K. Air Shutter Setting
This appliance has an adjustable air shutter (which controls
the primary air mixture) that can be accessed from under the
valve compartment located under the fi rebox assembly (see
Figure 12.11). If your installation has more than the minimum
vertical vent length, adjustments to the air shutter may be re-
quired to obtain the optimal fl ame appearance.
A qualifi ed
installer should adjust this at the time of installation.
It takes 16 full turns of the shutter adjustment handle to move
the air shutter from fully open to fully closed. In the event
of soot accumulation inside your appliance, the air shut-
ter should be opened further. When the shutter adjustment
handle is all the way
down
, the air shutter is in the
closed
position. When the shutter adjustment handle is all the way
up
, the air shutter is in the fully
open
position.
