J. Air Shutter Setting
This appliance has an adjustable air shutter (which controls
the primary air) that can be accessed under the valve com-
partment located under the
fi
rebox assembly (Figure 12.19).
The air shutter is factory set for the minimum vertical vent
run. If your installation has more than the minimum required
vertical vent length, adjustment of the air shutter may be
necessary to obtain optimal
fl
ame appearance.
This should
be adjusted by a quali
fi
ed installer at the time of instal-
lation.
In the event of soot accumulation inside your appliance, the
air shutter should be opened further. When the shutter ad-
justment handle is all the way
down
, the air shutter is in the
open position. When the shutter adjustment handle is all the
way
up
, the air shutter is in the fully closed position.
