BURNER FLAME PATTERN

Figure 33 shows a correct burner flame pattern. Figure 34 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.

WARNING: If yellow tipping occurs, your fireplace could pro- duce increased levels of carbon monoxide. If burner flame pattern shows yellow tipping, follow in- structions at bottom of this page.

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 34

•turn fireplace off (seeTo Turn Off Gas to Appliance, page 18)
