Inspecting Pilot and Burner Flame

Check pilot flame pattern and burner flame pattern often.

PILOT FLAME PATTERN

Figure 14 shows a correct pilot flame pattern. Figure 15 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 15

•turn heater off (see To Turn Off Gas to Appliance, page 20)

•contact a qualified service person

BURNER FLAME PATTERN

Note: To view burner flame, remove lower front access panel of heater. View burner flame through oval viewing hole on combustion chamber.

Figure 16, page 22, shows a correct burner flame pattern. Figure 17, page 22, shows two incorrect burner flame patterns. The two incorrect flame patterns show high yellow flames and 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 22.

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.
