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 23) or service.

WARNING: Only a qualified service person should service and

repair heater. This includes maintenance requiring replacement or

alteration of components.

Figure 24 shows a correct pilot flame pattern.

Figure 25 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 25

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

pliance, page 19)

• see Troubleshooting pages 25 through 28.

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 26 shows a correct burner flame pattern. Figure 27 shows an incorrect burner flame

pattern. If burner flame pattern is incorrect then:

• turn heater off (see To Turn Off Gas to Appliance, page 19).

• see Troubleshooting pages 25 through 28.

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.
