BURNER FLAME PATTERN
Figure 20 shows a correct burner flame pattern. Figure 21 shows an incorrect
burner flame pattern. The incorrect burner flame pattern shows yellow tipping of
the flame. It also shows the flame higher than 1/2 the heat shield height.
If yellow tipping occurs, your heater could produce increased
levels of carbon monoxide. If burner flame pattern shows yellow
tipping, follow instructions at bottom of this page.
Do not mistake orange flames with yellow tipping. Dirt or other fine
particles enter the heater and burn causing brief patches of orange
flame.
