FRONT BURNER FLAME PATTERN

Figure 33 shows correct front burner flame pattern. Figure 34 shows incorrect front burner flame pattern. The incorrect burner flame pattern shows yellow tipping at top of blue flame.

WARNING: If yellow tipping occurs, your heater could pro- duce increased levels of carbon monoxide. If front burner flame pattern shows yellow tipping, fol- low instructions at bottom of this page. Yellow flame on rear burner is normal.

NOTICE: Do not mistake orange flames with yellow tipping. Dirt or other fine particles are burned by heater, causing brief patches of orange flame.
