Installation of Back Box in New Construction
(See Figure 1).
NOTE: If the finished wall surface is already up, follow instruc-
tions for “Installation of Back Box in Existing Construction”.
1. Place the back box between two 16" (406 mm) center-to-
center wall studs at the desired mounting height but no clos-
er than 12" (305 mm) to adjacent wall or floor.
NOTE: If wall studs are spaced greater than 16” (407 mm) on
center, additional framing supports may be necessary.
2. Align back box such that the bottom and sides will be flush
with finished wall surface (top flange of back box should pro-
trude approximately 1/2" (12.7 mm) from finished wall surface
(You must know the thickness of the finished wall when
installing).
3. Secure the back box in position with wood screws or nails as
shown in Figure 1.
4. Run a power supply cable into the knockout area in the upper
right hand corner of the back box (see Figure 1). All wiring
must be in accordance with National and Local Electrical
Codes. Refer to Specifications for correct wire size.
5. Remove disconnect switch bracket by loosening two screws
on the right side.
6. Install a cable clamp in the knockout in the top of the back
box.

panel before wiring or servicing.
2. All wiring procedures and connections must be in accor-
dance with the National and Local Codes having jurisdiction
and the heater must be grounded.
3. Verify the power supply voltage coming to heater matches
the ratings as shown on the heater nameplate.
