Pattern

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, fol-

low 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.

INSPECTING

BURNERS

Check pilot flame pattern and burner flame

patterns often.

PILOT FLAME PATTERN

Figure 24 shows a correct pilot flame pat-

tern. Figure 25 shows an incorrect pilot

flame pattern. The incorrect pilot flame is

not touching the thermocouple. This will

cause the thermocouple to cool. When the

thermocouple cools, the heater will shut

down.

If pilot flame pattern is incorrect, as shown

in Figure 25

• turn heater off (see To Turn Off Gas to

Appliance, page 15 [thermostat-con-

trolled models] or page 16 [manually-

controlled models])

• see Troubleshooting, pages 19 through 21
