Turn control knob counterclockwise
to the HIGH position. The
main burner should light. Set control
knob to any heat level between HIGH
and LOW. To turn control knob from
HIGH to a lower setting, press in the
control knob and turn counterclock-

Check pilot flame pattern and burner flame
pattern often.
PILOT FLAME PATTERN
Figure 17 shows a correct pilot flame pat-
tern. Figure 18 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 18
• turn heater off (see To Turn Off Gas to
Appliance, page 11)
• see Troubleshooting, pages 13 through 15
