PLAN THE INSTALLATION
This heater is designed for installation in an enclosed space such
as under a counter or kickspace to provide warm, gentle heat at the
floor level. Reread Safety Notes 3 through 8 for guidelines in planning the installation.
The Model 9114NT is factory wired for 240/208 V.A.C. operation. It
offers a choice of heat outputs and can be internally connected for
multiple wattages at different voltages shown in the table below.
VOLTS WATTS AMPS BTU/HR
240 1500 6.3 5120
208 1125 5.4 3840
120* 1500 12.5 5120
120* 750 6.3 2560
All ratings are 1-Phase, 60 Hertz.
*See “FIELD CONVERSION TO 120 V.A.C.” section.
FIELD CONVERSION TO 120 V.A.C.
Refer to FIGURE 1
If a 120 V.A.C. circuit is to be used, make wiring changes as follows:
1. Disconnect white wire from heater element terminal “2” and
connect it to terminal “4.” The heater will now operate at 120
V.A.C., 750W, 6.3A.
2. For 120 V.A.C, 1500W, 12.5A operation, add the short red
jumper wire (provided) between terminals “1” and “2”.
3. Remove alarm light wire leads from terminals “1” and “3” of the
high temperature limit. Remove white wire lead from limit terminal “1” and reconnect at limit terminal “3”. Secure wire leads
with wire tie so there is no interference with unit operation.
NOTE: Terminal numbers are marked on the side of the blower
housing, above the heater elements.

THERMOSTAT INSTALLATION
Refer to FIGURE 2
NOTE: The thermostat control circuit must be wired prior to the
wiring of the heater unit.
This heater may be thermostatically controlled by either a line
voltage wall-mounted thermostat (Model 86W), or an optional builtin thermostat accessory kit (Model 90). Model 90 thermostat kits
are designed for easy installation with this heater. Instructions for
installing thermostats are provided below and are also supplied
with each thermostat kit.
OPTIONAL LINE VOLTAGE WALL-MOUNT THERMOSTAT
1. Locate thermostat on an inside wall away from all drafts and
approximately 4-5 feet above the floor.
2. Route all wiring through the thermostat first and then to the
heater.
OPTIONAL (MODEL 90) UNIT-MOUNT THERMOSTAT
Refer to FIGURE 3
1. Remove the top cover from the heater.
2. Remove the 5/8” knockout located on the left side of the front
panel (use a screwdriver to remove the knockout). Also remove
the two plastic hole plugs (see illustration).
3. Install thermostat from back side of front panel and fasten in
place, from front, with two screws and washers provided (see
illustrations).
4. Attach temperature control knob by gently pushing it on to the
thermostat shaft. Flats on shaft and knob must line up for proper
installation (do not force control knob onto shaft).
5. Remove black wire from thermal fuse and attach it to thermostat terminal marked “4”.
6. Remove white wire from temperature limit terminal marked “1”
(Note: the other end of this wire is attached to incoming field
wiring) and attach it to the thermostat terminal marked “1”.
7. Attach black thermostat wire to thermal fuse and white thermostat wire to the temperature limited marked “3”.

INSTALL THE HEATER
Refer to FIGURE 4
1. Mark the intended mounting location in the base plate under
the counter or kickspace, and remove required material to provide for easy insertion and removal of the heater cabinet.
2. The unit will be secured in place with screws through the side
angle support brackets. Provide adequate material behind side
angle support for secure mounting.

WIRE THE UNIT
WARNING: Disconnect power at service entrance before wiring this product.
Refer to FIGURE 5
1. Run electrical power cable to installation location. Provide two
feet of slack to allow heater to be pulled out far enough to remove top cover for cleaning or servicing.
NOTE: It is recommended that flexible conduit be used for field
wiring to the unit to protect the wires from sharp objects or hazardous environments.
NOTE: Be sure supply voltage meets the equipment requirement.
Refer to the rating plate, unit wiring diagram and specification table.
Refer to FIGURE 6
2. Remove top cover for access to wiring box at rear of heater.
Refer to FIGURE 7
3. Remove one of the two knockouts and connect power cable to
heater using appropriate connector. Allow at least six inches of
wiring inside of wiring box.
4. Connect black to black, white to white and green (or bare wire)
to ground screw, as shown. Tuck wires down inside the wiring
box.
5. Replace top cover.
WARNING: Do not operate heater without top cover in place.
6. Slide heater into place and secure to mounting surface.
CHECK OPERATION
FIGURE 5
FIGURE 6
1. Turn thermostat counterclockwise to its lowest setting.
2. Turn on power to circuit at service entrance.
3. Turn thermostat clockwise. The heating element and fan should
come on. Set thermostat to desired temperature level. During
proper operation, the heater will cycle on and off periodically.
If heater does not come on:
1. Return the thermostat to lowest setting.
2. Shut off power at service entrance.
3. Remove the top cover, Check for proper line voltage and reinspect wiring connections. Reread installation procedure making sure all steps were followed.
4. Also check the thermal fuse. It may be open and need to be
replaced. Consult the service parts list for the part number of a
replacement fuse. Follow the procedure described in the last
paragraph of the warranty when ordering replacement parts.
MAINTENANCE
