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 pres- ent when the fireplace is in operation. Figure 68. The pilot flame has three distinct flames, one engulfing the thermopile, one engulfing the thermocouple, and the other reaching to the main 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. Figure 69
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.
NOTE: The type of installation, vent system configuration, and wind effects may cause the flame patterns to vary.
