Shutting Off Heater
1. Turn control knob clockwise
to the OFF position.
2. Turn off all electric power to the ap-
pliance if service is to be performed.
Shutting Off Burner Only (pilot
stays lit)
Turn control knob clockwise
the PILOT position.
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
flow to the burner. This increases or de-
creases the burner flame height. At times
the room may exceed the set tempera-
ture. 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 heat
level between HI and LO.
Note: The thermostat sensing bulb mea-
sures the temperature of air near the
heater cabinet. This may not always agree
with room temperature (depending on
housing construction, installation loca-
Pilot Burner
tion, room size, open air temperatures,
etc.). Frequent use of your heater will let
you determine your own comfort levels.
