5. Loosen screw in built-in cable clamp (Figure 4) 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 cover-
ing second hole up and back to rear wall of wiring compart-
ment. If built-in cable clamp is not used, install approved
cable restraint (not included ) in desired knockout.
N
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 screw in center is required.
Tighten screws and then loosen screws at least ¼ turn to
allow heater to expand and contract during use. If unit is
mounted above floor, two additional mounting holes are pro-
vided 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 ¼ turn.
7. Connect the supply cable grounding wire to the bare copper
pigtail in wiring compartment.
8. Follow the desired wiring diagram, as shown in Figure 5, to
connect the power supply to the heater using approved wire
nuts.
NOTE: When accessories are installed, use wiring diagram
supplied with the accessory.
9. If front cover was removed, reinstall by hooking the top edge
on the support bracket(s). Then push down to latch onto the
support bracket(s).
10.Replace wiring compartment cover(s).
11.Follow instructions accompanying thermostat for installation
and wiring thermostat. Visit www.marleymep.com for typical
thermostat wiring diagrams.
OPERATING INSTRUCTIONS
1. This heater must be properly installed before it is used.
2. After the baseboard system has been completely installed,
all thermostats should be turned 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 control is provided to turn off the heater auto-
matically 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 page 2. During normal use, this safety control
should not operate. If you find that this control is operating,
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.
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 com-
partment covers and the front cover. Using a vacuum cleaner
or compressed air, remove the dust and lint from the alu-
minum heating element fins while being careful not to dam-
age 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 it is latched 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
If it becomes necessary to repaint heater, use only a quality
enamel paint suitable for metal surfaces following the instruc-
tions provided with the paint. DO NOT paint the heating element
or safety limit capillary tube. Repaint only the exterior of the
cabinet.
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 burn.
2. Use care when cleaning element fins to avoiding damaging
fins. Note also that fins are sharp and may cause cuts so
avoid contact.
