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.
BURNER

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.

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.
