BURNER FLAME PATTERN

WARNING: If yellow tipping

occurs, your heater could pro-

duce increased levels of carbon

monoxide.

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.

Figure 24 shows a correct burner ame pat-

tern. Figure 25 shows an incorrect burner

ame pattern. The incorrect burner ame

pattern shows yellow tipping of the ame.

It also shows the ame higher than 1/2 the

glass panel height.

If burner ame pattern is incorrect, as shown

in Figure 25

• turn heater off (see To Turn Off Gas To

Appliance, page 16)

• see Troubleshooting, page 19

INSPECTING HEATER

Check pilot ame pattern and burner ame

pattern often.

PILOT FLAME PATTERN

Figure 22 shows a correct pilot ame pattern.

Figure 23 shows an incorrect pilot ame pat-

tern. The incorrect pilot ame is not touching

the thermocouple. This will cause the thermo-

couple to cool. When the thermocouple cools,

the heater will shut down.

If pilot ame pattern is incorrect, as shown

in Figure 23

• turn heater off (see To Turn Off Gas to Ap-

pliance, page 16)

• see Troubleshooting, page 19

Note: The pilot ame on natural gas units will

have a slight curve, but ame should be blue

and have no yellow or orange color.
