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

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.
