Despite numerous warnings that installing a wall gas boiler, must be carried out by specialists with the appropriate license, often installation is carried out independently. In order not to encounter unpleasant consequences in the form of gas supply shutdowns and penalties during preparatory and installation work, you will need to comply with the standards described in SNiP.
Norms and rules for installing a mounted gas boiler
Construction standards and rules for installing mounted gas boilers are described in (SNiP 31-02-2001) and. These regulatory documents describe general provisions related to location, fire and operational safety requirements.Additional instructions regarding installation work are contained in the installation manual supplied by the manufacturer of the unit.
Before you begin installation wall-mounted boiler heating with your own hands, you will need to fulfill several prerequisites:
- Obtain technical specifications for installation. The gas service must check the possibility of connecting the heating unit to the central line.
- Make a project. The need for a project for installation exists in every case, with the exception of situations when the heat generator is changed to one identical in power and model.
- Make approval - after preparing the project and receiving technical conditions, the documents are submitted for approval to the Gaznadzor authorities. If everything is in order, permission to install is issued.
After receiving the approval results, you can begin installing a wall-mounted gas heating boiler with your own hands. For the work to proceed with least violations, take into account several current requirements related to:
- With installation height.
- Fire safety requirements.
- Instructions regarding interior decoration boiler room
At what height should a gas boiler be hung on the wall?
When installing a wall-mounted boiler, you need to take into account the distances specified in SP 42-101-2003. In particular, the standards stipulate that from the base of the floor to the burner device there must be at least 0.9 m and no more than 1.2 m. In fairness, it is worth noting that the requirements apply to flow-through gas water heaters, but gas workers apply these standards to boilers. According to the instructions, minimum distance to the floor from the bottom of the body should not be less than 80 cm. When determining the location of the boiler, one more parameter is taken into account. Minimum height installation, determined by the distance from the chimney duct. The requirements stipulate that the boiler must be lowered down by at least two chimney pipe diameters. As a rule, the heat generator is installed in the range from 0.8 to 1.8 from the floor level.
Fire safety when installing a mounted boiler
When installing a wall-mounted gas boiler, fire safety requirements are imposed. Minimum fire breaks are provided:- At least 10 cm from the surface of the wall on which the unit is mounted.
- From the opposite wall, at least 40 cm.
Between the room used for the boiler room and the living rooms, a partition made of non-combustible materials is installed, with high degree fire resistance. When connecting to a pipeline, a corrugated metal pipe is used. Hoses that are completely rubber or protected by metal braiding are prohibited.
How and with what to finish the walls behind a gas boiler
According to the joint venture, the wall in the boiler room under the boiler can be sheathed with an asbestos board covered with stainless or galvanized steel. The protective screen should protrude along the perimeter of the boiler by 10 cm. It is allowed to cladding with brick or concrete wall, ceramic tiles, or plaster. The requirements for finishing materials, when installing a wall-mounted boiler used for the ceiling. According to existing standards, it is prohibited to use plastic for cladding or to cover the ceiling with wallpaper. Installation of gypsum fiber or plasterboard boards, followed by leveling plaster mixtures and puttying, and painting with water-based paints.
If a gas heat generator is installed in a wooden house, the safety requirements become more stringent. When installing wall mounted boilers, the wall is closed basalt insulation, at least 5 cm thick. The top is covered with sheet steel.
Thermal insulation material for installing the boiler on wooden wall, be sure to choose among non-flammable materials, with heat resistance and the ability to withstand heat over 1000°C. For work, basalt (not mineral) wool is optimal.
Wall materials when mounting a gas-mounted boiler
The most common installation errors are related to insufficient fixation of the heat generator to the wall of the house. Existing standards indicate the need for rigid installation of boiler equipment. The boiler must be firmly fixed to the wall, strictly observing the vertical and horizontal levels.The fastening requirements for installing a wall-mounted gas boiler largely depend on the material of the walls. Installation standards for wooden, plasterboard, reinforced concrete, brick, and hollow walls are specified separately.
How to hang a boiler on a wooden wall
According to “Apartment-to-apartment heat supply of residential buildings with heat generators on gas fuel", you can hang the boiler on a wooden wall, provided that the following conditions are met:- Material with a high degree of flammability, in the place where the boiler is installed, is treated with pyrine retardants.
- The wall is covered with plaster mixtures with minimum thickness 15 mm, or roofing steel over asbestos sheet.
Correctly hang the gas boiler on a wooden wall, installing an additional reinforcing beam placed under the facing material (lining) to ensure reliable fixation of the heat generator.
How to install a boiler on a plasterboard wall
A plasterboard wall is made by attaching sheets to a metal structure and implies the presence of voids. Firmly fixing the heat generator to drywall is problematic, but possible. At the stage of manufacturing the metal frame, a place is provided for installing the boiler. The mounting point is reinforced with a wooden beam and a metal profile.There are special fastenings for gas boilers to a plasterboard wall, which are plastic stoppers, screwed directly into the facing material itself. Installation anchors are screwed directly into the plug. As practice shows, ready-made fastenings become loose over time and lose the strength of their fixation to the wall.
How to attach to a reinforced concrete wall
Reinforced concrete is the optimal wall material for installing gas heating boiler. Precast concrete structures are durable and belong to the group of NG (non-combustible) materials. To install the boiler, no additional conditions are required.The work is carried out using metal anchors, through which the mounting plate is fixed strictly according to the level. The boiler is hung on the prepared platform. Reinforced concrete wall suitable for installing any type of heaters: high power, with a built-in storage boiler, etc.
How to hang on a brick wall
The standards separately stipulate the conditions for installing the boiler on brick wall. Brick is a non-combustible material, therefore, the heat generator can be installed directly on the wall. But sometimes, when putting a boiler installed in this way into operation, certain difficulties arise.To satisfy all the wishes of gas workers, installation is carried out as follows. The walls are plastered. While plastering the surfaces, a plate is installed for mounting the boiler. After plastering, it remains to stick out from the wall seat(two bolts), on which the boiler is installed.
Fastening the boiler to a wall made of foam concrete, gas silicate, aerated concrete
To hang a wall-mounted gas boiler on a wall made of blocks of foamed porous material, several methods are used:- Mounting fasteners are installed during block laying. The installation of the boiler is carried out strictly after the mortar masonry mixture has completely hardened.
- Special “screws” for foam concrete are used. In their structure, they resemble similar plasterboard plugs. They have a deep thread with a large pitch and are hollow inside. After screwing into foam concrete, gas silicate or aerated concrete, any anchor can be screwed into the screws.
- Use of hairpins - in in this case, two studs are installed apart from each other on required distance. On each side of the wall, a strip is installed, secured with bolts.
- Use of chemical, liquid anchors. Another option that provides the most durable fixation, but requires certain financial investments.
How to secure a chimney for a wall-mounted boiler
The rules for installing a chimney depend on what type of boiler they plan to install. Atmospheric heat generators use natural draft. Boilers with closed camera combustion units are connected to a coaxial chimney, and combustion products are removed and air is taken in using a forced method.Features of the work are reflected in the connection requirements: 
To fix chimneys, ready-made fasteners are used with the ability to change the distance to the surface.
What is needed to install a wall-mounted boiler
Self-installation of a gas boiler is possible only if you have the necessary construction tools, consumables and certain technical skills. All work is carried out in strict accordance with the step-by-step plan and boiler installation diagram given by the manufacturer in the operating manual.To complete the work you will need:
- Construction tool– you will need: a hammer drill with a set of drills, building level, tape measure, pencil, adjustable wrench. When connecting to the mains: voltage indicator, insulated screwdrivers, pliers. For the substrate: asbestos sheet, roofing steel, basalt insulation.
- Fasteners and Consumables – a mounting strip, metal or chemical anchors, and studs are required. To connect to the central gas main, you will need a corrugated hose.
To satisfy the requirements of gas workers, the connection must fully comply with the requirements specified in the relevant SNiP, SP and PPB. Some nuances associated with installation depend on the region, therefore, before installation, it is worth consulting with your local gas inspector.
In all cases, wherever it is planned to place the gas boiler, on the floor or on the wall, installation is carried out accredited specialists from Gorgaz.
Gas supervision will allow installation, only if there is a certificate of conformity purchased equipment.
Installation of a wall-mounted gas boiler. Materials and tools
Having chosen the model you like, ask how to mount it on the wall and What is included in the kit for this? to the boiler (hooks, power dowels). If the heater is sold without mounts, you will have to purchase them additionally.
Refuse to purchase if the unit is manufactured not a very reputable manufacturer. Either this is a novice supplier, or, more likely, not particularly concerned about quality.
After paying for your purchase, you can take it home and begin mounting it on the wall. To do this you will need tools:
- electric drill or hammer drill;
- metal pipes;
- building level(preferably laser).
Using the latter, they check how level the unit is installed. This is especially important for condensing gas boilers. The slightest deviation from the vertical guarantees breakdown, and in the near future.
Preparing the installation site
It should be remembered that the room where the gas boiler will be installed is considered explosive and must meet many criteria established by law. Therefore, before placing an order, you should make sure that this is possible in your home, otherwise the purchase will become absolutely useless: Gorgaz will refuse to approve the procedure.
Usually a wall-mounted boiler is installed in the kitchen. Except ventilation and through hole on front door(and in all cases it should go outside), pay attention to the wall itself. Make sure that it is strong and can withstand the installation of power fasteners, and even the boiler on it. For this reinforce the wall with wooden planks. The wall covering should be non-flammable. If there is a risk that it will catch fire in a fire, a layer is placed on the wall non-flammable material, then the boiler.
Photo 1. Approximate dimensions of a wall-mounted boiler and standards for its placement in relation to adjacent walls, floor and ceiling.
The unit, according to the standards, approximately 45 cm from the wall. Therefore, it must be mounted not directly on the panel, but on bars previously attached to the wall. Height from floor must be from 0.8 to 1.6 m. The remaining walls are tiled with ceramic tiles for aesthetics.
Attention! When installing a condensing gas unit, you must remember that it hang with a slant away from you, that is, the distance between the wall and the boiler at the top is slightly less than between the wall and bottom unit.
Hanging the boiler
The installation procedure consists of the following steps:
- unpacking boiler;
- reconciliation of markings on the case with data in the certificate and invoices for the device;
- screwing the bracket or other suitable fasteners;
- removing factory plugs from the unit;
- flushing internal pipes.
Now the boiler can be hung on Right place. Check horizontality boiler, adjust its position if necessary.
All that remains is to connect boiler to the system. If the master has already come on call, you can involve him in the work.
Chimney in a private house
The most common boilers found in homes are with closed firebox. This is understandable: they are easier to use, it is easier to connect them to the chimney - you just need to screw them on coaxial pipe. In private houses, the coaxial chimney is removed out through the wall.
Photo 2. Diagram of the smoke exhaust from a gas boiler through the nearest wall. Movement shown flue gases and air.
There are no strict requirements for the hanging height of the pipe, since draft is provided by the built-in fan. An open firebox implies the installation of an individual chimney, and Special attention you will have to pay attention to the cross-section of the pipe.
Attention! When purchasing a pipe, look at what it is made of. Suitable for work only wear-resistant materials, not afraid of the vagaries of temperature and the effects of combustion products.
Connection to the heating system
What needs to be done actually the same as when connecting heating. The difference lies in the taps and pipe diameters.
A filter is placed on the “cold” pipe, which will prevent dirt and metal particles from entering the heater.
Shut-off valves with detachable connections (so-called American women). It is much easier and faster to work with them, and if the faucet fails, it is easy to replace it with a new one.
Cold pressure pipes connect on the left, orienting from the center of the unit, hot - on the right side.

The gas line branch is connected with a flexible connection to the pipe on the heating unit. Shut-off valve must be equipped with a hermetically sealed filter. Sealing threaded connection carried out using paint and tow.
Do not use rubber hoses, they do not last long. Usually the Gorgaz representative stipulates this at the very beginning. Best suited corrugated hose made of of stainless steel .
In the room where the wall mounted heating device, required gas sensor, connected to relay. If a leak occurs, the sensor gives a command to block the gas.
Will work at the same time sound alarm , notifying the owner of a breakdown.
Advice. This part of the work, as well as the first launch, is mandatory entrusted to an accredited representative of Gorgaz with permission from a self-regulatory organization!
Double-circuit and single-circuit gas boilers
Differences in operating principle of these two units are as follows. Dual-circuit the heater will not only provide hot water from the tap, thanks to it, all systems work as before, as if the hot water had never been turned off - This includes water supply, batteries, and even heated floors. The heat exchanger heats the water coming from the cold supply system.
Photo 3. Diagram showing the differences between single-circuit and double-circuit wall-mounted boilers. The first requires a boiler.
Dual circuit unit only contains three-way valve , which regulates the direction of coolant flow. The heated water is directed towards the central heating. When a hot tap is opened, a sensor inside the unit switches the three-way valve to another position - water flows into the heat exchanger, where it heats the water.
Attention! Bye hot tap open, the so-called a priority hot water , that is central heating closed. Users often regard this nuance as an inconvenience.
So that you don’t have to wait for a hot stream (usually it appears half a minute or even more after opening the tap), It’s better to buy a flow-type boiler with built-in boiler. However, this option is only suitable for apartments or small houses. For a large mansion or estate it is unprofitable.
Single-circuit The boiler is only useful for heating cold water coming from the water supply.
To date gas boilers and columns are used everywhere both for heating water and for heating houses. For the most part, separate units are used for heating and hot water supply. single-circuit boilers or one single-circuit boiler and boiler indirect heating, which creates certain inconveniences in their placement. Therefore, in houses and apartments with low hot water consumption, the installation of double-circuit gas boilers, which combine water heating for both household needs and heating, is becoming increasingly popular. The installation of gas boilers is associated with a number of specific difficulties, related more to compliance with the norms and requirements for boilers than to the process of their installation.
The design of double-circuit gas boilers is essentially similar to the design of a conventional single-circuit one, where gas-burner heats the heat exchanger with coolant. The main difference is the ability of double-circuit boilers to simultaneously heat water for heating the house and for household needs. This is achieved through the combined placement of pipes for heating and hot water supply in the heat exchanger.
At first glance, the heat exchanger double-circuit boiler is a regular coil with a radiator grille. But it is necessary to note the following: the coil of a double-circuit boiler is most often a combination of 2 in 1 pipes. Inside the main pipe through which water for heating flows, there is another one for hot water supply. It should be noted that there is one more important point. Water in such a double heat exchanger circulates in opposite directions in each of the circuits. This was done specifically to improve heat transfer and this must be taken into account when designing and connecting the water supply and heating system to a double-circuit boiler.
The presence of two heating circuits at once also affected the number of connected pipes. In contrast to the single-circuit one, where there were only three pipes, supplying and discharging water and one supplying gas. There are five such pipes in a double-circuit boiler. The diagram depicting a double-circuit gas boiler shows the following (from right to left):
- pipe with incoming coolant for heating;
- supply pipe for hot water supply;
- gas supply pipe;
- pipe with outgoing hot water for water supply;
- pipe with outgoing coolant for heating.
Important! Before using the above diagram when connecting your own boiler, carefully study the manual for it. It is quite possible that your boiler will be connected slightly differently. For example, both inlet pipes are on the right side, and both outgoing pipes are on the left.
It is also worth noting that today on the market you can find a double-circuit gas boiler, both wall-mounted and floor-standing. In addition to the installation method, the difference between them is that floor-mounted requires mandatory separate room- boiler room, while the wall-mounted one can be installed in the kitchen or in a place reserved for the boiler. Where exactly and how to install gas heating boilers we'll look at it next.
Standards and requirements for the installation of gas boilers
It should be noted right away that the installation and connection of a double-circuit gas boiler can only be carried out by specialized organizations that have permission and a license for this activity. Self-installation and connection is fraught with rather high fines. But still certain work You will have to do it yourself to prepare for connecting the boiler and obtain the necessary permits.
The following recommendations and rules are excerpts from the main regulatory documents, such as SNiP 42-01-2002 “Gas distribution systems”, as well as SNiP II-35-76 “Boiler installations”, Code of Design Rules autonomous systems heating supply SP-41-104-2000. In these regulatory documents describes in detail what can and cannot be done when installing gas equipment. We will consider the main most important requirements for installation of gas boilers.
1. The room where the gas boiler will be installed must be at least 4 m2 with ceilings not lower than 2.5 m;
2. The doorway in the room must be at least 80 cm wide;
3. The room must have a window opening. The size of the window is calculated based on the following requirements - for 10 m2 of area, a window with an area of 0.3 m2;
4. It is necessary to have high-quality ventilation in the room to ensure constant gas combustion. The hole area should be 8 cm2 per 1 kW of boiler power. This also applies to boilers with a closed combustion chamber, for which coaxial chimneys are used, combining the functions of removing combustion products and supplying air to the boiler;
5. The diameter of the chimney is selected according to the power of the boiler itself and is calculated using a special formula. In general, boilers from 30 kW to 40 kW are most often used for heating a house. Accordingly, chimneys with a diameter of 130 mm and 170 mm are installed;
6. The upper end of the chimney should protrude 50 cm above the roof ridge. If used coaxial chimney, then its outlet end should protrude from the air intake by at least 20 cm;
7. The gas pipeline in the house must be made of metal pipes. But to connect the boiler to the main line, you can use flexible corrugated pipes;
8. The boiler must be equipped with a special automatic current and thermal protection;
9. The room with the boiler must be equipped with a gas analyzer;
10. Installation of gas boilers in basements permitted only for private homes. For apartment buildings installation of gas boilers is permitted only in the kitchen or in specially designated boiler rooms;
11. Each boiler must be equipped with a gas meter;
12. The room must have a cold water pipeline;
13. In the room where the boiler will be installed, the walls must be leveled and plastered;
14. Boilers cannot be installed on combustible surfaces, in corridors, in the bathroom, in a dormitory, on a balcony, in rooms without windows or vents, in the basements of apartment buildings;
15. The boiler must be placed at least 15 cm from the wall. There should be a minimum of 20 cm from the top edge of the chimney to the ceiling. The outer part of the chimney should protrude 30 cm from the wall of the house. The installation height of a wall-mounted boiler should be 0.8 - 1 m from the floor, and a heat-insulating panel should be placed between the wall and the boiler.
Important! If the boiler is a double-circuit boiler with a closed combustion chamber, then the presence of windows in the room is not necessary.
By observing these simple rules You can easily obtain permission to install a double-circuit boiler at home. Of course, a more detailed familiarization with SNiP will not be superfluous, since the above rules are general and certain restrictions are possible for each specific case.
Coordination of installation with authorities
When installing double-circuit boilers, compliance with SNiPs is only a small part of the hassle that you have to face. The most time will be required to obtain the necessary permits and approval of installation. To obtain permission you must do the following:
1. To connect a private house or an apartment to the city gas supply, you must obtain technical conditions for connection. To do this, we write an application to the city gas service. The application must indicate the estimated volume of gas consumed per hour. It will take 1 to 2 weeks for your application to be processed. After which you will be given technical installation specifications.
2. Having received the technical conditions, it is necessary to develop a gas supply project. In essence, this is a diagram of boiler installation, gas pipeline laying and connection points. In a private house, this also includes a diagram for laying gas communications around the site. The project is developed in a specialized bureau by design engineers with a license for the design of gas communications. Contacts of companies performing design can be easily found in Gorgaz.
3. After creating and finalizing the project, it is sent to Gorgaz or another competent service (Raigaz, Oblgaz, Mingaz). Project approval may take from 1 week to 3 months. The approval period depends on the complexity of the project itself. Along with the project, it is also necessary to submit a number of related documents:
- boiler technical certificate;
- instructions for its use;
- certificate of compliance with technical and sanitary requirements;
- conclusions of the examination on the boiler’s compliance with all necessary requirements.
These documents are included with the boiler from the manufacturer, so it is important to check their availability when purchasing the boiler.
Of course, it is possible to reject the project. In this case, you should receive an official document with the refusal and reasons for the refusal, as well as a list of changes for the project. After making changes and resubmitting for approval, you will receive permission to install the boiler.
Installation of a double-circuit gas boiler
Having decided on the installation location of the double-circuit gas boiler, as well as connecting all communications from the hot water supply (hot water supply) and heating to it, you can begin installing the boiler itself. It is necessary to immediately make a reservation that, regardless of whether it is a wall-mounted or floor-standing boiler, the same materials and components will be required for its installation and piping. Below is a general list of what is required for reliable operation:
- Ball Valves;
- filter rough cleaning;
- magnetic filter;
- mesh filter;
- gas filter;
- sweeps;
- flexible corrugated hose;
- pressure gauge;
- thermostat;
- coaxial chimney;
- safety valve 3 bar.
Important! Quantity and equipment related materials depends on the connection diagram of the gas boiler.
A double-circuit wall-mounted gas boiler can be installed in almost any room permitted for it. You can install it yourself, but the direct connection of gas equipment is carried out by a specialist who has the appropriate certificate to perform this type of work. Self-connection boiler will entail fines.
Connecting a double-circuit gas boiler begins with preparing the site for its installation. First of all, this concerns the supply of pipes for hot water and heating, as well as preparing the opening for the chimney and lining the wall with fireproof material. As soon as everything is ready, we begin installation of the boiler:
1. The first step is to flush the boiler pipe system to remove any dirt particles from the system that may have entered during the boiler assembly at the factory. Then we put the previously removed plugs on them.
2. The wall-mounted boiler is mounted on special strips that are included in the kit. The installation height of a wall-mounted boiler should be 0.8 - 1 m from the floor. We drill holes in the wall for the planks and secure them to the wall with self-tapping screws. For reliability, anchors can be used instead of self-tapping screws.
Important! It is necessary to monitor the horizon of the installed slats. Depends on correct placement the boiler itself. The slightest misalignment can lead to rapid failure of the boiler heating system.
3. Install the boiler on the mounting strips. Let's check how level it is. If necessary, we correct and fix it.
4. We find the incoming pipes and first attach ball valves to them, and then filters for coarse or fine cleaning water. This will allow, if necessary, to shut off the entire system for washing and cleaning the filters.
6. The next step is to install the squeegees. They are the ones that will connect the boiler with pipes from the hot water supply to the heating.
Important! We do not touch the gas supply pipe of the boiler. The installation of the meter, valves, as well as its connection and pressure testing will be carried out by a specialist from the gas company who has permission to carry out this type of work.
7. Let's move on to connection heating system. If you are connecting the boiler to an old system, you must first rinse it several times to remove scale and salts from it.
8. We connect the squeegee to the heating pipe connected to the boiler. If necessary, a circulation pump can be installed between the outlet and the pipe.
Important! We make sure that the arrows on the taps, drains and filters point in the direction of movement of water from the system to the boiler.
8. We complete the heating connection procedure by connecting the outgoing pipe from the boiler to the heating system. At the same time, we make sure that the direction of water movement on the fittings corresponds to the real one.
9. Connect the hot water supply. All work is essentially identical to connecting the heating, with the difference that instead of a coarse filter, a fine filter or magnetic filter is installed.
10. Attach the chimney to the boiler. To do this, a chimney pipe is inserted into the previously prepared hole and then connected through an elbow to the chimney fitting in the boiler itself.
Important! If you bought a boiler with an open combustion chamber, then the chimney pipe must meet the following conditions:
- the pipe must be made of metal resistant to acidic environments;
- the chimney is installed above the ridge of the house;
- a cleaning hatch must be installed in the chimney itself;
- the chimney itself should consist of no more than three elbows;
- parts of the chimney from the boiler to the exit to the street should not exceed 25 cm.
A double-circuit floor-standing gas boiler is also installed in the manner described. The key difference in installing a floor-standing boiler is the allocation of a special room for the boiler, where fire protection is installed on the floor and walls. In addition, the boiler itself is not attached to the wall with brackets, but is most often fixed to the floor.
Upon completion of the installation of the double-circuit boiler, all that remains is to wait until it is connected to the gas pipe and put into operation. This stage of boiler installation is carried out by a specialist from the gas company. It should be noted that if you have never performed this type of work before, it would be better to seek help from the experts. Of course, all the work will cost a pretty penny, but the safety and reliability of the connected boiler will also be much higher.
The task is not easy. The boiler cannot be hung haphazardly, since the safety of the people living in the house often depends on how correctly the wall-mounted boiler is installed.
This means that the installation of this device is carried out in strict accordance with technical requirements and standards adopted in Russia at the legislative level.
That is why installing a wall-mounted boiler with your own hands is an extremely labor-intensive and difficult process for a beginner.
Stages of preparation for boiler installation
Before the owner of the house starts, you will need to collect some documents:
- agreement on supplying the house with gas;
- technical specifications and installation diagram of the gas system, approved by the relevant authorities;
- written permission from the gas inspector to install the equipment.
Boiler installation rules and regulations
Gas heating equipment is installed in accordance with developed and approved technologies that ensure the safety of its operation.
- The question of how to install a wall-mounted boiler begins with preparing the room for it. The room must meet certain requirements: the boiler room can be located anywhere in the house, except the bathroom, living rooms and a bathroom. However, when installing wall units, this requirement may be relaxed depending on the type of boiler. The volume of the room is from four square meters, the ceiling height is from two meters. The width of the doorway is at least 800 mm. The room should also have daylight boiler through the window. In this case, the window size must correspond to 0.3 square meters. for every 10 sq.m. premises.
- The rules for installing a wall-mounted gas boiler regulate the supply of a certain volume fresh air using fresh air ventilation to the place where the boiler is used. An insufficient amount of incoming air may be due to the accumulation of a substance hazardous to health and life in the room.
- : the standards for its placement are such that there must be more than 10 cm from the wall to the surface of the boiler. If this distance is less than required, the wall must be protected with a fire-resistant coating.
- Gas pipes can be metal, but not plastic.
- The chimney opening must correspond to the power capabilities of the boiler. In this case, its height must be at least 5 m, provided that the chimney is installed above the ridge on the roof of the house. When installing a chimney, it can have no more than three bends.
- When organizing a power supply system, it is necessary to provide a circuit breaker with current protection and thermal protection.
- In the room where the boiler will be located, there must be a gas sensor connected to a relay. In the event of a gas leak, the sensor must send a relay signal to block gas flow. In addition, an audible alarm should sound.
- Installation of a wall-mounted gas boiler; when starting it up, regulations require that the device be provided with a gas meter.
- If there are others near the boiler gas appliances, then the distance between the devices is set at at least 20 centimeters.
- When installing, the requirements even affect the completeness of the equipment. The boiler package must comply with the standards and contain: a manual, fasteners, a paper template for installation, special keys and fasteners.
- The installation height of the wall-mounted boiler is 80 cm - 160 cm from the floor surface.
If all these requirements are met, then there is no doubt about the reliability and fire safety of the system. gas heating. Please keep in mind that the heating system must be checked regularly Maintenance by employees of the city gas service.
