THERMOSTAT 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
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 1 and 5.
