Installing the Back Supply Plenum
Installing the Supply Duct Collar
1. Find the center of the Back Supply Plenum.
. If the Back Supply Plenum is less than 9 ft. 10 in. (99.7 cm) long,
cut opening at the suggested location, centering the opening over
the center of the Back Supply Plenum. (Fig. 9)
3. If the Back Supply Plenum is greater than 9 ft. 10 in. (99.7 cm)
long, divide the length of the back supply by four. This will give you
the center of each half. Cut openings at the suggested location,
centering the duct collar over the center measurement of each
half. (Fig. 10)
4. Place the duct collar(s) over the opening, fastening with screws or
tack-welds every 4 to 6 in. (10.16 to 15.4 cm). (Fig. 11)
