FRONT BURNER FLAME PATTERN
Figure 25 shows correct front burner flame pattern. Figure 26 shows incorrect front
burner flame pattern. The incorrect burner flame pattern shows yellow tipping at
top of blue flame.
If yellow tipping occurs, your heater could produce increased
levels of carbon monoxide. If front burner flame pattern shows
yellow tipping, follow instructions at bottom of this page. Yellow
flame on rear burner is normal.
Do not mistake orange flames with yellow tipping. Dirt or other
fine particles are burned by heater, causing brief patches of
orange flame.
