Figure 25 shows a correct burner flame pattern. Figure 26 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.

particles enter the fireplace and burn causing brief patches of
orange flame.
If burner flame pattern is incorrect, as shown in Figure 26©20
• turn fireplace off (see To Turn Off Gas to Appliance, page 21).
