IMPORTANT INSTRUCTIONS

When using electrical appliances, basic precautions should al-

ways 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 ex-
haust 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 manufac-

turer may cause re, electric shock or injury to persons.

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.

This heater is designed for permanent installation only. Care
should be taken to install according to the following instruc­tions. All required clearances should be maintained. In addi­tion all electrical wiring and connections should comply with
local electrical codes.

!

NOTE: It is extremely important to read all information la­bels. Care must be taken to ensure that the heater is rated the
same voltage as the electrical supply wires. Failure to do so
could result in unsafe heater operation as well as damage to the
unit. If replacing an existing heater, check the labels of the old
heater to ensure the voltage of the new heater is compatible.

All units should be controlled by means of a regulating ther­mostat. Certain models only are provided with built in ther­mostats. Check the Model Key Information section for veri-

cation. Wall thermostats should comply with the voltage and

wattage of all heaters on the circuit.

All installations require the following components:

1) Recess Box (Model 1011650100)

2) Heater Assembly (See nameplate Label)

3) Grille

An optional Surface Mount Box is available for installations
that are not recessed in wall cavity.

Step 1 – Placement

All units are designed for placement in either interior or ex­terior walls. Care should be taken to provide a minimum of

8" clearance from oors, ceilings and adjacent walls. Once
installed, the airow through the heater should not be blocked

in any way. Maintain 3’ (91.4cm) clearance of objects from the
front of unit. Maintain a spacing of 3’ (91.4cm) between heat­ers in order to prevent re-circulation of heated air. Insulation
surrounding the back and sides of the recess mount box will
not affect performance. Ensure insulation is rated for tempera­tures up to 185°F (85°C).

!

NOTE: Certain ooring and wall covering materials (par-
ticularly those incorporating clear vinyl materials tend to distort
at temperatures in the vicinity of 140°F (60°C). Material shall
be checked prior to installation to determine if discoloration

will occur. Units are not approved for placement in oors or

ceilings. Do not install in any area where combustible vapors,

gases, dusts or liquids are present. Fire or explosion may oc­cur.

Step 2 – Mounting The Recess Box

Determine the desired orientation of unit. Provide an opening
in wall 14 ¼” x 8 1/8" x 3" (36.2cm x 20.6cm x 7.6cm) deep,
minimum. Care should be taken to install the recess box in the
correct orientation to accommodate grille. Note the position

of the electrical entry knockouts and orient recess box
according to Figure 1. Ensure all required clearances are

met.

Ensure recess box anges are ush with the nished wall

surface. For new construction, the sides of the recess box
are marked with guidelines to allow for ½” (1.3cm) and 5/8“
(1.6cm) drywall thickness if drywall is to be added at a later
date. Secure recess box to studs with screws using holes pro-

vided on sides or ange of recess box. Remove appropriate

electrical knockout and secure supply wire using an approved
strain relief connector leaving 6” (15.2cm) of wire leads in the
recess box.

Step 3 - Mounting the Heater Assembly

Insert the heater assembly into the recess box ensuring that
the tab on the heater assembly slides into the slot in the re­cess box. Ensure the heater assembly is fully seated and se­cure to the recess box using the captive screw provided.

Be careful not to handle the heater where the cutout is located.

Step 4 –Electrical Connections

WARNING: Hazard of severe shock.
CAUTION: Disconnect all power coming to heater at main

service panel before wiring or servicing.

Turn off power supply at the electrical panel. Route supply
wires from circuit breaker through wall thermostat to heater.
For models with built in thermostat route from circuit breaker
to heater.

Supply wire must be of two wire plus ground variety, with a
rating capable of handling all loads on the circuit. Supply wire
should be rated for a minimum of 140°F (60°C). Make electri­cal connection according to relevant wiring diagrams. Make
connections using approved wire nut connectors and secure
the grounding wire to the ground screw on the heater chassis.

Step 5 – Secure the Front Panel

If your unit has a built in thermostat remove the plug on the
front panel. Fasten the Front Grille using the screws provided.
It is important to note that the front grille is oriented in the
required positions shown in Figure 1 and on the Multi – Direc­tional grille. For units with built in thermostat push knob onto
thermostat shaft through plug hole.

Operation and Maintenance

WARNING: This heater must be properly installed before it

is used.

 WARNING: Disconnect power and heater has cooled be-
fore 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.

For units with built in thermostats, rotate the thermostat knob
fully clockwise. Heater should activate. When the room reach­es the desired temperature, slowly rotate the knob counter­clockwise until unit shuts off. The heater will automatically
cycle around this preset temperature setting.

All units contain a Manual Reset High Temperature Cutout,
which will shut the heater off in the event of abnormally high
operating temperatures. The high temperature cutout can be
reset by switching the main power off and waiting ve min­utes before switching it to back on. In addition a Red Warn­ing Light will activate providing a visual warning. If this condi­tion exists, disconnect all power to the unit and call a licensed
electrician for service. Do not use heater until the problem is
determined and corrected. ENSURE POWER TO THE UNIT

IS DISCONNECTED PRIOR TO SERVICING OR PERFORM­ING CLEANING.
