INSPECTING
BURNERS
Check pilot flame pattern and burner flame
patterns often.
PILOT FLAME PATTERN
Figure 34 shows a correct pilot flame pattern.
Figure 35 shows an incorrect pilot flame
pattern. The incorrect pilot flame is not touch-
ing the thermocouple. This will cause the
therrnocouple to cool. When the thermo-
couple cools, the heater will shut down.
If pilot flame pattern is incorrect, as shown
in Figure 35
• turn heater off (see To Turn Off Gas to
Appliance, page 16)
• seeTroubleshooting, pagesl9through21

with the heater running, All slotted burner
flame holes should be open with yellow

should be open with a small blue flame
present. Some burner flame holes may be-
come blocked by debris or rust, with no
flame present. If so, turn off heater and let
cool. Either remove blockage or replace
burner. Blocked burner flame holes will
