In many modern villages today there are no central 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 wide range, they can be divided by 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 for
A gas boiler must be installed, and then inspected by a gas service specialist. A professional will check whether all work has been carried out correctly, whether installation features have been 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 maintaining pressure within 1.8 atmospheres. You can find this indicator by looking at the equipment pressure gauge.
At this time, the 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 safety systems and automation, which involves the connection of electricity, then an electric current should be provided.
Installation: boiler room requirements
The gas boiler must be installed in a room that is equipped in accordance with the 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 should correspond to the thermal emission 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 m 3 . If the power increases to 60 kW, then the volume of the room needs to be increased to 13.5 m 3 . Whereas at 200 kW the volume of the room should be equal to 15 m 3 .
Recommendations of a specialist for choosing a boiler room
Installation of a gas boiler should be carried out in spacious rooms. The larger the area of the house, the more impressive the volume of the boiler room should be. The passport should find where the equipment should be installed - in the furnace or boiler room. This should be noted.
The modern market offers many new products, the installation of which is no longer presented with such strict rules. For example, gas heating boilers with closed combustion chambers are safe and do not require the preparation of a large space and the presence of windows and ventilation in the boiler room.
Air exchange recommendations
The connection of 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 optimum temperature it will be necessary to ensure the supply of 2.5 m 3 of gas per hour. For such a volume of fuel, 30 m 3 of air is needed. 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 health. If they are not taken out of the premises on time, then a person may die.
An important point is to ensure that the distance from the equipment surface to the wall, which should be 10 cm. This is true if the wall surface has a finish of non-combustible materials.
Installation requirements
The 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 so that it is naturally lit. For every 10 m 2 of the boiler room there should be 0.3 m 2 of window, this value is the minimum. The area of the hole for the influx of external air should be 8 cm 2 for each kilowatt of device power.
Wiring diagram
A gas boiler, the wiring diagram of which you must have studied before starting installation work, is installed in several stages. The chimney device acts as a final step. But first, the property owner should conclude a gas supply agreement. If we are talking about the simplest equipment, then it consists of a heat exchanger and a gas burner. It is necessary to connect gas and water to such a device, and the exhaust will be discharged into the chimney system.
Before installing the boiler, it is necessary to clean the walls of the inlet pipes of debris that may remain after the assembly of the equipment is completed. Install a filter and stop valves on the water supply pipes, which must be located before and after the filter. Next, a chimney is installed, certain requirements are imposed on this system. The gas boiler must contain an exhaust pipe, the diameter of which must comply with the requirements specified in the manual. The pipe should rise above the ridge of the roof by 0.5 m, it is better to use a steel cylindrical chimney, in which there is a hole for cleaning.
The master should check the traction, because the automation will not allow you to continue working if it is insufficient. A special squeegee and a steel pipe will allow the boiler to be inserted into the gas pipeline system. To perform these manipulations, resort to the help of specialists. The gas boiler must be connected to the power supply system and an automatic device protecting against overloads should be connected.
Conclusion
For a gas boiler, a pedestal is usually required, for this you can prepare a concrete screed. 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 monitored during installation using the level.
