INSPECTING BURNERS

Check pilot flame pattern and burner flame patterns often.

PILOT FLAME PATTERN

Figure 42 shows a correct pilot flame pattern. Figure 43 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.

If pilot flame pattern is incorrect, as shown in Figure 43

turn heater off (see To Turn Off Gas to Appliance, page 19 [Ther- mostat-Controlled Models] or page 21 [Remote-Ready Models])
