INSTALLATION
INSTRUCTIONS
GENERAL
The heater is designed for recessed installation in 2” X 4” (50mm
X 101mm) joist or larger ceiling section using the back box pro-
vided. The heater may also be surface mounted by using the
Surface Mounting Frame. The heater is intended to be con-
trolled by a single pole, wall mounted thermostat (ordered sepa-
rately). The heater may be wired with standard building wire
(60°C). (See Fan Delay Notice Above). Refer to specification
chart (see pg. 4) for correct supply voltage and wire size.
NOTE:
The optimum mounting height for this heater is 8’
(2440mm) from floor to bottom of back box. In any case do not
install closer than 6’ (1830mm) from the floor, or closer than 12”
(305mm) to adjacent walls.
INSTALLATION OF BACK BOX IN NEW CONSTRUC-
TION
NOTE:
If the finished ceiling surface is already up, follow
instructions for “INSTALLATION OF BACK BOX IN EXISTING
CONSTRUCTION”.
1. Determine which side of the back box is to be mounted
against a joist and bend the tabs at the rear corners out 90
degrees so that the back box will be square with the joist
after installation. (See Figure 1).
2. Remove one of the knockouts on socket side of the back box
and install a cable or conduit connector.
3. Position back box against side of joist and secure using
nails or screws as shown in Figure 1.
NOTE:
The back box must be installed with the front edge flush
with the finished surface.
4. Run power supply cable through the connector, leaving about
8” (203mm)of wire inside the box.
5. Run thermostat cable from wall thermostat to heater location
leaving at least 6” (153mm) of cable inside the box. (See
Fan Delay Notice.)
6. Connect the supply cable ground wire to green ground screw
provided.
NOTE:
Lead holes for a #8 sheet metal screw have been pro-
vided in the sides of the back box. After the finished ceiling has
been put up, drive a # 8(m4) sheet metal screw (recommended
1”) through the side of the box not mounted to the joist. This will
prevent the back box from pulling out when installing the heater
assembly. (See Figure 1)
Installation of Back Box in Existing Construction
1. Carefully mark and cut a hole measuring 9-3/8" (235mm)
wide by 11-1/8" (283mm) long. One edge of the hole must be
cut along the edge of a joist.
2. Proceed to No. 1 through 6 (Installation of Back Box in New
Construction).
To prevent a possible fire, injury to persons or damage to the
heater, adhere to the following:
1.
Disconnect all power coming to heater at main service
panel before wiring or servicing.
2. All wiring procedures and connections must be in accor-
dance with the National and Local Codes having jurisdic-
tion and the heater must be grounded.
3. Power supply must enter back box through the knockout
behind the disconnect switch.
4. Verify the power supply voltage coming to heater matches
the ratings as shown on the heater nameplate.
CAUTION:
ENERGIZING HEATER AT A VOLTAGE GREATER
THAN THE VOLTAGE PRINTED ON THE NAMEPLATE WILL
DAMAGE THE HEATER AND VOID THE WARRANTY AND
COULD CAUSE A FIRE.
5.
CAUTION
- High temperature, risk of fire, keep electrical
cords, drapery, furnishings, and other combustibles at least
3 feet (0.9 m) from front of heater. Do not install heater
behind doors, below towel racks, or in an area where it is
subject to being blocked by furniture, curtains or storage
materials. Hot air from the heater may damage certain fab-
rics and plastics.
6. To reduce the risk of fire, do not store or use gasoline or
other flammable vapors and liquids in the vicinity of the
heater.
7.
This heater is to be mounted only using back box. Back box
must be securely mounted to the building structure. Building
structure must be capable of supporting the heater and all
accessories (approximately 18 lbs (8.2 kg)).
8.
This heater is intended for ceiling installation only. DO NOT install
heater closer than 6 feet (1829 mm) from the floor. DO NOT install
closer than 12” (305 mm) to adjacent walls. DO NOT install in walls,
floor, or other locations.
9. Do not operate the heater without the grille installed.
10. Do not use this heater for dry out as the paint, plaster, saw-
dust and drywall sanding dust will permanently damage the
heater and must be kept out of the heater.
AN ELECTRICAL SHOCK, FIRE, OR WATER DAMAGE
COULD RESULT IF WIRING OR PIPING IS DAMAGED DUR-
ING CUTTING. MAKE SURE ALL WIRING AND PIPING ARE
CLEAR OF AREA BEFORE CUTTING.
