Fan Operation
The fan operates automatically - turn the knob on the
speed control to adjust to the desired speed. The fan
will turn on as the fireplace comes up to operating tem-
perature. After the unit has been turned off and the unit
cooled to below a useful heat output range the fan will
shut off automatically.
Flame Characteristics
It is important to periodically perform a visual check of
the pilot and burner flames. Compare them to Figure
39.
If the flame patterns appear abnormal, contact a quali-
fied service provider for service and adjustment.
Pilot Burner Adjustment
1. Adjust pilot screw to provide proper sized flame.
2. Leak test.
