GAS CONVERSION

Conversion from the gas of one family to the gas of another family
can be done easily even when the boiler is already installed.
This operation must be carried out by professionally qualified
personnel. The boiler is designed to operate with methane gas
(G20) or LPG (G31) according to the product label. The boiler
can be transformed to LPG or to methane gas (G20) by means
of special kits.
For disassembly refer to instructions below:
ƒ disconnect the boiler from the electricity supply and turn off
the gas tap
ƒ remove the casing as explained in paragraph "4.6 CASING
REMOVAL"
ƒ release the instrument panel and rotate it forwards
ƒ unscrew the pipe nut from the gas valve and rotate the pipe
so as to have access to the gas nozzle (B) in the outlet fitting
ƒ remove the nozzle (B) and replace it with the one from the
kit
ƒ put the pipe of the gas valve back in place and screw the nut
ƒ reposition the previously removed components
ƒ power up the boiler and open the gas tap again.
Adjust the boiler as explained in paragraphs "5.18 Adjustments"
