Keep at least 5’ clearance in front of the heater. Refer to Figures 1 and 2 for side, top, and back clearance requirements. The wall or ceiling mounting structure and the anchoring provision must be of sufficient strength to support the combined weight of the heater and mounting bracket. (Refer to Table A for weights of heater and bracket). Fan blade rotation must be checked. If airflow is not moving out through the louvers, interchange any two of the three customer power leads on three-phase units only. MOUNTING WARNING: Hazard of Electric Shock. Disconnect all power before installing heater. WARNING: 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, 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 ceiling mounting brackets offered with these heaters. Minimum spacing to ceiling is 14-1/4”. C. In either case the 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 11” minimum. B. Side of case to side wall 12” minimum. 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. WIRIN...
