In many modern villages today there are no centralized heating systems, hot water is not supplied to the houses, and this problem can be solved by installing a heating boiler. Manufacturers offer units in a large assortment, they can be divided according to the type of fuel used. However, gas boilers remain one of the most popular today, due to their high efficiency. This equipment will work without problems if the installation and installation, as well as the connection were carried out correctly.

What to look out for

The gas boiler must be installed and then inspected by a gas service specialist. A professional will check whether all the work was carried out correctly, whether the installation features are observed. If everything is correct, then the specialist will issue a conclusion that will serve as the basis for opening the valve. It will be important to pressure test the heating system, while the pressure must be maintained within 1.8 atmospheres. You can find this indicator by looking at the equipment pressure gauge.

At this timea person checks whether all connections and joints are tight. The system must be free of air. Do not mix water with antifreeze, and if the equipment uses security systems and automation that involves connecting electricity, then you should ensure the supply of electricity.

Installation: boiler room requirements

The gas boiler must be installed in a room that is equipped according to requirements. The boiler room should be located in a non-residential room, which can be a pantry, basement or attic. Do not install such a device in a toilet or bathroom.

The volume of the room must correspond to the heat dissipation of the boiler and additional types of equipment. This should include an expansion tank. Thus, if the total thermal power does not exceed 30 kW, then the room for such equipment should have a volume of 7.5 m3. If the power increases to 60 kW, then the volume of the room must be increased to 13.5 m3. Whereas at 200 kW the volume of the room should be equal to 15 m3.

Recommendations from a specialist in choosing a boiler room

Installation of a gas boiler should be carried out in spacious rooms. The larger the area of \u200b\u200bthe house, the more impressive in volume the boiler room should be. In the passport, you should find where the equipment should be installed - in the furnace or boiler room. You should pay attention to this.

Modern marketoffers a lot of new products, the installation of which is no longer subject to such strict rules. For example, gas fired boilers with closed combustion chambers are safe and do not require large space preparation and windows and ventilation in the boiler room.

Recommendations for air exchange

Connecting a gas boiler is necessarily accompanied by the installation of an air exchange system. If the power of the equipment is 23.3 kW, then for the optimal temperature it will be necessary to ensure the flow of 2.5 m3 of gas per hour. This amount of fuel requires 30 m3 of air. If it is not enough in the room, then you will encounter a problem that is expressed in incomplete combustion of gas. This will lead to inefficient use of fuel, and the combustion process will be accompanied by the release of substances harmful to human he alth. If they are not taken out of the premises in time, the person may die.

An important point is to ensure that the distance from the surface of the equipment to the wall is 10 cm. This is true if the wall surface is finished with non-combustible materials.

Installation requirements

Gas water boiler must be installed according to certain rules. They say that the width of the door in the room should be 80 cm, and the boiler itself should be installed in such a way that it is lit naturally. Every 10 m2the boiler room should account for 0.3 m2 windows, this value is the minimum. The outside air inlet area should be 8 cm2 for each kilowatt of unit power.

Connection diagram

A gas boiler, the connection diagram of which you must study before starting installation work, is installed in several stages. The final step is the chimney device. But first, the property owner should conclude a contract for the supply of gas. If we are talking about the simplest equipment, then it consists of a heat exchanger and a gas burner. Gas and water must be connected to such a device, and the exhaust will be discharged into the chimney system.

Before installing the boiler, it is necessary to thoroughly clean the walls of the inlet pipes from debris that may remain after the completion of the equipment assembly. A filter and shut-off valves should be installed on the water supply pipes, which should be located before and after the filter. Next, a chimney is installed, certain requirements are imposed on this system. The gas boiler must contain a flue gas pipe, the diameter of which must meet the requirements specified in the manual. The pipe should rise above the roof ridge by 0.5 m, it is better to use a steel cylindrical chimney for this, in which there is a hole for cleaning.

The master should check the draft, because the automation will not allow to continue working if it turns out to be insufficient. A special drive and a steel pipe will allow you to embed the boiler into the gas pipeline system. Forperforming these manipulations should resort to the help of specialists. The gas boiler must be connected to the power supply system and an automatic overload protection device must be connected.

Conclusion

For a gas boiler, a pedestal is usually required, for this a concrete screed can be prepared. If we are talking about a wooden floor, then it is necessary to lay galvanized sheet iron in it. The position of the device should be checked during installation using a level.
