Managing Heat Output

The heat output from the appliance may be controlled
by adjusting the main gas valve. Reference lighting
instructions on Page 28 and chart on Page 34 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 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.
