HEATING LEVEL
WARNING: When running
heater, set control knob at LOW,
MED or HI locked positions.
Never set control knob between
locked positions. Poor combus-
tion and higher levels of carbon
monoxide may result.
CAUTION: Do not try to ad-
just heating levels by using the
equipment shutoff valve.
Turn thermostat control knob counterclock-
wise to the desired heating level. The
main burner should light. Set control knob
to any heat level between 1 and 5 (see
Figure 21).
TO TURN OFF GAS
TO APPLIANCE
1. Turn control knob clockwise to the
OFF position.
2. Turn off all electric power to the appliance
if service is to be performed.
3. Close equipment shutoff valve (see Figure
16, page 13).
THERMOSTAT CONTROL
OPERATION
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. 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. All
plaques will turn off and on.
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 location, room size,
open air temperatures, etc.) Frequent use of
your heater will let you determine your own
comfort levels.
