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.
The flames from the pilot should be visually checked as
soon as the heater is installed and periodically during
normal operation.
Figure 64. The
pilot flame has three distinct flames, one engulfing the
thermopile, one engulfing the thermocouple or sensor, and
the other reaching to the main burner.
Inspect area around the injector. Remove any lint or foreign
material with a brush or vacuum.
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. Figure 65
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 rock wool is
placed correctly. Replace logs.
The type of installation, vent system
configuration, and wind effects may cause the
flame patterns to vary.
