patterns often.

PILOT FLAME PATTERN

Figure 37 shows a correct pilot flame pattern. 
Figure 38 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 38

•  turn heater off (see 

To Turn Off Gas to Ap-

pliance

, page 20.

•  see 

Troubleshooting

, page 26

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.

FRONT BURNER FLAME PATTERN

Figure  39  shows  correct  front  burner  flame 

pattern.  Figure  40  shows  incorrect  front 

burner  flame  pattern.  The  incorrect  burner 
flame pattern shows yellow tipping at top of 
blue flame.

 WARNING: If yellow tipping 

occurs, your heater could pro

duce increased levels of carbon 

monoxide. If front burner flame 

pattern  shows  yellow  tipping, 

follow instructions at bottom of 

this page. Yellow flame on rear 

burner is normal.

NOTICE: Do not mistake orange 

flames with yellow tipping. Dirt 

or other fine particles are burned 

by heater, causing brief patches 

of orange flame.

If front burner flame pattern is incorrect, as 

shown in Figure 40

•  turn heater off (see
