THERMOSTAT CONTROL OPERATION

The thermostatic control used on this model differs from standard ther-
mostats. Standard thermostats simply turn the burner on and off. The
thermostat used on this heater senses the room temperature. 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).
