Plenum Installation
NOTES:
• A properly sized header and rough in framing must conform to all national and local building codes.
• Before caulking and permanent attachment, dry fit the outside plenum into the rough opening and check for fit,
squareness and that the plenum is level.
• When securing the plenum into the opening drive screws into the vertical sides of the plenum only. Water may
penatrate into framing if screws are driven into the bottom of the plenum. See Detail A below.
1. Install Outside Wall Plenum
Prior to the outside plenum being inserted into the rough opening for the final time, flashing should be installed and
the plenum should be caulked along the flange on all four sides to provide a weather-resistant seal. With the plenum
properly caulked, push the outside plenum into the rough opening until the flanges of the plenum are against the
wall. Once installed, the outside plenum should be securely attached to the frame opening. Drive screws through the
vertical sides only to secure the plenum (Detail A).
Caulk may need to be applied to the outside of the building along the plenum frame to insure a water tight seal.
