boilers leave the factory specifically
prearranged for G20 gas or G30/G31. The G20 models can be
converted to function with G30/G31 using the "specific nozzle
kit" (optional) provided by
Sime
on request separately from the
boiler.
If changing the type of gas to be used, carry out the entire
"GAS
CONVERSION"
phase of the appliance.
Boiler connection to the gas mains must be carried out in full
compliance with installation Standards in force.
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.

WARNING
Once installation has been completed, check that
the joints are air tight as indicated in the installation
Standards.

CAUTION
It is recommended that the gas line has a suitable
filter.
