BURNER FLAME PATTERN
Figure 41 shows a correct burner flame
pattern. Figure 42 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.
NOTICE: Do not mistake orange
flames with yellow tipping. Dirt
or other fine particles enter the
fireplace and burn causing brief
patches of orange flame.
If burner flame pattern is incorrect, as shown
in Figure 42
• turn fireplace off (see To Turn Off Gas to
Appliance, page 19)
• see Troubleshooting, pages 22 through 24

PILOT FLAME PATTERN
Figure 39 shows a correct pilot flame pat-
tern. Figure 40 shows an incorrect pilot flame
pattern. The incorrect pilot flame is not touch-
ing the thermocouple. This will cause the
thermocouple to cool. When the thermo-
couple cools, the fireplace will shut down.
If pilot flame pattern is incorrect, as shown
in Figure 40
• turn fireplace off (see To Turn Off Gas to
Appliance, page 19)
• see Troubleshooting, pages 22 through 24
