THERMOSTATIC CONTROL OPERATION
The thermostat used on this heater senses the room tempera-
ture. At times the room may exceed the set temperature. If so,
the burner will shut off. The burner will cycle back on when
room temperature drops below the set temperature. The control
knob can be set to any comfort level between "HIGH" (5) and
"LOW"(1) (See Fig. 25).

OPERATION
INSPECTING BURNERS
Check pilot ame pattern daily when in use and at least yearly by a qualied service agency.
PILOT FLAME PATTERN
Fig. 26 shows a correct pilot ame pattern. Fig. 27 shows an incorrect pilot ame pattern. The incor-
rect pilot ame is not touching the thermocouple. This will cause the thermocouple to cool, which
shuts the heater off. If pilot ame pattern is incorrect:
• turn heater off (see “To Turn Off Gas to Appliance” on page 19)
• see Troubleshooting pages 23 through 26.
