Gas is considered the most cost-effective fuel in terms of efficiency. Even if there is no gas line in the holiday village, many owners of country houses use gas-holders, which, from the point of view of economy, is often more profitable than using other types of fuel. In any case, you need to know the rules for connecting a gas boiler in a private house, which strictly regulate all the nuances of installation and operation of equipment.
In short, the installation of a gas boiler in a private house can be carried out by any person, but equipment commissioning - acceptance and testing should be carried out by specialists from the gas service, connecting a gas boiler to a private house and operating it without them permission is impossible.
It is safer to entrust the installation of gas equipment to qualified representatives of a specialized organization. Only they will be able to perform the necessary work correctly, in accordance with the requirements of the SNiP, and ensure the safe operation of the equipment. In addition, a competent specialist always works under a contract in which it is indicated who, when and what carried out the work.
Gas equipment manufacturers offer customers different types of heating boilers that use blue fuel. They are designed for heating any area and are divided by type of installation into floor and wall.
The first of them are powerful, reliable and durable "flagship models" designed for installation in homes with above-average meters. The general lack of such models is only one - they will have to equip a separate room.
Wall-mounted gas boilers are an excellent alternative for a small private house: they do not need a separate room - Such devices are compact and versatile. In addition, their installation does not impose increased conditions on the carrying capacity of the wall - only a layer of non-combustible material between the boiler and the base is required.
If the boiler capacity is more than 30 kW, then it must be installed in a separate room. All information on how to install a gas boiler in a private house is given in the norms of SNiP, where there are clear requirements for the arrangement of the boiler room for heating equipment operating by burning fuel.
The boiler room can be placed in the attic, in the basement (basement), or simply in a separate room of the house. An essential requirement is free passage to the room, sufficient illumination and arrangement of a hard base.
In addition, the installation of a gas boiler in a private house has the following requirements for a boiler house:
volume not less than 13.5 m³ for boilers with a capacity 30-60 kW and more than 15 m³ for models with higher productivity;
convenient access to equipment.
for an hour ventilation must provide three-time air exchange;
walls and floors are made of non-combustible material;
Important! Heating boilers should be located at least 0.5 m away from combustible surfaces. And the partitions comply with the fire resistance standard RE1 45, i.e. they must resist open fire for 45 minutes.
The advantages of a detached boiler house are increased safety, reduced noise level and the possibility of using the vacated space for other purposes. The disadvantage will be the rise in price of the heating system device, since it will be necessary to draw an additional insulated branch of the pipeline.
At the same time, such requirements to such boiler houses are as follows:
separate foundation ;
concreted base for the boiler;
forced ventilation , which should provide threefold air exchange within an hour;
Compliance with the requirements regarding sizes boiler rooms;
in one room it is allowed to install no more than heating devices;
doors to the street must open outwards;

wall surfaces and floors are made of non-combustible material;
there is a window with for daylight and emergency ventilation - the window opening area should be suitable for the volume of the room (0.03 m 2 per 1 m³);
chimney 43> if it is needed for the device to be installed (for wall-mounted appliances with a capacity of less than 30 kW, the output of a coaxial pipe through the wall is permitted).
A sewer pipe is also brought to the boiler so that water can be drained from the system when it is replaced.
The room where the gas boiler is located must meet the necessary requirements, and not only the width and length of the room is regulated according to the capacity of the equipment, but also the size to the ceiling, which must be at least 2 m.
A ventilation duct must be installed in the boiler room without fail, a hole with a cross section of at least 0.02 m 2 is provided for this.
The location of gas boilers corresponds to the installation conditions of the chimney. At the same time, the parameters of the latter (height, channel area) relative to the installed gas equipment must be strictly observed.
The size of the internal section of the pipe for smoke output is the same or slightly larger than that of device. According to NPB-98, inside the chimney hole, the air flow rate should be 15-20 m / s, and such draft can be provided with a chimney height of about 5 meters.
Important! You can not remove smoke into the duct provided for ventilation. In boiler rooms that have a standard hood, air exchange must take place due to the incoming flow outside the room and, in part, as a result of its penetration from adjacent rooms.
For proper installation of the unit, you must first study the regulatory documentation and the rules for performing these works. They talk about the features of the installation of gas appliances for the heating system.
What kind of boiler would not have to be installed, it is imperative that you meet the requirements of certain norms and rules, such as:
SNiP 41-01-2003 about heating, ventilation and air conditioning.
SNiP 42-01-2002 about the gas distribution system.
SNiP 21-01-97 about fire safety.
SNiP 2. 04. 08-87 about the structure of boiler houses.

For these conditions, to install a gas boiler in the house, you must first obtain a regulatory act, which gives permission to work on the connection of gas appliances. And for the acquisition of TU, an application must be submitted to the local gas service, which must be answered within a month.
It is important to know! Specifications are the official permission to carry out the installation of a gas appliance. Unauthorized installation of a gas heater without TU is illegal and unsafe for the homeowner.
After the development of the design documentation and receipt of the act with the permission to install the gas boiler, it is installed, which is carried out in several stages:
Preparing a solid foundation . A concrete screed is poured on the floor, or a sheet of metal is put. Install the boiler must be strictly parallel to the floor.
Connecting the chimney and checking the thrust.
Connection of pipes of the heating system . In this case, a fine filter must be installed, which is usually placed in the return pipe in front of the boiler. And on both sides of the filter element put valves with ball locks.
When installing a double-circuit gas boiler in a private house, it is necessary to connect it to the water pipe . It is desirable to make the inset of the supply pipe from above, and the outgoing highway - below.
Connection to the gas pipeline . This can only be done by a gas service specialist.
The installation of a gas boiler is clearly shown in the video:
This completes the most necessary work. Exceptions are boilers with a closed combustion chamber. These devices are equipped with electronic control, and their start-up is performed simultaneously with the filling of the system, because without creating a certain pressure in the expansion tank, the boiler will not work.

Preventive measures for the routine inspection of gas boilers include the following types of work :
Checking the taps of the external and internal gas pipeline (disassembly, lubrication).
Inspection of thermostats on floor boilers.
Flushing or replacing filter elements.
Inspection of nozzles , checking the tightness of the door, operation of the pilot light on floor-standing appliances.
Thrust control in the chimney.
Check in winter frost on the coaxial tube of wall boilers.
All components that have been subjected to wear during operation must be replaced.
Note! After finishing the repair and before starting the heating system, the gas service worker checks the tightness of all the connections in the line. Usually used for this soap solution.
Competent preventive inspection will not only increase the life of the equipment being operated, but also reduce gas consumption.
