INSPECTING PILOT AND BURNER FLAME
Check pilot flame pattern and burner flame pattern often.
PILOT FLAME PATTERN
Figure 18 shows a correct pilot flame pattern. Figure 19 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.

If pilot flame pattern is incorrect, as shown in Figure 19
•turn heater off (see To Turn Off Gas to Appliance, page 22)
•contact a qualified service person
BURNER FLAME PATTERN
Note: To view burner flame, look through front glass of heater.
Figure 20, page 24 shows a correct burner flame pattern. Figure 21, page 24 shows two incorrect burner flame patterns. One incorrect flame pattern shows high yellow flames and the other shows flames lifting off of burner.
WARNING
If high yellow flame occurs, your heater could produce increased levels of carbon monoxide. If burner flame is incorrect, follow instructions on page 24.
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.
