INSPECTING
BURNER
Check pilot flame pattern and burner flame
pattern often.
PILOT FLAME PATTERN
Figure 19 shows a correct pilot flame pat-
tern. Figure 20 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 20
• turn heater off (see To Turn Off Gas to
Appliance, page 12).
• see Troubleshooting, pages 14 through 16.
