Wall mounted gas boiler distance from the wall. What are the requirements for a room for installing a gas boiler in a private house?

The well-known principle is that it is better to do everything right once, to comply with all requirements, than to redo it a hundred times later. Unfortunately, not all "kulibins" of our country use it. Often there are situations when an “experienced” homeowner himself knows where to install gas equipment and at the same time violates all conceivable and unimaginable norms. In this case, there will be no permission to connect, and the funds spent cannot be restored. Do not forget that compliance with safety requirements when planning gas heating is not a whim of gas workers, but a well-founded concern for safety human lives. In this regard, it is imperative to consult with a specialist and study in detail the requirements that are established for a room with a gas boiler. Consider exactly what points to pay attention to when organizing individual heating in order to avoid problems and unnecessary fuss.

Boiler room in a private house. Norms and requirements for it

The best option is to equip a separate room in the house for the boiler room. The characteristics of such a room must comply with those presented in SNiP 31-02-2001, DBN V.2.5-20-2001, SNiP 11-35-76, SNiP 42-01-2002, SP 41-104-2000. These documents are designed specifically to minimize the possibility of any emergency. A room with a gas boiler is considered the most fire and explosive in the house, therefore, it is necessary to take the choice of a suitable boiler room and the correct layout as responsibly as possible. Depending on the total heat output of the gas boiler, the required volume of the room is also calculated. If the power of the gas boiler is less than 30 kW, then the minimum volume of the room is 7.5 m3, 30-60 kW - 13.5 m3, and for a boiler with a power of more than 60 kW, a room of 15 m3 is already needed.

The second significant indicator when choosing a boiler room is the height of the ceiling. It should be at least 2.5 m. It is worth paying attention to the location of the load-bearing walls in the house. It is desirable that between the boiler room and other rooms it is the main walls that are located. It is important to pay attention to the interior decoration of the walls. The easiest option is refractory plaster.

If white walls do not fit into the overall interior of your home, then be sure to consider that all materials used must be safe. Do not use flammable or easily flammable substances. That is, no parquet and laminate, as well as wallpaper and plastic panels, will decorate the walls of the boiler room either.

Be sure to have certain parameters of the door, window and ventilation. The doorway should not be narrower than 0.8 m, and the size of the window is calculated based on the volume of the room: 0.3 m² per 10 m3 of the boiler room. Be sure to provide an interval of several centimeters between the door and the threshold. This will ensure air exchange with other rooms. Do not forget about the influx of fresh air from the street.

Requirements for the kitchen when installing a gas wall-mounted boiler

If the number of residential square meters is limited and it is not possible to allocate an entire room for a heat source and hot water, then the way out of the situation will be the placement of a wall-mounted gas boiler in the kitchen. This option is allowed by regulatory documents, but subject to certain requirements. We can say that this is a simplified version of the boiler room, so the requirements for the room will be similar.

Ceiling height - 2.5 m or more;
Kitchen area - 4 m² or more;
The ventilation area is calculated according to the boiler power - 8 cm² per 1 kW. It will be located in the upper part of the room;
Be sure to have a window with a window;
Depending on the power of the boiler, the cross section of the chimney is calculated: 30 kW - 130 mm, 40 kW - 170 mm;
The chimney pipe must exceed the roof ridge by half a meter and have a protective umbrella.

The choice of a specific place for a boiler in the kitchen should be approached based on the following criteria:

distance to other gas units at least 20 cm;
distance to flammable surfaces - 20 cm;
distance from the wall - 30-50 cm;
avoid places in niches, gaps between walls, and in close proximity to windows.

The advantage of installing a gas boiler in the kitchen is also the presence of pre-installed communications: water, electricity, ventilation. And this is a direct cost savings.

Coordination of the boiler installation with the gas service

Before proceeding to the direct installation of equipment, it is necessary to go through several bureaucratic instances and fulfill their requirements. The first step is to write an application to the local gas service and get the technical conditions for installing the boiler. The application shall indicate the applicants and a brief description of Houses.
Be sure to indicate which gas-using equipment you plan to install (brand, capacity) and attach a list of documents:

Copies of title documents for the land plot on which the capital construction object owned by the applicant is located (will be located).
Situational plan for the location of the land plot with reference to the territory of the settlement.
Calculation of the planned maximum hourly gas flow (not required if the planned maximum hourly gas flow is not more than 5 m3).

The second stage is the creation of a project for the installation of gas equipment. For a private house, a plan or diagram of pipe wires is being developed along the site, as well as their entry points to the equipment installation site. The project is confirmed in government bodies gas service is approved and you can proceed to the direct installation.

Each of these stages takes an average of 1.5 - 2 weeks. So if you decide to radically change the heating system at home, then take care of this issue at least a month before the onset of cold weather.

Thus, observing all the norms for a room with gas equipment, you will ensure trouble-free operation of a gas boiler. By following all the requirements, protect your family from any emergency situations related to gas equipment. Get rid of administrative penalties and censures from gas services for violations of requirements.

A gas heating boiler for private households is considered one of the best options because it has a high efficiency and makes it easy to adjust the intensity of heating. The cost of purchasing and installing this heating unit will pay off quickly enough, since gas as a fuel is economically viable.

When it is planned to install a gas boiler in a private house, the requirements for it and the room where it will be located should be clarified in advance. As practice shows, the owner of the property will have to prepare a solid folder of various documents and obtain permits from certain authorities. This is not a pleasant occupation, but it is necessary.

Documents regulating the installation of a gas boiler

First of all, before proceeding with the installation of gas equipment in a private house, it is advisable for its owner to familiarize himself with the regulatory documentation containing all the rules and requirements that will need to be followed when creating autonomous heating.

All the required information can be found in SNiP 31-02-2001. In addition to these Building Regulations and Rules, you need to familiarize yourself with other documents, including: SNiP 41-01-2003; 21-01-97; 2.04.01-85. The rules for installing a boiler house in a private household are regulated by SNiP 2.04.08-87.

Installation approval, regulatory requirements

In order for the installation and connection of a gas boiler in a private house to be carried out, it is not enough to read SNiPs. First of all, you need to obtain technical conditions, which in the future will be the basis for performing work related to connecting the device to centralized gas networks.

The property owner must submit an application to the service responsible for the gas supply at the place of residence. It should indicate the planned gas consumption for heating the house and for other domestic or household needs. This parameter has an approximate value, based on the standards prescribed in SNiP 31-02.

So, the volumes of gas per day for a single-family home are:

for cooking on a gas stove -0.5 m³;
for supplying hot water by means of a flow-type gas heater -0.5 m³;
for heat supply by a gas unit with a laid water circuit - from 7 to 12 m³ for Russian regions of the middle lane.

In the local service that controls the gas supply and installation of boiler equipment, the submitted application is considered by specialists. As a result, the owner of the building receives a document in which the technical conditions are prescribed or a reasoned refusal is given.

The procedure for considering an application for installing a gas boiler in a private house usually takes from 7 to 30 days, which depends on the speed of decision-making in this controlling organization. If the request is satisfied after receiving the technical conditions, they must be fully implemented during the installation of the equipment.

A document with a positive decision is also considered a permit for the installation of a gas boiler, and therefore for the start of the relevant work. Every homeowner should be aware that it is illegal to install this type of device without specifications. In addition, an independent unauthorized installation of the boiler is not safe.

Designing a gas boiler installation in a private house

When the owner of the object has received the technical specifications, he can begin to draw up project documentation. It is developed on the basis of the requirements set forth in the technical conditions.

The project for the installation of a gas boiler must contain a diagram describing the laying of gas communications, and for private households - in the area before entering the residential building, indicating this place on the drawing.

The project should be developed exclusively by design engineers who have received a license to carry out this type of work. Usually, in an organization that controls gas supply in a settlement or region, there is a design department, whose employees perform the necessary surveys, relevant calculations and draw them up in the form of projects with drawings and diagrams.

Approval of project documentation

Then the developed project is sent for approval to the territorial office of the organization that controls the gas supply of the household, where the equipment will be installed.

The time period required for this depends on how complex the scheme for installing a gas boiler in a private house and laying gas communications is. It can range from 7 days to 3 months.

Documents are attached to the project that requires approval, which describe the characteristics of the equipment for the boiler room:

Technical passport of the gas appliance.
Manufacturer's instructions for its use.
Certificates confirming the compliance of the equipment with sanitary and hygienic and technical parameters.
Expert opinion that this unit meets all safety requirements.

All of the above documents are issued to the one who purchases the device, and they are issued by the manufacturer of heating equipment.

There are situations when a project does not receive an approval resolution. Then, in addition to a reasoned refusal, the applicant should be given a list of necessary actions, as a result of which it will be possible to obtain a positive verdict. When the project is approved, it is formalized accordingly. Now you can proceed to practical activities related to the installation of a gas boiler in a private house.

boiler room requirements

To use gas equipment with a power of 30 kW or more, you will need a separate room that complies with all applicable rules and regulations.

Most often, one of the rooms in the basement or basement is equipped as a boiler room. True, such an installation of a heating unit is allowed only for single-family residential buildings.

In private households, the rules for installing a gas boiler allow the use of equipment of any power, since most often it is placed in a separate room attached to the house, which allows you to provide heat not only for living rooms, but also for utility rooms.

Important requirements that the boiler room must meet are as follows:

The area of the minimum room for a gas boiler based on one unit is 4 m². At the same time, more than two devices cannot be placed in one room. This size of the boiler room in a private house is required.
Ceiling height should be at least 2.0-2.5 meters.
To provide natural light, it is necessary to have a window, the size of which is determined at the rate of 0.3 m² per 10 m³ of the volume of the room for a gas boiler, but not less than 0.5 m². A certain distance from the gas boiler to the window is also provided, in terms of safety.
The width of the doorway cannot be less than 80 centimeters.
The minimum distance from the front door to the unit is -100 centimeters, but it is better if it is 130–150 centimeters.
In order to create conditions for the implementation of repair or preventive measures, a free space of at least 130 centimeters should be provided in front of the boiler.
Proper installation of a gas boiler in a private house means that it is located in a horizontal position and is stable. This minimizes the possible noise level due to vibration.
The floor and walls must be made of non-combustible materials, in addition, the floor covering must be absolutely even.
It is necessary to carry out to the boiler room cold water, and equip the sewer drain for the coolant in the floor.
For electrical outlets, a ground loop is required, since the ignition or pump is connected to the power supply.
Easy access to the chimney, or rather to the inspection window, should be provided in order to control the patency of the channels and clean them.

Ventilation and smoke removal

The rules for installing a gas boiler in an apartment and a private house provide for the arrangement of ventilation systems and the removal of gas combustion products in the boiler room. Their malfunction or ineffective functioning may result in equipment failure or lead to an emergency.

The regulatory documentation for ventilation and chimney in a private household lists a number of requirements:

Smoke exhaust and ventilation channels cannot be combined, they are made separate.
In order for fresh air to enter the boiler room, forced ventilation should be installed in it. The entrance window is arranged at the bottom of the door or outer wall. The size of the ventilation window opening should be at least 1/30 of the area of the room, but not less than 80 mm² per 1 kW of boiler power in the case when the air flow comes from the street, and at least 300 mm² per 1 kW if from other sources.
Ventilation ducts should always be kept open, as air flows must constantly circulate.
The boiler is recommended to be located in close proximity to the chimney.
The chimney installed in the wall should have two inlet channels, while the main one is intended for installing a chimney, and the other is revision, for technological cleaning, it is located below the first one by at least 25 centimeters.
The cross section of the chimney exhaust opening cannot be less than the same parameter for the outlet pipe of the gas unit.
The chimney structure should not have more than three bends and turns.
For the manufacture of chimneys, stainless or carbon steel is used. Installation of asbestos-concrete or other pipes made from laminated materials is allowed at a distance of at least 50 centimeters from the flue pipe of the heating unit.
In order to ensure the safe operation of the device and the efficient operation of the heating system, it is necessary to create conditions to maintain the required traction force. Therefore, it is necessary to calculate both the entire height of the chimney pipe and the height of its location above the roof surface so that the head is not in the zone of wind backwater.

The rules and conditions for the installation of a gas boiler set the standards for its chimney design:

the pipe should rise above a flat roof without a ridge no less than 50 centimeters above the roof or parapet, if it is equipped along its perimeter;
when the chimney passes through the roof slope at a distance of at least 150 centimeters from the ridge, then the pipe head must be raised by at least 50 centimeters;
if the chimney outlet through the pitched roof is laid at a distance of 150-300 centimeters from the ridge horizontally, it is necessary to raise the head to a level not lower than the top point of the ridge;
in the case when the pipe passes through the pitched roof at a distance of more than 300 centimeters from the ridge, then its outlet is located on a conditional line drawn at an angle of 10 degrees from the top of the ridge to the horizon.

Information about gas boilers

In the domestic market, consumers are offered an extensive range of gas equipment. To make the right choice, you need to study the information on heating units from different manufacturers.

Gas boilers are divided into several types depending on:

constructive device;
installation method;
rated power;
ignition principle;
technologies for the removal of combustion products.

According to the basic design, the units are single- and double-circuit:

Boilers of the first type are needed to provide a heating system, and if you plan to use them for hot water supply, you will need a device called an indirect heating boiler. This unit is designated as a heating gas water heating unit, abbreviated as AOGV.
Double-circuit models are able to provide both heating of the household and supply residents with hot water. They can function as a flow-through heating option, or be equipped with a built-in boiler. It not only heats the water, but also maintains some of its supply. On double-circuit devices, the letter designation AKGV is applied - a combined gas water heating unit.

Depending on the method of installing a floor-standing gas boiler in a private house, it can be either wall-mounted or floor-mounted:

Wall models are becoming increasingly popular, as they are used even in apartment conditions. They are convenient in that the construction of a structure that removes smoke is not required to remove combustion products. Smoke extraction can be carried out directly to the atmosphere through an external wall by installing a coaxial chimney, which also provides the air supply necessary for burning fuel.
Floor-mounted units differ from wall-mounted models in greater power. Installation of a floor-standing gas boiler in a private house is usually performed in boiler rooms so that they do not clutter up domestic premises.

Today, all manufactured heating units are equipped with automatic protective systems of various levels of complexity, but in any case, they provide for the shutdown of the fuel supply to the burners in the presence of leaks or interruptions in the operation of the gas main, excessive heating of the coolant or insufficient draft force in the chimney.

Before purchasing a boiler, you should pay attention to its power in kWh, which means the production of a certain amount of thermal energy per unit of time. The optimal model is selected taking into account this parameter based on the calculations performed, depending on the heated area and the size of the gas boiler for a private house.

For calculations, use the formula W \u003d S × Wsp / 10, where:

W is the power of the device;

S - heated area;

Wsp - specific power for heat supply of 10 m².

Depending on the region of location, the specific power may vary. For example, if for the northern regions it is 1.5 - 2.0 kW, then for the southern regions it is different - 0.7 - 0.9 kW.

But such an approach to determining power cannot be called accurate, since it does not take into account the characteristics of a particular household. Before installing a gas boiler in a private house, you can turn to specialists with extensive experience in carrying out such calculations, who will calculate this parameter for each room. Knowing the exact amount of power, it is not difficult to make the optimal choice of gas equipment.

Rules for installation and connection of a gas boiler

Before connecting a gas boiler in a private house, its owner must contact the gas service specialists who have undergone special training and have been certified, and also have a license to carry out such work.

Professional installation is a costly undertaking, but its high-quality implementation and safe living in a private house will be guaranteed.

There are times when property owners are allowed to independently install a gas unit, but for this you must obtain personal permission from the controlling organization. But even in such a situation, specialists should still accept the installed equipment, as well as perform a trial run.

The beginning of the installation of the heater consists of several stages:

First of all, you should make sure that the necessary operating conditions for a gas boiler in a private house are created and that all components are prepared for its installation. To do this, you need to read the technical condition for the device again and study the previously approved project.
Then the floor boiler is placed on a prepared, reliable, solid and even base made of non-combustible materials. The best surface on which to install a gas appliance is a concrete screed. Ceramic tiles or a sheet of metal are laid on it. The base must have such an area that it covers the space in front of the firebox in front of the boiler by about 40-50 centimeters.
If the design provides for the presence of legs, it should be ensured that the unit rests completely on them. An unstable location in this case is unacceptable.
Wall models are hung on the walls at a height of 100-160 centimeters from the floor using brackets or mounting brackets supplied with the equipment. Their locations are marked using the building level.

It must be remembered that the installation of a gas boiler in a boiler room or other room is carried out in such a way that it is at a distance from electrical appliances, and access to it is from all sides.

There are certain rules for the location of a gas boiler in a private house - they provide for compliance with a certain distance to the ceiling and walls:

From the surface of the unit to the uninsulated ceiling, the gap must be at least 120 centimeters.
From the side wall of the floor model to the wall without protective insulation cannot be less than 32 centimeters. When a sheet of asbestos is attached to the wall, covered with a metal sheet, then the gap can be reduced to 26 centimeters.
There must be at least 50 centimeters between the unprotected wall and the chimney. If the wall is covered with asbestos and a sheet of metal, the gap can be reduced to 25 centimeters.

Both hinged and floor models of boilers must be connected to the chimney system. To do this, they have an outlet pipe, its connection to the chimney is made absolutely tight, since even through small gaps combustion products can leak. This work is carried out, adhering to the “smoke” docking technology. To do this, the unit's branch pipe must be inserted into the socket of the flue pipe.
When connecting the boiler to the water supply system, a sump is installed before entering the device - this is the name of the coarse water filter. On both sides of it, stopcocks are mounted, necessary to shut off the water flow in case of replacing or cleaning the filter. It is advisable to install a filter with a similar piping on the return pipe of the water circuit in front of the boiler. As a result, due to the cleaning of the coolant, the heat exchanger will not clog.
Usually, a circulation pump is also mounted on the return pipeline, which should be tied with a bypass and stopcocks, so that, if necessary, it is possible to switch the circulation mode from forced to natural.
It is advisable to choose the connection point to the water supply before the first branching of the pipes of the circuit and as close as possible to the entrance of the pipeline into the wall. This measure helps to ensure the required pressure level in the process of filling the heating system.
In floor-standing models, the pipe for connecting the pipes for supplying the water circuit is made in the upper part of the boiler, and the “return” pipe is located at the bottom. In wall-mounted units, both nozzles are located at the bottom.
The gas supply pipe to which the supply to the unit is connected must be equipped with a valve to shut off the gas supply.

When the installation of the heating boiler and its connection to the heat supply circuit is completed, the equipment is tested for tightness. This process, called "crimping", is carried out by specialists who for this use devices that create excess pressure in the system. During testing, there should be no leakage of coolant at the joints.

Authorized employees of the gas service are required to check the tightness of the connection of flexible hoses and all components of the gas block of the device. After that, they conduct a test run of the unit and check the correct functioning of its operation in different operating modes.

After the completion of the control and testing activities, if the conditions for installing a gas boiler in a private house are met and the device works flawlessly, the controllers draw up an act - a permit document that allows it to be operated.

Basic rules for using a gas unit

It is necessary to use heating gas appliances in compliance with certain rules:

The boiler room or other room should always be dry.
Filters for the heat carrier should be cleaned of dirt in a timely manner in order to extend the life of the heat exchanger.
It is strictly forbidden to make independent changes to the structural device of the boiler.
Cleaning of the flue structure pipe from combustion products deposited on its walls should be carried out in a timely manner.
In a private household or boiler room, it is advisable to install a gas analyzer that helps to identify malfunctions in the functioning of gas equipment.
Timely maintenance of the heating unit should not be avoided, which experts recommend to carry out before the start of the heating season and after its completion. To do this, you need to invite a master who will comprehensively check the condition and operation of the chimney, ventilation system, filters, burner and boiler as a whole.

A qualified installation and compliance with preventive measures can ensure the long and trouble-free operation of gas equipment, and, accordingly, the entire heating system of a household.

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 strictly followed, because not only the quality of operation, but also safety depends on this.

Preparation for the installation of a gas boiler in a private house includes important steps for its design and coordination of installation with the relevant organizations. At this stage, the selection or construction room for placing the boiler, and also selected required type of equipment.

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

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

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. There are wall and floor options. Each of them has its pros and cons, which is taken into account when choosing equipment.

The choice of device for power depends on the size of the house (see:). In this case, the climatic coefficient (Kk) is taken into account. It is for the central regions (including Moscow) - 1.2-1.4; southern regions - 0.8-0.9; north of the country - 1.4-2. Estimated calculation is carried out according to the formula КкхS/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 house is SNiP 42.01-2002 "Gas distribution systems". It contains the most important norms and rules.

In addition, it would not be superfluous 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 31.01-2003 on the procedure for installing gas equipment in residential buildings.

Installation approval

In order to legally start the installation of a gas boiler, it is necessary to prepare and agree on certain documents. First of all, it should be clarified the possibility of extracting gas in the required volume. For this, an agreement (contract) is concluded on the supply of natural gas to an individual (individual developer).

The most important documents for connecting are Specifications. They are issued in the relevant territorial gas service. To obtain a document, you must apply 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 specifies the installation features of the installation; from the moment of issuance, it is considered an official permission to start work.

Project development

The technical specifications fix only the conditions for installing a gas boiler, but to start installing the equipment, you must go through the following stage - development and approval of project documentation.

In fact, the Gas Supply project is needed, which clearly defines the scheme for installing the boiler itself and supplying gas to the point of its selection from the central highway.

It is developed by specialized organizations that have the appropriate license. The document must be approved by the state organization, which is entrusted with supervisory powers (usually Raygaz or Oblgaz).

The following documents are attached to the project for approval:

Technical passport for equipment.
Instruction manual for gas boiler.
Sanitary certificate and certificate of technical conformity.
Expert opinion on the compliance of equipment with technical requirements.

All of these documents must be provided by the equipment manufacturer. Depending on the complexity of the installation, project coordination can take from 6-7 days to 2-3 months. In case of refusal to agree, a motivation should be issued indicating the necessary changes in the project. The final agreed 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 mounted in a specially designated room. In a private house, taking into account all the norms, a boiler room can be equipped on any floor and in the basement. It is not allowed to put a gas boiler in the living room, bathroom, bathroom and kitchen.
The minimum allowable area of the room is set based on the power of the boiler. Permissible minimum - 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 norm is set - 3 cm² of window area for every 1 m² of the total area of \u200b\u200bthe 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 combustible facing materials in the decoration of the room. Do not make false ceilings or raised floors.
The room should have adequate lighting and 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 plumbing.

It should be borne in mind that the requirements for the boiler room are mandatory. Given that violation of the rules is fraught with danger, improper arrangement is punishable by fines and a ban on the operation of equipment.

Requirements for individual rooms

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

During the construction of a separate structure, non-combustible building materials are used. Preference is given to block and brickwork. For external cladding, metal multilayer "sandwiches" can be used. The floor covering is made of reinforced concrete slabs. When arranging the roof, the emphasis is on a metal profile and non-combustible roofing materials.

A separate room must fully meet the above requirements. With a boiler power of more than 100 kW, the minimum area of the room 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 more than 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.

Annex 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 premises for low-power equipment inside the house. This option is quite popular. In this case, it is important to provide fireproof protection of the wooden wall in the area where the extension comes into contact with it. Fire resistance must be at least 0.7 hours.

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

For air inflow, it is assumed that there are holes and gaps, and their area is normalized by such a 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 the correct installation has been verified 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 must be no air left in the system, and all components must be checked for leaks.

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

ensuring free access to the 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 in accordance with the standards established for electrical installations;
to avoid emergencies, it is necessary to install gas analyzer, signaling 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 sufficiently dependent on electricity. To eliminate problems, it is advisable to install a voltage stabilizer, as well as uninterruptible power supplies.

Arrangement of ventilation and chimney

The most important element in the arrangement of the boiler room is reliable ventilation system. It is designed to exclude:

accumulation of carbon monoxide and accumulation of gas 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 involves the presence of opening windows (in accordance with the specified standards), slots 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 \u200b\u200bthe room and the power of the equipment.

The inflow of fresh air occurs through the lugs in the lower part of the wall, and the outflow occurs under the ceiling on the opposite side of the wall or through the roof. Openings should be covered with a protective grille.

Forced ventilation increases the safety of equipment operation. When using powerful boilers natural ventilation will not cope, and therefore exhaust fans are installed. For removal, exhaust, ventilation pipes are mounted.

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

the chimney of the boiler room is a separate structure that is not connected with other smoke exhaust systems in the house;
the horizontal branch section cannot exceed 2.8 m;
the number of knees (curvature) - no more than 3;
the outlet diameter cannot be less than the connecting pipe;
the outer section of the chimney is led 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 power of the boiler and must take into account the set 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 engineering communications

In addition to the coordinated connection to the gas main, the operation of gas boilers is impossible without a water supply and electrical network. Water supply in a significant amount, because. water is the main heat carrier in the heating system. Such an additional point also requires coordination with the relevant organizations and the installation of water flow control devices.

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

note

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

Installation of a floor boiler

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

Building a solid foundation. For powerful boilers, a monolithic one is required, and for low-power equipment, a metal sheet.
Installing the boiler after checking the levelness of the base with .
Connecting the boiler to the chimney and checking for the necessary draft.
Connecting the pipes of the heating system. Installation of a filter for cleaning and water hardness, as well as locking elements in accordance with the instructions. Ball valves are usually installed.
Summing up and connecting the water supply in the presence of a second circuit.

When installing equipment, it should be remembered that tapping 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 provided in the following sequence:

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

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

Equipment maintenance

The operation of gas equipment must be carried out strictly in accordance with the instructions. It should always be remembered that any violations and gas leaks can lead to tragic consequences. Do not use worn or damaged equipment.

Boiler maintenance must be provided 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 the ventilation system are checked. The filters and burner are thoroughly cleaned. If necessary, worn parts and seals are replaced.

Gas boilers are increasingly used for heating and hot water supply of private houses. They are easy to operate, and safety is guaranteed when properly installed and operated.

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

Attention!!! Installation of a gas meter is carried out by specialists of JSC "Gazprom gas distribution Barnaul

The premises in which the gas boiler will operate are specified in SNiP 31-02-2001, DBN V.2.5-20-2001, SNiP II-35-76, SNiP 42-01-2002 and SP 41-104-2000 - these documents exclude or minimize any emergency situations. Premises for placing gas boilers fall under the classification of fire and explosion hazards, therefore, when designing, planning, installing and configuring equipment for gas heating, all requirements for a room for installing a gas boiler must be strictly observed.

General requirements for the installation of gas appliances

In the room intended for the installation of a gas boiler, in accordance with the above standards, there must be good daylight: per 1 m 3 there should be at least 0.03 m 2 of the area of \u200b\u200bthe window opening (but not windows - partitions, frames and imposts are not taken into account). Be sure to equip the room with a supply and exhaust ventilation system according to the following rules: the total volume of direct and reverse air flows per hour, multiplied by 3, is equal to the volume of the entire exhaust device. In addition to the window equipped with a window, a door with access to the street is installed in the room. The table shows the requirements for the volume of the room:

Attention!

For gas-fired units with a power of more than 6000 W, 0.2 m3 should be added for each extra unit of power.

Supervisory requirements for a room for installing a gas boiler stipulate that it is allowed to operate any devices for heating an apartment on each floor of a multi-storey building and in any room of the apartment. Kitchens in multi-storey buildings are also suitable for these requirements, as they are already equipped with the appropriate communications. The only condition is that the total thermal power of all devices for heating water and heating an apartment (boilers, boilers, heating elements, heating radiators, batteries or registers) should not exceed 150 kW in total.

The height of the ceilings in the room is 2 meters or more. The room in which the gas boiler will be installed and operated must be separated from neighboring rooms by solid refractory walls. Material for walls or partitions must have a temporary fire resistance limit of 0.75 hours (45 minutes). The room for the boiler must be planned so that in the event of a fire in operation there is no possibility for the fire to spread throughout the apartment.

Attention!

Gas boilers of the TLO brand, operating on the principle of natural circulation of the coolant, can be installed and should only be operated in the basement of the house or in the basement.

Installation of a gas wall-mounted boiler - kitchen requirements

Ceiling - 2 meters and above.
The total volume of the kitchen is more than 7.5 m 3 , ventilation is installed, a window is installed and there is a door leading to the balcony.
For air exchange, it is necessary to equip a grate at the bottom of the wall or door that opens into the next room, the area of \u200b\u200bthe grill is at least 0.02 m 2.

To install a gas boiler in the kitchen, you may need permission from the gas service.

If the kitchen in the apartment does not meet the requirements of SNiP, then gas heating equipment can be installed and operated only with the permission of the gas supervision.

The existing rules for installing a gas boiler in a private house largely repeat the requirements for boilers that operate in apartments in multi-storey buildings. The differences are caused only by the fact that often in a private house a separate room or building is allocated for heating equipment, which is subject to additional requirements listed below.

Rules for installing a floor-standing gas boiler

In a house under construction, it is necessary to plan a separate room for installing a gas-fired boiler. The room should be with natural air flow through the grate in the door or through a hole in the wall.
Be sure to make a separate hole for supply and exhaust ventilation - it must be under the ceiling.
A hole in the wall for a chimney, a hole below the chimney for a soot duster (for cleaning the chimney), which is made 20-30 cm below the main chimney.
The chimney is made airtight so that smoke and carbon dioxide do not get back into the room. For tightness, a smaller diameter pipe is installed inside the large chimney pipe, through which the products of gas combustion are removed.
The room intended for the installation and operation of the gas boiler must be spacious and provide free access and operation, maintenance and repair of the boiler. The floor in the furnace must be made of non-combustible materials - concrete screed, natural stone, paving stones. The furnace must be connected to the water supply for the operation of the water heater, and equipped with a sewer.
The area of the room for the boiler is 4 m 2, the height of the ceilings in the room is at least 2.5 m 2.
The outer door should be 80 cm wide.
The top of the chimney must be above the roof. The cross section of the chimney pipe must be larger than the diameter of the boiler outlet.
To supply power to the boiler room, an electrical panel with grounding must be equipped.
The gas line is brought into the room in advance. A separate valve must be installed for each gas appliance.
The walls of the boiler room are plastered - it is strictly forbidden to finish the walls with combustible materials (MDF, fiberboard, plastic).

It is forbidden to store flammable liquids and objects near the furnace and in the room itself. The foundation under (gas heating unit or gas water heating unit) should not freeze in winter, so its depth should be below the freezing level of the soil in this region. The air from the vent must be clean, that is, the chimney must be located far from the vent. The room or building in which the gas boiler is installed cannot be equipped for other purposes.

Rules for installing wall-mounted gas boilers in an apartment

Usually, in an apartment, a gas boiler is installed in the kitchen, since a gas main is already connected to it, there is water supply and sewerage. That is, a priori, all the requirements for the installation of gas equipment have already been met - it remains only to connect the boiler. This state of affairs automatically reduces the cost of laying utilities and energy. It is forbidden to install a gas boiler in rooms with high humidity - in the bathroom, laundry room, etc.

There are several additional requirements for wall-mounted boilers:

The wall or partition for hanging the boiler must be able to withstand it - do not hang the equipment on a drywall or other light partition.
If the wall is decorated with combustible materials (wallpaper, vinyl, plastic, MDF, fiberboard), then a 3 mm thick non-combustible material gasket is installed between the wall and the wall. In this case, the boiler must be fastened with special hardware, which provide a distance from the boiler body to the wall of at least 4-5 cm.
The minimum distance from the boiler to the ceiling and walls of the room is 0.5 meters. The distance from the boiler to the floor is 0.8 meters.

Before installation and start-up of gas equipment, all relevant documents must be obtained. The main condition for installing a boiler in a private house that runs on gas is that an agreement is first concluded on connecting a gas main, and a project for the installation of gas equipment and gasification of the house is drawn up. These documents are developed and approved by the gas supplier in the region.
