I. Air Shutter Setting
This appliance has an adjustable air shutter (which con-
trols the primary air) factory set for the minimum vertical
vent run (see Figure 14.3). If your installation has more
than the minimum required vertical vent length, adjust-
ment of the air shutter may be necessary to obtain opti-
mal fl ame appearance. This should be adjusted by a
qualifi ed installer at the time of installation.
By pushing the air shutter handle towards the pilot, you will
be closing the air shutter. To adjust loosen the wing nut.
Care should be taken when adjusting the air shutter so as
not to cause the appliance to soot. If sooting occurs the air
shutter will need to be opened by pushing the handle away
from the pilot. When fi nished tighten wing nut.
NOTICE: If sooting occurs, provide more air by opening
the air shutter.
