Should the boiler hang level? What should be the room for a gas boiler: requirements and rules

Fire safety standards

In order for a gas heating system to comply with fire safety standards, certain conditions must be met:

1. Atmospheric devices can be located in the attic, basement or any other floor of the house. It is prohibited to place these units in the basement.
2. Turbocharged gas boilers are allowed to be installed in any non-residential premises, as well as in the attic and basement.
3. Doors to rooms containing gas appliances must open outward.
4. The boiler room is finished with fireproof materials with a minimum fire resistance limit - no less than EI45.
5. Turbocharged mounted gas boilers are fenced off from the adjoining wall with a shield made of non-flammable material. Floor-standing models are placed on a fire-resistant lining.

Flammable interior elements may be installed next to the boiler no closer than 30 cm.

Energy supply rules

The energy supply of a gas boiler includes the following conditions:

1. Mandatory grounding of the unit - this eliminates the possibility that a spark of static electricity will cause a fire.
2. It is recommended to connect volatile devices to a voltage stabilizer and an uninterruptible power supply. Otherwise, if the power goes out, the owners will be left not only without light, but also without heating.
3. The socket for the gas boiler must be located close to it so that it is possible to connect the device directly. Carrying bags are not permitted.

Requirements for the chimney device

The rules for installing a gas boiler in a private house are supplemented by the rules for installing a chimney if the unit has an open combustion chamber. The following requirements apply to the chimney installation:

1. The pipe cannot have more than 3 turns.
2. The section connecting the boiler pipe and the chimney has a length of no more than 25 cm.
3. The diameter of the pipe must correspond to the power of the unit.
4. The edge of the chimney is placed at least 50 cm above the ridge of the roof.
5. The hole for the pipe to pass through the ceiling is made larger than the diameter of the chimney. Fire-resistant material is placed between it and the ceiling material.
6. To ensure the collection of condensate and soot during cleaning, a condensate collector should be provided at the bottom of the pipe.

When installing a gas boiler with your own hands, it is important to comply with all the requirements for the placement of a specific model of the unit. Otherwise, the gas supply company will not give permission to operate incorrectly installed equipment.

It is well known that natural gas is the most economical source of energy for heating a home. Therefore, the desire of owners of country houses to connect to gas seems completely natural. However, we must not forget that gas is the riskiest type of fuel in terms of explosion and fire safety. That is why the installation of a gas boiler in a house is carried out taking into account numerous rules and regulations that are imposed by supervisory authorities.

First of all, we note that the standards for the installation of gas boilers in a residential building are determined by several documents. The main ones are two sections of Construction Norms and Rules (SNIP) - II-35-76 and 42-02-2002. They contain requirements for the room in which the gas boiler is supposed to be used, as well as for the place where the gas line is inserted into it. The need for gas heating may arise for owners of different types of real estate:

According to current legislation, self-installation of gas equipment is prohibited. Installation, configuration and connection of heating boilers can only be carried out by authorized organizations that have the necessary certificates and licenses.

In what rooms is installation allowed?

You cannot choose the installation location of the gas boiler in the house yourself. It is approved during the approval of the heating system project along with the type of boiler, communications layout and location of the gas pipe entry point into the room. Permission to connect a boiler may not be obtained for all types of premises. Let's look at the main options in more detail.

Bathroom

The most controversial place for a gas boiler is the bathroom. Many owners of apartments and houses want to place a heating unit there due to lack of space in other rooms. However, gas workers almost always refuse such requests. Let's try to figure out why:

• SNIP 2-04-87 contains an explicit ban on installing a boiler in the bathroom. However, this section was declared obsolete in 2002 and replaced by SNIP 42-01-2002, which no longer contains such a norm. However, gas companies take advantage of this uncertainty and refer to earlier requirements;
• One of the requirements for the boiler room is the presence of a window facing the street. Most bathrooms don't have it, so they don't meet this particular parameter. However, theoretically, this drawback can be circumvented;
• The same applies to the width of the door - it must be at least 80 cm;
• Another limitation that may interfere with the approval of installation in the bathroom is the presence of high humidity and dampness. Indeed, the electronics that a modern gas boiler is literally crammed with can theoretically fail. But, on the other hand, the body of any boiler is absolutely sealed, and control boards are often specially treated with special protective films in order to protect them from moisture. So this is also not a 100% reason to refuse installation, especially since there are no explicit restrictions on humidity in any of the regulatory documents.

However, practice shows that almost no one can obtain permission to install boilers in the bathroom. The only possible option is if you are replacing an old gas water heater and carrying out this as if you were reconstructing the heating system in a house.

Living spaces

Everything is much simpler here. SNIP 2.04.08-87 clearly allows the installation of boilers and water heaters only in kitchens and non-residential premises that meet certain requirements. We will present these requirements a little later, but for now we will simply note that it will not be possible to install a gas boiler, for example, in a bedroom or living room - gas specialists will never approve such a project.

Other premises

In the vast majority of cases, installing a heating system in a house or apartment requires the installation of a gas boiler with a capacity of up to 60 kW. Such a boiler can be placed in the kitchen or in any other place - there is only one requirement for the room - it must be non-residential and impenetrable.

For boilers of higher power, more serious restrictions are put forward:

• Up to 150 kW – a separate room on the floor, including the basement;
• Up to 300 kW - a separate room on the ground, ground or basement floor, as well as in an extension to the house.

The following table shows the design requirements for installing boilers of various capacities.

If you install a gas boiler in a room whose walls and floor are made of flammable materials, they must be protected using a separate fireproof structure with a thickness of at least 3 mm.

In a private house, a metal sheet laid over a layer of asbestos is perfect.

Stages prior to boiler installation

In accordance with the Housing Code of the Russian Federation, any change in the heating system refers to the redevelopment of the premises, which must be agreed with representatives of local authorities.

The project will necessarily reflect all the requirements for installing boilers, which we presented in this article. Therefore, if your system is installed in full accordance with the project, handing it over to gas workers will not be difficult. Let us remind you once again that the installation of gas equipment should only be carried out by authorized specialists.

You have purchased a new gas boiler for your private home and it’s time to take its place in the furnace room. To do this, you can hire a specialized company or contact the appropriate service. But the cost of installation in this case will significantly hit your wallet, while there is an opportunity to reduce the cost of the process. Yes, some operations can only be performed by licensed organizations, but this is only half the work; the rest can be handled independently. Here we will talk about how to install a gas boiler in a private house from start to finish.

Where to begin?

Since the installation of new gas-using equipment requires compliance with certain rules, it is worth ordering all work that requires a license from the gas service:

• Issuance of technical specifications.
• Development of project documentation.
• Work on connecting to the natural gas pipeline.

You can complete the rest of the steps yourself. First, you need to obtain technical conditions for installing gas equipment from the gas service. Check them out or make a copy and immediately order project documentation from them. When it is ready, it will need to be approved by the gas service. As you might guess, this procedure is a pure formality; after its completion, a team will come to your home and install the gas boiler in terms of its connection to the fuel line, about which a corresponding report will be drawn up.

All that remains for you to do is to complete the piping and connection to the heating system and laying electrical networks. Here you will have the opportunity to save money, either by doing everything yourself or with the help of familiar plumbers. The last stage is the final paperwork.

This is just a brief description of one of the possible algorithms for solving the problem, but in fact, not everything is so simple, because gas boilers must be installed in compliance with regulatory requirements, and it would not hurt to become familiar with them at the stage of choosing a heat generator.

Requirements for boiler installation

First of all, it is necessary to take into account all the requirements for the room where the heat source is supposed to be placed. The options are:

• kitchen;
• a room inside the house, adjacent to one of the external walls and having windows;
• premises in the basement or basement;
• in the outer annex.

In the kitchen, installation standards allow the installation of a floor-mounted or wall-mounted unit with a heating capacity of up to 60 kW. Equipment with ratings from 60 to 150 kW can be installed in a separate room on any floor, and from 150 to 350 kW - only on the first or ground floor, in the basement or annex. At the same time, it is important to observe the dimensions of a separate room or an attached part; they cannot be smaller than specified in the standards. The minimum standard height of such a room is 2.5 m for any power within the specified limits.

Note. The thermal power values ​​specified in the standards and affecting the installation conditions of the boiler are the total power of all units in the boiler room, including those working for the needs of domestic hot water.

For heat generators with a capacity of up to 150 kW, in accordance with the standards, the smallest volume of the room for installing a gas boiler is 15 m3, in addition, for each kW of water heating equipment, 0.2 m3 is added to this volume. If the total indicator of all units exceeds 150 kW, then the dimensions of the room are not standardized. But there are rules for the installation and safe operation of boilers, according to which it is necessary to maintain technological gaps between the units and the walls of the room; they are adopted for reasons of ease of maintenance and access to all systems in the boiler room. The dimensions of the passages in accordance with the rules are as follows:

• From the protruding part of the gas burner device to the wall on the front side of the heat generator - at least 1 m.
• If the operating instructions for the unit say that it needs to be serviced from the side or rear, then you will have to maintain a passage width of 1.5 m, but when there is no such entry, but you need to provide access to other equipment or fittings, then it is enough to make the clearance 700 mm. In other cases, installation requirements are stated in the product documents from the manufacturer.
• If you plan to install 2 heat sources in the furnace room, then you should not place them opposite each other, since you will have to provide a clearance of at least 2 m between the protruding parts of the burners.
• Nothing should be laid through passages at a height lower than 2 m.

For a kitchen where it is allowed to place not very powerful heating equipment (up to 60 kW), there are not the most stringent requirements for the installation of gas boilers. You just need to comply with the volume standard given above, and also ensure air exchange in the amount of 3 times in 1 hour. Additionally, it is necessary to supply supply air for fuel combustion; its consumption for each unit is indicated in the technical specifications. This standard applies to all types of boiler houses.

Note. For heat generators with a closed chamber, the installation standards for gas boilers do not force the supply of an air mixture for combustion, since they take air directly from the street through a coaxial chimney, which will be discussed below.

The regulatory documents propose organizing ventilation for the boiler in the kitchen using an exhaust shaft and a supply grille built into the front door. The flow area of ​​this grid is also standardized; its area cannot be less than 0.025 m2. In the same way, you can arrange air exchange in individual combustion chambers. Difficulties with supplying fresh air may arise in basements or basement floors; it is possible that a special supply fan will need to be installed to meet the technical conditions.

In boiler rooms located on the first, ground floor or in an extension, window openings with a glazing area of ​​at least 0.03 m2 are needed for each cubic meter of room volume. The attached premises also have requirements for fire resistance of walls, a separate foundation and entrance doors. In addition, the extension cannot be built on the front facade of the building, and during construction it is necessary to retreat 1 m horizontally from the nearest window or door.

It should be noted that the requirements for a gas boiler located in a wooden house are identical to the standards for buildings made of other materials, that is, the rules for installing boiler rooms are the same for all buildings.

Installation work for boiler installation

When a suitable room has been selected and design documentation has been completed for it, you can begin to manually install the heat generator in place. To do this, you will need a connection diagram for a gas boiler in a private house, which must be present in the project. It shows the installation location, the distance to all enclosing structures and the technical requirements for the work.

Often, the installation of floor-standing gas boilers requires the construction of a foundation. In many cases it is not needed, for example, when the room has a high-quality screed and the weight of the unit does not exceed 50 kg. If the weight of the equipment is greater than this value, then you will have to prepare the foundation. To do this, you need to destroy the existing screed, pour a cushion of crushed stone and compact it thoroughly. Then tie a mesh of periodic profile reinforcement with a diameter of 8 to 12 mm, lay it on the finished base and fill it with concrete.

In order to withstand the technology of installing gas boilers, the dimensions of the foundation in plan should be 50 mm larger than the dimensions of the equipment, and in height it should protrude 50-100 mm above the level of the screed. Complete hardening of the concrete slab will take you at least 2 weeks; this must be taken into account when planning the work.

Next, a fireproof asbestos or metal gasket is placed on top of the foundation and a heat generator is placed on it, adjusting the legs of the unit so as to maintain a clear horizontal line. After this, using the gas boiler installation diagram, it is connected to all utility networks, except the fuel line. This connection, as mentioned above, is carried out by a licensed organization.

To install a wall-mounted gas boiler in a private house, you do not need a foundation, but a solid foundation in the form of an outer wall that can support the weight of the unit. First of all, markings are made on it, showing where the heat generator itself will be suspended and where the chimney pipe will exit. Then, using a hammer drill, a through hole is drilled in this place, into which a metal sleeve is inserted.

There is no particular difficulty in hanging a wall-mounted gas boiler. If the action takes place in the kitchen of an apartment or house, it is necessary to take measures to protect the furniture from debris and then begin the fastening process. Difficulties may arise when installing heavy units, whose power reaches 120 kW; here you cannot do without an assistant.

Note. When a wall-hung boiler is attached to a wall made of flammable material, a special bracket must be made to allow a clearance of 45 mm between the wall surface and the rear panel of the heater. Also, a sheet of non-flammable material should be attached to the wall, acting as a protective screen.

The last thing to do is piping the gas boiler and installing the chimney. Here it is necessary to compactly place taps and other fittings under the body of the heat generator so that everything looks neat and at the same time it is possible to disassemble or change any element. Therefore, when the heating circuit in a house is made of polypropylene pipes, it is better to use bronze taps and a mud pan, and connect plastic pipes through threaded adapters. In this regard, it is somewhat more difficult to install a double-circuit gas boiler, where you will need to lay pipes for hot water supply and correctly connect them to the appropriate pipes.

Requirements for chimneys

In essence, the requirements for the chimneys of floor-standing and wall-mounted gas boilers are identical; the difference may be in the design of the flue itself. It depends on the design of the heat source:

• Heat generators with an open combustion chamber take air from the room and exhaust combustion products through a traditional chimney with natural draft.
• Units equipped with a closed chamber draw in air from the street forcibly using a fan through a double-walled pipe, which also serves as a flue (coaxial chimney).

A traditional chimney for a gas boiler is installed in the thickness of the wall or suspended from the outside of the building. The cross-section of the outlet pipe from the unit determines the diameter of the entire chimney; it should be the same size, or better yet, 20-50 mm larger. The horizontal section connecting the boiler to the chimney is ideally 1 m long, the maximum allowable length is 2 m.

Below the insertion point, a door is required for cleaning and internal inspection, and the blind end of the vertical pipe is equipped with a condensate drain system. When installing the chimney of a gas boiler, you must remember that it is not allowed to cover the pipe outlet with umbrellas, deflectors, weather vanes, and so on. In accordance with the regulations, only a narrowing nozzle can be installed.

Unlike traditional exhaust ducts for combustion products, it is much easier to install a double-walled chimney for heat generators with a closed chamber. Having made a hole of the required diameter in the outer wall and built a metal sleeve into it, a coaxial chimney is installed, which is a horizontal double-walled pipe of a certain length. The only condition that must be met is a slight slope towards the smoke exit. This is done to prevent condensate formed in the air duct from flowing into the boiler.

Conclusion

So, installing and piping the boiler with your own hands is not an easy task, but it is quite feasible. It will take a lot of time and patience to complete all the documentation, but the installation work itself will take a maximum of 3-4 days, or even less. It is important to prepare well and purchase in advance all the missing elements of the strapping scheme, as well as fasteners.

Today, gas boilers and water heaters are used everywhere both for heating water and for heating houses. For the most part, separate single-circuit boilers or one single-circuit boiler and an indirect heating boiler are used for heating and hot water supply, 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 boiler, where a gas burner heats a heat exchanger with a 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 of a double-circuit boiler looks like an ordinary 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. At the same time, one more very important point should be noted. 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 the floor-mounted one requires a separate room - a boiler room, while the wall-mounted one can be installed in the kitchen or in a place reserved for the boiler. We will look further at where and how to install gas heating boilers.

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 fairly high fines. But still, you will have to do some work on preparing to connect the boiler and obtaining the necessary permits yourself.

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 rules for the design of autonomous heat supply systems SP-41-104 -2000. These regulatory documents describe in detail what can and cannot be done when installing gas equipment. We will consider the main most important requirements for installing 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 window size 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 a coaxial chimney is used, 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 is permitted only for private houses. 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-hung 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 following these simple rules, you can easily obtain permission to install a double-circuit boiler at home. Of course, it would not be amiss to become more familiar with SNiP, 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 apartment to the city gas supply, you must obtain technical conditions for the 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 for installing a boiler, laying a gas pipeline 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;
• coarse filter;
• magnetic filter;
• mesh filter;
• gas filter;
• sweeps;
• flexible corrugated hose;
• pressure gauge;
• thermostat;
• coaxial chimney;
• safety valve 3 bar.

Important! The quantity and configuration of 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. Connecting the boiler yourself 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. The correct placement of the boiler itself depends on this. 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 water purification. 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 connecting the 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.

Nowadays gas is one of the most common types of space heating. Therefore, many are interested in what is needed in order to install gas equipment in their house or apartment. What are the room requirements for installing a gas boiler? Requirements for equipment and places of its installation are clearly regulated by SanPin standards. Controlling organizations monitor their implementation, because the place equipped for a boiler room is explosive. Therefore, you should strictly follow the standards.

Gas boiler in a private house - main types

• Floor-standing. They are very common. Installation of such equipment should be carried out in specially equipped places with good ventilation. Suitable for heating large areas.
• Wall-mounted. Such units take up very little space and are used for heating small places.

Installation Requirements

First you need consent to install gas equipment. To do this, you need to contact GorGaz, write an application and provide the following documents:

• a project that includes a connection scheme to the central city highway;
• technical passport of the selected unit;
• instructions for use;
• conclusion of the expert commission on the suitability of the equipment.

NOTE! For an installation with a power of less than 30 kW, the boiler room area is at least 7 m2 . If the power is up to 60 kW, it is equal to 13 m2. Over 60 kW – 15 m2 and more.

Requirements for a gas boiler room in the basement

Previously, it was prohibited to install boiler rooms in basements. However, recently this has become possible thanks to the transition to propane, which is in a gaseous state. Now it is allowed to install a gas boiler in the basement. Only the power of the equipment is limited; it should not exceed 200 kW. You just need to comply with all the requirements assigned by Sanpin.

As a rule, equipping a boiler room in a private house does not cause difficulties. All the necessary requirements are quite easy to fulfill. You only need to build a boiler room that meets all prescribed standards.

Installation in an apartment poses a number of difficulties. The most suitable place for this is the kitchen. To install a gas boiler in it, you need to meet certain requirements. This:
