compliance of the National or Local regulations in

with water.
6.11 Gas supply
Vera HE
boilers leave the factory prearranged for gas G20 and
can also work with G31 without the need for any type of mechan-
ical conversion. Simply select parameter
"03"
(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.

CAUTION
If the gas supply is changed from G20 to G31, mark the
