STEP 3
Install Grille Kit RAVAL4 (not included) on the Outside Plenum
NOTE: The Grille Kit RAVAL4 is best installed
onto the Outside Plenum (Part A) prior to the wall
plenum being installed into the building. Grille
installation is easier at this point and will help keep
the wall plenum square during installation.
If you are not installing the grille at this time be
sure the plenum is square when installed in the
opening and do not remove the weather cover.
NOTE: Refer to instructions included in the
Grille Kit RAVAL4 for proper installation
procedure.
STEP 4
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 plenum into the rough opening to check for fit,
squareness and level.
Caulk the wall plenum
on the rough opening
side of the wall plenum
flange.
