5.5 Converting the boiler for different gas type
The conversion of a boiler from burning natural gas to
LPG, or vice versa, must be carried out exclusively by
professionally qualified personnel, registered in
accordance with current legislation.
Check that the gas supply pipe is suitable for the new
fuel type.
When converting from one gas type to another, simply change
the settings of the electric fan modulation board to those of the
new gas type:
• Open the control panel (see “6.3 Accessing the boiler”).
• Fit jumper P1 MAX as shown in figure 1:
o Pos. A – NATURAL GAS G20
o Pos. B – LPG G30/G31.
• Then set parameter 2 “Selecting the type of gas”
• Close the control panel and restart the appliance.
•
• Then set parameters 10 and 11 (see “Regulating the gas
pressure”).
N.B. The jumper must always be fitted regardless of the type of
gas being used. Removing the jumper will cause the fan to
malfunction.
