Tools Required - 9/16" Open-End Wrench
1. Locate the four hanger bracket holes in the top of the heater cabinet (two on
each side).
2. On the side of the heater where the electrical supply connects, carefully place
two lockwashers over each hanger bracket hole. From the kit, select the hanger
bar with the wider flange and the cutout hole in the center. Position the hanger
bar along the top edge of the heater on top of the washers. (Two washers are
required between the heater and the hanger bar to allow for removal of the side
panel.). Attach the hanger bar with two of the bolts, securing them to the hanger
bracket weld nut. See FIGURE 6C.
3. Attach the left side hanger bar the same way using the remaining four washers
and two bolts.
4. The heater is ready for suspension from 3/8" threaded hanger rods. Use field-
supplied hardware to attach the hanger rods as illustrated in FIGURE 6D.
