INSPECTING
BURNERS
Check pilot flame pattern and burner flame patterns often.
PILOT FLAME PATTERN
Figure 23 shows a correct pilot flame pattern. Figure 24 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 24
• turn heater off (see To Turn Off Gas to Appliance, page 21)
• see Troubleshooting, pages 23 through 26
