12 - FACTORY OPTIONS AND ACCESSORIES
Gas connection
Use the gas line connections only with EC certifi ed components.
The PCH module is supplied complete with a dual gas valve, gas
stabiliser and fi lter. All components are fi tted inside the burner
housing.
To complete the installation, as required by current standards, an
anti-vibration joint and a gas valve must be fi tted.
Note: A EN216 certifi ed gas fi lter with fi ltration level lower or equal
to 50 micron must be used, with no pressure stabiliser, a wide
range gas fi lter must be used since the fi lter supplied as standard,
upstream of the gas valve, has a limited area.

Important: For a correct maintenance, connect the PCH module
by means of a seal and swivel gasket. Avoid using threaded
connected directly on the gas connection.
During the installation, tighten the external gas supply pipe but
without exceeding the tightening torque of 200 Nm (PCH080) or
300Nm (PCH130, PCH160 and PCH210).
PCH080
Gas supply: Ø 3/4''
Important: 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 are higher than 60 mbar, a pressure reducer must be
8
installed at least 10 m away and no pressure stabiliser must be
fi tted between the pressure reducer and the heater, but leaving
the gas fi lter.
If the burner is not going to be used over a prolonged
period the gas supply valve must be closed.
