INSPECTING PILOT AND BURNER FLAME

Check pilot flame pattern and burner flame pattern often.

PILOT FLAME PATTERN

Figure 19 shows a correct pilot flame pattern. Figure 20 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching the thermocouple. This will prevent the thermocouple from getting hot, causing the heater to shut down.

BURNER FLAME PATTERN

Note: To view burner flame, look through front glass of heater.

Figure 21, page 25, shows a correct burner flame pattern. Figure 22, page 25, shows two incorrect burner flame patterns. The two incorrect flame patterns show ragged yellow flames and flames lifting off of burner.

WARNING

WARNING ICON

G 001

If ragged yellow flame occurs, your heater could produce increased levels of carbon monoxide. If burner flame is incorrect, follow instructions on page 25.

NOTICE

Do not mistake orange flames with yellow flame. Dirt or other fine dust particles enter the heater and burn causing brief patches of orange flame.
