TECHNICAL CHARACTERISTICS
CHIMNEY CONNECTION CHARACTERISTICS
It is mandatory to ventilate the boiler room. The high or low air vent opening dimensions
depend on the appliance power and the boiler room size. Refer to the local regulations in force.
FLUE PIPE CONNECTION TYPES
It is mandatory to use ACV flue systems to connect the appliance.
B23 : Connection to an exhaust duct that discharges the combustion products outside the room
where it is installed, with the combustion air being drawn directly from the boiler room.
B23P: : Connection to a combustion product exhaust system designed to operate with positive pressure.
C53(x) : Connection to separate ducts for supplying combustion air and discharging combustion prod-
ucts; these ducts may end in zones with dierent pressure levels, but are not allowed to be
installed on opposite walls of the building.
