NOTE: For most efficient operation locate heaters along outside
wall under windows. Position heater

so

it can be secured to

wall stud. Power cable must enter heater through built

in

cable

clamp or one of the knockouts provided in wiring compartment.

2. Drill hole

in

wall (or floor) at desired location for power supply
entry. Install power supply wiring to heater and thermostat
location as determined

by

thermostat option selected. Allow
approximately 10 to 12 in (254mm to 305mm) of wire at
heater for connections.

3.

installation instructions provided with the accessory for prop­er installation and wiring. Visit www.marleymep.com for
instructions

on

some common accessories.

4. Wireway Cover - Commercial Baseboard Only
a.

The wireway cover is a factory installed feature of Marley
commercial baseboard heaters. Two cables or four indi­vidual conductors plus two ground wires may be routed
through the wireway. Refer to page

1,

Table 1 for wire

size and current loads.

b.Togain access to wireway, lay heater face down and

remove the screws holding the wireway from the back of
the heater. Remove the knockouts in the channel areas of
both terminal boxes.

TO REDUCE

THE

RISK OF FIRE AND ELECTRIC SHOCK

OR INJURY

TO

PERSONS, OBSERVE THE FOLLOWING:

1.

Serious injury or death could result from electric shock.
Make sure electrical power supply circuit coming to heater
is

disconnected at main disconnect or service panel before

installing this heater.

2.

Wiring procedures and connections must beinaccordance
with

the National Electrical Code (NEC) and local codes.

Refer to Wiring Diagrams Figure

5.

Make sure all electrical
connections are tight to prevent possible overheating. Use
Copper Supply Wire Only.

3. Verify the electrical power supply voltage matches the volt-

age

rating as printedonthe heater nameplate - see Figure

1.

CAUTION - Never connect a heatertoa voltage greater than

the nameplate

voltage as this will damage the heater and

could

causeafire"

4.

Do

not install the heater against combustible low-density

cellulose

fiberboard surfaces, against or below

Vinyl

wall
coverings, or below any materials that may be damaged by
heat such as

Vinyl

or plastic blinds, curtains, etc.

5.

Do

not install heater belowanelectrical convenience recep-

tacle (outlet).

6. CAUTION - Heater Operates at High Temperatures. Keep
Electrical Cords (including telephone and computer cables),
Drapes, and Other Furnishings Away From Heater. For effi­cient and safe operation, we recommend maintaining a min-

imum of 6 inches (152 mm) clearance above and

in

front of
the heater at all times. See Figure 2 for minimum clearance
requirements for drapery.

7.

To reduce the risk of fire,donot store or use gasoline or
other flammable vapors or liquids in the vicinity of the
heater.

8.

Do

not install heater upside down orinany position other

than

as

showninthis manual. Caution label with word

"TOP" must

be

at the top when heater is installed.

9.

Do

not recess heaterinwall or install heater inside any type
enclosure as this will cause heater to overheat and could
create a hazard.

10. When mounting heater, if bottom mounting holes are used
(see Figure 4), make sure screws

do

not damage supply

wiring

in

the area behind heater.

11.

Do

not remove or bypass the safety limit controlasthis

could allow heater to become a fire hazard - see Figure

4.

When

using RSA Transformer Relay Accessory, supply

wiring provided

in

compartment where this accessory is

installed, must

be

1ror, if desired, above floor (such

as

above the baseboard).

, to 3/4 inch (19 mm)ofcarpeting may be installed up to and

around heater as long

as

it does not obstruct the air flow.

Heater to Drapery: do not install heater where curtains or drap­ery will contact the heater.

See

Fig. 2 for required minimum

clearances.

5.

Loosen screwinbuilt-in cable clamp (Figure4)or remove
desired knockout from heater wiring compartment. Install
power cable into wiring compartment allowing at least

6

in

(153mm) of cable for connection to heater. To install two

power cables using the built-in cable clamp, bend tab cover­ing second hole

up

and back to rear wall of wiring compart­ment. If built-in cable clamp is not used. install approved
cable restraint (not included) in desired knockout.

NOTE:

cross stamped mounting perforations are provided

in
back of heater enclosure above heating element at mounting
screw locations, see Figure

4.

6.

Position heater at desired location and attach to wall using
wood screws or appropriate hardware. Locate studs and
drive screws into studs where possible. For heaters up to 6

feet (1.8

m)

in length, one screw at each end is adequate.

For longer units,

an

additional screwincenter is required.

Tighten screws and then loosen screws at least

14

tum to

allow heater to expand and contract during use. If unit

is
mounted above floor, two additional mounting holes are pro­vided at each end below the heating element (see Figure 4).
Install an additional screw at each end for stability making
sure to loosen each screw at least

14

turn.

7. Connect the supply cable

grounding wire to the bare copper

pigtail in wiring compartment.

and wiring thermostat. Visit www.marleymep.com for typical

thermostat wiring diagrams.

OPERATING

INSTRUCTIONS

1. This heater must be properly installed before itisused.

2.

After the baseboard system has been completely installed,
all thermostats should be tumed to LOW or NO HEAT.
Turn on breakers, wait 3 to 5 minutes and check to see that
none of the heaters are operating.

If

operating, disconnect
power and check wiring. If none are operating then turn
thermostats to highest position and wait 3 to 5

minutes.

Check to see that all heater(s) are operating. Should any not

be operating, disconnect power and check wiring.

3. Allow entire system to operate steadily for 1/2 hour. This
should remove oily residue from manufacturing. (Some
smoking may occur).

4. Select the setting for comfort on all thermostats.

5.

A safety limit controlisprovided to tum off the heater auto­matically if it

is

blocked or otherwise overheats due to

an

abnormal condition-see Figures 4 and

5.

DO

NOT

bypass or
remove this safety device from the electrical circuit-see
Warning

11

on page2.During normal use, this safety control
should not operate. If you find that this controlisoperating,
make sure the heater

is

not being blocked. If it continues to

cycle the heater

off,

disconnect power to heater and have it

checked and repaired by a qualified electrician.

MAINTENANCE

INSTRUCTIONS

Your heater will give you years of service and comfort with only
minimum care. To assure efficient operation follow the simple
instructions below.

A

WARNING

A

1.

Serious injury or death could result from electric shock.
Make sure electrical power supply circuit coming to heater
is disconnected at main disconnect or service panel before
servicing this heater. Allow heater to cool before cleaning

to prevent a possible bum.

2. Use care when cleaning element fins to avoiding damaging
fins. Note also that fins are sharp and may cause cuts so
avoid contact.

1. The user

can perform some basic cleaning of the heater. All

other servicing is to

be

done by qualified service personnel.

2. Because of the convection heating principle which depends
upon a circulation

of

air through the finned element, dust will

collect between the fins. The heater should

be

cleaned regu-

larly for maximum efficiency.

3.

To clean heating element fins, first remove both wiring com­partment covers and the front cover. Using a vacuum cleaner
or compressed air, remove the dust and lint from the alu­minum heating element fins while being careful not to dam­age the fins.

4. The painted heater cabinet may be cleaned using a slightly
damp cloth. Do not use abrasive cleaners or waxes

as

these

may damage the finish or leave a residue that will discolor.

5.

Replace front cover (making sure itislatched in place at
each element support bracket and at each end) and two
wiring compartment covers (using the two screws

prOVided),

restore power and check heater

for

proper operation.

Painting

Ifitbecomes necessarytorepaint heater, use only a quality
enamel paint suitable for metal surfaces following the instruc­tions provided with the paint. DO NOT paint the heating element
or safety limit capillary tube. Repaint

only the exterior of the

cabinet.
