MANUAL LIGHTING PROCEDURE
THERMOSTATIC CONTROL OPERATION
The thermostatic control used on this model
differs from standard thermostats. Standard
thermostats simply turn the burner on and off.
The thermostat used on this heater senses the
room temperature. At times the room may ex-
ceed the set temperature. If so, the burner will
shut off. The burner will cycle back on when
room temperature drops below the set tem-
perature. The control knob can be set to any
comfort level between HIGH (5) and LOW (1).
Note: The thermostat sensing bulb measures
the temperature depending on housing con-
struction.
