CLEANING AND MAINTENANCE
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 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. See
Figure 61. The pilot flame has three distinct flames, one engulfing the
thermopile, one engulfing the thermocouple, 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 and slightly taller than the rear log. See Figure 62.
If the flame is blue and only in the center, turn off unit and
let cool. After unit is cool, remove logs and check to make
sure the back holes in the burner are not covered with rock
wool. If the back holes are clear, add more rock wool to the
center of the burner. Replace logs.
NOTE: The type of installation, vent system
con guration, and wind effects may cause the ame
patterns to vary.
