Installation of a floor gas boiler – how to connect the boiler correctly

The layout of the independent gas heating system is considered for owners of new construction as well as apartments in high-rise buildings and private homes. A comfortable living can only be ensured by the heat supply design, which provides for the installation of a floor gas boiler or a hinged heat unit. Additionally, the cost of autonomous heating will be lower than that of centralized heat supply.

Before starting the installation of a gas boiler. It will be necessary to get a special permission, but the main thing is to remember that the safety of people in the house depends on how correctly performed work. All homeowners should remember that an independent device of a floor gas boiler is a responsible and complex matter, and the design of the corresponding permission is a mandatory procedure.
to set up the installation of a gas floor heating unit only on condition that there are financial capabilities to purchase a dual -circuit boiler with a boiler and automatic adjustment. It will also require a room that allows you to place a gas floor boiler there in accordance with the technical conditions.

A device of a floor gas boiler

It is best to leave the installation of a floor gas boiler to licensed experts from technical centers that specialize in offering this kind of service, as they will provide all the necessary paperwork, set up the space appropriately, and offer a guarantee for work completed.

The most basic gas boiler’s component is a heat exchanger and a gas burner, which makes it simple. Connecting the device’s gas, water, and chimney—as well as the power supply, if needed—will not be difficult. The primary prerequisite is to issue all required permits; failure to do so will result in penalties.

A good choice for your own home is a double -circuit heating device with a boiler and a set of automation. The device of this type of heating gas has an automatic system equipped with a microprocessor and a double thermostat, which monitors the air temperature on the street and in the house, and according to the parameters of the set settings, when the tenants are absent, the temperature regime is reduced to a sanitary minimum.
In such a boiler, gas consumption is about 30-70% less than in instruments with manual or semi-automatic adjustment. But such heat units still have a serious drawback – in the absence of power supply, the automation does not work and the boiler functions in minimum heating mode. So that there is no interruption with the heat supply of the house, it will be necessary to organize emergency energy supply, which will lead to additional expenses.

Features of installation of a floor gas boiler

Regardless of the model—floor or wall—the gas boiler should be installed in accordance with the standards and guidelines:

• Installation of a floor gas boiler is carried out in a separate room, which is called a furnace or boiler room, an area of at least 4 “squares”;
• ceiling height – from 2.5 meters;
• The volume of the room should be more than 8 m³ with a heating system power up to 30 kW, 13.5 m³ at 31 – 60 kW and 15 m³ at 61 – 200 kW;
• must be the presence of an opening window;
• The width of the door in the boiler room cannot be less than 80 centimeters;
• The furnace decoration should be carried out using non -combustible materials;
• The presence of a false floor or a falseboard in the premises is unacceptable;
• It is mandatory to ensure an air flow entering through a non -closing production, the cross section of which is 8 cm² at 1 kW of the unit power.

The volume of the furnace cannot be limited if the boiler has a closed combustion chamber. The guidelines and specifications must be followed, regardless of the boiler model.

When the wall or floor gas boiler connection diagram is created, the heating unit’s exhaust is shown in a different gas wrap (see "Scheme for connecting the gas heating boiler with examples"). Ventilation ducts cannot be used for this kind of thing because the products of combustion can seep into neighboring apartments in multi-story buildings as well as other rooms in a house. Additional prerequisites consist of:

• compliance with the length of the horizontal section of the gas transmit within the boiler room – no more than 3 meters. Rotation angles cannot be more than 3. The gas trap should have a vertical output rising above the roof skate or above the flat roof of at least one meter. When installing a chimney for a gas boiler, only solid materials resistant to chemical and thermal influences should be used, since when cooled, combustion products form aggressive substances. Layered materials, such as asbestos -cement pipes, can be used, but if they are located at a distance of more than 5 meters from the exhaust pipe;
• Before the installation of a floor gas boiler is performed, it is necessary that the boiler room is correctly prepared (more detailed: “Rules for installing a gas boiler – instructions for installing and connecting“). Space in front of the unit is left free. A strong, non -combustible metal sheet of 1 meter is laid on the floor under the heat unit. It is impossible to use asbestos -cement, since neither firefighters nor gas workers recognize it – it is abroad over time, and in addition, according to sanitary standards in the living room, it is forbidden to hold materials containing asbestos;
• There can be no places like cavities where combustion products or life -threatening gas mixture can accumulate. In the case when the gas device is planned to be used for heating the house, the gas workers will necessarily check the condition of the heating structure in the apartment or house. On horizontal areas, the pipes should be located under a slope, which does not exceed 5 millimeters per linear meter in the direction of movement of the coolant. At the highest point of the heat supply system, an expansion tank and air valve should be put. The heating structure should withstand the testing process under load equal to 1.8 bar.

The guidelines for connecting a floor gas boiler might seem complicated, but since gas is an explosive fuel, everything needs to be connected in line with the specifications.

In the following situations, installation of any model—even the most basic—is prohibited:

• if the apartment is located in an apartment building where there is no main gas station;
• когда в кухне обустроен фальшпотолок, который жильцы не хотят убирать, или капитальная антресоль. If the bottom of the mezzanine is made of cardboard or wood, it is easy to dismantle it.

If the apartment is not privatized, it can only be installed in a hot water boiler because a gas device needs a separate boiler room, which necessitates redevelopment—something that can only be done by housing owners.

You can install any boiler in your home because the furnace room can be situated outside the building. The boiler room should be outside the building; that way, there will be less need for the supervisory authorities to intervene and perform inspections. Installing a high-power gas boiler in a separate addition is permitted, enabling you to heat not just living rooms but also other areas of your home. Installing a wall boiler is a simple fix for homework because it eliminates the need for a floor heat unit, which requires a brick or concrete pallet with 50-centimeter sides.

Preparation for the installation of a floor boiler

You need to gather the necessary supplies and tools before connecting the floor gas boiler. Studying the operating manual and installation instructions for the unit will also be necessary.

From the supplies and equipment you must have on hand:

• cement and sand;
• shovel;
• a container for the preparation of the solution;
• drill;
• hammer;
• bolts and nails;
• wooden edging;
• Pipes for the gas transmit.

A gas device installation cannot begin until the installation site has been prepared. Installation of the floor heating unit requires a concrete foundation. An even metal sheet can be used in place of the screed. It is positioned beneath the boiler’s legs so that at least 30 centimeters of it protrude at the unit’s edges. The floor unit needs to stand precisely.

Boilers with a closed combustion chamber are installed in apartments situated in multi-story buildings or standalone structures, and the coaxial chimney leading to these boilers exits the room through the wall. Depending on the boiler model, the gas transmit opening is either on the top panel or the back wall. Since it is usually behind, it is simple to remove the chimney by drilling a hole through the wall.

Installation of a floor gas boiler

Once the base is ready, the device is set up on it so that you can maintain and inspect the machinery because of the space between the wall and the boiler’s back. Next, indicate where the chimney is. As per the regulations and specifications, the chimney pipe must be positioned at least 60 centimeters away from the window aperture. The requirement to prevent backward gases explains such requirements.

Often in many apartments located in high -rise buildings of the old buildings, as well as in small kitchens, gas equipment is installed directly under the window. If the supervision service was allowed this option of installation, the chimney must be installed away from the window or the opening window.
At the place where the location of the heat unit is noted, a hole is made with such a diameter that the chimney pipe passes into it (read also: “The correct device of the chimney for the gas boiler with your own hands”). The gas boiler is placed in place and mounted with the chimney. The pipe is placed with a slope directed towards the street. The size of the slope is learned from the manufacturer"s instructions attached to the equipment. Pipe tilt is necessary to remove condensate from the pipe, which is formed as a result of the temperature difference. When the installation is completed, the chimney pipe is fixed in the opening of the wall and closed using the solution (read more: “The diameter of the chimney for the gas boiler – the diagram and calculation of the size“).

In private homes, the boiler needs to be placed in a designated 30 centimeter-deep recess below floor level. A concrete screed is placed at the bottom of the pocket, and its walls are plastered and covered with non-combined material cladding.

How to install a floor gas boiler correctly

There are notable distinctions between the installation of a wall boiler and a floor gas boiler. Because the floor boiler is frequently more powerful and requires a more complex assembly plan, it is advised to install it with the utmost caution as this process calls for meticulousness and order. The installation of a floor gas boiler for the newcomer may require multiple days. The outcome needs to be assessed and approved by a Gorgaz employee before the boiler room is operational!

Everyone who owns a home once asked themselves how to connect a floor gas boiler to a gas boiler room. For these tasks, one person hires experts, and another chooses to complete the work independently. It goes without saying that if you don’t have the necessary experience, doing this is difficult, but it is doable if you follow the directions on the gas boiler.

It is advisable to become acquainted with the documentation that comes with heating equipment before attempting to connect a floor gas boiler.

The installation typically entails a number of setup tasks for the chimney’s equipment as well as equipment-related tasks.

Stage 1. Preparatory work

Boiler room dimensions are tightly regulated by normative documents. These documents specify that the room’s size must be at least 15 square meters. High ceilings, a ventilation duct, and a sizable window are also essential in the boiler room. A gas sensor should also be installed in the space. In the event of a leak, it will block the gas supply and respond with a sound signal. It goes without saying that engineering communications should be delivered beforehand to the boiler room.

We set up the equipment base.

Because floor gas boilers are heavy, it is best to install them on a level, stable surface that has been prepared beforehand.

The corresponding area of devices can be installed on a sheet of dense iron. In this instance, the sheet’s front should stick out by 40–50 cm.

The issue of how to set up a floor gas boiler is a crucial one. It is evident that we are discussing vertical and horizontal equipment leveling. To accomplish this, a unique building level is used.

Stage 2. Installation of the chimney

Boiler waste gases ought to be dumped outside onto the street. You must install the chimney in order to accomplish this. Here are some guidelines that ought to be adhered to:

• the material of the chimney needs a heat -resistant,
• The diameter of the chimney and the output parameters of the heating boiler should be comparable,
• Only non -combustible materials are allowed as a sealant,
• The height of the chimney is not below 5 meters, provided that the chimney is installed above the roof visor,
• Before assembly, you should carefully examine all the details for damage.

The primary prerequisites for constructing a chimney are adequate traction and the absence of cracks.

Equipment connected to a chimney should be free of cracks and gaps. The arrangement of the structure is vertical.

All components must be securely fastened to the wall after collection.

Stage 3. Binding of gas equipment

The installation of a floor gas boiler primarily relies on whether the system will be used exclusively for heating or in conjunction with a hot water supply system.

Binding is the process of attaching a gas boiler to technical networks. The most widely used binding technique is strapping with pipes made of polypropylene. Soldering the pipes will require the use of a specialized stapler. As you create the strapping, remember to follow the maxim "as few angles as possible."

You need a floor gas boiler strapping diagram before you can start strapping.

All equipment, input and output points for water, and connections for additional equipment are considered when developing the plan.

Sequence of clothing:

1. If a single -circuit of connecting a floor gas boiler is implemented, you need to connect the boiler according to the instructions from the passport. Creating a single -circuit scheme is quite simple, even if there is no experience.
2. In the case of a double -circuit system, it will be more difficult. Here, in addition to linking the boiler, you will need to link the hot and cold supply system, as well as a number of additional equipment.
3. The next step will be the linking of equipment with specific rooms. At this stage, it will be necessary to calculate the needs of each room in heat and water, depending on the area of the room and its purpose.
4. After the end of the binding, the system is launched in order to create the required pressure in it. On this installation of a floor gas boiler is completed. Further, testing and acceptance of work by specialists from the gas service is required.

Installing a floor gas boiler with your own hands according to technical installation standards

Many homeowners have the dream of having an autonomous heating system. The majority of them opt for gas heating, which has a major drawback in that equipment must be installed by qualified professionals. But only for devices that are connected does this apply. An individual can install a floor gas boiler on their own. How would one go about doing that? We’ll work it out.

Preparation for the installation of gas equipment

Those who are sure that the installation of a gas heating device begins with its purchase are very mistaken. Start with the collection of permits. You will have to do the following: Step No. 1: obtaining technical conditions and permission. It is necessary to find out whether, in principle, the installation of a gas boiler is possible in a particular apartment or in the house. For this, an application is submitted to the gas service with a request to carry out such a procedure. It must indicate the estimated annual volume of gas consumption. The document will be considered and as a result the applicant will receive a permit for installation together with technical conditions or a reasonable refusal. Gas boilers – the most practical and economical version of the heating of the premises. Can be used both in an apartment building and in a private house Step No. 2: Creating a project of a future installation. First, it is advisable to determine the brand of the counter and the boiler, but you should not purchase them yet. After which the installation project is ordered. It is carried out on the basis of the previously obtained permission for specific equipment. The document must indicate the connection schemes of equipment, and the gaskets of the highway inside the building from the connection point of gas communications. Only a licensed company has the right to engage in the project. Step No. 3: Obtaining approval with the gas service. The new project must be coordinated with the gas service that serves the site on the territory of which the house is located. The procedure usually takes a maximum of three months and at least a week. At this stage, gas equipment can already be purchased, because in addition to the project, you need to provide such documents for approval:

• technical passport of a gas boiler;
• Certificates of conformity and sanitary-hygienic;
• instructions for the operation of a heating device;
• Conclusion of examination on the conformity of the device all technical requirements.

Obtaining these documents is quite easy. The producer invariably affixes them to its goods. Upon completion of the inspection process, the applicant is handed an agreed-upon project, which in this instance will have a unique seal applied to it. A list of actions to modify the project must be included if the document is not agreed upon. Following their execution, re-approval takes place.

A dedicated top-down room that is enclosed with non-combustible materials must be set aside in order to install the floor boiler.

The rules for arranging a furnace room

The gas boiler is only installed in a specifically designed room known as the furnace, per the most recent SNiPs. This rule cannot be disregarded because gas boilers are considered potentially hazardous equipment and need to be handled with extreme caution. If not, there will unavoidably be consequences and possibly even emergencies.

The most ideal way to install a floor gas boiler is to set up a boiler room that is separate from residential buildings and has supply and exhaust ventilation.

Finding a location for the boiler installation is the first step. Single-circuit heating appliances with a maximum power of 60 kW may be installed in any room of the building, according to the instructions. The majority of floor gas units are single-circuit, t.To. exclusively intended for heating system maintenance.

In the kitchen, double-circuit models of any power are not permitted. These are miniature boiler rooms complete with an expansion tank and a mounted security group. It is set up for them top-down. Any floor can accommodate the equipment installation as long as its total capacity stays below 150 kW.

Only the ground floor or the basement may have more potent installations or instrument groups. In any event, it is not permitted to install gas heating boilers in bathrooms, living rooms, or hallways. There should be a set of dimensions for the combustion room. The formula to determine its minimum volume is 0.2 m³ multiplied by 1 kW of the device power, with a minimum of 15 m³.

If the furnace room’s walls are composed of combustible materials, they should be sealed with a specific refractory lining.

Furthermore, the following requirements are laid out for the room:

• The minimum width of the doorway should be 80 cm;
• minimum ceiling height – 2.5 m;
• The degree of fire resistance is not less than 0.75 hours;
• the presence of natural light, which is calculated as follows: 0.03 kV. m of the area of the window for every 1 cubic meter of the volume;
• the presence of a gas analyzer associated with an automatic valve, which will block the gas supply during leakage;
• arrangement of effective ventilation;
• The door or wall leading to the next room should be equipped with a ventilation grill, the area of which is determined by the formula: for each kilowatt of the heating device, there are 8 sq. see structure;
• ensuring free access to the heating device and auxiliary equipment for repair and maintenance work.

To satisfy the requirements for a furnace room for a boiler with an open combustion chamber, these conditions must be met. The area of the room is unimportant and the ventilation requirements are less stringent for units with closed chambers because the air they use for work comes from the street rather than the room. The top has an equipped gas station. Its horizontal area in the space shouldn’t be more than three meters.

A gas boiler’s installation procedure is mostly determined by its device. The device’s general layout is depicted in the figure of such equipment (+)

Furthermore, there can be no more than three turns. The chimney’s vertical yield is at least one meter higher than the level of the flat roof or the skate of the pitched roof. The materials used in the design should be able to withstand strong chemical and thermal effects. Only places farther than five meters away from the exhaust pipe can be used for multilayer materials, such as asbestos-cement pipes.

The furnace room shouldn’t have any niches or cavities created by horizontal surfaces. This is where frequency products can build up, which is extremely harmful to people. There should be room in front of the heating appliance. A metal sheet, at least one square meter in size, covers the floor in front of it. These uses of asbestoscene are prohibited due to its rapid abrasion and health risks to humans.

The majority of floor gas units are made to heat the coolant in heating systems that use both artificial and natural circulation.

Preparation of the premises for installation

It is necessary to complete all tasks associated with setting up the heating system, installing radiators, wiring the water supply, and, if applicable, installing warm water floors before beginning the installation of a heating device. Sewer and electricity systems should also be fully installed. Additionally, the boiler room’s premises need to be ready. Under a gas boiler, either a strong floor made of cement screed is installed, or an independent foundation is prepared.

The final choice is not the ideal one. If the walls, floors, or both are decorated with combustible coatings, you should take extra precautions to prevent potential fires. Non-combustible linings, such as asbestos, are used for this. They are composed of roofing sheet steel and are placed over a refractory gasket. The latter’s sheet cannot have a thickness of less than 3 mm.

Different floor boiler types have different numbers and kinds of auxiliary equipment. The figure depicts a potential setup for the system using a wall unit.

In this instance, the insulation should extend at least 100 mm beyond the device case’s dimensions all the way around. There should be a minimum of 100 mm between the heating device and any non-combustible wall. It is also controlled how far the automatic controls, burners, and protruding pieces of reinforcement are from the wall on the other side. It must be one meter or more.

The floor needs to be shielded from potential fire if it is composed of combustible material. This is accomplished by using a platform made of concrete blocks. It needs to be at least 100 mm tall. A steel sheet with a minimum thickness of 0.8 mm covers the elevation on top. Special refractory slabs can be used to set up a location for a device’s installation.

Furthermore, installing an auxiliary equipment is advised as the boiler may interfere with it otherwise. It is best to carry out the placement plan ahead of time in order to consider all the details of the setup. This plan calls for fasteners to be placed on the walls and floor before the required equipment is installed. In the final turn, the heating device is installed and connected.

Options for setting up a chimney for various kinds of gas boilers

Pocial lifting: Arrangement requirements

It is best to prepare a chimney before installing a floor gas boiler by hand. It is best to place the heating appliance on the base that has been prepared so that there is enough space between its body and the wall to allow for inspection and maintenance. Next, draw a rough outline of where the chimney is. The boiler cannot be installed; instead, markings based on computations must be made. There are a few subtleties to consider in this instance.

The chimney and the hole for it should, first and foremost, precisely match the type of floor boiler. As a result, a separate -type chimney with a cross section that matches the device’s power is installed for modifications involving an open combustion chamber. For instance, a chimney with a cross section of 160 mm is chosen for devices with a power of 40 kW or more, and the pipe diameter for devices with a power of less than 30 kW should be at least 140 mm.

Particular coaxial chimneys are installed on devices having closed combustion chambers. The manufacturer consistently specifies the required chimney diameter in the device’s technical documentation. Furthermore, it is important to keep in mind that the pipe connecting the chimney and heating boiler should not be longer than 0.25 meters. It is also necessary to arrange the closing hole through which the structure will be cleaned.

It is imperative to strictly follow all fire safety regulations when setting up a chimney.

A multi-story building’s boiler installed in one of the apartments must be assigned to a common chimney. Gas services won’t give the go-ahead to install the boiler if there isn’t one. It is much simpler in a private home. This is where the chimney of nearly any design can be installed. Its effectiveness and safety are crucial.

The chimney pipe cannot be mounted close to the window opening per the current standards. There is a minimum of 0.6 meters separating them. In order to rule out the possibility of the exhaust gases being brought back into the room, this is required. In actuality, supervisory services occasionally permit equipment to be installed directly beneath windows. In this instance, it’s imperative to make sure the exhaust pipe is as far away from the window or opening window sash as feasible.

When it comes to improving their heating systems, homeowners may want to consider installing a floor gas boiler. In addition to providing effective heating for your house, it also has advantages in terms of energy and space efficiency. A floor gas boiler can greatly improve your comfort during colder seasons by delivering even heating throughout your home.

A floor gas boiler’s ability to save space is one of its main benefits. In contrast to conventional boilers, which need a large amount of space to install, floor gas boilers are small and can be tucked away neatly. This frees up valuable space for other uses, which is especially advantageous for homeowners with limited space. Furthermore, the compact design facilitates easier maintenance and servicing while saving time and effort.

Moreover, floor gas boilers are renowned for their low energy consumption. These boilers use natural gas to heat your home effectively and with the least amount of energy. In the long run, this lowers your utility bills and lessens your carbon footprint. Choosing a floor gas boiler is in line with initiatives to cut down on energy waste and encourage environmentally friendly behaviors, which is in line with growing concerns about environmental sustainability.

The flexibility a floor gas boiler provides in terms of heating your house is another benefit of installing one. If you have baseboard radiators, radiant floor heating, or even a mix of heating systems, a floor gas boiler can work well with any configuration to deliver reliable warmth. This adaptability guarantees that a floor gas boiler can provide dependable performance regardless of the design of your house or the amount of heating you require.

To sum up, installing a floor gas boiler has many advantages for homeowners looking for dependable and effective heating solutions. With its compact design and energy-efficient functioning, a floor gas boiler provides an economical and useful solution for maintaining a warm and cozy home. Homeowners who select this option can benefit from better heating performance as well as support environmental conservation initiatives. A floor gas boiler is unquestionably something to think about when building a new home or renovating an old one.
