“FORCED/OPEN INSTALLATION” (TYPE B23P/ B53P)
Boiler gas vent flue (Ø 80)
The vent flue can be oriented in whatever direction is
most convenient for the room. In this configuration, a
Ø 60-80 mm adapter must be fitted in order to connect
the boiler to a Ø 80 mm vent pipe.
9
In this type of installation, comburent air is drawn
from inside the boiler room, which must therefore
have adequate ventilation.
9
Uninsulated flue pipes are potentially dangerous
and can cause burns.
9
Ensure that the flue gas vent pipe has a 1% slope
towards the boiler.
9
The boiler automatically adapts its ventilation sy-
stem to suit the type of installation and the length
of the flue.
