INSPECTING BURNERS
Check the pilot flame pattern and burner flame patterns often.
PILOT FLAME PATTERN
Figure 24 shows a correct pilot flame pattern. Figure 25 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 25:
• Turn the heater off (see TO TURN OFF GAS TO THE HEATER, page 23).
• See the TROUBLESHOOTING GUIDE,
