INSTALLATION INSTRUCTIONS
Clearance Information
IMPORTANT NOTE: For efficient and safe operation, the
heater must have adequate airflow. Therefore, locate heater so
that it is not likely to be blocked or damaged and do not allow
anything to be placed against or near the front of heater. It is
recommended that at least 6 inches (152 mm) clearance be
maintained in front of the heater.
For safe and efficient operation, maintain at least the following
minimum clearances:
Bottom of Heater to Finished Floor:
- May be installed on floor. However, for best performance,
install bottom of heater approximately 3 inches (76 mm) off
floor.
Top of Heater to Bottom of Nearest Drapes or Window Sill
Above Heater:
- Minimum 6 inches (152 mm)
IMPORTANT NOTE: Certain fabrics and vinyl materials (such
as vinyl blinds) may become damaged by the heated air from
the heater and should not be installed above the heater.
Front of Heater to Full Length Drapes in Front of Heater:
- Minimum between bottom of drapes and floor – 2-1/2 inches
(64 mm)
- Minimum between top of drapes and ceiling – 1/2 inch (13
mm)
- Minimum between front of heater and nearest fold of drape –
3 inches (76 mm)
Mounting and Wiring
1. Locate on vertical wall with length of heater positioned
horizontally.
2. When selecting a mounting location, refer to the CLEAR-
ANCE INFORMATION for appropriate mounting limitations.
3. Remove front cover by removing screws at bottom of cover
and lifting cover out and up.
4. Select knockout through which electrical wiring must be
brought into heater. Wiring can enter from either end. See
Fig. 1. Remove junction box cover by removing two (2)
screws. Install strain relief leaving 6” (152mm) of wire inside
junction box.
5. Mount the rear panel assembly of the heater to the wall
using the 3/16” (4.7mm) diameter holes (screws and wall
anchors to be supplied by customer).
6. Make the proper connections following the wiring diagram
(Fig 2). Grounding conductor must be connected to green
ground wire. Replace junction box cover.
7. Install the front cover by hooking the top edge of the cover
over the top edge of rear panel and attaching the bottom lip of
the cover to the rear panel using screws removed in step 3.
TO REDUCE THE RISK OF FIRE AND ELECTRIC SHOCK OR
INJURY TO PERSONS, OBSERVE THE FOLLOWING:
1. Serious injury or death could result from electric shock.
Make sure electrical power supply circuit coming to heater
are disconnected at main disconnect or service panel
before installing this heater.
2. Wiring procedures and connections must be in accordance
with the National Electrical Code (NEC) and local codes.
Refer to Wiring Diagram on heater and Figure 2. Make sure
all electrical connections are tight to prevent possible over-
heating. Use Copper Supply Wire Only.
3. Verify the electrical power supply voltage matches the volt-
age rating as printed on the heater nameplate.
CAUTION - Never connect a heater to a voltage greater than
the nameplate voltage as this will damage the heater and
could cause a fire.
4. Do not install the heater against combustible low-density
cellulose fiberboard surfaces, against or below vinyl wall
coverings, or below any materials that may be damaged by
heat such as vinyl or plastic blinds, curtains, etc.
5. Do not install heater below an electrical convenience recep-
tacle (outlet).
6. CAUTION – Heater operates at high temperatures. Keep
electrical cords (including telephone and computer cables),
drapes, and other furnishings away from heater. For effi-
cient and safe operation, we recommend maintaining a min-
imum of 6 inches (152 mm) clearance in front of the heater
at all times. See Clearances Chart for minimum clearance
requirements.
7. To reduce the risk of fire, do not store or use gasoline or
other flammable vapors or liquids in the vicinity of the
heater.
8. Do not install heater upside down or in any position other
than as shown in this manual.
9. Do not recess heater in wall or install heater inside any type
enclosure as this will cause heater to overheat and could
create a hazard.
10. When mounting heater, use care when drilling mounting
holes and mounting heater to building structure to avoid
damaging internal heater components. Be sure to loosen
mounting screws ½ turn to allow for expansion and con-
traction.
11. Do not remove or bypass the safety limit control(s) as this
could allow heater to become a fire hazard – see heater
wiring diagram supplied with heater and Figure 2.
12. Do not allow object to be placed on top of heater as they
may be damaged or create a fire hazard.
13. Before energizing, make sure front cover is properly
attached to back housing and all screws are installed as
intended. Do not operate heater without front cover
installed.
14. This heater is not approved for use in hazardous or corro-
sive environments such as marine, green house, or chemi-
cal storage areas.
