WARNING: If incorrect

could produce increased levels
of carbon monoxide.

ange flames with yellow tipping.
Dirt or other fine particles are
burned by heater, causing brief
patches of orange flame.
Check pilot flame pattern and burner flame
patterns often.
PILOT FLAME PATTERN
Figure 43
shows a correct pilot flame pattern.
Figure 44
shows an incorrect pilot flame pat
-
tern. The incorrect pilot flame is not touching
the thermocouple. This will cause the thermo-
couple to cool. When the thermocouple cools,
the heater will shut down.
If pilot flame pattern is incorrect, as shown
in
Figure 44
.
• turn heater off (see

pliance

NOTE
: The pilot flame on natural gas units will
have a slight curve, but flame should be blue
and have no yellow or orange color.
