GAS CONVERSION

GAS CONVERSION

8.1  Warnings

The operations to adapt the boil-

er to the type of gas available 

must be carried out by an autho-

rised service centre.

The components used for adapting to the 

type of gas available must only be original 

spare parts.

For instructions regarding calibrating the 

boiler gas valve, refer to section "CHECK-

ING THE GAS SETTING" on page 48.

8.2  Gas operations and setting

Check that the gas cock mount-

ed on the gas piping to the boil-

er is closed and that the unit is 

not powered.

•  Remove the front and side panels as 

shown in section "Maintenance" on page 

55.

•  Remove the movable wall from the sealed 

chamber.

•  Remove the front panel from the combus-

tion chamber and the burner in Figure 8.1.

•  Convert the type of gas by correctly re-

placing the burner nozzles and gaskets.

•  Reassemble the burner Figure 8.1, the 

front combustion chamber panel and the 

movable wall of the sealed chamber.

•  Restore electric power to the boiler.

The boiler is factory set to operate with 

natural gas (G20).

To set boiler operation to 

LPG gas (G31)

carry out the following settings:

• 

Enter  “programming  mode”  by  holding 

down buttons 17 and 18 for 5 seconds at 

the same time (Figure 8.2). The code 

P00

 

appears on the display, indicating entry 

into “parameter P00” (Figure 8.3).
