INSPECTING HEATER
Check pilot ame pattern and burner ame pattern often.
PILOT FLAME PATTERN
Figure 20 shows a correct pilot ame pattern.
Figure 21 shows an incorrect pilot ame pattern. The incorrect pilot ame is not touching the thermocouple. This will cause
the thermocouple to cool. When the thermocouple cools, the heater will shut down.
If pilot ame pattern is incorrect, as shown in Figure 21
• turn heater off (see “To Turn Off Gas to Appliance,” page 21)
• see “Troubleshooting,” pages 24 through 26
BURNER FLAME PATTERN
Figure 22 shows a correct burner ame pattern. Figure 23 shows an incorrect burner ame pattern. The incorrect burner
ame pattern shows yellow tipping of the ame. It also shows the ame higher than one inch above the log.
Note: When using the heater the first time, the flame will be opaque orange/yellow for approximately one
hour until the log cures.

If yellow tipping occurs, your heater
could produce increased levels of
carbon monoxide. If burner flame
pattern shows yellow tipping, follow
instructions, bottom of this page.
WARNING
If pilot ame pattern is incorrect, as shown
in Figure 23,
• turn heater off (see “To Turn Off Gas
to Appliance,” page 21)
• see “Troubleshooting,” pages 24
through 26.
Do not mistake orange flames with
yellow tipping. Dirt or other fine
particles enter the heater and burn
causing brief patches of orange
flame.
