WARNING: If yellow tipping occurs, your heater could pro- duce 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.
NOTICE: Do not mistake orange flames with yellow tipping. Dirt or other fine particles are burned by heater, causing brief patches of orange flame.
If front burner flame pattern is incorrect, as shown in Figure 29, page 17.
