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 locate these heaters below any electrical conven­ience receptacles.

8. Do not install these heaters against combustible, low

density cellulose bre surfaces.

9. 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.

10. To prevent a possible re, do not block air intake or ex-
haust in any manner.

11. 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.

12. 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: Wiring procedures and connections should

be in accordance with the National Electric Code (NEC &
CEC) and local codes.

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.

Recommendations for Locating Drapes and Furniture
near Heaters

For most satisfactory operation of the baseboard heaters and
minimum effect on drapes and furniture, the following recom­mendations should be observed:

1. Hang drapes so that, in use, they extend below the center
line of the heater, but with at least 1.5 inches clearance from

the nished oor covering (such as carpet, if used).

2. Hang drapes so that there is at least 3 inches between the
extreme front of the heater and the nearest fold of the drapes
in the folded back (opened drape) position.

3. Hang drapes so there is at least 1.5 inches between the top
of the drapes and the ceiling.

4. To be suitable for draperies located close to heaters, material
should not discolour nor distort dimensionally (stretch or
shrink) upon extended exposure (1000 hrs.) to a temperature
of 200º F (93º C).

!

NOTE: If drapes are to be cut off above a heater, they

should be cut off at least 6 inches above the top of the
heater and preferably more.

!

NOTE: Place furniture no closer then 3 inches from the

baseboard heater.

Wall Installation

1. Unpack the heater from the carton and remove the front
panel and terminal box covers.

!

NOTE: The front panel screws are recessed in the

bottom louvers at each end of the heater.

2. Determine the correct mounting height and scribe or snap
a level line on the wall to maintain each heater back plate
in a horizontal alignment, when mounting.

!

NOTE: Bottom air inlet heaters are to be mounted a

minimum of 3” from the bottom of the heater to the n­ished oor.

3. Remove the desired knockouts from the terminal box area.
(See Figure 1)

!

NOTE: It is only necessary to remove the knockout(s)

that will feed the power supply wiring, keeping in mind the
heater mounting location and supply wire location on the
wall.

4. Mount the back plate to the wall using suitable fasteners

(provided by the customer) using the
scribed line on the wall to keep the
heater level.

!

NOTE: Should the wall surface be

uneven, secure the heater back panel to
the high spots. This will avoid a distorted
appearance.

5. Proceed to the wiring instructions.
