! WARNINGa
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 |
Although the heater contains thermal insulation, it will |
designed to provide comfort by warming the surfaces |
operate more efficiently in well insulated rooms. Four or |
below the heaters just as the sun warms surfaces through |
more inches of insulation above an exposed ceiling will |
radiant energy. This heating process heats objects in a |
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 |
The heaters are intended to be controlled by a remote wall |
in high heat loss areas. Panels may be installed side by |
mounted thermostat. The thermostat should be located in |
side or individually above areas requiring additional heat. If |
the same room on a side wall. It should also be above |
used as a sole source of heat, more heat will be felt while |
five feet above the floor, but not directly under the heater. |
standing directly under the panel. |
|
SAVE THESE INSTRUCTIONS
NOTE: For a period of time after the panels are put into |
|||||||
operation the owner may notice a “new smell” coming |
|||||||
from the heaters. This is expected on new installations |
|||||||
and will dissipate after approximately 24 hours of opera- |
|||||||
tion. |

|
|
|
|
|
|
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 pro- |
|||||||
|
vided 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 instal- |
||||||
|
lation of heaters and inspection or wiring. It may be nec- |
||||||
|
essary 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 hang- |
|||||||
|
ing/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.

|
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 |
|
|
||||
ceiling joist. It may be necessary to frame-in an extra |
|
|
||||
support member. Do not finish from dry-wall, plater or |
|
|

||||||||
the date of installation. |

The customer shall be responsible for all costs incurred in the removal or reinstallation of products, including labor costs, and shipping costs incurred to return |
||||||||
products to Marley Engineered Products Service Center. Within the limitations of this warranty, inoperative units should be returned to the nearest Marley |

authorized service center or the Marley Engineered Products Center, and we will repair or replace, at our option, at no charge to you with return freight paid |
||||||||
by Marley. It is agreed that such repair or replacement is the exclusive remedy available from Marley Engineered Products. |
