INSPECTING BURNERS

Check pilot flame pattern and burner flame pat-
terns often.
PILOT FLAME PATTERN
Figure 43 shows a correct pilot flame pattern. Figure
44 shows an incorrect pilot flame pattern. The incor-
rect 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 44
• turn heater off (see To Turn Off Gas to Appli-
ance, page 23 [Manually-Controlled Models]
or page 25 [Remote-Ready Models])
• see Troubleshooting, page 29
Note: The pilot flame on natural gas units will
have a slight curve, but flame should be blue and
have no yellow or orange color.
