Gas supply
boilers leave the factory specifically prearranged for G20 gas
OF
or G30/G31. The G20 models can be converted to function with
G30/G31 using the "specific nozzle kit" (optional) provided by
Climit
on request separately from the boiler.
If changing the type of gas to be used, carry out the entire "GAS
phase of the appliance.
CONVERSION"
The boiler must be connected to the gas mains in full compliance
with the installation standards in force in the country where the
appliance will be used.
Before connecting the boiler to the gas mains, the user must
ensure that:
– the type of gas is correct for the appliance
– the pipes are clean
– the gas supply pipe is the same dimension as or greater than
that of the boiler fitting (G3/4") and with a load loss less than
or equal to that contemplated between the gas mains and the
boiler.
