Flame Adjustment / Air Shutter
THE KATAHDIN GAS INSERT IS SHIPPED FROM THE
FACTORY EQUIPPED FOR USE WITH NATURAL GAS.
WHEN USING PROPANE, IT WILL BE NECESSARY TO
ADJUST THE AIR SHUTTER ON THE BURNER TUBE TO
ACHIEVE THE PROPER GAS TO AIR MIX. See fig. 15.
WARNING:
AIR SHUTTER ADJUSTMENTS SHOULD ONLY BE
PERFORMED BY A QUALIFIED PROFESSIONAL
SERVICE TECHNICIAN.
The air shutter adjustment can also help achieve
the desired flame appearance. Generally, flame appear-
ance is a matter of preference, however most consum-
ers enjoy the warm, yellowish flame.

the Air Shutter - Insufficient combustion
air will result in very long yellow flames that can
promote soot. Sooting produces black deposits on the
logs, on the inside walls of the appliance, and poten-
tially on the exterior termination cap.
Sooting is caused by incomplete combustion in the
flames and lack of combustion air entering the air
shutter opening.
