IMPORTANT: Owner's should check pilot flame pattern and burner flame pattern often.
Incorrect flame patterns indicate the need for cleaning (see Care and Maintenance,
page 20) or service.
WARNING: Only a qualified service person should service and
repair heater. This includes maintenance requiring replacement or
alteration of components.
Figure 22 - Correct Pilot Flame Pattern
Figure 22 shows a correct pilot flame pattern.
Figure 23 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.
Figure 24 - Correct Burner Flame Pattern
Figure 24 shows a correct burner flame pat-
tern. Figure 25 shows an incorrect burner
flame pattern. The incorrect burner flame
pattern shows yellow tipping of the flame. It
also shows the flame higher than 1/2 the heat
shield height.
WARNING: If yellow tip-
ping occurs, your heater could
produce increased levels of
carbon monoxide. If the burner
flame pattern shows yellow tip-
ping, follow instructions below.
