WDV Series Gas Fireplace
The flames 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 flame should be yellow.
Figure 582
If the flame is blue and candle-like in
appearance, adjust glass or add more
glass over ports.
The type of installation, vent
system configuration, and wind effects
may cause the flame 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 flames from the pilot should be visually checked as soon as the
heater is installed and periodically during normal operation.
Figure 51. The pilot flame has three distinct flames, one engulfing the
sensor, one engulfing the thermocouple, and the other reaching to the
main burner.
Inspect area around the injector. Remove any lint or foreign material
with a brush or vacuum.
