IMPORTANT
CAUTION: In order to prevent equipment damage
the wall or ceiling mounting structure and the
anchoring components must be of sufficient
strength to support the combined weight of the
heater and mounting brackets. (Refer to Table A in
Service Reference 5200-2474-000 for weight of
heater.)
Adequate stiffness should be provided to ensure that unwanted
vibrations or movements of the complete system do not occur.
Such vibrations or movement could be induced by electric motor
start-up, or be transmitted to the heater from the structure to which
it is mounted, as in mobile installations. Where heaters are
installed in applications that are of a relocatable or transportable
nature (such as drilling rigs) design the mounting structure to with-
stand all probable load conditions. Such load conditions should
recognize accidental situations such as truck off-loading impacts.
For complete installation, operation and maintenance instruc-
tions refer to Service Reference Bulletin 5200-2474-000.
INSTALLATION
CAUTION: In order to prevent nuisance tripping of
the overtemperature cutout or heater damage
mount only in upright position and observe name-
plate mounting clearances.
Heater Location Instructions:
Arrange units so their discharge air streams:
A. are subjected to a minimum of interference from columns,
machinery and partitions.
B. wipe exposed walls without blowing directly at them.
C. are directed away from room occupants in comfort heating.
D. are directed along the windward side when installed in a
building exposed to a prevailing wind.
Locate thermostat on interior partition walls or posts away
from cold drafts, internal heat sources and away from heater dis-
charge air streams.
Small rooms can be heated by one unit heater. Where two walls
are exposed, the heater should be mounted as shown in Figure 1.
Large rooms require multi-unit installations. Number and capacity
of units will be determined by volume of building and square feet
of floor area to be heated. Arrange units to provide perimeter air
circulation where each unit supports the air stream from another.
The X Series hazardous location heaters are designed for use
only in a permanently mounted upright position. We recommend
the use of a mounting kit (ceiling, wall or pole) available from
Marley.
The ceiling or wall mounting surface and the anchoring provi-
sion must be sufficient to support the combined weights of the unit
and mounting hardware.
If using mounting hardware or a supporting structure not sup-
plied by Marley, the unit should be suspended from the supporting
structure thru the two mounting points on top of the unit with 5 /
8
NC bolts and lockwashers. If single point mounting is desired,
order the correct size adapter bracket (P/N 027-302361-001 for
12” fan units, P/N 027-302361-002 for 16” fan units, and P/N 027-
302361-003 for 20” fan units Figure 2). This bracket is designed
to hold the unit over its center of gravity with a 1” Dia. bolt. The
maximum tilt angles, as shown in Figure 3, must not be exceeded
in either direction during operation and installation. Failure to
comply will cause high limit shut down.
