INSPECTING HEATER

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 ther-

mocouple to cool, which shuts the heater off.

If pilot ame pattern is incorrect, as shown

in Figure 23

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

pliance, page 19 or 20)

• see Troubleshooting pages 23 through 25.

WARNING: If yellow tipping

occurs, your heater could pro-

duce increased levels of carbon

monoxide. If the burner ame

pattern shows yellow tipping,

follow instructions below.

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 22) or service.

WARNING: Only a qualied service person should service and

repair heater. This includes maintenance requiring replacement or

alteration of components.

PILOT FLAME PATTERN

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.

BURNER FLAME PATTERN

Figure 23 shows a correct burner ame pat-

tern. Figure 24 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 heat

shield height.

If burner ame pattern is incorrect, as shown

in Figure 24

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

pliance, page 19 or 20)

• see Troubleshooting pages 23 through 25.
