INSPECTING PILOT AND BURNER FLAME

24

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.

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.
