THERMOSTAT CONTROL OPERATION
The thermostatic control used on this
model differs from standard
thermostats. Standard thermostats
simply turn on and off the burner. 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 tempera-
ture drops below the set temperature.
The control knob can be set t o any
comfort level between HI and Low (5-1).
Note: The thermostat sensing bulb
measures the temperature of air near
the heater cabinet.This may not always
agree with room temperatur(depending
on housing construction, installation
location, room size, open air
temperatres,etc.) Frequent use of your
heater will let you determine your own
comfort levels.
