The thermostatic control used on these models
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 flow to the burner. This increases
or decreases the burner flame 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 1 and 5.
Note: The thermostat sensing bulb measures
the temperature of air near the heater cabinet.
This may not always agree with room tem-
perature (depending on housing construction,
installation location, room size, open air tem-
peratures, etc.). Frequent use of your heater will
let you determine your own comfort levels.
