TPI Corporation 3900WW28 User manual

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
limitingdevice.
RECOMMENDATIONS FOR DRAPE
PLACEMENT NEAR BASEBOARD HEATER
1. Allowminimumclearanceof1”fromdrapestoceiling
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
incontactwithheater. Somefabricsdiscolorin 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 200oF.
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
theheater.
5. Do not install vinyl curtains, drapes or blinds above
the heater as they may discolor or deform.

REV: 081403 - PN 8920

THE FOLLOWING STEPS SHOULD BE TAKEN FOR INSTALLATION
Verify input voltage and name plate voltage of heater for compatibility. Wiring can be done from either end of
heater. Ainside or outside corner section is available for right angle mounting of two baseboard heaters and
allowance should be made for locating wiring. See Figure 2 for knockout locations.
MOUNTING AND WIRING
1. Position the heater in the required location
preferably on an outside wall under a window.
2. Determinewhichendthe powersupply willenter
theheater. (This heatercanbewiredfromeither
end). Drill the appropriate hole into the wall or
floorfor the power supply, see Figure 2 for
knockoutlocations. Makesurethattheelectrical
power supply is disconnected at the circuit
breakerpanel.
3. Remove the wiring compartment cover. If the
power supply is entering on the back of the
heater remove the knockout, install the cable
connector (not provided) and feed the wire
through the connector. Leave about 6 inches
of wire extending into the box for connection. If
the power supply enters on the bottom of the
heater, remove plug button from the bottom of
the wiring compartment, install the cable
connector (not provided) and feed the wire
throughtheconnector. Pushanyexcess cable
into the wall or floor.
4. Remove the front cover of the baseboard. The
front cover is snapped on the element retainer
brackets. Position the heater on the wall and
determine the stud locations. Drill 3/16 inch
holesintherearenclosure using the drill guide,
seeFigure2. Securethe heater to the wallwith
minimum #8 screws 1 inch long. Snug the
heater up against he wall then back the screws
off about 1/2 inch to allow for expasion. If a
studisnotavailableusetheappropriatefastener
such as toggle bolts or molly screw anchors
for hollow walls or screws and anchors for
masonry walls.
5. Replace the front cover by snapping it over the
element retaining brackets.
6. Remove the wire nut in the wiring compartment
and connect the power supply as shown in the
wiring diagrams, Figure 3. If you are using one
of the field installed accessories, refer to the
wiring diagram provided with the accessory.
7. Replace the wiring compartment cover and
restorepowerto the circuit. Turnthethermostat
up and wait 2-3 minutes to see if the heater is
operatingproperly.If the heaterisnotoperating
disconnect the power at the circuit breaker box
and check wiring.
CLEANING INSTRUCTIONS
At the beginning of each heating season, it is
recommendedthat heatersbecleaned toeliminate
any accumulation of dust or lint. Before cleaning,
makesurethe powers isOFFatthe circuit breaker

attachment of the vacuum cleaner and move from
end to end and above and below fins and cabinet.
When cleaning is complete, turn power ON.
IN CASE OF PRODUCT FAILURE: It is the
obligation of the owner to furnish to the company
withinthe designatedwarranty period,thefollowing
information:
1. Model number and date of manufacture of
product involved and date of purchase.
2. Complete description of the problem
