Check pilot flame pattern and burner flame patterns often.
PILOT FLAME PATTERN
Figure 26 shows a correct pilot flame pattern. Figure 27 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.

Flame Pattern
If pilot flame pattern is incorrect, as shown in Figure 27
• turn fireplace off (see To Turn Off Gas to Appliance, page 24)
• see Troubleshooting, pages 26 through 29
FRONT BURNER FLAME PATTERN
Figure 28 shows correct front burner flame pattern. Figure 29 shows incorrect front
burner flame pattern. The incorrect burner flame pattern shows yellow tipping at top of
blue flame.
If front burner flame pattern shows yellow tipping,
your fireplace could produce increased levels of
carbon monoxide. Follow instructions at bottom of
this page. Yellow flame on rear burner is normal.
Do not mistake orange flames with yellow tipping. Dirt
or other fine particles are burned by fireplace, causing
brief patches of orange flame.
