INSPECTING BURNERS

Check pilot flame pattern and burner flame pat-
terns often.
PILOT FLAME PATTERN
Figure 39 shows a correct pilot flame pattern.
Figure 40 shows an incorrect pilot flame pattern.
The incorrect pilot flame is not properly heating
the thermocouple. When the thermocouple cools,
the heater will shut down.
If pilot flame pattern is incorrect, as shown in
Figure 40
• turn heater off (see To Turn Off Gas to Appli-
ance, page 21)
• see Troubleshooting, page 25
Note: The correct pilot flame on natural gas units
will have a slight curve, but flame should be blue
and have no yellow or orange color.
