BALANCED FLUE BOILERS
The Firebird boiler may be set for room sealed balanced flue operation, using a Firebird condensing
balanced flue kit. This kit does not draw combustion air from inside the room. It is drawn from
outside direct to the burner by the airpipe supplied with the boiler. Flue gases are expelled
through the same kit. However, if the boiler is installed in a compartment or small room, some
ventilation air is necessary to maintain acceptable temperature in boiler area.
Use of flue systems other then the matching Firebird
room sealed concentric flue, will invalidate warranty.
Balanced flue boiler in room (eg. kitchen) does not require individual ventilation.
