Gas supply conversion
The boiler comes ready for use with methane
gas (G20), but can be converted to work with
LPG (G30/G31) using the conversion kit pro-
vided and the LPG gas valve contained in the
relevant kit. Conversion must be performed by
the manufacturer's Technical Assistance
Service. The boiler can be converted even
after installation. To do so, proceed as follows.
REPLACING THE NOZZLES
- Remove the front panel from the casing.
- Unscrew the two nozzles from the methane
burner and replace them with the LPG noz-
zles, using the aluminium seals provided in
the kit (fig. 3.6).
