IMPORTANT INSTRUCTIONS
When using electrical appliances, basic precautions should always
be followed to reduce the risk of fire, 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 fire, or
damage to the heater.
8. To prevent a possible fire, 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 flammable
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 may
cause fire, electric shock or injury to persons.

Installation Instructions
WARNING: To reduce the risk of fire, do not store or use
gasoline or other flammable vapors or liquids in the vicinity of
the heater.
CAUTION: High temperature, risk of fire, 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 ¼” (6mm) from the end.
2. Cut a wall opening 18 ¼” (46cm) high by 14 ¼” (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 ¼” (8.3cm) minimum, measured
from finished 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
½ 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 finished wall surface, and secure box with four #10
Philips head wood screws, 1 ½” long (not provided). Insert
the wood screws through the inner set of flange 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 finished 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-fit 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 ¼” (6mm) from end.
2. Mount surface box to the wall using the four provided #8 ¾” Philips head wood screws, inserted through mounting
holes on the back side flanges. (For hard wall surfaces,
pre-drill mounting holes to prevent splitting wall surface.)
3. Install ½ 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 flanges.
5. Proceed with steps 7 through 11 inclusive in recessed
heater installation instructions.

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 comfort 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 sufficiently
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.
