Managing Heat Output
The heat output from the appliance may be controlled
by adjusting the main gas valve. Reference lighting
instructions on Page 27 and chart on Page 33 showing
inputs at all the settings.
The main gas valve may be adjusted anywhere be-
tween high and low to give the desired combination of
flame aesthetics and heat output.
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
temperature. 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
40.
If the flame patterns appear abnormal, contact a
qualified service provider for service and adjustment.
Pilot Burner Adjustment
