4.9. GAS Connection
Use the gas line connections only with CE certified components.
The PCH module is supplied complete with:
•
dual gas valve;
•
stabiliser and gas filter.
Al components are fitted inside the burner housing.
To complete the installation, as required by the current
regulations, the following components must be fitted:
•
anti-vibration joint;
•
gas valve.
---------------------------------------------------------------------------------
NOTE: AN
EN126 certified gas filter with filtration level lower
than or equal to 50 microns must be used, with no pressure
stabiliser, with great capacity, since the filter supplied as
standard, upstream of the gas valve, has a limited surface.
---------------------------------------------------------------------------------
----------------------------------------------------------------------------------
IMPORTANT: For proper maintenance, connect the PCH
module by means of a seal and swivel gasket.
----------------------------------------------------------------------------------
Avoid using threaded connections directly on the gas connection.
Current legislation allows a maximum pressure inside the
rooms, or thermal stations, of 40 mbar; higher pressure must
be reduced upstream of the boiler room or the site where the
PCH module is installed.

Supplying the gas circuit with pressure greater than
60mbar is strictly prohibited. Such pressures could cause
the valve to break.
