OPERATION
Continued
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.

with a three-prong, grounding
plug as shown in Figure 22. The
plug is your protection against
electrical shock. Plug it into a
standard, three-hole, grounded,
outlet. If cord needs replacing,
use only a cord with a three-
prong, grounding plug.
CAUTION: Label all wires
prior to disconnection when
servicing controls. Wiring errors
can cause improper and danger-
ous operation.
CAUTION: Do not plug power
cord into electrical outlet until
installation is complete.

WARNING: Always operate
manual control heaters at the
locked positions. Operation
between these positions may
create a possible health hazard
if used in a poorly ventilated
room. Read owner’s manual for
complete instructions.
CAUTION: Do not try to ad-
just heating levels by using the
equipment shutoff valve.
TO TURN OFF GAS
TO APPLIANCE
Shutting Off Heater
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 14).
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. The thermostat
adjusts the amount of gas ow to the burner.
This increases or decreases the burner ame
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. Selecting the 5 setting will
cause the burner to remain fully on without
modulating down in most cases.
