Groove for a gas column

The little things count when it comes to maintaining a warm and comfortable home. The installation of a gas column, an essential part of many heating systems, is one frequently disregarded detail. But, it requires a proper setup and cannot just be placed anywhere. This is where a gas column’s groove is useful. The effectiveness with which your heating system runs can be significantly affected by this seemingly insignificant feature.

So, what precisely is a gas column groove? Consider it as a specific area or channel where the gas column is snugly positioned within the structure of your house. It’s not just any old place; rather, it’s carefully thought out and placed to guarantee both safety and best results. This groove facilitates appropriate ventilation and maintenance in addition to stabilizing the gas column.

Now, you may be asking yourself, why even use a groove when you can just put the gas column anywhere it fits? The truth is that accuracy counts. The proper height and angle of the gas column are guaranteed by a well-designed groove, enabling effective heat distribution throughout your house. Additionally, by maintaining the gas column’s tight alignment, it reduces the possibility of mishaps.

There’s more to it than just functionality, though. Preserving the aesthetic appeal of your living area also involves the gas column groove. You can preserve a neat and polished appearance without compromising functionality by skillfully incorporating the gas column into the layout of your house. Furthermore, the groove can give your interior décor a stylish touch when combined with the appropriate materials and finishes.

In summary, the groove for a gas column is an essential part of the heating system in your house, not just a minor detail. You can simultaneously optimize efficiency, safety, and aesthetics by making sure that installation and integration are done correctly. For this reason, don’t undervalue the significance of this seemingly little feature when remodeling your current space or constructing a new house. It’s essential to your comfort and mental clarity.

Installation of a chimneine system

Installing the chimney in accordance with regulations will guarantee proper smoke extraction, boost the gas column’s efficiency, and—most importantly—avoid the possibility of fire and carbon monoxide leaks. Gas equipment is installed first when the structure is built. The following steps are involved in assembling the Chimpanzee system:

  1. Installation of the passage pipe in the nearest wall through which the chimney -free pipe will go. Installation of an angular element for switching to a vertical axis of the system. The connection of the chimneine pipe and part of the output of the column.
  2. On the outer wall, we install the pipe of the smoke system. The compounds of the pipe elements are fixed with clamps.
  3. For strength, we fasten the structure with brackets, the step between which should be up to 2 meters. We monitor the absence of deflections along the entire length of the smoke -haul system. We mount a protective cone (umbrella), which protects the chimney from sedimentation and extraneous objects. Install the revision window in the lower part of the vertical axis.
  4. At the end of the work, it is necessary to check the presence of normal traction. To do this, you can bring the lit match to the chimney and follow the movement of the fire. He must lean to the side, which means the presence of traction.

Internal installation of the chimney

The following are the traits of installing chimneys indoors:

  • preparation of the places of passage of the channel through ceilings and the roof;
  • the difficulty of collecting the structure and its repair;
  • the possibility of harmful gases entering the dwelling;
  • Fire safety and protection of wooden surfaces.

Prior to applying marking, the overlap and roof are marked, and a hole with the necessary diameter is cut. The ventilation pipe that originates at the boiler is then put together. Brackets are installed to allow pipes to be attached to walls with a step of 3–4 meters. Clamps are used during fixation. There is a metal flexible sheet protecting the channel section that goes through the roof. Insulation and sealant are used to isolate the junction. Fire resistance is a requirement for insulation. The pipe’s outer section terminates in a cone-shaped tip. The steel pipe ventilation system can be installed inside brick channels if the building is still under construction.

There should be a minimum of 50 centimeters between the horizontal section of the pipe and the gas column pipe. The vertical area’s length is less than 25 cm when the ceiling height is less than 2.7 meters or when traction stabilizers are used.

A metal plate protects the pipe’s point of contact with the roof.

Installing a metal chimney with your own hands

  • First of all, the distance required for the chimney is accurately measured, and special tubes, clamps for fastening are purchased, nodes for laying pipes between the ceilings, an adapter from a column and an umbrella for covering a place to exit combustion products;
  • The installation of the chimney from the lower part begins – from the connection to the gas column. For this, special adapters are taken, and the joints themselves are impregnated with sealant;
  • the pipe is joined, into which the valve is installed to increase the thrust;
  • Next, the remaining parts of the chimney are installed, fixed with clamps every 1.6 meters;
  • where chimney pipes pass through the layers of ceilings, install protective nodes to eliminate fires. The exit of the chimneys from the roof is thoroughly isolated with a plug.

Installation of hoods for a gas column and basic rules SNiP

Generally speaking, you shouldn’t discuss the installation too much because it’s all fairly straightforward.

  1. Find an acceptable place for the chimney (if the house already has a boiler or a fireplace with a finished hood, it is more reasonable to bring a new chimney to it).
  2. Calculate the necessary parameters suitable for the output of combustion products.
  3. Determine the traction set, based on the data of the gas boiler power, the number of processed gases removed from the pipe with a given power, the difference in temperature of the incoming air and the output gas, as well as the height of the chimney itself.
  4. Calculate the height of the ventilation, taking into account the type of gas equipment.
  5. Make a hole where the hood will pass and insert an asbestos pipe, the diameter of which should be more than 12 cm.
  6. Set the hood at least one meter higher from the surface of the roof (this will provide good traction).

Of course, keep in mind the SNiP rules as well. They claim that ventilation is mounted on walls or partitions that are separated by a unique non-combustible material, either inside or outside the space. If there isn’t one of these walls, an indigenous pipe or nozzle is installed.

Keep in mind that there should be a separate ventilation system for each heating appliance. There can only be an exception if the room has two floors with two heating units installed on each, and no more than two units can be connected to a single chimney.

Additionally, two gas stems may be connected to a single hood as long as the chimneys from the devices enter the ventilation at different levels and are spaced apart by more than 75 centimeters.

Ventilation of the kitchen with a gas stove

Most of the time, the natural ventilation for gas plates that is installed in all private homes and apartments fails to achieve its intended purpose. causes of poor design, construction mistakes, poor maintenance, and poor cleaning. To check if the ventilation in a kitchen with a gas stove is functioning, simply smoke a cigarette there and come back in 15 to 20 minutes. Strong smoke odor? It is therefore necessary to upgrade the system as the current one does not meet the requirements for kitchen ventilation with a gas stove.

Requirements for kitchen ventilation with gas stove

The kitchen with the gas stove (SNiP 42-01) must adhere to the following ventilation requirements in order to provide enough air exchange in the room with the stove:

  • Ceiling height of more than 2 m 20 cm;
  • The presence of a ventilation canal or window with an opened window in the upper part;
  • Under the door or in its lower part, the gap or hole with a total area of 25 square meters. cm.

Air outflow

The kitchen hood

Installing an extractor fan is the most popular solution for restoring normal ventilation above a gas stove. The air rising above the stove, food odors, and carbon monoxide will be stretched by the fan. Additionally, a broad hood umbrella will send the vapours straight to the duct. With a gas stove, the hood allows for forced exhaust ventilation in the kitchen. Hood prices vary widely and are influenced by factors such as manufacturer, additional functions, design, and power.

Two varieties of hoods exist:

  • with filtration and recirculation of air;
  • with the removal of the spent air outward.

Since the first type of hoods are not involved in air exchange, they cannot be referred to as a component of the ventilation system. However, the latter completely guarantee the exhaust air’s outflow. Instead of where fresh is. However, additional steps are needed for supply ventilation in a kitchen with a gas stove if plastic windows are installed.

The following formula is used to choose the hood’s power:

M is equal to O * 10.

ABOUT-The following formula is used to determine the kitchen’s air volume:

O = H * l * s

H – The room’s height, L stands for the room’s length and S for its width.

Documents pertaining to regulations state that installing mechanical ventilation for a gas boiler in an apartment building’s residential units is permissible without interfering with the common house ventilation system’s function. That is, the hood’s duct cannot be removed so that it fully overlaps the ventilation grill inside the mine. If not, the ventilation in the kitchen or gas boiler room will not work when the hood is off.

A special ventilation grill with a circular duct exit is used to solve the issue.

The video contains all of the connecting hoods’ secrets:

Air flow

The item "window supply valve" has been renamed.

Supply devices create the fresh air supply required for both human health and the regular operation of gas equipment.

The following kinds of supply devices are available on the market to ventilate a gas stove in a home or apartment:

  • The window supply valve. It is built into the sash of a plastic window, works automatically or manually. Prone to icing in particularly severe frosts;
  • Wall supply valve. For installation, a hole in the outer wall is required. There are models with air filtration, it can be automatic;
  • Improver. Hung on the lower sash of the plastic door, works from the network. Not only filters the supply air, but also warms it.

With our recommendations, you can install any of the specified supply ventilation devices for the kitchen independently, even if you have a gas stove or boiler.

Making and installing a chimney with your own hands

There are uniform guidelines for installing withdrawal channels for all types of columns and releases in any year.

Seeking advice from experts is advised before beginning any work. It should be kept in mind that only qualified service personnel are capable of connecting the column.

What materials are it better to make

It is impossible to save on the installation of a chimney for a water heater. First of all, inexpensive goods soon lose their usefulness. Second, they are identical in terms of the performance needed to effectively remove combustion products.

It is recommended that you focus on resources that fulfill the subsequent requirements:

  • strength;
  • Corrosion resistance;
  • water resistance;
  • refractory;
  • durability;
  • Flexibility and elasticity.

The majority of these specifications are satisfied by a double stainless steel pipe insulated with basalt wool.

Drawing and schemes

Plans are created on paper or assembled on a personal computer. The walls, ceilings, and roofs are measured roughly.

To precisely ascertain whether the structure complies with SNiP requirements, the drawing is created on a scale. Furthermore, the materials required for the fabrication of the smoke-removal channel from the water heating column are computed based on the scheme.

Size calculation

When performing calculations, one must consider that a minimum of 250 cm of vertical channel must be provided for water heaters with vertical pipes.

Furthermore, it is imperative to consider the following subtleties:

  • The diameter of the chimney is not less than the cross -section of the pipe;
  • the number of angles is no more than three;
  • The total length of horizontal areas is not more than 300 cm;
  • a small slope to the sides of the column is required;
  • The permissible slope when going around the building elements is 30 °.

Removing a chimney to a mine that is meant for ventilation is prohibited. There is a risk of an emergency or the house’s occupants becoming poisoned.

Varieties of chimney

The column’s operating principle serves as the primary criterion when selecting an exhaust pipe type. The majority of them naturally draw air into the burner from the surrounding space through an open combustion chamber. However, there are more costly and contemporary turbocharged water heater models available. An air pump is used to force air into the closed combustion chamber. As a result, different people use these two types of chimney pipes.

Since the burner in operating gas heaters with an open combustion chamber relies on ambient air pressure, they are referred to as atmospheric heaters. Forced air injection happens in turbocharged columns with a closed fireplace, which causes the burner to operate under pressure. This accounts for the hotel units’ second name, the depressed.

Exhaust pipes made of the following materials may be used in private homes and apartments to remove gases from an atmospheric type column:

  1. Vertical brick channels with ceramic or metal insert. Arranged in the thickness of the walls during the construction of the house.
  2. Stainless or galvanized steel chimney pipes are ordinary or insulated (sandwich).
  3. Enameled steel chimneys – for internal laying.
  4. Corrugated stainless steel pipes – to connect a column to an exhaust vertical shaft (“corrugation stainless steel” is called in the common people).

Enameled steel chimneys

Homeowners frequently connect a gas column using the least expensive method, which involves using corrugated aluminum foil pipe. On the one hand, foil corrugation lasts a long time, and a flowing water heater is a periodic device.

Corrugated stainless steel

However, thin aluminum can burn out at any time, posing a risk to residents’ health from carbon monoxide. As a result, it is not advised to connect the speakers to vertical channels using such gas chimneys.

By means of what are known as coaxial (double-circuit) chimneys, smoke gases are extracted. Their design is straightforward: a sizable gydery is created between their walls by the placement of a smoke-haired pipe with a smaller diameter inside a sleeve. This allows for ample air passage. Consequently, two streams flow in the direction of one another through the channels, exchanging heat.

The air is moved along the outer from the street and absorbed by the fan as the combustion products exit the gas column along the inner channel of the coaxial chimney that passes through the wall. The picture displays the double-circuit channel’s constructive diagram:

The device of the chimney in the apartment

There are certain subtleties in an apartment that you won’t encounter in a private home when installing and connecting a gas water heater. For instance, chimney shafts are uncommon in apartment buildings; instead, ventilation is found. And even though many residents do so, it is impossible to connect the flow heater’s gas output. And various inspections just don’t want to see this.

Entryway to the ventilation shaft

If there isn’t a designated channel in the wall, how can the chimney from the column be installed and connected correctly? The best way to achieve peaceful sleep is to install coaxial chimneys and purchase a booster water heater.

In order to avoid conflicts with the neighbors, it is also crucial to withstand the distances it has to windows and other structures. The table shows the profit intervals:

The task is made a lot easier if the apartment still has a chimney channel. Panel houses don’t have any combustible buildings, so you can install stainless steel corrugation safely to prevent it from sagging from the apparatus pipe to the mine entrance. Using clamps, a specific flange for the chimney is installed in the wall.

Proper connection: every unit connects using a separate channel.

Improper operation of the smoke exhaust system

  • Burning. The reason may be improper installation of a smoke -casing system or the use of low -quality materials.
  • Soot fire, as a result of a fire. The reason is the improper operation of the gas column. Carefully read the instructions for the operation of the equipment.
  • The formation of strong condensate. The cause of this phenomenon is poor thermal insulation of the flue system.
  • Bad thrust. The reason is the irregular design of the chimney or the selection of thermal insulation.

If you lack the necessary experience, the system installation should be left to the professionals. After that, you can enjoy the chimney’s proper operation. You will also shield yourself from a host of depressing outcomes.

Why do you need an hood for a column

A column’s hood

First of all, it should be known that regular speakers function perfectly normally even when there is only a little traction available in a ventilation pipe. An extra hood serves the following purposes:

  • Enhances traction. But experts argue that not all columns require an additional increase in traction, since the one that is already in the ventilation shaft, and so enough. If the craving is weak, then the reason for this may be a blockage in the mine. Therefore, in this case, to eliminate the problem, you just need to clean the mine. In other cases, the reduction of traction provoke adverse weather conditions. But, since they happen infrequently, it is impractical to mount an additional hood for such cases;
  • reduces the number of combustion products that penetrate the room during the operation of the unit. In this case, you can simply check the joints of the unit pipes, and if there is damage, eliminate this disadvantage. With normal natural thrust and lack of damage in the joints of the pipes, carbon monoxide does not get into housing.

As a result, installing a backup hood is advised in the event that the mine shaft cannot be cleaned. A periodic attenuation of the column indicates clogged ventilation.

Plan the house repair and the new kitchen "from scratch" and don’t rush into adding another hood. It is advisable to first verify that your column functions properly with natural traction, as an extra exhaust pipe consumes a lot of available space, detracts from the room’s aesthetic, and necessitates additional expenses and time.

Reasons for installing an hood for a column

A gas column without hoods can still function correctly because ventilation mines provide a tiny amount of traction that keeps the column in operation. Many people, though, favor using exhaust mechanisms.

The installation of a special hood allows you to achieve the following outcomes:

  1. The thrust will increase. This effect will be useful when the ventilation shaft is clogged and requires cleaning: in the absence of sufficient traction, the fire in the gas column will periodically fade, and only the hood will solve this problem.
  2. In some cases, the kitchen needs Provide draft, since the ventilation shaft does not provide sufficient air flows. Most often, such a problem occurs under inappropriate weather conditions, but since such cases are minimal, it is not always appropriate to spend money on installing an exhaust pipe.
  3. If you have a gas column and hoods in the kitchen, you can reduce the number of combustion products, which penetrate the room during the functioning of this equipment.

Do not rush to buy such an extract if you intend to fix your kitchen "from scratch." It’s possible that the gas column will function as intended and that the exhaust pipe will only encroach on available kitchen space, going against the principles of contemporary design.

If installing hoods is required in your situation, carefully consider the features that will help you avoid common mistakes.


There are numerous varieties of corrugated pipes available today. You can’t use everyone as a chimney. Environmental regulations and fire safety requirements are to blame for this. The most often used pipe types are listed below.

Aluminum pipes

In the past, abandonment was accomplished everywhere with an aluminum foil pipe. She has a 50–75 mm radius and is affordable, flexible, and robust. She accomplished her primary duty flawlessly and was incredibly useful for lying. Steel wire and aluminum corrugation are used to form aluminum pipes, giving the product its shape. With just a basic metal tape, it extended without any connectors. You can adjust the length of the chimney because its initial length is typically 70 cm and it can extend up to 3 m.

Its inability to tolerate high temperatures means that, while it is still frequently used for gas columns, it is not utilized for devices that run on solid fuel.

Stainless steel pipes

Owing to the previously mentioned flaws, the pervasive corruption was made of stainless steel. Its properties are in no way inferior to those of aluminum, and it significantly outperforms them in terms of fire resistance indicator. Pipe made of stainless steel can tolerate temperatures up to 90 °C.

Features of installing a chimney in an apartment and a private house

While the installation of a chimney varies between an apartment and a private home, it starts with taking all the required measurements and preparing the tool and components.

Chimney in a private house

Boiling gas boilers, which serve as both heating and water heaters, are typically installed in homes.

Be aware that SNiP controls chimney placement, imposing restrictions on the device’s length, height, and configuration. Before connecting gas equipment, the chimney installation regulations must be followed.

If the wall is composed of combustible materials, such as wood, the distance from the wall to the chimney should be at least 25 cm and no less than 5 cm if the material is resistant to burning. The space between the boiler and the walls that pose a fire hazard can be decreased to 10 cm by installing an asbestos or steel shield.

The chimney’s horizontal sections should not be longer than three meters combined. When a vertical chimney is needed to circumvent building structures, it may be installed with a 1 m protrusion and a 30 ° slope.

Three pipe turns maximum are permitted. When installing a chimney through a non-combustible wall, a portion of the wall is cut out using a specific, approved project, and non-combustible material is used to fill the opening left by the pipe.

A 38-centimeter-diameter through-hole is drilled in a wooden wall, larger than the diameter of the chimney. Firstly, it is stitched together using galvanized iron. Secondly, a heater made of basalt is positioned and stitched together using a sheet.

Attention: The chimney should be 50 centimeters from the ceiling if the house has wooden floors.

The chimney’s technological arrangement:

  • Boil the pipe of the required length and configuration.
  • Cut the hole of the diameter exceeding the diameter of the pipe in the wall. In this gap, set the sleeve that protect the wall from heating.
  • The space between the pipe and the sleeve is filled with asbestos or expanded clay.
  • Fix the pipe with a supporting ring at the intersection of the ceilings.

In the apartment

There are frequently chimney mines in apartment buildings, which presents a challenge when installing a chimney for apartments. It is not permitted to connect gas outlets to ventilation systems. The installation of a more contemporary turbine column with a coaxial chimney is the only way to address the issue.

When a chimney channel is present, the task is made easier: a clamp is used to secure the pipe from the corrugation, which is the desired length, to the gas heating device’s outlet. The pipe’s second end is fixed within the smoke channel.

When assembling a chimney made of different materials, it’s critical to plan ahead, connect all the pieces, secure with clamps, and apply sealant.

Why there is no traction in the gas column

  • Errors made during installation – several types of violations are common:
  • Air duct diameter – cannot be a smaller cross -section than that of the water heater pipe. The diameter is calculated by the power of the heat generator. The use of more than 3 repeated angles and adapters when installing the pipe is not allowed. Minimum chimney length 2.5 m. The pipe cannot be narrowed and the cross section is less. The diameter should remain the same for the entire length of the chimney.
  • Connections should be dense non -allowing leaks. Sealing at the site of connecting the column to the hood. A special heat -resistant sealant is used to seal the chimney at the junction of the joints.
  • The minimum distance from the gas column to the chimney 30-50 cm.
  • The dimensions (length) of the corrugation should not exceed 2 m. Throughout the length, clamps are set that prevent the pipe sagging, which will affect the characteristics of the traction.
  • The inconsistency of the premises by the technical conditions of operation of the column – use a gas water heater in the absence of traction in the chimney. Insufficient air circulation in the room affects the operability of the column. It is forbidden to install in one room forced hood and water heater. When installing metal -plastic windows, a supply valve is necessarily provided.

As per the current SNiP 41-01-2003, the recommended thrust range for the chimney is 1.96 to 29.40 PA.

How to check traction in a chimney

  • There is a revision window or grille located on the front or side panel in the column.
  • A sheet of paper, or a lit match, is brought to the hole. The flame should deviate towards the column. Leaf stuck to the hole.

How to check the traction sensor on the column

  • Inside the device is a bimetallic plate connected to a gas valve;
  • When overheating, the metal expands and gives a signal to turn off the gas supply to the burning device;
  • After cooling, the plate returns to the previous size, opens the valve.
  • A mirror is placed next to the location of the sensor, the surface of which should not sweat with the column on;
  • If the sensor is serviceable, when closing the chimney, the damper to ⅔ The water heater must disconnect.

Under what circumstances should the traction sensor not be disconnected? Carbon monoxide will enter the room when the regulator is turned off and leaks. The column cannot be turned off by the controller. Actually, there won’t be any protection for the water heater.

How to remove reverse traction in a column

  • install the check valve on the chimney;
  • drown out and dismantle forced fans;
  • During the operation of the column, open the windows;
  • make supply valves in metal -plastic windows.

Reverse traction frequently happens in the context of infractions committed when the column is being installed and connected to the smoke channels.

How to increase traction in a gas column

  • the pipe is insulated;
  • The height of the chimney increases.


Installing the chosen duct will require different work.

  • If you stopped on a steel pipe, then you need to buy the necessary adapters for it. To find out what length of the pipe is required, measure the distance from the column to the opening of the ventilation duct. Installation of the pipe and adapters is quite easy and resembles the assembly of the designer. To fix the duct and process its connections, use the sealant.
  • If you decide to use a corrugated duct, then you do not need to buy any adapters. The corrugation is stretched to the required length to connect the ventilation system and the column. If you need to add the length, for this, metal tape is used.

The chimney’s height must be precisely calculated in order for the gas column to function as intended. In the next video, how to do it right.

Component elements of the chimneine system

The chimney’s component parts

  • Umbrella (protective cone) – the upper element of the chimney.
  • Smoke pipe – the next part of the structure after a protective cone. There is a performance with a thermal insulation layer or without.
  • Passing pipe – necessary for isolation of the previous element from the wall of the house.
  • Brackets – necessary to fix the chimney.
  • Fitting clamps – connect the joints of the pipes.
  • Tee – necessary for the transition from a gas column to a chimney.
  • Revision window – allows you to control the condition of the smoke pipe.
  • Collection of condensate, which accumulates as a result of the chimney.

Field of application of corrugation for chimneys

  • Connection of gas boilers and columns.
  • Reorganization of the existing chimney.
  • Using as an adapter or adapter connecting the output pipe and an already installed smoke eating system.

Corrugated chimneys for gas boilers

  • Aluminum pipes are able to burn out after several years of operation. Therefore, if there is a need to connect a chimney from the corrugation, it is better to choose a sleeve made of stainless steel.
  • The material has poor heat -saving characteristics. To reduce the production of condensate, you will need to do heat and sound insulation on the corrugation pipe. To do this, you can use non -combustible mineral insulation 5 cm thick.Thermal insulation is wound on a pipe, closed on top with any foil reflector. Fixed with knitting wire.
  • To connect pipe segments of different diameters, special adapters are used.

Because the outgoing flue gases from condensing gas boilers are relatively cold, the regulations permit the use of aluminum corrugated pipes in the chimneys of these boilers. However, it is preferable to select a stainless steel pipe to guarantee increased safety.

Corrugation chimneys for gas columns

  • Diameter – in the technical documents to the column, the size and cross section of the pipe connected to the output pipe should be spelled out. It is strictly forbidden to use an aluminum pipe with a smaller section. This leads to increased heating of the structure and, as a rule, deformation of the walls, burning, loss of tightness.
  • Parameters – permissible maximum length of the corrugation corrugation when installing a gas column 3 m. The quality certificates should be spelled out the working parameters, including the possible surface heating temperature. If the temperature of the outgoing gases is 200-300 ° C, then to install a chimney for a gas column, you can use a corrugation of a pipe with a working mode of 350 ° C.

The best course of action is to install flexible stainless steel fire-guided corrugated pipes for gas column chimneys. The column’s exiting gases have a temperature range of 300 °C; if necessary, aluminum analogues can be utilized.

Repair of chimneys of corrugation pipe

  • Decrease in the volume of falling condensate. The metal is heated above the “dew point” much faster, therefore, the appearance of moisture on the internal walls decreases.
  • Lack of soot – smooth internal walls of the pipe do not allow soot to accumulate inside the chimney. The probability of fire is reduced. Soot, burning, heats the pipe up to 1000 ° C.
  • Elimination of depressurization-after 10-15 years of using a brick chimney, it loses its tightness. In the absence of traction, smoke goes into the room literally "from all the cracks". Conducting guillation leads to the restoration of the tightness of the system of smoke eating.

Using corrugation to connect to the main chimney

Ventilation for a gas column

Steel air ducts blend in nicely with the contemporary decor.

A chimney is a necessary component of ventilation for a gas column. It is constructed from steel, coaxial pipe, or corrugated metal. Since the coaxial chimney is thought to be the most efficient, there is a high demand for this type of gas column ventilation. This is a dependable system that has been operating faultlessly and successfully for many years. The power of the gas column determines the chimney’s features.

Any chimney used by the column consists of:

  • protective umbrella (crowns the structure);
  • the pipe itself (made with or without thermal insulation);
  • The passage pipe separates the pipe from the wall of the house;
  • fasteners;
  • clamps are installed on the joints of the pipe sections;
  • adapter from the pipe to the column;
  • audit window to check the condition of the chimney;
  • Condensate capacity.

The column’s instructions specify the parameters, which include keeping the inner diameter of the chimney constant throughout. The length of the chimney overall is four meters.

It is crucial to consider the weather; in a cold climate, warming the chimney is preferred. The end of the chimney is visible one meter above the roof when installing ventilation for a gas boiler or column in a private residence.

Gas column chimney requirements

  • The chimney outside the chimney should be made taking into account all the requirements of SNiP;
  • A chimney should be brought to the gas column;
  • The tightness of the drain of smoke should be ensured, otherwise gas leaks are possible;
  • The material for the chimney should be resistant to moisture and temperature;
  • The chimney should be rigidly and tightly fortified on the wall, without sagging;
  • The main thing that needs to be achieved when installing ventilation for a gas column is the uniformity of traction. The easiest way to achieve it is to use smooth pipes with a round section;
  • The main indicator for choosing a chimney diameter is the dimensions of the input;
  • The chimney is installed vertically, which provides excellent traction;
  • In the lower part of the chimney, a hatch for revision is equipped, at the same time condensation is allocated through it.

Installation of a chimney for a gas column

  • The passage pipe is installed in the wall, the rotation is attached to it by 90 degrees. The column itself is attached from the inside;
  • The chimney pipe is installed outside. This is done sequentially, one pipe from the bottom up. The joints are strengthened by clamps;
  • We evenly distribute the mounts along the length of the pipe and fasten them to the wall. The optimal distance between the mounts 2 m. The pipe should not bend;
  • We install an umbrella on the top, and in the lower part of the pipe the observation window;
  • At the end of the installation, check the thrust. We bring a lit match to the chimney. If the flame is sticking into the pipe, the work is done qualitatively.

How to choose an hood for gas boilers and columns

When installing a gas column, there are various types of pipes that must be used to install the ventilation system.

As a general rule, pipes with a minimum diameter of 11 mm must be purchased. The diameter of the pipeline directly affects how aggressively combustion products are removed when a gas boiler or running column is operating.

Investing in pipes measuring 13 mm in diameter would be the best course of action. If multiple points of water intake are equipped with more potent gas equipment, wider chimneys are installed.

The quality of materials used in the gas column’s exhaust of combustion products must meet predetermined standards. Work that is efficient, dependable, and safe needs:

  • Increased smoothness of the internal walls of the pipeline (equivalent roughness of not more than 1 mm), so that not only gases, but also Sazha freely leave communication. The roughness of the above permitted parameters creates favorable conditions for the delay of ash and soot, which leads to narrowing the lumen of the pipe and insufficient gas removal intensity.
  • The stability of pipes to the action of high temperature and the aggressive attack of chemically active combinations of combustion products.

The owner makes the final decision regarding the pipe material for hoods. It is influenced by current material capabilities in addition to pragmatic considerations.

Manufacturers provide pipes with varying features, costs, and lifespans:

  • Aluminum. Light, affordable pipes have the same disadvantage – they quickly burn out when working at high temperatures.
  • The hood made of galvanized steel is protected from corrosion, has a democratic price, but when working in the condition of a high -temperature regime, harmful substances can be allocated.
  • A good choice is the hoods of steel with enameled coating. These communications are highly resistant to temperature regime, impeccable smoothness of the inner wall, but not cheap.
  • Experts recognize the best selection for hoods for a stainless steel gas column. They are characterized by a long service life, excellent smoothness, resistant to temperature and chemical influences. There are different configurations, but the installation of stainless steel hoods are enough.

The future hood’s tightness is directly impacted by the quantity of fittings, which also affects compounds and possible air leaks. Class B density, which is the lowest amount of air leaks from the exterior, is required for the chimney. The pipe configuration for hoods is the final selection parameter.

  1. Ordinary pipes with installation on fittings,
  2. corrugated, flexible,
  3. coaxial.

The coaxial pipe is a complicated construction in which two pipes are inserted into one another with a diameter gap that is large enough. Combustion products remove the internal pipe. Clean air is forced into the room via the lumen between the inner and outer pipes.

The coaxial stainless steel extract has several useful benefits in addition to its higher cost:

  • Inner pipe isolation + supply of cold air prevents the pipe to heat up during operation. There is no need for additional thermal insulation, safety increases.
  • The room is replenished with the oxygen content, which “picks up” the gas column during operation.

A cheap two-channel plastic pipeline can be used as an alternative to an expensive coaxial steel chimney. Its service life is substantially shorter though.

Take note! The majority of contemporary boilers and gas columns use a closed fuel combustion system. Installing a coaxial hood is required for them.

Stainless steel hopper pipes are perfect for installing gas hoods in homes because they are easy to assemble, require few components, have excellent corrosion resistance, and are discrete in cabinetry. For gas equipment, these are the priciest and toughest chimney pipes available.

The choice of pipeline material

When purchasing an exhaust pipe, it’s important to consider the installation circumstances, the gas column model, the smoke exhaust pipe’s diameter, and the required pipeline section lengths. It is best to have a map of the water heater’s location with all distances indicated. This will make it easier to choose the components you need and, if needed, seek expert advice.

Connecting and smoke pipes must be constructed of non-combustible materials with an equivalent inner surface roughness of no more than 1.0 mm, per SP 60.13330.2012. Furthermore, they ought to be densely packed with the tightness class and prevent air leaks on the connections and in the areas that are close to the smoke channel. It is advised to use materials like stainless steel and ceramics.

The use of flexible metal corrugated pipes, roofing, or galvanized steel with a thickness of 1 mm or more, as well as unified elements included with the unit, is permitted in SP 42-101-2003.

Because condensate can quickly erode exhaust pipe material, it is imperative that it be resistant to corrosion. Less soot will accumulate on the inner surface the smoother it is.

Although the external surface roughness is not normalized, a smoother material for the connecting pipe will be more useful in terms of cleaning convenience.

Corrugated pipes, on the other hand, are widely used to join a gas column to the smoke channel. They are a breeze to work with and incredibly practical in tight spaces. By using them, you can successfully navigate around obstacles and complete hidden installations, such as putting equipment inside cabinets and using detachable panels to close pipelines.

Although 1 mm thick galvanized steel is a perfectly acceptable material, some people believe that galvanizing can identify dangerous materials when heated to high temperatures. Its application is therefore not recommended for models whose outgoing gases have a high temperature.

Steel exhaust pipes with heat-resistant enamel have a good track record. White shiny pipes blend in well with almost any decor and make a cute addition to any kitchen.

Stainless steel is the ideal material in terms of its aesthetics, durability, and compliance with all requirements. She is not in danger from burning, corrosion, dusting, or haphazard damage. Of course, that ends up being the most costly.

Types and structures

The speakers are separated into two categories in their design:

  1. With an open camera taking the air from the room. Its movement occurs due to natural traction.
  2. With a closed camera. The air is supplied to it with a turbine, and combustion products are initially isolated in the housing.

The selection of specific chimney types is determined by variations in the device.

These materials are used to make them:

  • ceramic pipes laid in brick mines;
  • stainless steel with insulation (sandwich) or without;
  • enameled iron for internal laying;
  • Corrugated aluminum pipe.

Every option has a different price, reliability, safety level, and service life.

Which is better to choose

There are several criteria that need to be guided when choosing a smoke removal system:

  1. The coaxial type is used to arrange closed stoves. It is a double pipe, air is drawn one at a time, and smoke is removed by the second.
  2. Monolithic pipes are used to install open -type columns. They are installed along the walls and ventilation shafts.
  3. A flexible corrugated canal serves to withdraw gas into a common chimney directly from the column. It is allowed to use it in rotary areas, when the temperature of the removable products is reduced.

It is advisable to settle on a robust, dependable, and long-lasting stainless steel. At any point, thin corrugation may burn out or tear.

Features of gas columns

Closed fuel combustion schemes are found in a lot of gas columns and boilers. Because of this, using coaxial chimneys is required, resulting in efficient air circulation.

The way the hood is made implies:

  • the installation of pipes is only vertically;
  • use of non -combustible materials;
  • lack of changes in the section of the air duct;
  • sealing joints with compounds resistant to high temperatures;
  • use of no more than 3 knees in the design;
  • Ensuring the integrity of pipes.

Columns with a forced gas outlet system are present. A fan is used to circulate air, and it turns on automatically when it ignites. There is no chance of combustion products falling into the space with such a system.

The hood’s joints must be sealed using only non-combustible materials.

Material for the manufacture of hoods

The primary characteristics of the materials used to make hoods are refractory and strength. This is required to prevent carbon monoxide and air from seeping through the pipe and into the room. These devices are typically composed of a length of approximately 3 meters of corrugated pipe with a diameter of 110 or 130 mm. Such material has the required ease and flexibility, making it very convenient. A unique metal tape is used to join two pipes together.

You can use steel or aluminum pipes instead of corrugated ones. In the latter scenario, enamel covering the hood is required to shield the steel from high temperatures. If there are any turns in the design, they should be made with the use of extra pipes and adapters.

It is important to keep in mind that ventilation pipes with turns contribute to decreased traction. Each time this happens, efficiency will drop by ten percent. There shouldn’t be more than three turns in total. Excessive corner rotation can cause the thrust to vanish entirely.

There are certain drawbacks to steel pipes. Therefore, condensation forms on the pipe’s surface when there are large temperature differences between the combustion products and the pipe’s surface. The pipe needs insulation in the winter or it can freeze.

The installation of an appropriate gas column groove is a critical component that is frequently disregarded in the realm of home insulation and heating. This minor but important feature makes sure that your gas heating system runs safely and effectively. By acting as a channel for the gas column, the groove permits adequate ventilation and guards against any leaks or other dangers. The longevity of your heating system and the safety of your family depend on the installation and upkeep of this groove. Whether you’re building a new house or remodeling an old one, paying attention to this detail can really help to maintain a safe, warm, and comfortable living environment.

Requirements for the installed chimney for gas columns

The stable functioning of the gas column can only be guaranteed by rigorous adherence to the chimney installation guidelines. For those who install the equipment without the assistance of professionals, this is a crucial moment. The following specifications need to be considered from the outset of construction if the chimney is going to be built in a suburban home.

  1. The design of the chimneys must correspond to the snaps.
  2. Each device must have its own outlet channel. As an exception, the connection of two devices is allowed, but at a distance of 0.75 meters.
  3. One hundred percent tightness of the chimney should be guaranteed (for example, such a material as brick, it cannot provide it).
  4. The traction inside the chimney should be even, constant. It is best to achieve this through the use of round pipes. In this case, the inner surface should not have roughness or other bumps.
  5. The material from which the chimney is made should be resistant to condensate. Otherwise, it is possible to destroy the walls of the pipe and leakage of combustion products.
  6. The input hole of the chimney must correspond to the diameter of the output of the column.
  7. Below the junction of the device and the chimneine pipe, provide for the possibility of installing a condensate collection, an audit for cleaning.
  8. The chimney must be insulated outside – this reduces the likelihood of condensate formation that reduces the life of the pipe.
  9. The number of bends (their rounding radius is equal to the diameter of the pipe)-no more than 3.
  10. The location of the pipe outside the wall is vertical. Deviation is allowed by 1 m or 30 °.
  11. If the pipes are suspended, then the mounting system should exclude sagging chimneys.When the pipe is withdrawn to the roof, it is necessary that the height of the chimney is> 0.5 m from the mounting surface (at a distance from the “crown” of the skate 1.5 m or less, the pipe should be 0.5 m). When installing at a distance from the top of the skate 1.5-3 m, it is not necessary to put the pipe above. Measurements must be carried out not on the surface of the roof, but counting from the axis that goes perpendicular to the skate! If the roof is flat, then the height of the chimney should be at least 2 meters. All kinds of “umbrellas”, “fungi” cannot be installed on the installed pipe, since the chimney should be direct, free.

Installation of corrugation for a gas column

It is imperative that installation workers become familiar with all safety regulations. The heating device’s and its component parts’ operational reliability will be greatly increased by adhering to all instructions.

The column needs to be positioned on the wall as high as feasible to prevent unanticipated events. It makes pre-settings for fasteners in order to accomplish this.

Holes are drilled with a perforator or drill, into which corks for screws are clogged. A heating device is attached to screwed screws. The subsequently connected steel or corrugated pipe for the gas column will become the element that will allow the production of combustion products into the chimney. Installation of a gas column is possible both in a private house and in the apartment according to the Rules of SNiP, exhaust pipes must be placed near the internal walls and partitions made of non -combustible material. If necessary, they can be placed on the outer wall, if there is no threat of ignition. And to avoid the appearance of condensate, resort to the use of safe insulation.

It is advised to use a radical or nozzle pipe for a gas column if the space does not allow for the exhaust channel to be placed inside the wall. If the gas device is guaranteed to operate consistently, connecting it to the furnace’s or another heating appliance’s chimney is deemed acceptable. There should be enough room in the ventilation duct section for the free removal of combustion products. The heating device can operate reliably and safely when an exhaust pipe is installed correctly.

It is imperative to ensure the availability of MA-shaped adapters for both the ventilation channel and the hood in the event that steel air ducts are installed. You should measure the distance between the gas column and the pipe and ventilation canal to ensure accurate dimensions. It is not necessary to use additional adapters in order to fasten the corrugation. A metal tape makes the pipe extension’s connection to the column possible. All components are easily assembled; the most crucial thing to remember is to closely adhere to the directions. Use specialized sealants to combine and seal the sealing of each component.

Step -by -step instructions for the construction of a smoke exhaust system

The ventilation of the space must be considered before equipment is put into service. Without forced turbo, air exchange, the extract is necessary. The commissioning of a gas boiler is impossible without it. Using a coaxial chimney as an example, we will look at how a gas boiler hood is installed in a private home. For this kind of hood, the pipe length from the boiler room to the street is no more than two meters.

  • When starting work, make sure in accordance with the installation of a gas boiler to the rules and norms approved by the inspection organizations in order to avoid remaking the entire energy sailor.
  • Select the appropriate material for the hood, taking into account the parameters of the gas outlet: the input hole of the gas boiler = pipe diameter.
  • Caling to the power of the fans and their quantity, given how long the hood, the number of knees in its structure, and the position in the space relative to the horizon, at what height is the exhaust pipe in the room.
  • Do not forget about the features of the budget technology specified in the data sheet.
  • All materials used in the work should be refractory and not succumb to corrosion.
  • Having made sure of the integrity of all details, we proceed to the assembly. We attach the chimney to the gas boiler pipe using the tee.
  • To build up the coaxial pipe and the connection of all its parts, special crimping clamps and refractory sealants are used.
  • The turbo exhaust is used if more than two knees are present in the geometry of the pipeline. This helps to preserve the efficiency of a gas boiler. Fan and all sensors are installed after installation of the supply pipe.
  • The installation of a coaxial pipe outside the building is no different from the mounting of a conventional plumper of the chimney.

Outside the building

The design of the hood for a gas boiler extends outside after an exhaust device highway has been installed within the home.

  • As soon as the pipe was brought out into the street through the hole in the wall, it must be closed with special metal plates. The remaining space between the pipe and the wall is filled with mineral wool.
  • Now install the tee. The lower hole is closed with a plug of revision for cleaning the pipe.
  • We increase the chimney to the desired length by connecting parts using a special sealant and clamps with gaskets. As the pipe grows, we attach it to special brackets.
  • Install a protective cone at the top of the chimney and additionally fasten the stretching in those places.
  • If the design of the chimney was not covered with special paint in production, this can be done at home. This is done to protect the metal from environmental exposure.

It’s crucial to take into account where the forced extract from a gas boiler or the room where the turbo elements are installed starts when placing an order for a street chimney system. You can watch the video to learn how to assemble and connect a gas column to the chimney system.

Inside the house

The installation of the coaxial chimney inside the house was previously detailed, along with some remarks. Combining two pipes using a street and indoor extension method is the sole step required. It is advised to use a specific metal tape for extra insulation.

One significant benefit of the coaxial chimney, which I would like to highlight, is that there are no extra holes in your home’s wall or roof.

Choice recommendations

The simplest method to connect the corrugation to the gas column and the exhaust mine hole, if we are speaking of the apartment. Because it’s the easiest and least expensive option, most users take this action. However, because they burn easily, aluminum corrugated tubes pose a serious risk. Such gas tracts are available for purchase and installation, particularly if the heater is not used frequently. They should only be inspected for damage on a regular basis, and installation guidelines utilizing a steel flange for the chimney—which will be covered later—should be followed.

Using a stainless steel or roofing pipe as the connecting section between the heater and the vertical shaft is far safer and more dependable. Although the products and their installation will cost more than corrugated, you will sleep soundly and they will last for a long time. It will also be less expensive to install a chimney for a gas column yourself if you do it in your apartment.

A slightly different scenario where private homes are exempt from the need to remove combustion products. Typically, during the building phase, they are given access to vertical mines made of red ceramic brick for this reason. It is recommended that the passage section of the mine be constructed using set-out ceramic elements or that an asbestos or steel pipe be inserted inside when installing the chimney. This will shield the canal’s inner brick walls from condensate’s damaging effects.

Gas columns and heating boilers must have their own chimneys at this point in the building’s construction.

Technically speaking, a smoke system consisting of steel-insulated pipes that are connected to the exterior wall or that go through the ceiling and roof is the best option for a private residence. Such an exhaust pipe gains in terms of cost, ease of installation, and efficiency but loses out on the aesthetics of a brick chimney. In these types of gas engines, the condensate is somewhat formed and flows into the lower part’s "pocket," which is outfitted with a unique drain crane.

One of the most important steps in guaranteeing the effectiveness and safety of your heating system is installing a gas column groove. To mount your gas column securely and reduce the chance of leaks or accidents, cut a groove that is the right size and placement.

The material of the wall or partition where the gas column groove will be installed is one of the most important factors to take into account. Selecting a robust material that can bear the weight of the gas column and endure the heat produced while it operates is crucial.

Determining the exact location and dimensions of the groove also requires careful planning and measurement. The gas column will be firmly anchored and readily accessible for maintenance and repairs if it is positioned correctly.

Paying close attention to details is essential when crafting the groove. To ensure that the gas column fits snugly, the groove needs to be clean, clear of debris, and smooth. Any flaws or sharp edges could jeopardize the installation’s integrity and be dangerous.

Ultimately, it’s critical to carry out extensive testing following the installation of the groove to guarantee that the gas column is operating as intended and that there are no leaks or installation problems. To guarantee ongoing safety and effectiveness, the gas column and groove require routine maintenance and inspection.
