The thermostatic control used on these mod-
els differ 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 HI and LO.
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.
4. Keep control knob pressed in for 30 sec-
onds after lighting pilot. After 30 seconds,
release control knob. Follow step 8 under
Lighting Instructions, page 16 or 17.
