WARNING
Read Carefully - These instructions are written to help you pre-
vent 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.
To reduce risk of fire or electric shock:
1. Disconnect ALL power coming to heater at main service panel
before wiring or servicing. Make sure power is off when
installing heater assembly into backbox.
2. All wiring must be in accordance with National and Local
Electrical Codes and the heater back box must be grounded.
3. Verify the power supply voltage coming to the heater matches
the rating printed on the heater nameplate before energizing.
4. This heater is NOT suitable for use in hazardous locations as
described by the NFPA. This heater has hot and arcing or
sparking parts inside. DO NOT use in areas where gasoline,
paint or other flammable liquids are used or stored.
5. This heater is hot when in use. Keep electrical cords, drapery,
foam filled articles, bedding, and other furnishings away from
heater. DO NOT install this heater in a manner where the hot
discharge air is blowing directly on any items that may be
damaged by heat such as plastics or clear vinyls. The heat
from the heater could cause discoloration to these materials if
their temperature rating is less than 150˚F (65˚C).
6. This heater is intended for installation into the floor ONLY. DO
SAVE THESE INSTRUCTIONS
NOT install in wall, ceiling or in any manner where air flow
through heater may be obstructed. DO NOT install heater
without enclosure. DO NOT install side of heater closer than
6” (152mm) to wall or end of heater closer than 36” (914mm)
to wall.
7. DO NOT operate the heater without the grille installed. Grille
must be secured with the two screws provided to prevent
unintentional removal.
8. This heater is NOT intended for use in wet locations where
heater could become soaked with water.
9. DO NOT insert or allow foreign objects to enter any heater
openings as this may cause an electric shock, fire, or permanent damage to heater
10. Since this heater is intended for floor installation, it is more
likely to become dirty and require routine maintenance. It is
recommended that the heater be cleaned and serviced at
least annually. Failure to keep heater clean could result in a
fire or premature heater failure.
11. This heater is provided with an alarm (buzzer or warning light)
that will sound (or illuminate) if the heater is overheating. This
is intended to alert the user of the hazard and initiate action by
the user to correct the abnormal condition that exists. DO
NOT continue to use the heater if the alarm is sounding (or
light is on). The repeated cycling of the alarm indicates the
heater is in need of cleaning and/or servicing.

GENERAL INSTRUCTIONS
!
!
When installing the heater(s) as draft barriers below windows it is
ecommended that the heater(s) capacity be matched to the heat
r
loss of the glass area. Also, the heat spread of each heater is
about 5 feet (1524mm) so for continuous draft control heaters
should be mounted 5 feet (1524mm) apart.
hen using the heater(s) as the sole source of heat in the room,
W
the capacity of the heater(s) should match the heat loss of the
room. For good room temperature control, a Marley wall thermostat mounted on an inside wall is recommended.
o prevent discoloration of some synthetic drapery materials and
T
to avoid undue wall discoloration, the side of the heater should be
at least 1inch (25,4mm) from the drapes nearest fold and the end
of the heater should be no closer than 3 feet (914mm) to the wall
(See specifications and Warning No. 6).
