Fan Noise
– Decibel ratings are 65 to 68 dB’s
– Check grill for loose screws
– Check fan blade balance to be sure that it is not making contact with fan shroud
– Check motor shaft bearings

Heat exchanger noise
– Check vent system, need 4 inch oval vent (bw) on top of unit before going to round pipe, no 90 degree elbows

– If over 2000 feet altitude unit has to be de rated

Can you add duct work
– Only factory supplied register kits are allowed refer to instructions

Cycles on and off frequently
– In cold environments, the unit may seem to cycle on and off because the fan only activates when there is enough heat to blow warm air. The burners will continue to run and build up more heat even when the fan is off.

Can I add duct work?
– only factory supplied register kits are allowed refer to instructions

Cycles on and off frequently
– In cold environments, the unit may seem to cycle on and off because the fan only activates when there is enough heat to blow warm air. The burners will continue to run and build up more heat even when the fan is off.
