Warning
The gas supply pressure must be guaranteed during heater operation and not with the heater off.
The space heater is equipped with a gas valve that contains: a gas filter, a pressure regulator, a safety solenoid valve,
a working solenoid valve, a pressure stabilizer and pressure taps.
It is good practice for the installer to set up the supply line as follows:
11
9 10
10
9 11
Parts (9), (10) and (11) are available as accessories and are not supplied with the heater.
When the line has been connected:
• Bleed the gas supply pipe;
• Check that the gas pipe is sealed.
• Open the gas stopcock (10) and check the seal of all connections to the heater.
Warning
The space heater is set for a maximum supply pressure of 60 mbar.
CHECK THAT THE GAS SUPPLY PRESSURE IS NEVER MORE THAN 60 mbar.
If the supply pressure exceeds this value, the gas valve safety membrane may rupture and put the valve into a
permanent safety block (in this case the valve, which cannot be repaired, must be replaced).
5.4. PREPARATION OF THE GAS BURNER
The space heater is set up in the factory by the manufacturer for one of the operating categories in Table I or Table
II. An adhesive label applied to the gas valve casing will indicate this operating category and the supply pressure for
which the burner has been prepared and tested: that is to say the type of diffuser ring (3) and the gas valve adjustment.
