Horizontal Air Flow
1. Height above floor
A. In areas where ceiling height is more that 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 detemined by the use of the mounting bracket
offered for these heaters. Minimum spacing to ceiling is 7-
3/4”. (See Figure 5)
C. In either case, the mimimum mounting height is 7 feet from
floor to bottom of heater.
2. Spacing to adjacent walls.
A. Rear of case to back wall 2 minimum.
B. Side of case to side wall 6” minimum.
CEILING – Horizontal Airflow (See Figure 5):
The ceiling mounting bracket is fastened to the top of the heater
using the four (4) bolts supplied with the mounting bracket. The
bracket is then mounted to the ceiling using a 5/8" bolt (by others).
WALL – Horizontal Airflow (See Figure 6):
Wall mounting necessitates the use of both an adaptor mounting
bracket and a wall mounting bracket. First, attach the ceiling
mounting bracket to the heater. Then, attach the wall mounting
bracket to the wall using four 5/16" bolts (by others). Attach the
ceiling mounting bracket on the heater to the wall mounting brack-
et using the 5/8" bolt provided.
