Installing Plenum Connector
NOTE: The plenum connector is designed for
use on ducts down to 12" wide. On typical ducts,
the plenum connector may be installed using
Method A. On narrow ducts, there may be
insufficient clearance to bend the tabs on two
sides of the plenum connector. In such cases,
use Method B or C.
Method A
1. Place plenum connector through floor opening
with bottom tabs resting on top of supply air
duct. Mark cutout area around inside of tabs.
2. Remove plenum connector and cut out duct
opening slightly larger than area marked.
