WARNING

Read Carefully - These instructions are written to help you prevent

difficulties that might arise during installation of heaters. Studying the
instructions first may save you considerable time and money later.
Observe the following procedures and cut your installation time to a
minimum.

1. To prevent possible electrical shock, disconnect ALL power com­ing to heater at main service panel before wiring or servicing.

2. All wiring must be in accordance with the National and Local
Electrical Codes and the heater must be grounded as a precau­tion against possible electrical shock.

3. Verify the power supply voltage coming to the heater matches the
ratings printed on the heater nameplate before energizing.

4. This heater is NOT suitable for use in hazardous locations as
described by the National Fire Protection Association (NFPA).
DO NOT use in areas where gasoline, paint or other flammable
liquids are used or stored. DO NOT use in wet areas or areas
where corrosive agents are present, such as marine, green
house, chemical storage, swimming pool, or areas of high
humidity, unless special custom panels are used. Special custom
panels may be available for certain environments. Contact manu­facturer for details.

5. To prevent a possible injury or fire from falling panels, panels
MUST be securely fastened to the building structure.

When T-bar Mounted: The T-bar grid work frame must be
secured to the building to provide adequate support for the pan­els. Holes are provided in the sides of each panel for attachment
of steel support wires for additional support of the panels where
the T-bar grid work frame strength is questionable. Support wire
must be steel and at least 18 gage (0.047 in. dia. / 0.119 cm. dia).
When Surface or Recess Mounted: The surface or recess mount­ing frame accessory kits (Models ASF . . . or ARF . . . ) must be
used. Kits must be sized to match heaters being used. Do not
drill holes, drive nails, screws, etc., into or through panels. To do
so may result in fire, electric shock, or permanent damage to
heater. Surface or recess kits must be securely fastened to build­ing structure using a minimum of four (4) 1/4 inch (.635 cm) diam­eter screws or bolts.

6. To prevent possible fire due to the overheating of wiring, all field
wiring coming to heating panels must be rated at least 90° C
when junction box is allowed to lie on top of heating panel or is
enclosed between heater and ceiling above. When thermal insu­lation is used on top of heater, the junction box must be above
the insulation.

7. Panels are intended for ceiling installation only. Do not install on
walls, floor, etc. Painted (bottom) surface of panel is hot. Panels
must be installed at least seven (7) feet off floor and should not
be installed where panels can be easily contacted during use.
Keep combustibles at least 3 feet (0.9m) from face of heater.

GENERAL

Marley Engineered Products Radiant Heating Panels are
designed to provide comfort by warming the surfaces
below the heaters just as the sun warms surfaces through
radiant energy. This heating process heats objects in a

Although the heater contains thermal insulation, it will
operate more efficiently in well insulated rooms. Four or
more inches of insulation above an exposed ceiling will

increase both comfort and economy.
room without having to bring the room air temperature up
to the same level. These panels are ideal for spot heating
in high heat loss areas. Panels may be installed side by
side or individually above areas requiring additional heat. If
used as a sole source of heat, more heat will be felt while

The heaters are intended to be controlled by a remote wall

mounted thermostat. The thermostat should be located in

the same room on a side wall. It should also be above

five feet above the floor, but not directly under the heater.

operation the owner may notice a “new smell” coming
from the heaters. This is expected on new installations

nd will dissipate after approximately 24 hours of opera-

a
tion.

PAINTING

1. Heaters may be repainted. Do not remove paint from
heaters. The surface must be first free of grease or
oil. Use only a thin brush-on coat of high quality pure
acrylic water base flat latex. An off-white will give better
coverage.

Do not paint with aluminum, oil base, vinyl-latex or
rubber-base latex paint.

T-BAR MOUNTING

1. The heater panels are designed for installation in T-Bar
ceilings.

CAUTION

To prevent possible injury from falling panels, the T-Bar
must be securely fastened to the building structure and
capable of supporting the weight of the panel (30
pounds). Extra holes are provided for suspending the
heater panel (see Fig. 1) on steel wires no smaller than
No. 18 ga. (0.047 in. diameter / 0.119 cm diameter).
These extra support wires must be used where T-Bar
strength is inadequate or where vibration is anticipated.

2. Three (3) inch (7.67cm) minimum distance must be pro­vided between the front painted surface and the ceiling
above. However, installation may be difficult and six (6)
inches (15.2 cm) or more clearance will improve instal­lation of heaters and inspection or wiring. It may be nec­essary to remove a cross tee for installation when T-Bars
are at close distances to the ceiling.

3. Locate T-Bar hanger wires at the corners where the
cross tees intersect the main tees so that they do not
interfere with installation or removal of panels.

4. The heater panels are supplied with four built in hang­ing/hold-down clips which are located on each long side of
the heater panel. The clips can be used either to hang the
heater with support wires (see Figure 1) or bent as hold
down clips to the T-Bar frame (see Figure 2). Carefully lift
heater panel into place, making sure hold down clips hook
securely over T-bar (see Figure 2).

CAUTION

To prevent possible injury from electric shock, make
sure that electricity is turned off at the main switch. All
wiring must be done in accordance with national and
local codes and the unit must be properly grounded as
a precaution against electrical shock.

WIRING

1. Maximum number of heaters per circuit is limited to cir­cuit wiring and thermostat or switch capacity. See cata­log for available thermostats and Warning No. 2.

2. Make wiring connections in accordance with Fig. 3 (on
following page) and wiring instructions. The heater must
be properly grounded as a precaution against electrical
shock. Use a properly grounded junction box for con­necting the heater to the power supply.

3. Always use a properly grounded junction box when
splicing. See wiring diagrams for proper connections.
Install only in a location where the power supply con-

nections will be accessible. Install junction box as far
above panel as possible and above building insulation,
where present. Use field wiring suitable for 90 ºC if
junction box is allowed to lie on heater or is enclosed
between heater and ceiling above. When installed in a
drop ceiling, the wiring terminals should be accessible
through removable ceiling sections with adequate clear­ance to permit access to the top of the heater.

contain two side frames, two end frames, and eight assem­bly screws.

2. Assemble the end frames to the side frames using the
screws provided (see Fig. 4) before installing on the ceiling.

CAUTION

To prevent possible injury from falling panels, use at
least four screws (1/4" or 0.635 minimum diameter) to
secure each side frame. Screws must thread securely
into a sturdy structural member of the ceiling, such as a

eiling joist. It may be necessary to frame-in an extra

c
support member. Do not finish from dry-wall, plater or
other finish ceiling materials.

make wiring connections (see Fig. 3 and WIRING instruc­tions). The heater must be properly grounded as a precau­tion against electrical shock. Use a properly grounded junc­tion box for connecting the heater to the power supply.

CAUTION

Be sure electricity is turned off at main switch before
wiring to prevent possible injury from electric shock.

frames as shown in Fig. 5.

CAUTION

Be sure electricity is turned off at main switch before
wiring to prevent possible injury from electric shock.

5. Connect the heater panel leads to the power supply leads
(see Fig. 3 and WIRING instructions). The heater must be
properly grounded as a precaution against electrical shock.
Use a properly grounded junction box for connecting the
heater to the power supply. The heater may be moved along
side frames to facilitate wiring.

6. Re-assemble the end frame to the side frames to lock the
heater panel securely in place.
