Gas connection
Use the gas line connections only with EC certi
fi
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 certi
fi
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.
If the burner is not going to be used over a prolonged
period the gas supply valve must be closed.
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 150 Nm.
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
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.
