Figure 42 - Incorrect Pilot Flame Pattern
Check pilot flame pattern and burner flame
pattern often.
PILOT FLAME PATTERN
Figure 41 shows a correct pilot flame pat-
tern. Figure 42 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 42
• turn fireplace off (see To Turn Off Gas to
Appliance, page 19)
•
see Troubleshooting, pages 23 through 25
BURNER FLAME PATTERN
Figure 43 shows a correct burner flame
pattern. Figure 44 shows an incorrect burner
flame pattern. The incorrect burner flame
pattern shows sporadic, irregular flame tip-
ping. It also shows the flame consistently
higher than one inch above the log.
Note:
When using the fireplace the first
time, the flame will be orange for approxi-
mately one hour until the log cures.
If burner flame pattern is incorrect, as shown
in Figure 44
• turn fireplace off (see To Turn Off Gas to
Appliance, page 19)
• see Troubleshooting, pages 23 through 25
