INSPECTING BURNERS
IMPORTANT: Owner’s should check pilot flame pattern and burner flame pattern often.

Figure 33- Incorrect Burner Flame
Pattern with Control Knob Set to HI (5)
Figure 30 shows a correct pilot flame pattern.
Figure 31 shows an incorrect pilot flame pat-
tern. The incorrect pilot flame is not touching
the thermocouple. This will cause the ther-
mocouple to cool, which shuts the heater off.
If pilot flame pattern is incorrect, as shown
in Figure 31
• turn heater off (see
To Turn Off Gas to Ap-
pliance
, page 20)
• see
ODS Pilot
page 23.
Figure 31 shows a correct burner flame pat-
tern. Figure 32 shows an incorrect burner
flame pattern. If burner flame pattern is
incorrect then:
• turn heater off (see
To Turn Off Gas to Ap-
pliance
, page 18).
• see
Troubleshooting
pages 28 through 29
.
WARNING: If incorrect flame
pattern occurs, your heater
could produce increased lev
-
els of carbon monoxide. If the
burner flame pattern appears
excessive, see
Troubleshooting
pages 28 -29.
Notice:
Do not mistake orange flames with
yellow tipping. Dirt or other fine particles
enter the heater and burn causing brief
patches of orange flame.
BURNER PRIMARY AIR HOLES
Air is drawn into the burner through the holes
in the fitting at the entrance to the burner.
These holes may become blocked with dust
or lint. Periodically inspect these holes for any
blockage and clean as necessary. Blocked air
holes will create soot.
