Installation of back box in new Construction

1. Mounting Back Box (see Figure 1).

a. Place the back box between two 16" (406 mm) center-

to-center wall studs at the desired mounting height but
no closer than 8" (203 mm) to adjacent wall or floor.

noTe:

If wall studs are spaced greater than 16” on center, addi-

tional framing supports may be necessary.

b. Align back box such that the bottom and sides will be

flush with finished wall surface (top flange of back box
should protrude approximately 1/2" (12.7 mm) from fin-
ished wall surface).

c. Secure the back box in position with wood screws or

nails as shown in Figure 1.

2. Power Supply Wiring (see Figure 1)

noTe:

Wire compartment volume - 119 in

(1950 cm

a. Run a power supply cable into the knockout area in the

upper right hand corner of the back box. All wiring must be
in accordance with National and Local Electrical Codes.
Refer to Specifications, page 1 for correct wire size.

b. Remove knockout in the top of the back box and install a

cable clamp.

c. Insert power supply cable through cable clamp, allowing at

least 6" (152 mm) of leads to extend inside the back box.

d. Ground the back box by connecting the supply ground

lead wire to the green ground screw located in the inside
top of the back box.

Installation of back box in existing Construction

1. Provide a wall opening 14-1/2" (362 mm) wide by 18-1/2"

(470 mm) high at the desired mounting height, but no closer
than 8" (203 mm) to adjacent wall or floor. (see Figure 2.)

noTe:

Locate so at least one side of opening is at wall stud.

This heater is to be mounted only using back box and may
be installed with the back box recessed or surface mounted
as described within this manual.

8. The following minimum clearances must be maintained:

Bottom of heater to floor - 8” (203 mm) - optimum height
is 18” to 24”.

Sides of heater to adjacent wall - 8” (203 mm) -
optimum minimum 12” (305 mm).

Top of heater to ceiling - 36” (915 mm).
