CLEANING and MAINTENANCE
W
ARNING
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, logs and burner areas surrounding the logs
clean by vacuuming or brushing at least twice a year. Make sure the burner
porting, pilot air opening and burner air openings 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 26.
The pilot flame has
three distinct flames, one engulfing the thermopile, one engulfing the thermo-
couple 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 dur-
ing normal operation. In normal operation, at full rate,
and after operating for about 15 to 30 minutes, the
flame should be yellow and slightly taller than the rear
log.

NOTE: The type of installation, vent system con-
figuration and wind effects may cause the flame
patterns to vary.
