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 22) or service.

WARNING: Only a qualified service person should service and

repair heater. This includes maintenance requiring replacement or

alteration of components.

Figure 23 shows a correct pilot flame pattern.

Figure 24 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.

If pilot flame pattern is incorrect, as shown

in Figure 24

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

pliance, page 20)

• see Troubleshooting pages 24 through 27.

WARNING: If yellow tipping

occurs, your heater could pro-

duce increased levels of carbon

monoxide. If the burner flame

pattern shows yellow tipping,

follow instructions at bottom of

this page.

Figure 25 shows a correct burner flame pattern. Figure 26 shows an incorrect burner flame

pattern. If burner flame pattern is incorrect then:

• turn heater off (see To Turn Off Gas to Appliance, page 20).

• see Troubleshooting pages 24 through 27.

Air is drawn into the burner through the holes in the fitting at the entrance to the burner. These

holes may become blocked with dust or lint. Periodically inspect these holes for any blockage

and clean as necessary. Blocked air holes will create soot.
