CLEANING AND MAINTENANCE
BURNER, PILOT AND CONTROL COMPART-
MENT
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 ames from the pilot should be visually checked as
soon as the heater is installed and periodically during
normal operation. The pilot ame must always be pres-
ent when the replace is in operation. Figure 66. The
pilot ame has four distinct ames, one engulng the
thermopile, one engulng the sensor, and the other two
reaching to the main burners.
BURNER
Inspect area around the injector. Remove any lint or foreign
material with a brush or vacuum.
BURNER FLAME
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 and slightly taller than the rear log. Figure 67
If the ame 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.
