INSPECTING BURNERS

Check pilot flame pattern and burner flame patterns often.
PILOT FLAME PATTERN
Figure 19 shows a correct pilot flame pattern. Figure 20 shows an
incorrect pilot flame pattern. The incorrect pilot flame is not heating
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
• see Troubleshooting, page 17
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.

BURNER PRIMARY AIR HOLES
Air is drawn into the burner through the holes in the fitting at the
burner entrance. These holes may become blocked with dust or lint.
Periodically inspect these holes for any blockage and clean if needed.
Blocked air holes will create soot.
MAIN BURNER
Periodically inspect all burner flame holes with the heater running. All
slotted burner flame holes should be open with yellow flame present.
All round burner flame holes should be open with a small blue flame
present. Some burner flame holes may become blocked by debris or
rust, with no flame present. If so, turn off heater and let cool. Remove
blockage. Blocked burner flame holes will create soot.
