GENERAL

FAILURE TO UNDERSTAND AND FOLLOW THESE

INSTRUCTIONS AND THE “WARNING” NOTES THEREIN

MAY RESULT IN SERIOUS PERSONAL INJURY FROM

ELECTRICAL SHOCK, OR FROM THE HEATER FALLING

DUE TO FAULTY INSTALLATION.

1. This heater is not intended for use in hazardous atmospheres

where flammable vapors, gases, liquids or other combustible

atmospheres are present as defined in the National Electrical

Code. Failure to comply can result in explosion or fire.

2. ELECTRIC SHOCK HAZARD. Disconnect all power before

installing or servicing heater. Failure to do so could result in per-

sonal injury or property damage. Heater must be installed by a

qualified person in accordance with the National Electrical Code,

NFPA 70.

3. ELECTRIC SHOCK HAZARD. Any installation involving elec-

tric heaters must be performed by a qualified person and must be

effectively grounded in accordance with the National Electrical

Code to eliminate shock hazard.

4. Do not mount mercury type thermostat directly on unit.

Vibration could cause heater to malfunction.

5. The heater must be mounted at least 7’ above the floor to avoid

accidental contact with the heating elements or fan blade

which could cause injury.

6. Keep at least 5’ clearance in front of the heater. Refer to

Figure 1 for side, top and back clearance requirements.

7. The ceiling mounting structure and the anchoring provisions

must be of sufficient strength to support the combined weight

of the heater and mounting bracket.

8. The wall or mounting surface, and the anchoring provisions

must be capable of supporting the combined weight of the

heater and the mounting brackets cantilevered from the

mounting surface.

9. Fan blade rotation must be checked. If airflow is not moving

out through the louvers, interchange any two of the three cus-

tomer power leads on three-phase units only.

Heater Location Instructions:

Arrange units so their discharge air streams:

A. Are subjected to minimum 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 discharge 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 A.

Large rooms require multi-unit installations. Number and capaci-

ty of units will be determined by volume of building and square feet

of floor area to be heated. Arrange units to provide perimeter air cir-

culation where each unit supports the air stream from another.

FIXED MOUNTING (OPTIONAL)

NOTICE — These heaters are designed for wall and ceiling mount.

Other modes of mounting voids factory warranty.

Mounting Heaters with the Standard “L” Brackets (Optional -

Model FMB1)

Vertical Airflow

1. Height above floor

It is recommended that heater only be used with ceiling heights

of 12 feet or greater. Minimum spacing to ceiling is 12 inches,

use 1/2” thread stock (supplied by others) as shown in Figure 2.

B. Mimimum mounting height is 10 feet from floor to bottom of

heater (Figure 2)

2. Spacing to walls

A. Side of case to walls 18”. (See Figure 2.)

Horizontal Airflow (Non-Swiveling)

1. Height above floor

In areas where ceiling height is more than 12 feet, recommended

mounting height is approximately 10 feet to underside of heater.

B. For ceiling heights of 12 feet or less, maximum mounting

height is determined by use of the mounting bracket offered for

these heaters. Minimum spacing to ceiling is 9”. (See Figure 1.)

C. In either case the minimum mounting height is 7 feet from

floor to bottom of heater. (Figure 1)

2. Spacing to adjacent walls (See Figure 1).

A. Rear of case to back wall 1-1/2” minimum.

B. Side of case to side wall 8” minimum.
