WARNING

Read Carefully - These instructions are written to help you

prevent difficulties that might arise during installation of
heaters. Studying the instructions first may save you
considerable time and money later. Observe the following
procedures, and cut your installation time to a minimum.

CAUTION - TO REDUCE RISK OF FIRE AND ELECTRIC
SHOCK:

1. Disconnect all power coming to heater at main service panel
before wiring or servicing.

2. All wiring must be in accordance with the National and Local
Electrical Codes and the heater must be grounded.

3. Verify the power supply voltage coming to heater matches the
ratings printed on the heater nameplate before energizing.

4. This heater is hot when in use. To avoid burns, do not let bare
skin touch hot surfaces.

5. Do not insert or allow foreign objects to enter any ventilation or
exhaust opening as this may cause an electric shock, fire, or
damage to the heater.

6. Do not block air intakes or exhaust in any manner. Keep
combustible materials, such as crates, drapes, etc., away
from heater. Do not install behind doors, furniture, towels, or
boxes.

7. A heater has hot and arcing or sparking parts inside. Do not use
it in areas where gasoline, paint, or flammable liquids are used
or stored.

8. Use this heater only as described in this manual. Any other use
not recommended by the manufacturer may cause fire, electric
shock, or injury to persons.

9. This heater is not approved for use in corrosive atmospheres
such as marine, green house, or chemical storage areas.

10. Heater must only be installed in a horizontal direction (motor &
thermostat to right) as shown in this manual. Do not install
sideways or upside down.

11. Heater must be installed with Back Box.

12. For wall mounting only. The following minimum clearances must
be maintained: Heater to floor - 4 in. (102 mm); Heater to any
adjacent wall - 6 in. (152 mm); heater to ceiling - 36 in. (915 mm).

13. When wiring, power supply must enter through knockouts in
right end of heater. Do not use the knockouts in left end of
heater.

14. Do not operate heater without grille installed.

15. Do not use heater for dry out. Paint, plaster, sawdust and dry­wall sanding dust will damage heater and must be kept out of
heater.

16. Grille and discharge air are hot when in use. Do not install or
use heater in any area where the airflow from heater may be
obstructed. Hot air may damage certain fabrics and plastics.
Always keep electrical cords, bedding, furniture, and other
combustibles away from heater.

NOTE: Heater should be controlled by either built-in thermostat or

remote wall thermostat. Models with “T2” suffix are equipped with
built-in thermostat.

This heater may be wired with standard building wiring (rated
minimum 60° C). Refer to Table 2 (Page 3) for appropriate wire
size for the heater to be used.

NOTE TO INSTALLER

The “IF” models do not include a backbox. The Backbox is
ordered separately. In the parts bag for “IF” models, there is a
white label that indicates multiple wattage and must be place in
the backbox on the bottom right-hand side. When making
wattage changes, the installer must circle the wattage on the
white label before installing the heat deck.

TO INSTALL BACK BOX IN NEW CONSTRUCTION -

WALL STUDS SPACING GREATER THAN 16” OC.

(REFER TO FIG. 2)

NOTE: Fig. 2 depicts the back box installed with the left side

adjoining stud. For a box with the right side adjoining a stud,
reverse the directions shown below.

1. Locate back box and back box support brackets (2). Back box
must be installed with mounting rails to the top (see Fig. 2B)

2. Determine which side of the back box will adjoin stud and
insert back box support bracket on that side with foot tab
directed towards center of back box. On the side of the back
box that will not adjoin stud, install back box support bracket
on that side with foot tab directed towards end of box and
secure to box with 3/8” long sheet metal screw (provided).

3. Determine which knockout in back box will be used for field
wiring and remove (see back box drawing pg. 1). Install
strain relief (field supplied).

4. Fish field wiring through strain relief leaving 6” of wire inside
box.

5. Insert back box assembly into wall, aligning rear of back box
with back side of stud (see Fig. 2C). The back box support
brackets should be resting on the sole plate of the stud wall
to insure proper spacing and leveling (see Fig. 2B).

6. Use two (2) wood screws or drywall screws or two (2) nails
(field supplied) to secure the side of the back box that adjoins
a stud. Use one (1) wood screw or drywall screw or one (1)
nail (field supplied) to secure the foot tab of the back box
support bracket (that is on the end opposite the stud) to the
sole plate (see Fig. 2B).

Figure 3

TO INSTALL BACK BOX (Model RBB)

IN NEW CONSTRUCTION - WALL STUDS 16” OC.

(REFER TO FIG. 1)

1. Locate back box (model RBB) and back box support
brackets (2). Back box must be installed with mounting rails
to the top (see Fig. 1B).

2. Install back box support brackets with foot tabs directed
towards the center of the back box as shown in Fig. 1A and
1B. It may be necessary to bend up slightly the tab on the
back box support bracket to allow insertion under the mount­ing lances on the bottom of the back box.

3. Determine which knockout in back box will be used for field
wiring and remove (see back box drawing pg.1). Install
strain relief (field supplied). See warning No. 13.

4. Fish field wiring through strain relief leaving 6” of wire inside
box.

5. Insert back box assembly into wall, aligning rear of back box
with back side of studs (see Fig. 1C). The back box support
brackets should be resting on the sole plate of the stud wall
to insure proper spacing and leveling (see Fig. 1B).

6. Using four (4) wood screws or drywall screws or four (4) nails
(field supplied), secure back box to studs (see Fig. 1B).
Back box support brackets can now be removed. If not
removed, secure to sole plate.

Figure 2A

Fig. 2B

Fig. 2C

TO INSTALL BACK BOX IN
EXISTING CONSTRUCTION

1. Locate wall studs to be sure that entire cut-out can be made
between studs. At least one side of the cut-out must be flush
with side of the stud. Bottom of cut-out must be 4” above
finished floor minimum. Make a cut-out in wall 14-1/2” wide
X 6-3/4” high (368mm X 171mm) (see Fig. 3).

2. Determine which knockout in back box will be used for field
wiring and remove (see back box drawing, pg.1). Install
strain relief (field supplied).

3. Fish field wiring through strain relief leaving 6” of wire inside
box.

4. Insert back box into cut-out. Rear of back box should be
flush with back of stud wall.

5. Using four (4) wood screws or drywall screws (field supplied)
or four (4) nails (field supplied), secure back box to studs
(see Fig. 1B). If wall studs are greater than 16”oc., use only
2 fasteners and on the opposite end of the back box drive a
1” sheet metal screw (provided) through hole in end cap.
This will draw the back box tight with drywall when grille is
installed. (See Fig. 4.)

TO INSTALL THERMOSTAT ASSEMBLY (RT2 only)

NOTE: Thermostat assembly should not be installed until after

the drywall phase of construction is complete. Dust from drywall
installation and joint compound can be harmful if it gets inside
thermostat assembly components.

1. The thermostat must be installed in right end of the heater.

2. Position thermostat above slot in right end of back box.

2

Push tab on thermostat bracket through slot in top, right
end of back box until the bracket locks in place. See Fig. 5.

3. If the thermostat is controlling more than one heater, the total
of all heater amperage ratings (Table 1) cannot exceed 25

amps at 120 volts AC thru 240 volts AC. Refer to Table

2 for correct wire, circuit breaker, or fuse sizing.

4. Connect one red and one black thermostat lead to power
wiring per wiring diagram (Fig. 6) using properly sized listed
wirenuts (provided).

5. Fold wires back into wiring compartment behind thermostat
to clear fan deck.

TO CHANGE WATTAGE OUTPUT

The chart shows the wattages available by model. Each heater
is factory wired for its maximum wattage. The last two columns
in the chart refer to the jumpers on the CLIP ‘n’ Fit

®

Board. To
change wattage, clip out Jumper 1 and/or Jumper 2 as shown in
the chart below. Completely remove jumpers by clipping at both
ends as close to the board as possible.

until fan deck stops (see Fig. 7).

3. Make wiring connections, attaching one red and one black
thermostat lead to two (2) black heater leads for 240V or to
black and white heater leads for 120V with wirenuts
(provided). Connect field ground lead to bare ground wire
with wirenut (provided). See Fig. 6.

4. Remove 1/2” knockout from grille and install grille using two
oval head screws. Push thermostat knob on thermostat
