CLEANING AND MAINTENANCE
Turn off gas before servicing fireplace. It is
recommended that a qualified service technician
perform these check-ups at the beginning of
each heating season
BURNER, PILOT AND CONTROL
COMPARTMENT
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.
PILOT FLAME
The flames from the pilot should be visually checked as
soon as the heater is installed and periodically during
normal operation. The pilot flame must always be
present when the fireplace is in operation. Figure 57.
The pilot flame has three distinct flames, one engulfing
the sensor, one engulfing the thermopile, and the other
reaching to the main burner.
BURNER
Inspect area around the injector. Remove any lint or foreign
material with a brush or vacuum.
BURNER FLAME
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 58
If the flame is blue and candle-like in appearance, adjust
glass or add more glass over ports.
NOTE: The type of installation, vent system configuration,
and wind effects may cause the flame patterns to vary.
