INSPECTING
BURNERS
Check pilot flame pattern and burner flame
patterns often.

PILOT FLAME PATTERN

Figure 40 shows a correct pilot flame pat-
tern. Figure 41 shows an incorrect pilot
flame pattern. The incorrect pilot flame is
not properly heating the thermocouple.
When the thermocouple cools, the heater
will shut down.
If pilot flame pattern is incorrect, as shown
in Figure 41.
• turn heater off (see To Turn Off Gas to
Appliance, page 19)

BURNER FLAME PATTERN

Figure 42 shows a correct burner flame
pattern. Figure 43 shows an incorrect burner
flame pattern. The incorrect burner flame
pattern shows yellow tipping of the flame. It
also shows the flame higher than one inch
above the log.
Note: When using the fireplace the first
time, the flame will be yellow for approxi-
mately one hour until the log cures.
WARNING: If yellow tipping
occurs, your fireplace could pro-
duce increased levels of carbon
monoxide. If burner flame pat-
tern shows yellow tipping, follow
instructions in column 3.
