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
¿
rebox assembly (see
Figure 12.7). If your installation has more than the minimum
vertical vent length, adjustments to the air shutter may be re-
quired to obtain the optimal
À
ame appearance.
A quali
¿
ed
installer should adjust this at the time of installation.
It takes sixteen 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
shutter should be opened further. When the shutter adjust-
ment 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.
