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 21) 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 24, page 21, shows a correct pilot
ame pattern. Figure 25, page 21, shows an
incorrect pilot ame pattern. The incorrect pilot
ame is not touching the thermocouple. This
will cause the thermocouple to cool, which
shuts the heater o.
If pilot ame pattern is incorrect, as shown in
Figure 25, page 21,
• turn heater o (see To Turn O Gas to Ap-
pliance, page 19)
• see Troubleshooting pages 23 through 26.

occurs, your heater could pro-
duce increased levels of carbon
monoxide. If the burner ame
pattern shows yellow tipping,

yellow tipping. Dirt or other ne particles enter
the heater and burn causing brief patches of
