OPERATION
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 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).
