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 25) or service.
WARNING: Only a qualied service person should service and
repair heater. This includes maintenance requiring replacement or
alteration of components.
PILOT FLAME PATTERN
Figure 26 shows a correct pilot ame pattern.
Figure 27 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 27
• turn heater off (see To Turn Off Gas to Ap-
pliance, page 19 or 21)
• see Troubleshooting pages 27 through 29.
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 at bottom of
this page.
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.

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.
