INSPECTING

BURNER

Check pilot flame pattern and burner flame pattern often.

PILOT FLAME PATTERN

Figure 17 shows a correct pilot flame pat- tern. Figure 18 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching the thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down.

BURNER FLAME PATTERN

Figure 19 shows a correct burner flame pattern. Figure 20 shows an incorrect burner flame pattern. The incorrect burner flame pattern shows yellow tipping of the flame. It also shows the flame higher than 1/2 the heat shield height.

WARNING: If yellow tipping occurs, your heater could pro- duce increased levels of carbon monoxide. If burner flame pat- tern shows yellow tipping, follow instructions at bottom of this page.

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

If burner flame pattern is incorrect, as shown in Figure 20

•turn heater off (see To Turn Off Gas to Appliance, page 10)
