AIR SHUTTER ADJUSTMENT/FLAME
APPEARANCE:
THE ALLAGASH B-VENT GAS STOVE IS
SHIPPED FROM THE FACTORY EQUIPPED
AS A NATURAL GAS STOVE; THERE-
FORE, IT WILL BE NECESSARY WHEN
USING THE STOVEWITH PROPANE GAS
TO ADJUST THE AIR SHUTTER ON THE
BURNER TUBE TO ACHIEVE THE PROPER
GAS TO AIR MIX. See Figure 6.
The air shutter adjustment can also help achieve
the desired flame appearance. Generally, flame
appearance is a matter of preference, however
most consumers enjoy the warm yellowish flame.
Closing the air shutter - will generate very long
yellow flames resulting in soot. Sooting produces
black deposits on the logs, on the inside walls of
the appliance, and potentially on the exterior
termination cap.
Sooting is caused by incomplete combustion in
the flames and lack of combustion air entering
the air shutter opening.
Opening the air shutter - will generate a flame
that is blue and transparent, or an “anemic”
flame. This flame is generally more efficient but
not as pretty.
Jøtul recommends the following settings for the
Allagash B-Vent gas stove:
for use with propane 1/4” open
for use with natural 1/4” open
REMEMBER: Run the stove for a minimum of
15 to 20 minutes for an accurate representation
of the flame appearance- this should be done
before and between any air shutter adjustment.
