H. Air Shutter Setting
This appliance has an adjustable air shutter (which con-
trols the primary air) 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 qualifi ed installer at in-
stallation.
To adjust air shutter, loosen the wing nut. Close air shutter
by pushing the air shutter forward. Care should be taken
when adjusting the air shutter so as not to cause the ap-
pliance to soot. If sooting occurs the air shutter will need
to be opened by pulling the air shutter forward.
