THERMOSTAT CONTROL OPERATION
The thermostatic control used on this heater differs from standard thermostats. Standard thermostats simply
turn on and off the burner. The thermostat used on this heater senses the room temperature. The thermostat
adjusts the amount of gas ow to the burner. This increases or decreases the burner ame height. 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 heat level between HI and LO.
Note: The thermostat sensing bulb measures the temperature of air near the heater cabinet.
This may not always agree with room temperature (depending on housing construction,
installation location, room size, open air temperatures, etc.). Frequent use of your heater will
let you determine your own comfort levels.
