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.

Figure 14 - Correct Pilot

Flame Pattern

Figure 15 - Incorrect

Pilot Flame Pattern

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 panel of heater. View burner flame

through oval viewing hole on combustion chamber.

Thermocouple

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.
