INSPECTING
BURNER
Check pilot flame pattern and burner flame
pattern often.
PILOT FLAME PATTERN
Figure 25 shows a correct pilot flame pat-
tern. Figure 26 shows an incorrect pilot
flame pattern. The incorrect pilot flame is
not touching the thermocouple. This will
cause the thermocouple to cool. When the
thermocouple cools, the heater will shut
down.
If pilot flame pattern is incorrect, as shown
in Figure 26
• turn heater off (see To Turn Off Gas to
Appliance, page 14)
• see Troubleshooting, pages 16 through 18

BURNER FLAME PATTERN
Figure 27 shows a correct burner flame
pattern. Figure 28 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 heater the first time,
the flame will be yellow for approximately
one hour until the log cures.
NOTICE: Do not mistake orange
flames with yellow tipping. Dirt
or other fine particles enter the
heater and burn causing brief
patches of orange flame.
If burner flame pattern is incorrect, as shown
in Figure 28
• turn heater off (see To Turn Off Gas to
Appliance, page 14)
• see Troubleshooting, pages 16 through 18

tern shows yellow tipping, follow
