INSTALLATION
The heater is designed for recessed installation in 2” x 4” (50
mm x 101 mm) stud or larger wall sections using the back box
provided. The heater may be wired with standard building wire
(60°C). Refer to “Specifications” and heater nameplate for
correct supply voltage and wire size.
NOTE: The optimum mounting height for this heater is 18” to 24”
(450 to 600 mm) from floor to bottom of back box. DO NOT
install closer than 12” (305 mm) from the floor.
Mounting Clearances
Wall Mounting Only:
a. Minimum twelve (12) inches (305 mm) to floor;
b. Minimum twelve (12) inches
(305 mm) to adjacent walls;
c. Minimum thirty six (36) inches
(915 mm) to ceiling.
Preparing Heater For Installation
1. Remove the junction box cover / heater assembly from the
back box by removing 8 screws. Set the screws aside since
they will be used to reattach the heater assembly to the back
box later.
NOTE: The junction box cover / heater assembly consists of two
parts. The upper part is referred to as the junction box cover.
The lower part is referred to as the heater assembly. (See
Figure 1).
2. Remove one of the knockouts in the side of the back box
and install appropriate cable clamp (not supplied).
Installation of Back Box in New Construction
NOTE: If the finished wall surface is already up, follow instruc-
tions for “Installation of Back Box in Finished Wall”.
1. In new construction without the finished wall in place, posi-
tion the back box against the side of stud allowing the side to
extend beyond the stud so it will be flush with the finished
wall surface. (You must know the thickness of the finished
wall when installing) Secure the box to the stud using two
screws (not included) as shown in Figure 2.
2. Run power supply cable through cable clamp (previously
installed) leaving approximately 6 inches (152 mm) of wire
TO PREVENT POSSIBLE DAMAGE TO POWER WIRING,
USE ONLY THE KNOCKOUTS PROVIDED IN BACK BOX.
TO PREVENT HAZARD OF FIRE OR ELECTRICAL SHOCK,
DO NOT INSTALL WITHOUT BACK BOX.
