Inspecting Burners - Superior BGE18NR Operation Instructions Manual

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 pat-
tern. The incorrect pilot flame is not touching
the thermocouple. This will cause the thermo-
couple 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 Ap-
pliance, page 25
• 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.
