Fuel Connections; Flue Gas Outlet And Combustion Air Intake - Beretta POWER PLUS Installation Instruction

Fuel Connections

The POWER PLUS Boiler must be connected to the
natural gas or LPG supply in compliance with the rele-
vant standards in force.
Before making the connections, check that:
- the type of gas is the same that the appliance is set
for
- the pipes are thoroughly clean
- the gas supply pipes are the same size or larger than
the fitting on the boiler (3/4"), with a pressure drop that
is less than the pressure drop between the gas supply
and the appliance.

Flue Gas Outlet and Combustion Air Intake

The flue and the fitting to the flue must be made in com-
pliance with the standards and the legislation in force, as
well as with local regulations.
The pipes used must be rigid and resistant to temperatu-
re, condensate and mechanical stress, and airtight.

ger.
When installation is completed, check that the joints are
all tight, as required by the installation standards.
A suitable filter should be installed on the gas line.
