The outlet pressure of the gas cock is obtained by completely loosening the
screw on the solenoid. The maximum pressure of the gas to the burner will be
equal to the nominal delivery pressure minus the head loss within the gas
valve.

Changing the Type of
Gas
The boiler can be converted to use either methane (natural) gas (G20) or
LPG (G30 - G31) by an Authorised Service Centre.
The operations that must be performed are the following:
1. Replace the jets on the main burner (see table in section 4);
2. Adjust the maximum and minimum thermal capacity values for the boiler
(see table in section 4);
3. Replace the gas rating plate;
4. Adjust the maximum thermal power setting;
