WDV Series Gas Fireplace
The ames from the burner should be
visually checked as soon as the heater
is installed and periodically during normal
operation. In normal operation, at full
rate, and after operating for about 15 to
30 minutes, the ame should be yellow.
Figure 56
If the ame is blue and candle-like in
appearance, adjust glass or add more
glass over ports.
The type of installation, vent
system conguration, and wind effects
may cause the ame patterns to vary.
Keep the control compartment, stones and burner areas
surrounding the stones clean by vacuuming or brushing
at least twice a year. Make sure the burner porting, pilot
air opening and burner air opening are free of obstructions
at all times.
The ames from the pilot should be visually checked as
soon as the heater is installed and periodically during
normal operation.
Figure 55. The
pilot ame has three distinct ames, one engulng the
sensor, one engulng the thermopile, and the other reach-
ing to the main burner.
Inspect area around the injector. Remove any lint or foreign
material with a brush or vacuum.
