MOUNTING

WARNING: Hazard of Electric Shock. Disconnect all power before installing heater.

Note: These heaters are designed for wall or ceiling mounting only. Other modes of mounting voids factory warranty.

1.Height above floor

A.In areas where ceiling height is more than 12 feet, recom- mended mounting height is approximately 10 feet to under- side of heater.

B.For ceiling heights of 12 feet or less, maximum mounting height is determined by use of ceiling mounting brackets offered for these heaters. Minimum spacing to ceiling is 3” (see Figure 2).

C.In either case, minimum mounting height is 7 feet from floor to bottom of heater (see Figures 1 and 2).

2.Spacing to adjacent walls

A.Rear of case to back wall 4-7/8” minimum (see Figure 2).

B.Side of case to side wall 6” minimum (see Figure 2).

3.If two or more units are operated in the same enclosed space, their discharges should be directed to aid in development of mass air movement for uniform heat dispersal.

4.Controlling thermostats to individual heaters should be mounted at shoulder height on inside walls or columns.
