>3%
.
CAUTION
– The condensate outlet duct must be airtight, suitably
sized to that of the siphon and must not be restricted
at any point.
– The condensate outlet must be constructed in full
compliance of the National or Local regulations in
force.
– Before commissioning the appliance, fill the siphon
with water.
2.11 Gas supply
Brava Slim HE
boilers leave the factory prearranged for gas G20
(methane) and can also work with G31 (propane) without the need
for any type of mechanical conversion. Simply select parame-
ter ”03” (see “ Parameter setting and display ") and set the type
of gas to be used.
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 en-
sure 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.
DANGER
Once installation has been completed, check that the
joints are air tight as indicated in the installation Stand-
ards.
CAUTION
It is recommended that the gas line has a suitable filter.
