IMPORTANT INSTRUCTIONS

When using electrical appliances, basic precautions should always
be followed to reduce the risk of re, electric shock, and injury to
persons, including the following:

1. Read all instructions before using the heater.

2. The heater is hot when in use. To avoid burns, do not let bare

skin touch hot surfaces. The trim around the heater outlet be­comes hot during heater operation. Keep combustible materi­als, such as furniture, pillows, bedding, papers, clothes, and
curtains at least 3 ft (0.9 m) from the front of the unit and keep
them away from the sides and rear.

3. Extreme caution is necessary when any heater is used by or
near children or invalids and whenever the unit is left operating
and unattended.

4. Do not operate any heater after it malfunctions. Disconnect
power at the service panel and have the heater inspected by a
reputable electrician before reusing.

5. Do not use outdoors.

6. To disconnect the unit, turn the controls off, and then switch off
at main power supply panel.

7. Do not insert or allow foreign objects to enter any ventilation or
exhaust opening as this may cause an electric shock or re, or
damage to the heater.

8. To prevent a possible re, do not block air intake or exhaust in
any manner.

9. All electrical heaters have hot and arcing or sparking parts
inside. Do not use in areas where gasoline, paint, or ammable
liquids are used or stored.

10. Do not modify this heater. Use it only as described in this
manual. Any other use not recommended by the manufacturer

Installation Instructions

WARNING: To reduce the risk of re, do not store or use

gasoline or other ammable vapors or liquids in the vicinity of

the heater.

CAUTION: High temperature, risk of re, keep electrical

cords, drapery, furnishings, and other combustibles at
least 3 feet (0.9 m) from the front of the heater.

Recessed Installation

1. Allow 12” (30cm) of service cable for connecting to wall
box. Remove 6” (15cm) of the outer jacket and strip the
individual conductors 1/4” (6mm) from the end.

2. Cut a wall opening 18 1/4” (46cm) high by 14 1/4” (36cm)
wide (see Figure 1). Allow a minimum of 2” (5cm)
clearance around wall opening to accomodate heater
frame. Depth of wall opening must be 3 1/4” (8.3cm)
minimum, measured from nished wall surface.

3. Remove the screws securing heater assembly to the
wall box and separate. Keep all screws for heater
reassembly.

4. Remove rear knockout at top corner of wall box and
insert 1/2 cable connector. Bring service leads through
connector and secure end of cable to the connector.

5. For safety, each wall heater is provided with a grounding
screw located in the upper right corner of the wall

box. Connect ground lead and tighten screw for good
electrical connection.

6. Place wall box in wall opening so the welded side
brackets rest on nished wall surface, and secure box
with four #10 Philips head wood screws, 1 1/2” long (not
provided). Insert the wood screws through the inner
set of ange holes at both top and bottom. Alternate
holes are provided in sides of box for mounting to wood
framing. (If wall box is installed prior to application of
nished wall surface, set box to allow for wall thickness).

!

NOTE: When mounting wall box to hard wall surface,

predrill mounting and clearance holes to prevent splitting wall

surface.

7. Check nameplate on heater to make sure you are

connecting to the proper voltage. Remove any packing
material or debris from the heater assembly and wall
box. Then connect service leads.

8. Place heater assembly into the wall box. Check fan to
see that it turns freely, and service leads are clear of fan
area. Secure heater assembly to the wall box with four
sheet metal screws (provided).

9. Carefully position grille over heater assembly so that
protruding switch and thermostat shaft do not bind
against grille. Secure grille to heater assembly using
two Phillips head sheet metal screws (provided). Push
press-t thermostat knob on shaft.

10. Install the frame to the grille, securing its upper back
edge behind the lip on the top of the wall box, and its

lower edge with the single screw.

11. Energize heater circuit and test heater (see operating
instructions).

Surface Installation

1. Allow 30” (76cm) of service cable for connecting the
heater (see Figure 2). Remove all but 2” (5cm) of outer
jacket and strip individual conductors 1/4” (6mm) from

end.

2. Mount surface box to the wall using the four provided
#8 - 3/4” Philips head wood screws, inserted through
mounting holes on the back side anges. (For hard wall
surfaces, pre-drill mounting holes to prevent splitting wall
surface.)

3. Install 1/2 cable connector in hole on bottom of surface
box

near right side. Feed service leads through and secure
end of cable to the connector.

4. Remove the rear knockout on top of heater wall box near
right side and insert bushing (provided). Feed service
wires through bushing. Secure wall box to surface box
with four sheet metal screws (provided with the surface
box). Screws are inserted through the inside holes on
the anges.

5. Proceed with steps 7 through 11 inclusive in recessed
heater installation instructions.

Wiring

Two conductor non-metallic sheath cable with ground wire is
recommended for recessed installation of these heaters while
two conductor, metallic sheath cable (BX) is recommended
for surface installations. Use number 12 gauge wire for all
models. Each heater should be on an individual, properly

Operation

WARNING: This heater must be properly installed before

it is used.

These heaters are operated by an on/off switch and also a
temperature control with a knob.

1. Turn the switch ON. Remember there is a fan delay.

2. Set thermostat by turning the knob to desired room com-

fort level (clockwise to increase heat output). Once you
have determined the proper setting to provide the heat
level you prefer, you need not touch the knob again.

3. Turn the switch OFF to turn off heater. To reuse, simply
turn the switch ON - the temperature level you wish has
been previously set.

!

NOTE: This heater is equipped with a fan delay switch
which delays the fan operation until the heating grid has
heated sufciently to assure the circulation of only warm air.
This same switch permits the fan to operate after power to
the grid has been shut off by thermostat action, thus utilizing
all the heat remaining in the grid.

When the heater is shut down by turning the switch OFF,
power to both fan motor and element is diconnected and the
fan motor will not continue to operate.

WARNING: Should the OVERTEMP light come on,

disconnect power to the heater, turn the switch OFF or
turn down the thermostat fully counterclockwise and call
a licenced electrician. DO NOT USE HEATER UNTIL
PROBLEM IS DETERMINED AND FIXED.

Tamper Proof Models

The ON/OFF switch and the temperature regulating thermo­stat are recessed so that the continuous grille front panel can
be installed concealing both controls. The thermostat is op­erated by removing the front panel. The ON/OFF switch can
be operated by inserting a slender non metallic rod between
grille louvers and turning the switch ON or OFF.

Maintenance

WARNING: Disconnect power and heater has cooled
before attempting any maintenance or cleaning to reduce
the risk of re, electric shock or damage to persons.

!

NOTE: This heater should not be operated with an ac­cumulation of dust or dirt on or in the unit, as this can cause
a build up of heat and eventual damage. For this reason the
heater must be inspected regularly, depending upon condi­tions and at least at yearly intervals.

CAUTION: Before removing heater parts, open branch
service switch or remove fuses. These are located at the
distribution panel.

To clean, remove frame, grille and heater assembly. Remove
any dust and dirt from wall box and heater assembly with a
soft cloth or brush, then re-install heater assembly making
sure that the fan turns freely and service leads are away from
fan area. The frame and grille may be washed with a mild
detergent, however make sure they are thoroughly rinsed
and dried before re-installation.
