Firebird Enviromax Condensing Range
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 burner by airpipe supplied with 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.
 
Balanced flue boiler in room (eg.kitchen) does not require individual ventilation.
BALANCED - FLUE BOILERS IN COMPARTMENTS
Use of any equipment other then the matching Firebird low level roomsealed
concentric flue kit is not guaranteed for low level discharge and will probably
invalidate the warranty.
