GAS Connection
Use the gas line connections only with CE certified components.
AH modules are 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;
•
gas filter.
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 AH
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 values must
be reduced before entering the boiler room or the site where
the AH module is installed.

During the installation, we recommend tightening the
external gas supply pipe nut without exceeding the
tightening torques shown below:
- Ø 3/4'':
150 Nm;
- Ø 1'':
200 Nm;
- Ø 1 1/2'':
300 Nm.
It is strictly prohibited to supply gas to the circuit with
pressure higher than 60 mbar. Such pressures could
cause the valve to break. If pressure is higher than 60mbar,
a pressure reducer must be installed at a distance of
at least 10 m and no pressure stabiliser must be fitted
between the pressure reducer and the unit, but leaving
the gas filter.
