain situations. The attic is where the brickwork ends, and from there a metal or asbestos pipe is mounted and runs to the roof. This saves a great deal of time and money because an otter, neck, and header are not required. It is important to keep in mind that the cross-sectional area of the brick chimney and the metal chimney should not differ by much. The arrangement of an asbestos pipe inside a stainless steel pipe has shown to be effective.

You can convert a brick chimney to a metal one in the upper portion of the chimney, where the flue gas temperature is lower.

It is necessary to cover the upper opening in both situations with an umbrella or deflector to keep snow and rain from going straight into the chimney.

Compliance with the main requirements

Designing or constructing a brick chimney by hand and permitting a breach of established conventions is a foolish move that could lead to unfavorable outcomes. It is necessary to keep an eye on their compliance at every stage of the project.

Initially, the installation of the compensating supply system and the exhaust ventilation system need to happen simultaneously.

Secondly, the smoke cannot be released through the ventilation grilles’ channels. Any impediment that appears in its path should not be permitted to trap it, as this will undoubtedly lead to accumulation.

Once you’ve made the decision to purchase a fireplace, keep in mind that it will require an interior partition constructed of fire-safe materials. External insulation is installed if needed to prevent condensation of the gases discharged from the chimney or to greatly reduce its amount.

In the event that installing chimney channels in the walls is not feasible, appropriate attachments (placed directly on the furnace slab) or root (separated brick risers) pipes should be used.

It is important to keep in mind that only one fireplace may be connected to a different chimney. When two fireplaces are situated on the same floor and linked to a single pipe, there might be an exception, though (keeping in mind the dissection requirements: thickness of 12 cm and height of 1 m from the bottom connection).

Sensible owners frequently use radiator pipe to extend the fireplace’s heating area. The controlled air exchange will manage the combustion intensity while the hearth is running. As an alternative, a damper is put in.

The simplest way to organize smoke extraction is to build a vertical smoke extraction system that is higher than 7 meters, or you can use a more intricate design with extraction angles greater than 45 degrees. Don’t overlook the necessity of a tee when using the elbow; it can make cleaning easier.

The chimney’s location and thermal protection system need special consideration. The building will be extremely hot due to the volatile products of combustion, so it’s critical to safeguard the walls and floors from potential fire.

It will be necessary to insulate the chimney, preferably with basalt wool, if it is to be located near wooden or plastic structures.

The area where the channel goes through needs to be further insulated, and a fungus or vane should be placed atop the pipe.

Waterproofing of the roof penetration unit

The last phase of construction is to protect the chimney’s passageway through the roof.

This is the most important point because the quality of the waterproofing determines how long the chimney will last. The assembly of the passage through the roof is consistently shielded from precipitation and condensation by the outer apron. Using mastic or sealant alone to close the space between the stove pipe and the roof is insufficient.

The sealant layer eventually separates from the riser, fractures, and stops working. Reliable moisture protection requires a number of requirements to be satisfied.

Merely using mastic or sealant to seal the space between the stove pipe and the roof is insufficient. The sealant layer eventually separates from the riser, cracks, and stops working. Reliable protection against moisture requires the fulfillment of several requirements.

  1. The place where the chimney exits to the outside is located as close to the ridge as possible to minimize the formation of snow caps in the winter time.
  2. When installing the roof covering, the place of the junction with the riser is equipped with a moisture drainage system, moisture-resistant membrane and protective apron.
  3. In the place where the apron is attached to the chimney, a 1-2 cm deep groove is made. It is enough to prevent precipitation and condensation from entering the joints.
  4. A sealant resistant to constant temperature changes is used for waterproofing.

The construction can be covered with another cover if desired, which will improve its aesthetics.

It is incorrect to believe that the brick chimney is a 20th-century invention. On the other hand, the most cutting-edge stove pipes are made of two parts: an inner steel sleeve and an outer brick casing. These pipes have an extended service life and can increase the furnace’s thermal efficiency by a number of degrees. As you could see, building a brick chimney does not call for any specialized knowledge and is easily accomplished by someone who is accustomed to doing tasks by hand. So go ahead and calculate and confidently get to work!

Brick chimney construction

The size of the chimney channel’s cross-section directly affects the stove’s power:

  1. For small stoves, a square cross-section with a rib of 120-150 mm will be enough. Most often it is a channel that has a row of four bricks, so often the size of such a section is called a quarter;
  2. A bathhouse of 15-20 cubes or a fireplace will require a chimney with a cross-section size of "five" or 125×250 mm. When laying in a row, five bricks are placed in the row;
  3. For Russian stoves and large sauna stoves use the "sixth" size with a channel of 250×250 mm. This is a very large cross-section, and it should be used only for low-seated pipes or a very large furnace furnace.

The chimney’s masonry is structurally identical to that of the stove; the overhead pipe is the only part that needs professional hands and expertise. This is the point where the laid brick needs to be properly dressed. As shown in the figure, the pipe for a basic tower chimney design can be made of alloy metal and connected to the brick main channel.

How tall should a chimney be built? Regarding the installation and arrangement of the chimney’s height from the brick and the house’s roof ridge, there are some guidelines. Anything further away shouldn’t be 0.2–0.3 meters below the ridge.If the pipe is situated up to 1.5 meters from the ridge, it is raised to a height of up to half a meter above the highest point of the roof. At a distance of up to 3 meters, the pipe cut can go to a level with the roof’s ridge.

When the chimney’s overall height is raised to five meters, it becomes possible to supply 1-2 m 3 of "on cold" air intake per hour, which is more than sufficient to light the stove. The stove will not be cost-effective with taller chimneys.

Traditionally, a brick masonry chimney is separated into two sections: the portion up to the raspushka, or widening, and the portion above it. The raspushka is a brick thickening or strapping system that enables the fixing of a highly unstable high structure in the home’s ceiling system. Except for the potential to fasten it to the ceiling joists, the flue should not be disregarded despite its blatant inefficiency. This component stabilizes the comparatively thin brick chimney and stops lateral wind loading-related cracks from forming.

The chimney pipe has an otter and a header in addition to the flue. A belt or thickening at the top of the chimney pipe above the roof is the first component. It functions as an umbrella over the intersection of the roof and the brickwork and cannot be made. Brick or steel can be used to create the header. Since neither component affects how the furnace operates, a decorative casing and a cap can be used in simpler designs to prevent snow and water from penetrating the cut.

Favor straightforward and dependable vertical chimneys when selecting a chimney design. They don’t need to be maintained frequently and are unassuming.

This option should last you many years if you select the proper bricks and mortar for the masonry and maintain the vertical above the stove. In the event that the stove’s design changes, adjusting and modifying such a chimney is fairly simple.

Rules for laying a brick chimney

It’s advised that you become familiar with the laws and guidelines pertaining to brick stove pipe installation before beginning the task yourself. The stove unit’s stenciled drawings and the building’s fire safety components must be included in the design document.

It is best to use full-body ceramic stove brick—a brick without chips or cracks—for stoves and fireplaces that are used in heating boilers with flue gas temperatures ranging from 140 to 300 degrees Celsius. Bricks that are silicate can only be used for the chimney head.

Up to four storey buildings use brick masonry chimneys.

The chimney’s lowest point is five meters, with a cross section that allows the smoke outlet to be as small as 14 by 14 cm. Because hot, sparking gases escape through the chimney, extra caution must be taken when filling the mortar joints to prevent fires.

An umbrella for precipitation protection and a spark arrestor are required at the structure’s mouth.

Chimneys with a circular or quadrangular cross-section can be constructed using brickwork. Round pipes have the advantage of having a higher exit velocity of cooled combustion products and less internal soot deposition. However, the process of erecting square section masonry requires less money and labor.

To keep air-hardening mortar from setting, it must be constantly stirred. The masonry is created in a minimum temperature of 10 °C. Every horizontal and vertical joint is entirely filled with mortar. Masonry chimney joints should have a maximum thickness of 10 mm.

It is not acceptable for the structure to unfold and twist in relation to its axis while it is being built. A rule is used to verify that the masonry is straight.

Soot is removed from chimneys every two months after the start of the heating season.

During the cold season, the air temperature is taken into account when calculating the distance between the smoke and the wall’s exterior:

  • at t ° – 30 °C is 60 cm;
  • at t ° – 2 0-30 °C is 51 cm;
  • at t ° – 20 °C and above should be 38 cm.

To avoid the smoke and condensate formation from supercooling, these parameters must be followed.

How to calculate the cross-section of a brick pipe

Air is moved from the furnace section to the exterior outlet by a brick chimney. A draft is produced by the chimney and is caused by a difference in pressure and temperature. The power of the heating element and the furnace component should be taken into account when calculating the cross-sectional area. In order to prevent soot buildup and obstructions to air flow, the chimney needs to be smooth. Occasionally, the chimney is constructed with a smooth tin pipe for this reason.

The internal diameter is determined by the boiler’s (stove’s) power and the chimney’s overall length. The number of channels within the stove also affects normal operation. The stove (boiler) will cool down or have less draught when the power is low if the pipe is too long and the chimney’s cross-section is too large. Which pipes offer the best draft is a frequently asked question. Whether the pipes are made of brick or steel has no bearing on the draught.

The chimney cross-section to the area of the stoking window measures one to ten in the case of a fireplace with an open stoking window. This holds true for all pipe forms.

The cross-sectional ratio in a stove with a closed system will be 1 to 1.5.

Plan for figuring out the opening:

Height in meters 5 6 7 8 9 10 11
Pipe cross-section Ratio of cross-section to area of stoking window in %
Circle 11,2 10,2 10 9,5 9,1 8,7 8,9
Square 12,4 11,6 11 10,5 10,1 9,7 9,4
Rectangle 13,2 12,3 11,7 11,2 10,6 10,2 9,8

For instance, the overall area will be 0.42 square meters if the firebox window is 600 by 700 mm in size. 11.6 percent is ideal for a square cross-section chimney with a chimney height of six meters. Now, multiplying 0.42 by 0.116 yields a square of 0.0787 meters. Considering the pipe’s height necessitates considering its cross-section. A two-meter-tall, seven-meter pipe in a restroom will not be visually appealing.

Small tips of a big deal

Inexperienced builders mistakenly think that building walls and laying a brick chimney are the same thing. Nonetheless, the stove pipe’s construction has unique subtleties. In particular, experts do not recommend the use of cement-sand mortar. Such mortar cannot endure the abrupt temperature changes that take place in the chimney pipe’s wall. Furthermore, condensation that eventually collects on the pipe wall will deteriorate regular mortar.

As a result, installing a brick chimney requires the use of mortar that is both chemically and thermally resistant. It is possible to use premade mixtures to prepare the mortar. Specifically, experts advise against using mortar made of cement and sand. A few experts advise utilizing mortar made of clay.

If the boiler is gas

If the brick chimney device makes sense for a wood stove or solid fuel boiler, it is not the best choice for eliminating smoke from a gas boiler. It all comes down to how the gas boiler, solid fuel furnace, and furnace operate in their various modes. The efficiency of the heating unit will be reduced if a rectangular brick pipe is used with a gas boiler and the solid fuel equipment does not require a large draught.

The requirements for the chimney device vary depending on whether a gas boiler is being used or solid fuel equipment is being installed. Thus, in the event that a house is being built, a metal pipe chimney must be installed in order to use a gas boiler.

It is not necessary to build a new chimney if a gas boiler is installed in place of a wood or solid fuel stove. On the other hand, the gas boiler flue requirements need to be fulfilled. The brick chimney in this instance has been sleeved, or a metal pipe has been installed inside the pre-existing brick chimney. The old chimney won’t need to be disassembled in this way, and the chimney arrangement requirements will be satisfied.

Nothing is impossible

By and large, brick chimneys with their own hands – quite a feasible task for any person who likes to work with his hands for his own pleasure. Sometimes it is believed that brick chimneys are a thing of the past. This is not true, for example, gilzovka brick chimney pipes with a special coating, and the device brick chimney allows you to do this, allows you to use them in the work with the most modern heating boilers. We hope that after reading this article you have dropped the question of how to properly make with your own hands brick chimney for a fireplace or stove. Try, practice, and brick chimneys built by your hands will please you and your loved ones with perfect work under any conditions. Good luck!

Facing the stove and the trunk of the chimney with ceramic tiles

New stoves typically have gorgeous looks. On the other hand, some people would rather tile it. In addition to being elegant, this will prolong its useful life—particularly in the bathhouse, where the air humidity is high. How can one lay tiles by hand? You can handle it if you know how to lay bricks for a chimney. Selecting the appropriate tile adhesive and tiling material is crucial.

How should tiles be laid to prevent peeling? Regular ceramic tiles have a high likelihood of peeling or cracking when used for tiling. The best materials will be porcelain stoneware, terracotta, and clinker.

More robust is terracotta. Pressing creates it.

Porcelain and clinker tiles are thicker, more fire resistant, and highly resistant to impacts.

The chimney’s surface is moisturized and completely free of dirt. A metal grid is stretched on top with the assistance of dowels. The mesh enhances the plaster’s adherence to the brickwork.

Plated using a cement and clay mortar. three parts cement to one part clay plus two parts sand. Heat is applied to the stove after plastering. You can then adhere tiles.

Beacons and crosses are used to level the rows before tiles are adhered to heat-resistant glue. Use the same glue to grout the joints.

You can avoid hiring experts if you put in the necessary time and effort to handle the chimney’s erection yourself.

What you need to know about the brick chimney

It goes without saying that people today aspire to all the conveniences of civilization, so it is unlikely that anyone will intentionally build a stove with a chimney in the cottage.

However, dacha houses here are incomplete without this crucial element, particularly if you intend to visit frequently during the winter. By the way, a chimney is also necessary if you intend to build a fireplace.

Bricklaying chimneys can be expensive; experts who construct stoves and fireplaces using the antiquated, "grandfather" techniques charge a premium for their services, claiming to have the "secret method." In actuality, building masonry chimneys by hand is not so "mysterious"; all you need to do is focus on each step of the building process, and you will succeed!

The chimney is made up of multiple parts, so anyone who believes it is just a regular pipe is greatly mistaken. Experts state that although the draught was strong, it should not be weaker if the chimney is lower than five meters in height.

Study every component of the chimney pipe thoroughly before you begin laying it; only then will you be able to comprehend every step of the building process.

What makes up a brick chimney is as follows:

  1. The beginning of the chimney – the extension pipe. It is installed directly on top of the stove (fireplace). Most often it is here that the gate valve is located. Lay out this part of the chimney must be in compliance with the mandatory dressing of bricks in each row. The nozzle part is about five or six rows of bricks. Nozzle part should not reach the interfloor ceiling, so its height depends on the height of the ceilings and the stove, as well as the interfloor ceiling.
  2. The neck of the raspushka or simply raspushka – follows the nozzle pipe. This is exactly the place where the pipe expands slightly. It is worth noting that the chimney itself remains the same size as it was, and the expansion appears thanks to the brickwork. The outer part of the chimney extends from about 25 centimeters to 40 centimeters – thanks to the laying of bricks in several rows.
  3. After the flue is the riser – this is the part of the chimney that starts in the attic and reaches the roof.
  4. Otter is a part of the chimney that expands again on all sides by at least 10 centimeters. Thanks to this expansion, atmospheric precipitation will not enter the attic through the cracks. Otter protects the supporting structures, roofing, flooring and items you will store in the attic, as it will not allow moisture to get in.
  5. Chimney neck – after the otter there is a flat part of the chimney, which resembles a riser by its masonry.
  6. Header – the final part of the chimney. The masonry is expanded again. On top of the most often put a metal cap, weathervane or deflector – thanks to this you can secure the chimney from precipitation, and also noticeably increase the draught.

Choice of tools and material

You will require the following tools in order to build a chimney:

  1. Level.
  2. Measuring tape.
  3. Hammer with a rubber tip.
  4. Hammer for bricks.
  5. Trowel.
  6. Chimney sweep.
  7. Buckets – some for water and some for mortar.
  8. Electric drill + mixer attachment.
  9. A container for diluting the mortar.
  10. Sieve.
  11. Brick.
  12. Sand.
  13. Clay.

Choosing a brick

The selection of brick to be used in the construction of the chimney is a crucial decision regarding fire safety. Bricks come in a plethora of varieties nowadays, each with its own unique look, shape, and color. Bricks are fired, as you are aware, and then made usable. The three types of brick are formed by the firing stage:

  1. A well-fired brick has a red color. It has smooth walls and edges, if you knock on it, you will hear a characteristic "metallic" sound.
  2. Unburnt bricks are pink in color. If you knock on it, it makes a muffled sound. It is most often used for masonry of less important areas.
  3. Unburnt bricks are dark brown in color. It is mainly used for laying foundations.

Any of these brick kinds will work at some point during the chimney building process; just make sure they are fireproof and full-body.

In the realm of heating and insulating your home effectively, constructing a brick chimney stands out as a vital component. A well-built chimney not only enhances the aesthetic appeal of your house but also ensures efficient ventilation and proper discharge of smoke from your fireplace or stove. Building a brick chimney requires careful planning, precise execution, and adherence to safety standards. From selecting the right materials to laying bricks with proper mortar, each step plays a crucial role in the durability and functionality of your chimney. Additionally, incorporating proper insulation techniques ensures optimal heat retention and prevents energy loss, contributing to a more comfortable and energy-efficient home environment. By following expert guidelines and investing time and effort into the construction process, homeowners can create a sturdy, reliable brick chimney that serves as the cornerstone of their heating system while enhancing the overall value and comfort of their residence.

Common mistakes during installation

The primary guidelines that enable you to lay a brick chimney by hand are mentioned above.

Nonetheless, there are a few typical installation errors that you should be aware of.

The most typical errors made when putting in a brick chimney are:

One of the most frequent errors is the pipe being too short. As a result, the system doesn’t have the required draught and can’t function correctly. It is advised to calculate the height of the chimney above the roof carefully in order to avoid running into this issue.

Making improperly prepared cement mortar for masonry construction is another extremely frequent error. With time, this kind of mortar crumbles and the building is destroyed. The mortar’s fine-grained sand should have a uniform consistency.

When laying bricks, the mortar layer shouldn’t be more than 5 mm thick.

Crucial! It is crucial that the mortar be placed uniformly and not obstruct the chimney’s path, which allows combustion products to be transported. Additionally, it’s critical that the chimney be level and, to the greatest extent feasible, adhere to the SNiP standards.

Furthermore, it is crucial that the chimney was level and met all of the requirements outlined in SNiP.

Here are a few more expert tips:

Brick dressing needs to be done with extreme caution when working with masonry. During masonry, various brick parts (halves, quarters, etc.) can be utilized. д.). It is advised to use a bolt cutter to split the bricks into sections.

It is important to avoid overly thick mortar layers as they may quickly crumble and cause the structure to collapse. Four to five millimeters is the ideal layer thickness.

Furthermore, don’t overlook the importance of routine chimney cleaning. Soot, ash, and other combustion byproducts typically build up on the chimney walls. Internal channel irregularities in constructions make them particularly prone to clogging. Your chimney will be cleaned and function better with preventive cleaning.

Cleaning and repair of the chimney

Both conventional and contemporary methods—which draw on the advancements in technology—are employed to clean the chimney.

For all recorded history, chimney sweeps were the individuals responsible for maintaining stoves. It is challenging to locate a qualified chimney sweeper these days. They have been replaced with chemical products, which go by the name "Chimney Sweep" as well.

It’s very hard to find a professional chimney sweeper these days; they’re a dying profession.

As a result, the "Chimney Sweep Straw" remedy has shown to be effective. Copper sulfate salts as well as other active chemical compounds are present. These materials burn in the furnace and their vapors interact with the soot that accumulates on the pipe walls. The soot’s solid structure crumbles and burns when it is placed back in the furnace as a result of the heat-induced reaction, which lasts for several weeks. As stated by the manufacturers, you can totally clear the pipe of soot by using "miracle foam" twice a year. This causes the furnace to produce a high percentage of heat and a good draught.

The "Poleno Chimney Sweep"’smanufacturersclaim that using it twice a year will enable you to thoroughly clean the chimney of soot.

Among folk remedies, burning soda or salt once every two months (about 0.5 kg for one heating) is an effective preventative measure. When the temperature is at its highest and the wood is thoroughly heated, the powder is added to the furnace chamber. Following that, you should immediately shut all of the doors because the reaction might be quite violent.

A good wood to use for cleaning the chimney is dry aspen. The important thing to remember is that aspen burns with a high heat release, producing long, deep flames that enter the passageways.

Use potato peelings if aspen or soda are not available. You will need to gather enough potato peels for about half a bucket in order to do this. The compounds that are released when soot burns in a furnace bind it and force it to burn through.

Aspen wood burns at a temperature of 800 degrees, which causes the soot on the chimney walls to burn away.

It is essential to closely adhere to safety regulations when installing chimneys, particularly when installing neck, otter, and headband components. It is possible to assemble the brick chimney by hand if you work carefully and adhere to the required guidelines and tools.

General rules for the construction of chimneys

Certain general provisions are required for all types of brick chimneys.

Exit onto a traditional chimney’s roof

Elevation above the roof surface. Controlled with consideration for the slope angle of the slopes, it must guarantee fire safety and prevent air swirls from the ridge from blowing drafts. The fire height regulations can be disregarded if the roof covering is composed of non-combustible materials, but the chimney still needs to be protected from swirls. The image displays the suggested heights.

Requirements for fire safety

Substance used in production. For the majority of chimneys, standard red bricks will work. If purchasing fireproof is desired, be aware that it is much more expensive and that using it won’t have a significant positive impact.

Chimney construction using red brick

Since the location of the highest gas temperature is above the chimney, it is advised to only use firebrick for this purpose. The temperature of the gases in the chimney is significantly lower than that of red brick, which can tolerate temperatures as high as +800 °C with ease. Using silicate bricks is strictly prohibited because they emit harmful chemical compounds into the air when heated. These bricks are limited to finishing exterior walls.

The use of silicate brick is forbidden.

All bricks must meet a crucial requirement: their side surfaces must be smooth. Roughness and irregularities increase the amount of soot that accumulates in the chimney, requiring more frequent cleaning.

Not only can a lot of soot hinder draught, but it can also ignite, directly increasing the risk of fire. The inner channel needs to be cleared of any mortar that is sticking out of the joints as soon as the chimney is installed. To get the inner surfaces of the channel as smooth as possible, use a damp cloth or sponge.

Masonry mortar. There are two choices. While some stove workers only use clay mortar, others mix in a small amount of cement. Since cement greatly strengthens the structure, we are in favor of the second option. However, the decision is entirely yours, as both varieties of mortars function admirably.

Pre-made mortar made of clay for installing the stove

Rules of operation of brick chimneys

A capital structure with a lengthy service life is a brick chimney. For it to function properly, periodic maintenance is especially crucial. It primarily has to do with starting the chimney off correctly. It is advised to heat the stove several times with a small amount of wood in order to dry the masonry at a low temperature after the installation work is finished. This will enable the chimney’s components to dry uniformly.

In order to continue operating, it is essential to:

  1. Observe the condition of the foundation, as it may begin to deteriorate and cause the chimney to become skewed. If cracks are detected, it is necessary to carry out its restoration using a concrete-cement mixture.
  2. Inspect the chimney at least once a year.
  3. Observe the condition of the headliner, because it is simultaneously affected by high temperature of flue gases and low ambient air temperature. If the header becomes deformed or collapses, precipitation and debris will enter the chimney and gradually destroy its structure.
  4. Clean the flue duct. Frequency of cleaning depends on the regularity of use of the chimney. If it works only for one season a year, then it can be cleaned once every three years, and if the stove is stoked more often, it should be cleaned once a year.

A brick chimney can withstand up to fifty years without needing repairs if it is used in accordance with all regulations and cleaned on schedule.

How to make a chimney for a gas boiler from brick

What bricks are used to build a chimney for a gas boiler?

  • Fire resistance – the material is assigned class "A" or "B". The first is designed for heating up to 1400°C, the second 1350°C.
  • Strength – for masonry you need a brick of M 250 or M 200 grade. Greater density leads to increased heating time, so it is not recommended to use building material with a marking of M300 and above.
  • Frost resistance – the chimney is made of full-body ceramic bricks with resistance factor F300.

It is appropriate to use full-body bricks, class "A" or "B," with a strength of M 250 and a frost resistance of F300, to construct a brick chimney for a gas boiler in a private residence.

What masonry mortar is used in the construction of

  • Clay mortar – is heat-resistant, used for the construction of the structure located in the house. Clay soaks under the influence of water, so the mixture is not suitable for external parts of the chimney.
  • Cement composition – cement mortar should be used for parts of the chimney outside the building. To increase the strength and give the mortar acid-resistant characteristics, special additives are added to the ready mixture. The same mortar is used for the chimney foundation.

How to insulate a brick chimney

  • To begin with, the brick chimney must be repaired. Damaged areas are replaced. Remove the buildup from the masonry mortar, the chimney is primed.
  • To level the pipe and remove the cracks and chips, it will be necessary to plaster the brick surface. The work is carried out according to the beacons. The mortar is allowed to dry. It is forbidden to heat the chimney during this period.
  • Thermal insulation of the brick pipe is carried out – thickness of insulation 5-10 cm. Basalt insulation for exterior cladding, fixed on a special adhesive composition, after which the slabs are fixed with anchors. Reinforcing mesh is stretched on top, embedding it into the adhesive layer.
  • Finish finishing is carried out.

Arrangement of the chimney above the roof

  • When passing through slabs or roof coverings, fire clearances should be observed. In SNiP 41.01.2003 states that from an uninsulated chimney to combustible structures should be at least 38 cm. For insulated pipes, the gaps are reduced to 5 cm. The space is filled with basalt insulation material.
  • For passage make a special box, installed under the roof covering.
  • The chimney head is insulated with basalt slabs, covered with ceramic tiles or facade plaster on the top.
  • The height of the chimney is calculated depending on the distance from the ridge. There is a general recommendation that the brickwork in a private house should be above the upper roof level. In some cases, according to this instruction, it will be necessary to rebuild the existing brick chimney for the installation of a modern gas boiler.
  • The head of the chimney is covered with a deflector, to increase the draft force.

How to prevent the formation of condensation and methods of moisture removal

  • Insufficient draught – to increase the speed of air flows, increase the height of the pipe and install a deflector. The brick duct needs regular cleaning. Narrowing of the lumen is a frequent cause of inadequate draught and increased condensation.
  • Poor insulation of the system – installation of a brick chimney for a gas boiler in a wooden or brick house is carried out with mandatory thermal insulation of the structure. Often overlooked is the section that runs through an uninsulated attic space.
  • Errors allowed when connecting – the junction of the brick chimney and gas heating boiler, made with a piece of stainless steel pipe or corrugated, with a mandatory vertical section, length of at least 0.5 m. Permissible dimensions of operation of the horizontal section of the pipe are not more than 1 m. In total, all sections must be no more than 3 m long.

Learn the basics

You should familiarize yourself with SNiP 41-01-2003, which governs the construction of heating systems in private residences, before you begin building a brick chimney. Section 6.6 of this code of practice, which outlines all the requirements, chimneys, should receive special attention.

Furthermore, knowledge of this structure’s nature and the components it is made of is necessary for the proper chimney to be erected.

Flue pipes come in three primary varieties:

  1. Rooted. Chimneys of this type are placed on their own foundation. This is a stand-alone structure combined with a fireplace or stove.
  2. Nozzle. Such chimneys are mounted on the ceiling of the stove and are an integral part of the stove.
  3. Wall. This type of pipe is made in the walls.

Let’s examine the components of the most typical overlaid chimney. It includes:

  • An extension chimney, which is placed on the slab of the stove. The masonry of this section of the chimney is made with the binding of each brick in a row with the bricks of the next row. The masonry of this section is made almost to the ceiling slab, not reaching it 5 rows.
  • Next comes the masonry extension, without increasing the internal dimensions of the channel. This section is called a tongue and groove. The flue is extended from row to row until it passes through the ceiling slab.
  • On the flue (already in the attic room) is placed straight chimney – "riser". This part of the chimney reaches up to the roof.
  • To pass through the roof, an extension of the masonry "riser" is made, which is called "otter". It prevents moisture from entering the attic through the roof.
  • A straight section of the chimney is laid, which is called the "neck" of the chimney.
  • It, again, ends in an extension. An umbrella or a deflector is mounted on the header to prevent debris, precipitation, etc. from entering the channel.

An example of a standard chimney type with all of its components indicated is shown in the figure below.

Brick chimney as an engineering structure

Despite its unassuming exterior, the chimney is a sophisticated engineering structure that must adhere to strict regulations. They have to do with power, preventing fires, and efficiently eliminating hot gases. Consequently, getting acquainted with the stove pipe’s apparatus should come first when installing one in a wooden house.

Basic elements

  1. Internal chimney – is carried out from the ceiling of the stove to the level that is four rows of brickwork below the ceiling slab.
  2. Flueing – Expansion of the wall thickness of the chimney as it passes through the ceiling slab.
  3. External chimney – is conducted through the attic room up to the roof level.
  4. Otter – another extension of the wall thickness of the chimney, arranged to cover the gap between it, the roof purlins and its roofing.
  5. Neck – extension of the external chimney.
  6. Header – thickening of the walls, which plays the role of a deflector.

Requirements for the brick chimney

The primary one is the separation "from the smoke" between the structures that can catch fire. The entire length of a ceramic full-body brick is equal to 250 mm.

Strict verticality in the structure is the second prerequisite. It is not permitted to deviate from this by more than 3 degrees (per meter of height). Additionally, there shouldn’t be any cracks in the brickwork.

Chimney calculation

The internal cross-section is the primary criterion. It primarily depends on the capacity to evacuate heated gases. The width of the chimney should increase with the furnace’s power. For one kind or another of heating device, there are three sizes available.

  1. "Four" – a row of which forms four bricks. Cross-section 125 by 125 mm. Used for cooking stoves or low power heating stoves.
  2. "Five" – a rectangular chimney, formed by a row of five bricks. Cross-section 250 by 125 mm. Used for heating and heating and cooking stoves. It is not recommended to make chimneys for fireplaces smaller than this cross-section.
  3. "Six" – a square pipe, a row of six bricks. Section 250 by 250 mm. It is used for fireplaces and Russian stoves – wherever a minimum resistance to the movement of hot gases is required.

Height is the second most significant factor in the computation. Depending on where it is positioned in relation to the ridge on the roof:

  1. Pipes installed on the ridge or at a distance of no more than 1.5 meters from it, elevated above the roof 0.5 meters.
  2. Chimneys passing through the roof at a distance of one and a half to three meters to the ridge, make a height equal to it.
  3. If the distance is more than three meters, the angle between the ridge and the top cut of the pipe should be 10 degrees.

How much does it cost?

For three centuries, the roof-mounted brick chimney has managed to become a constant feature in the landscape. And based on subjective evaluations, a building with this level of completion appears far more appealing.

The only thing left to do is calculate the cost of adhering to the canons. The cost of bricks will be added to the overall cost of the job if you hire outside craftsmen. It’s also not a little one. For instance, laying one brick in St. Petersburg and the surrounding area will cost you between 50 and 90 rubles.

The price per piece of full-body single brick, brand M 150, used in masonry stoves ranges from 15 to 20 rubles.

If you prepare the mortar yourself, there is no cost.

A kilo bag of prefabricated masonry mix cost between 60 and 70 rubles. For ten to fifteen rows of pipe cross-section measuring 125 by 250 mm (sixes), one package will suffice.

Let’s compare the price per meter of a brick pipe with a cross-section of 250 by 250 mm and a metal sandwich pipe with a diameter of 250 mm. Exactly the kind that can be applied to the fireplace chimney device.

Brick (at a price of 15 rubles. per piece) Masonry mix Master"s work Total, rubles
Brick chimney 900 rubles 70 rubles 3000 rubles 3970
Metal sandwich pipe 3800

The prices are nearly the same, as you can see. Of course, you should also include the cost of the header, the otter, and the crawlspace’s masonry. However, it makes sense to spend the money on such a purchase because brick pipes have superior performance qualities, such as greater thermal resistance and lack of corrosion. Additionally, the cost of brick chimneys laid by hand will be nearly half that of sandwich pipes made of metal.

Step Description
Gather Materials Collect bricks, mortar, chimney flue liner, chimney cap, and necessary tools like a trowel and level.
Plan Placement Determine the location for your chimney, ensuring it meets safety regulations and is positioned correctly for efficient airflow.
Build Foundation Create a solid base for the chimney using concrete or bricks laid in a trench.
Construct Base Lay the first few layers of bricks in a square or rectangular shape, ensuring they"re level and plumb.
Install Flue Liner Place the chimney flue liner inside the brick structure, ensuring it"s centered and secured.
Continue Building Add more layers of bricks, staggering the joints for stability, and periodically check for levelness.
Install Cap Once the chimney reaches the desired height, install a chimney cap to prevent debris and animals from entering.
Finish Allow the mortar to cure completely before using the chimney, typically for several days.

For any homeowner, building a brick chimney is a major project that has both practical and decorative advantages. Your home’s insulation and heating system can be improved by building a safe and effective chimney by using the right methods and procedures.

Above all, make sure you are well-versed in the local building codes and regulations pertaining to the construction of chimneys. It is imperative that these regulations be followed for both legal and safety purposes. It’s also a good idea to speak with experts or seasoned builders to get advice and insights unique to your area.

Make durability and quality your top priorities when choosing materials for your chimney. High-quality bricks that can withstand weathering and high temperatures are ideal for building chimneys. Purchasing high-quality materials up front can protect your chimney from future maintenance problems and extend its lifespan.

When constructing a brick chimney, careful planning and design are imperative. Take into account elements like the flue’s size, location, and height in relation to the rest of your house. A well-designed chimney improves your home’s overall architectural appeal in addition to its functional efficiency.

Paying close attention to details is crucial when building. Proper mortar joints and careful bricklaying are necessary to ensure structural integrity and avoid leaks. To ensure consistency and strength throughout the chimney, take your time when measuring and aligning each brick precisely.

Last but not least, after the chimney is built, upkeep is necessary to maintain its longevity and functionality. Plan yearly cleanings and inspections to get rid of creosote accumulation and spot any possible problems. To avoid more issues, also take the initiative to quickly address any damage or deterioration that you notice.

To sum up, the construction of a brick chimney necessitates meticulous planning, close attention to detail, and compliance with safety regulations. By using the appropriate methods and strategies, you can build a chimney that enhances the beauty and character of your house while effectively expelling smoke and other gases.
