Where to install a gas boiler in a private house. Installing a gas boiler in a private house - what standards do you need to know about? Installation room

After gas supply to a private home, the next task, as a rule, is the installation of gas equipment.

Many apartment owners also refuse central heating and prefer the autonomous option, wanting to save money and turn on and off the heating of the premises when they see fit. But in order for such heating to be safe and efficient, it is necessary to comply with the requirements for installing a gas boiler.

The gas supply control organizations prepare and approve the necessary documents and By for connecting the gas main to the house, and for installing heating units.

One of the rather unpleasant procedures when installing a heating boiler that runs on gas is the collection and execution of a voluminous package of documents. Many, faced with this process, soon rush to abandon this idea.

Basic requirements and standards can be found in the document “Gas distribution systems”, included in SNiP 42-01-2002. In addition, it would be nice to study a document that is no longer working, but contains a large amount of information that will also be useful - this is “Gas supply” SNiP 2.04. 08—87. Additionally, you will have to familiarize yourself with the standards given in related documents that talk about boiler systems, ventilation systems, heating, sewerage, water supply, construction safety, sound insulation, fire safety, etc.

Coordination of boiler installation

You need to go through several authorities to obtain approval for the installation of a gas-fired boiler. On your own, without approval, the installation process will be illegal and unsafe, and not only for the home owner, but also for the rest of the residents of the house, if the boiler is installed in a high-rise building.

1. Technical conditions

To connect to the gas supply of a private house or apartment have to obtain from the gas supply organization technical conditions permitting this procedure. To do this, a statement is written to the controlling organization. It must indicate the approximate demand for gas volume per hour. The registration procedure lasts seven - fourteen days. Upon successful completion of this event, a document will be issued - technical conditions for the installation of equipment operating on gas fuel. This is a permit for preparatory construction and installation work.

2. Project

Having the technical specifications in hand, you can proceed to the second step - development project documentation. The gas supply project includes plans for laying a gas supply pipe from the boiler installation site to the central gas pipeline.

The project will also indicate sections of the gas pipeline crossing the site

If the home is located in the private sector, and the pipeline must cross the land, then a diagram of the gas pipe on the site is also drawn up, indicating the location of its entry into the wall of the house. The project is developed by engineers licensed for such activities, based on the provisions of the GOS.

3. Coordination with the gas supply organization

The completed project is submitted for approval to the organization that controls gas supply in the applicant’s area of residence. Project approval takes from seven to one hundred days, depending on the volume and complexity of the document. The following materials regarding the heating device are attached to the project:

examination of the boiler’s compliance with all requirements necessary to ensure normal operation and safety;
technical data sheet of the device;
certificates of compliance with technical and sanitary-hygienic requirements;
operating instructions.

All documents specified in the list are prepared by the manufacturer and must necessarily accompany any product of this type. They are transferred by the seller to the buyer at at When purchasing a device, you should pay special attention to this.

If the project was rejected for the first time, the applicant is given a document indicating the reasons for the refusal and a list detailing all the problems of the project that require correction.

If the project is approved, it is certified by the signature and seal of the responsible person. This document is the final permission to install the heating device.

Installation restrictions

For safety reasons, appliances operating on gas fuel are prohibited from being installed in the following premises:

in which there are no ventilation systems;
in dormitories (rooms);
in bathrooms;
in the corridors and on the balcony;
in basements;
on the ground floor;
on flammable wall surfaces.

One important clarification regarding installation on the ground floor and basement: installation is only permissible in a private single-apartment house, i.e. if the house is not divided into several owners.

Requirements for installation of units

When installing a gas boiler, the homeowner must strictly adhere to a number of regulatory rules:

the boiler is installed in such a way that there is free access to it from any side;
the size of the entrance door to the boiler room where the device is installed cannot be less than 80 centimeters wide;
the area of the boiler room or other room cannot be less than four square meters;
the boiler room must have a window with an area of at least 30 cm² per 10 m³ of volume - to provide lighting in any situation;
the ceiling in this room must have a height of at least two and a half meters;
water must be supplied to the boiler room;
a grounding loop is mandatory if the operation of the boiler is related to the consumption of electricity;
boiler room walls must be plastered;
the chimney must have a cross-section corresponding to the power of the unit.

Having considered the requirements presented, we can conclude that a kitchen can be a fairly good room for installing a wall-mounted boiler, if it is not possible to install a boiler room. There it can be placed next to the gas stove.

An additional advantage of installing a boiler in the kitchen is that it meets all the above requirements - ventilation, gas supply, adequate room area, cold water supply. In addition, by installing a boiler there, you can save a lot on pipes and keep more than one wall intact.

Floor-standing boiler, which has massive dimensions and a power of 150 kW, must be installed in a separate room - the boiler room. It should be taken into account that a device with a power of up to 60 kW can be installed in a room with a volume of at least 27 m³, which means it can be installed in the kitchen.

But you need to know that floor-standing boilers are quite noisy, so if you plan to install the unit in an apartment, it is better to choose a wall-mounted option.

If the boiler is hung or installed against a wall made of flammable material, it must be protected with a heat-resistant insulator, for example, special plasterboard or asbestos sheet will do.

Boiler installation

Installation of any gas equipment is carried out by a gas technician; independent installation is strictly prohibited. The manufacturer attaches the boiler installation diagram to the documentation of the heating device, and it will be useful to the installer.

When installing the unit in a boiler room, you need to arrange the floors correctly. They must be made of non-flammable material and have a water drain. It is necessary to extract coolant from the heating circuit in case of an emergency.
Installation of gas equipment is not carried out at sub-zero temperatures; it must be at least five degrees Celsius. But it is also unsafe to install equipment at too high a temperature, so it should not exceed 35 degrees.
A level mark is made on the wall for the bracket, on which the boiler will then be hung.
If a dual-circuit gas appliance is installed, then a strainer is placed on the return pipe. It is necessary to ensure that the heat exchanger remains clean for a long time. Ball valves are installed on both sides of the filter and on the boiler pipes.
When connecting the boiler to the gas supply line, a gas meter, a special gas tap, a gas alarm and a thermal shut-off valve are installed in front of it.
The socket into which the boiler will be connected, if it is volatile, must be grounded.
When the boiler pipes are connected to the water supply and gas supply, the system must be filled with water. This is done slowly so that the air in the future coolant does not stagnate - it will have the opportunity to leave the circuit along air vent devices. During the period of filling the system, the boiler must be disconnected from the power supply.
Before starting the boiler, be sure to check the gas pipe connections for gas leaks. This is very simple to do - you need to knock off a thick foam from any detergent and apply it to the connecting elements using a sponge. If there is a leak, then a soap bubble will certainly inflate, and if the pipe is connected tightly, the foam will gradually settle. Only after all these manipulations can you start the system by connecting it to the power supply.

Ventilation

It is very important to ensure that the room where the gas appliance is installed has good ventilation.

Supply and exhaust ventilation is a prerequisite for any boiler room

The kitchen area in a multi-storey building is equipped with a common building ventilation system, so there will be no problems with it. When installing the device in a boiler room, a ventilation duct is installed in the ceiling of the room and vented outside.
Supply ventilation can be installed in the door by making a hole and installing a ventilation grill.
Special standards have been defined for ventilation inlets. So, for one kW of device power, the grille must have a size of no less than 8-10 cm² (air intake from outside the house) and no less than 30 square meters. cm (air intake from inside - from other rooms).

Chimney

Particular attention to the correct organization of the chimney

Correct installation of the chimney is no less important than the ventilation system. The chimney can be made of a metal sandwich pipe that is discharged through the roof of the boiler room (or through the wall) and rises along the wall from the outside to the roof.

Or maybe coaxial, coming out through the wall and having a small size. Each of them is established according to certain rules.

Combustion products should not enter the room, which means that the smoke exhaust duct must be gas-tight.
The diameter of the chimney should not be less than the diameter of the pipe leaving the boiler. The ratios for boiler power have been established - the homeowner will definitely be familiarized with these figures when drawing up project documentation.
The head of the metal pipe must rise above the roof no lower than its ridge - this will ensure normal removal of gas combustion products and prevent backdraft.
When the chimney is brought out through the wall, a hole is made for it, the pipe is connected to the boiler and taken out into the street. If gaps have formed in the opening between the wall and the chimney, they must be sealed hermetically. This coaxial type flue duct is suitable for a boiler with low or medium power, and is usually used for wall-mounted models.

Requirements for premises with gas equipment

Where to install a gas boiler

Selection of boiler and installation standards

Before purchasing a boiler, you need to familiarize yourself with all the nuances of its installation and approval of permits and design and installation documentation. Only by reliably knowing all these rules for gas wall-mounted and floor-standing boilers will it be possible to accurately determine which one is suitable for a particular apartment or house.

Installing a gas boiler in a private house requires solving some problems. To the premises and equipment there are specific requirements, which will have to be carried out strictly, because Not only the quality of operation, but also safety depends on this.

Preparation for installation of a gas boiler room in a private house includes important steps in its design and approval of installation in the relevant organizations. At this stage, it is selected or built room to place the boiler, and also select required type of equipment.

It is important to correctly estimate the required gas consumption. This fuel is quite accessible in many regions of the country, but its additional selection from a centralized network must require permits.

An important preparatory step is choosing the type of equipment. Gas boilers have 2 main types:

Single circuit type. It is intended only for heating and has a simpler design.
can simultaneously heat the house and provide hot water.

Boilers also differ in the way they are installed. Wall and floor options are available. Each of them has its pros and cons, which is taken into account when choosing equipment.

The choice of device based on power depends on the size of the house (see:). In this case, the climate coefficient (Kk) is taken into account. For central regions (including Moscow) it is 1.2-1.4; southern regions – 0.8-0.9; north of the country – 1.4-2. The evaluation calculation is carried out using the formula KхS/10. For example, for a house in the Moscow region with an area of 120 m², it is advisable to choose a boiler with a capacity of 120x1.2/10, i.e. 14-15 kW.

Regulatory documentation

The main document regulating the installation of gas equipment in a private home is SNiP 42.01-2002 “Gas distribution systems”. It contains the most important rules and regulations.

In addition, it would be a good idea to familiarize yourself with the requirements and recommendations regarding heating and ventilation systems ( SNiP 41.01-2003), the procedure for ensuring gas supply ( SNiP 2 04.08-87). Useful information can be gleaned from SNiP 01/31/2003 on the procedure for installing gas equipment in residential buildings.

Installation approval

In order to legally begin installing a gas boiler, it is necessary to prepare and approve certain documents. First of all, it should be clarified in general possibility of gas selection in the required volume. To do this, an agreement (contract) is concluded on the supply of natural gas to an individual (individual developer).

The most important documents for connection are Specifications. They are issued by the relevant territorial gas service. To obtain a document, you must submit an application to such an organization, indicating the purpose of additional gas supply and the planned volume of gas consumption. Registration of technical specifications is carried out within 8-12 days.

Important! The issued document clearly states the installation installation features; from the moment of issuance, it is considered an official permit to begin work.

Project development

The technical specifications only fix the conditions for installing a gas boiler, but to begin installation of the equipment it is necessary to go through the following stage - development and approval of project documentation.

In essence, a “Gas Supply” project is needed, which clearly defines the installation scheme of the boiler itself and the supply of gas to the point of its selection from the central pipeline.

It is developed by specialized organizations that have the appropriate license. The document must be approved by the government organization entrusted with regulatory powers (usually Raigaz or Oblgaz).

The following documents are attached to the project for approval:

Technical passport for the equipment.
Gas boiler operating instructions.
Sanitary certificate and certificate of technical conformity.
Expert opinion on equipment compliance with technical requirements.

All specified documents must be provided by the equipment manufacturer. Depending on the complexity of the installation, project approval can last from 6-7 days to 2-3 months. If approval is refused, a reason must be provided indicating the necessary changes to the project. The final approved version of the project is certified by a seal.

Installation Rules

The heating boiler must be installed in a separate room, which is subject to increased requirements:

Gas equipment is installed in a specially designated room. In a private house, if all standards are taken into account, a boiler room can be installed on any floor and in the basement. It is not allowed to install a gas boiler in the living room, bathroom, bathroom and kitchen.
The minimum permissible area of the room is set based on the power of the boiler. The permissible minimum is 4 m².
The ceiling in the room must be raised to a height of more than 2.6 m.
Mandatory element in the room - opening window. The established norm is 3 cm² of window area for every 1 m² of the total area of the boiler room.
The entrance door to the room should be wider than 80 cm. At the top, between the doorway and the door leaf, a gap of more than 24 mm is left for natural ventilation.
It is not allowed to use flammable facing materials in the decoration of the premises. False ceilings or false floors should not be constructed.
The room must have sufficient lighting and a flow of fresh air.
It is necessary to exclude the accumulation of moisture in the boiler room. Humidification of the environment makes it difficult to remove gas vapors.
It is not allowed to operate a gas boiler without a water supply.

It must be taken into account that the requirements for the boiler room are mandatory. Taking into account the fact that violation of standards is fraught with danger, improper installation is punishable by fines and a ban on the operation of equipment.

Requirements for individual premises

A boiler room in a separate building is organized with a boiler power of over 150 kW or at the request of the owner with any equipment. This option increases safety and completely eliminates the penetration of gas into the house, but requires the installation of a heating main with reliable thermal insulation.

When constructing a separate structure, non-combustible building materials are used. Preference is given to block and brick masonry. For external cladding, metal multilayer “sandwiches” can be used. The floor is covered with reinforced concrete slabs. When arranging a roof, the emphasis is on metal profiles and non-combustible roofing materials.

A separate room must fully satisfy the above requirements. For boiler power over 100 kW, the minimum room area is set to 15 m². More powerful installations require adjustment of this indicator - 0.2 m² additionally for every 1 kW.

If the boiler has a mass of over 210 kg, then a foundation must be erected, which is independent of the foundation of the building itself. It rises above the floor level to a height of 12-15 cm.

Extension equipment

A special extension to a residential building is most often used for boilers with a capacity of 50-100 kW or in the absence of the necessary room for low-power equipment inside the house. This option is quite popular. In this case, it is important to provide fireproof protection to the wooden wall in the area where the extension comes into contact with it. Fire resistance must be provided at least 0.7 hours.

The extension premises must comply with all established standards. Increased requirements for the front door. It must be metal, open outward and be secured in such a way that it can easily fly out from the blast wave. Natural ventilation is an important requirement.

For air flow, the presence of holes and gaps is assumed, and their area is normalized by the following condition - 8 cm² for every 1 kW of boiler power.

Requirements for equipment and its elements

Gas supply to the boiler room is allowed only after inspection of the correct installation by a competent representative of the district or regional gas service. Before putting it into operation, the system must be pressure tested at a pressure of up to 1.9 atm.

Important! There should be no air remaining in the system, and all components should be checked for leaks.

The following general requirements for equipment and its parts must be met:

ensuring free access to equipment from all sides;
gas pipes can be made exclusively of metal;
a prerequisite is the presence of a gas flow meter;
the equipment must be reliably grounded according to the standards established for electrical installations;
to avoid emergency situations, it is necessary to install gas analyzer, indicating the presence of a gas leak and automatic valve to shut off the gas supply in case of depressurization.

The operation of a gas boiler is quite dependent on electricity. To eliminate problems, it is advisable to install a voltage stabilizer, as well as uninterruptible power supplies.

Ventilation and chimney installation

The most important element of a boiler room arrangement is a reliable ventilation system. It is intended to exclude:

accumulation of carbon monoxide and gas accumulation in the presence of small leaks;
elimination of soot settling on the surface of walls and ceilings;
providing comfortable conditions for service personnel.

Ventilation is provided by a combination of natural and forced methods.

Natural ventilation requires the presence of opening windows (in accordance with the specified standards), cracks in the doorway and special ventilation holes in the wall. They usually have a diameter of 12-16 cm, and their number depends on the area of the room and the power of the equipment.

The influx of fresh air occurs through the lugs at the bottom of the wall, and the outflow occurs under the ceiling on the opposite side of the wall or through the roof. The openings should be covered with a protective grill.

Forced ventilation increases the safety of equipment operation. When using powerful boilers, natural ventilation cannot cope, and therefore exhaust fans are installed. Exhaust and ventilation pipes are installed for drainage.

A chimney (more correctly, a gas outlet) is a mandatory element for a boiler room. The following requirements are imposed on its arrangement:

the boiler room chimney is a separate structure, not connected to other smoke exhaust systems in the house;
the horizontal section of the outlet cannot exceed 2.8 m;
number of knees (curvatures) – no more than 3;
the diameter of the outlet cannot be less than the connecting pipe;
the outer section of the chimney is installed above the roof and must rise above the ridge to a height of at least 60-70 cm.

The diameter of the chimney depends on the boiler power and must take into account the established ratio. So, with a power of less than 35 kW, the diameter is at least 13 cm, and with a power of 35-45 kW - 14 cm.

The need for utilities

In addition to an agreed connection to the gas main, the operation of gas boilers is impossible without a water supply and electrical network. Water supply in a significant volume, because water is the main coolant in the heating system. Such an additional point also requires approval from the relevant organizations and the installation of water flow monitoring devices.

Almost all types of gas boilers cannot operate without electricity. When connecting the electrical network, the total need for electricity is taken into account - for the boiler (according to the passport) and room lighting.

note

The line must be diverted from an individual switchboard equipped with a circuit breaker, a protection system and a meter.

Installation of a floor-standing boiler

Installation of a floor-standing gas boiler is carried out in the following order:

Forming a reliable foundation. For powerful boilers, a monolithic one is required, and for low-power equipment, a metal sheet is required.
Installing the boiler after checking the level of the base using .
Connecting the boiler to the chimney and checking the presence of the necessary draft.
Connecting heating system pipes. Installation of the water purification and hardness filter, as well as shut-off elements in accordance with the instructions. Ball valves are usually installed.
Supply and connection of water supply in the presence of a second circuit.

When installing equipment, it should be remembered that insertion into the gas main can only be carried out by a specialist with a special permit.

Conditions for placing a wall-mounted boiler

Another common type of equipment is wall-mounted gas boilers. Their installation is ensured in the following sequence:

The equipment is mounted on a load-bearing, high-strength wall or partition that meets fire resistance requirements.
The boiler body should be 45-55 mm from the wall surface and 50-60 cm from the adjacent wall. There should be a distance of at least 75 cm to the ceiling. The boiler is mounted strictly parallel to the floor surface.
Installation of a water filter and shut-off elements. Connection to the heating system.
Installation of a chimney, if provided for in the instructions.
Connection to the gas pipeline.
Electrical network connection.

When installing both types of boilers, it must be taken into account that it can only be carried out at room temperatures within the range of 6-34 degrees. After installation, the unit is slowly filled with water so that all air is displaced.

Equipment Maintenance

The operation of gas equipment must be carried out strictly in accordance with the instructions. You should always remember that any violations and gas leaks can lead to tragic consequences. Worn out and damaged equipment must not be used.

Boiler maintenance must be ensured at least 2 times a year. Before the onset of cold weather, it is carried out without fail and in full. The tightness of all connections, the condition of the chimney and ventilation system are checked. The filters and burner are thoroughly cleaned. If necessary, worn parts and sealing gaskets are replaced.

Gas boilers are increasingly used to provide heating and hot water supply to private homes. They are easy to use, and safety is guaranteed if installed and used correctly.

Installation of equipment must be ensured in full compliance with established standards. It is important to remember that uncoordinated connection of such boilers is a serious offense and is fraught with administrative punishment.

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 forbidden 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:

Important! Independent connection is strictly prohibited, especially to central highways. The first setup should be carried out by a specialist.

Before you begin building and equipping a boiler room, you first need to purchase the right boiler. Then, based on its power, select the size of the room, while observing all the necessary requirements. To save money and time, it is recommended that you first familiarize yourself with all the rules and only then proceed to arranging the room that will serve as a boiler room.

The problem, which is associated with the lack of central heating and hot water supply, as well as the poor quality of these services, can today be solved by installing a gas boiler.

Boiler selection

To do this, you can choose single-circuit or double-circuit equipment. The first option can provide only one process, which can be, for example, heating. Whereas dual-circuit equipment guarantees two processes, namely heating and water heating. Installing a gas boiler in a private house is quite troublesome and time-consuming, this is largely due to the fact that the master will have to ensure compliance with all rules and regulations. It is also worth remembering that the operation of such equipment is always associated with some risks, which is why it is necessary to follow fire safety rules.

Basic rules for installing gas equipment

If you decide to install a gas boiler in a private house, you will need to prepare documents and carry out certain actions. A contract for the supply of gas to an individual consumer will be needed. The installation project, as well as all technical conditions, must be agreed upon with the city gas service representative. The heating system must be pressurized to 1.8 atm.

It will be important to de-air the heating system. The technician will have to analyze the connections for leaks. A voltage stabilizer is installed for the boiler; it is important to take care of the presence of an uninterruptible power supply. It is unacceptable to add antifreeze to heating water. This can cause damage to the gaskets, leading to leaks in the heating system.

Premises requirements

If you decide to install a gas boiler in a private home, it is important to check whether the room complies with the standards. We are talking about the room in which the boiler is supposed to be placed. in a single-family house may involve the installation of a furnace or boiler room at any level, this could be the roof, attic, basement or basement. The restrictions are the living quarters, as well as the bathroom and bathtub. To determine the volume of the room that will play the role of a boiler room, it is necessary to take into account the total thermal power of the equipment, capacitive or instantaneous water heaters. When installing a gas boiler in a private home, it is recommended to take into account that there are some exceptions. Thus, if the boiler has a closed combustion chamber, then the volume of the boiler room is not standardized, and a window with access to the outside may also not be installed.

Air flow

To remove and supply air, it is important to organize an influx of the required volume. In order to provide equipment power of 23.3 kW, about 2.5 cubic meters of gas must be burned per hour. In order for this volume to burn completely, you will need 30 cubic meters of air for an hour. If an insufficient amount of oxygen is supplied, the gas will not burn completely, and ultimately a harmful substance will begin to accumulate, while its inhalation will have a negative impact on human health.

If you do it yourself in a private house, then it is especially important to ensure that air flow is ensured not only from outside, but also from other rooms of the house. This can be achieved by creating a gap between the floor and the door. It is necessary to mount the boiler on the floor with a step of 10 cm from the wall, which is important to cover with non-flammable material.

Features of work on the installation of gas equipment

Installation of a gas boiler in a private house, the price of which should interest you at the first stage, requires compliance with rules and regulations. When planning the room in which you intend to place the boiler, you need to make it such that the area is 4 square meters or more. Ceilings must be 2.5 meters high or more. It is important to pay attention to the width of the door that goes into the room; it should be equal to 80 cm. Installation of a wall-mounted gas boiler in a private house is carried out in such a way that the equipment is illuminated naturally through the window opening.

It is important to note that for every 10 square meters there should be 0.3 square meters of window. It is necessary to provide intensive ventilation, since gas combustion is carried out due to the flow of air. The area of the opening for the intake of outside air should be 8 square centimeters per 1 kW of equipment power.

When installing a floor-standing gas boiler in a private house, it is important to take into account the fact that the gas pipeline pipes must be made exclusively of metal. It is important to remember that flexible hoses can only be used to connect consumers.

What you need to know about the chimney cross-section

The cross-section of the chimney should not be neglected, which must correspond to the available power of the boiler. If the equipment power is 30 kW, then the chimney diameter should be equivalent to 130 millimeters. When installing gas boilers, the rules and installation features require the use of a chimney with a diameter of 170 millimeters with an equipment power of 40 kW. It is unacceptable for the cross-sectional area of the chimney to be smaller than the cross-sectional area of the hole for connecting the chimney. The upper end of the chimney should be 0.5 meters or more higher than the roof ridge. The electrical power supply system of the equipment must have a circuit breaker equipped with thermal and current protection.

Features of installation of boiler equipment

If you are carrying out installation, a gas boiler for heating a private house must work in conjunction with a gas analyzer, which will be able to warn of a possible gas leak. Among other things, you need to make sure there is an electric valve that shuts off the fuel supply. If you have to work in an apartment building, installing gas equipment in the basement is unacceptable. Each device must be supplemented with gas meters. As for ventilation, it should be in the upper part of the room.

Features of installing wall-mounted equipment

When installing gas boilers in a private house, the work flow diagram allows you to eliminate errors. Wall-mounted equipment is mounted in cases where power requirements are not too strict. Among other things, this arrangement of equipment can be chosen when there is not too much free space. Most often, such boilers are used in multi-storey buildings. Installation of wall-mounted equipment allows you to provide an autonomous additional heating system, which can be installed even in houses with central heating. Do-it-yourself installation of a gas boiler in a private house can be done above other appliances that are installed on the floor, this is due to the fact that boilers are not too demanding on free space. It is permissible to mount wall-mounted equipment in cascade. This is advisable if there is a need for significant power.

Installation of indirect heating can be done at a distance of 20 centimeters from other gas appliances, as well as materials that are flammable. Depending on the equipment model and power, the distance between the boiler and the wall can vary from 30 to 50 centimeters. It is not recommended to place the boiler near a window or in an opening between walls. The power source should be located as close as possible. Before the boiler is installed in its place, all pipes, equipment and systems must be flushed with water. This will get rid of foreign particles that may have entered the system during the assembly process.

Nuances of the work

The strips that are used to fix the boiler must be installed in increments of 0.8 meters; as for the maximum distance, it is 1.6 meters from the floor surface. It is necessary to analyze the wall for evenness and strength; it must support the weight of the boiler itself and the associated devices. When produced in a private house, the wall is provided with a gasket made of non-combustible material, the thickness of which should be 3 millimeters. In this case, the boiler is fixed at a distance of 4.5 cm from the wall surface.

Before the equipment is connected to the pipes, it is necessary to remove the plug that is installed on the pipes. In order to prevent clogging of the heat exchanger, it is recommended to install a corner strainer at the water inlet. It is important to install ball valves on both sides; this should greatly simplify further maintenance and repairs. Afterwards, it is important to check how level the equipment is installed. Skewing to one side can lead to negative consequences. Gas pipes should be connected to the equipment using a steel pipe through special fittings; it is important to ensure a rigid connection. Important to apply At this point we can assume that the installation of a gas boiler in a private house, the price of which starts at 5,000 rubles, has been completed.

Requirements for the chimney device

It is important to choose the right material for the chimney, which will depend on the type of equipment and fuel used. For a gas boiler, it is necessary to use pipes that are cylindrical in shape and made of metal; it is preferable to use stainless steel. Such products will be the safest, most reliable and durable. It is important to install a hatch to clean the chimney. In order to make it convenient to collect soot during the cleaning process, it is necessary to leave an empty space under the chimney entrance. When installing this part of the boiler equipment, you should not make more than three turns and bends.

The pipe that connects the chimney to the boiler should be as short as possible, its length no more than 25 cm. The vertical section at the outlet of the equipment should be equal to 2 diameters or more. Beyond this section, the pipe must be brought out to the connecting section, and after that it must be turned upward with a slight slope towards the equipment. Smoke removal in this case will be carried out due to natural draft.

Conclusion

The cost of installing a gas boiler in a private house will be less if you install all the equipment yourself. However, it is necessary to take into account the fact that the connection of the system is still carried out by a professional team of craftsmen. This is necessary to ensure that all fire safety rules and regulations are strictly observed. After all, this is the only way to protect yourself and your home from a fire that may occur due to improperly installed heating equipment.
