Boiler room - what should it be

The room in which the boiler will be mounted must meet certain requirements. Otherwise it can lead to fatal consequences. Gas, as you know, is explosive, so jokes with it are bad.

So, consider the basic provisions that apply to the installation of boiler equipment:

If the boiler has a capacity of up to 150 kW, then its installation is possible in any non-residential area of the house, for example, a bathroom, bathroom, kitchen.
Boiler power from 150 kW and more limited in the choice of location. Allowed space for installation on the basement or ground floor.
If the installation location is a kitchen, then for 1 kW of its capacity should be 0.2 m³.
In case of gas leakage, there must be an instrument in the room to shut off the gas supply.
After installing the gas boiler, all major components should be provided with sufficient access for maintenance.
As for the walls of the room, they must have a fire resistance level of up to 45 minutes.
There are also requirements for the cross section of the grille for ventilation. Take calculations for 1 kW of power 8 cm².

Separate requirements are also imposed on the chimney system:

The diameter of the chimney must correspond to the specified parameter in the boiler data sheet.
The pipe must be 0.5 meters higher than the ridge.
The chimney should be no more than 25.
Admissible up to 3 bends.
To clean the chimney must have special holes.
The diameter of the chimney should be equal to or larger from the chimney opening.

At a height of not less than 800 mm from the floor.
There should be free space under the boiler.
Under the boiler on the floor is recommended to lay a metal sheet.

These documents are developed by the gas supplying organization. In the course of receiving this documentation, you may be required to have a package of documents, which include the fact that you own this living space.

Features of the installation of a floor boiler

Floor boiler has a fairly large weight. Therefore, the first step is to prepare the surface where the wall-mounted boiler will stand. This includes the following:

The screed is poured on the floor. The floor should be treated with non-combustible material. Ensure that the surface is perfectly flat.
It is also advisable to cover walls with non-combustible material. Otherwise, the boiler cannot be moved close to the wall. It will be necessary to maintain a distance of up to 10 cm.

When all preparations are completed, installation of auxiliary equipment is carried out. This includes:

Expansion tank.
Collector.
Hydraulic strap.
Boiler, etc.

Installation is much easier when there is a project that shows all the installation sites. On it, you mark the walls, and then make holes for fasteners. Also, the installed equipment at this stage is recommended to be connected to the pipeline going to radiators or with heated floors.

If the boiler is already installed, it may be difficult to connect the equipment to the pipes. For this reason, it is better to carry out all these works before installing the boiler.

As for the installation of the floor-standing boiler in the house, first of all it is necessary to wind in it the pipes and adapters, which are connected to the pipeline. Adapters can be of different diameter. For example, if the system is with natural circulation, then thick pipes are supplied to the boiler. If the forced circulation, the pipe and, accordingly, adapters will be of small diameter.

Having moved the boiler to the prepared place, it should be connected to the chimney. Next, connect the security group and connect to the rest of the strapping.

Features of installation of a wall boiler

In most cases, the boilers in the apartment are mounted on the mounting bar. It should be fixed to the wall at the desired height. Depending on the wall decoration, it may be necessary to fix non-combustible material, up to 3 mm thick. Also consider the fact that the boiler should be hung at a distance of at least 20 cm from other equipment.

Modern wall mounted boilers have a lower connection to the heating and water supply system. Therefore, after fixing the boiler to the wall, the boiler is strapped.

Connection to the gas pipeline

After installing the boiler, it is also necessary to connect the gas pipeline. This stage of work should be done carefully, because it is not worth joking with gas. The connection includes the installation of a filter and valve, which, if necessary, can shut off the gas supply. Next, connect a special gas hose. But in no case should you install a rubber hose. After a while, it will crack. To seal the thread used paronitovye gaskets. After tightening the nut of the hose, be sure to check it for gas.
