INSPECTING
BURNERS
Check pilot flame pattern and burner flame patterns often.
PILOT FLAME PATTERN
Figure 29 shows a correct pilot flame pattern. Figure 30 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 fireplace will shut down.

could produce increased levels of carbon monoxide. Follow instruc-
tions at bottom of this page. Yellow flame on rear burner is normal.
NOTICE
Do not mistake orange flames with yellow tipping. Dirt or other
fine particles are burned by fireplace, causing brief patches of
orange flame.
If front burner flame pattern is incorrect, as shown in Figure 32
• turn fireplace off (see To Turn Off Gas to Appliance, page 23 [Thermostat-
controlled models} or page 25 [Manually-controlled models])
