Features of installing wall-mounted gas equipment

It is worth noting that a wall-mounted double-circuit boiler is a self-sufficient system and the installation of such equipment and its connection to existing networks does not cause difficulties. In order to install and connect a gas boiler, the following components are used:

ball valves for cutting off water lines and heating circuits;
various surges;
coaxial chimney that comes with the boiler.

To ensure the protection of the boiler from various impurities, it is necessary to install a number of filter elements: gas, magnetic and coarse filter. Gas wall-mounted boilers are installed in the following sequence:

The Neva Lux boiler is installed on the wall using special strips that are included in the kit. To securely attach the mounting strips to the wall, it is best to use anchors.
Ball valves are installed at the inlet and outlet of the boiler of the DHW and heating circuits. This will facilitate further preventive maintenance of the unit.
Then comes the installation of all the necessary filters using suitable filters.
After this, you can begin installing the heating circuit and DHW, or make a connection to existing pipeline systems.

All gas connections and filter installation must be carried out by gas company employees who have permission for this type of work.

Advice! It is best to install the Neva Lux boiler in the kitchen or in another room of a private house where there is a ventilation hole.
