INSPECTING
BURNERS

Check pilot flame pattern and burner flame
patterns often.

PILOT FLAME PATTERN

(Remote-Ready Models)

Figure 31 shows a correct pilot flame pat-
tern. Figure 32 shows an incorrect pilot flame
pattern. The incorrect pilot flame is not heat-
ing the thermocouple. This will cause the
thermocouple to cool. When the thermo-
couple cools, the heater will shut down.

If pilot flame pattern is incorrect, as shown
in Figure 32

• turn heater off (see To Turn Off Gas to

Appliance, page 15)

• see Troubleshooting, pages 19 through 21

PILOT FLAME PATTERN

(Variable Manual-Control
Models)

Figure 33 shows a correct pilot flame pattern.
Figure 34 shows an incorrect pilot flame
pattern. The incorrect pilot flame is not
heathing the thermocouple. This will cause
the thermocouple to cool. When the thermo-
couple cools, the heater will shut down.

If pilot flame pattern is incorrect, as shown
in Figure 34

• turn heater off (see To Turn Off Gas to

Appliance, page 16)

• see Troubleshooting, pages 19 through 21

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. Either remove
blockage or replace burner. Blocked burner
flame holes will create soot.
