BURNER FLAME PATTERN
Figure 26 shows a correct burner ame pattern. Figure 27 shows an incorrect burner ame
pattern. If burner ame pattern is incorrect then:
• turn heater off (see To Turn Off Gas to Appliance, page 20).
• see Troubleshooting pages 24 through 27.
BURNER PRIMARY AIR HOLES
Air is drawn into the burner through the holes in the tting 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.

INSPECTING BURNERS
IMPORTANT: Owner’s should check pilot ame pattern and burner ame pattern often.
Incorrect ame patterns indicate the need for cleaning (see Care and Maintenance,
page 22) or service.
WARNING: Only a qualied service person should service and
repair heater. This includes maintenance requiring replacement or
alteration of components.
PILOT FLAME PATTERN
Figure 24 shows a correct pilot ame pattern.
Figure 25 shows an incorrect pilot ame pat-
tern. The incorrect pilot ame is not touching
the thermocouple. This will cause the ther-
mocouple to cool, which shuts the heater off.
If pilot ame pattern is incorrect, as shown
in Figure 25
• turn heater off (see To Turn Off Gas to Ap-
pliance, page 20)
• see Troubleshooting pages 24 through 27.
WARNING: If yellow tipping
occurs, your heater could pro-
duce increased levels of carbon
monoxide. If the burner ame
pattern shows yellow tipping,
follow instructions below.
Notice: Do not mistake orange ames with
yellow tipping. Dirt or other ne particles enter
the heater and burn causing brief patches of
orange ame.
