Gas supply
MIA HE C10
boilers leave the factory prearranged for gas G20
and can also work with G30/G31 without the need for any type
of mechanical conversion. Simply select parameter "tS 0.3" (see
"Parameter setting and display") and set the type of gas to be
used.
If changing the type of gas to be used, carry out the entire appli-
ance "Gas conversion" phase.
The boiler must be connected to the gas mains in full com-
pliance 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.

WARNING
Once installation has been completed, check that
the joints are air tight as indicated in the installation
Standards.
m
CAUTION
It is recommended that the gas line has a suitable fil-
ter.
