Gas supply

Brava One HE ErP boilers leave the factory prearranged for gas
G20 and can also work with G230-G31 without the need for any
type of mechanical 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
appliance "COMMISSIONING" phase.
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.

the joints are air tight as indicated in the installation
