LOCATION OF HEATER

Heaters should be located to provide a blanket of
heat over the coldest wall of the room, preferably
on a outside wall under a window.

CAUTIONS AND WARNING STATEMENTS

1. Wiring procedures and connections should be

in accordance with national and local codes
having jurisdiction.  Note: all baseboards must
be grounded in accordance with article 250 of
the National Electrical Code.

2. Do not install baseboard heater below electrical

convenience receptacles (outlets).

3. Do not install heaters against combustible low

density cellulose fiberboard surfaces.

4. High temperatures are present at outlet air

openings.  Keep electrical cords, drapes and
other furnishings or objects clear of these
openings.

5. To reduce risk of fire, do not store or use

gasoline or other flammable vapors and liguids
in the vicinity of the heater.

6. Heaters are designed for surface mounting only.

Do not recess the heaters into the wall.

7. Do not tamper with or remove the temperature

limiting device.

RECOMMENDATIONS FOR DRAPE
PLACEMENT NEAR 
BASEBOARD HEATER

1. Allow minimum clearance of 1” from drapes to ceiling

and to top of floor covering to permit air circulation
(Example 1, Figure 1).

2. Hang full length drapes to provide a minimum of 2”

air space between heater front and nearest drape
fold as shown in Example 1, Figure 1.

3. Hang short drapes to provide minimum of 6”

clearance between bottom of drapes and top of
heater, preferably more (Example 2, Figure 1).

4. Do not under any condition allow drapery to come

in contact with heater.  Some fabrics discolor in time
from exposure sunlight or warm air. Check to make
sure drapery material will not discolor, shrink, or
stretch upon extended (1000 hour) exposure to
temperatures of 200

o

F.

Heaters may be mounted directly to any floor
surface, including carpeting.  Wall to wall carpet
(maximum thickness 3/4”) may extend under or to
the front of the baseboard heater.  This is provided
the flooring material does not obstruct air flow to
the heater.

5. Do not install vinyl curtains, drapes or blinds above

the heater as they may discolor or deform.
