Step 3: Measure and frame out the outside wall plenum opening

Measure your outside wall as shown in the
illustration. Cut, frame, and square rough
opening. The Wall plenum has a 3/4" break
all the way around to cover the rough cut
opening or required shim.

IMPORTANT: THE WALL PLENUM IS NOT
DESIGNED TO CARRY STRUCTURAL
LOADS. A PROPER HEADER OPENING
MUST BE BUILT INTO THE ROUGH
OPENING. THE PLENUM REQUIRES
FLASHING, SHIM AND CAULK FOR A
WEATHER-RESISTANT INSTALLATION.

IT IS THE RESPONSIBILITY OF THE
CONTRACTOR TO PROPERLY INSTALL
THE PLENUM AND MEET BUILDING
CODE REQUIREMENTS.

Step 4: Install Architectural Louver on the Outside Plenum

The VPAL2 Architectural Louver is best installed onto the Outside Plenum (Part A) prior

NOTE:

to Wall Plenum installation. Louver installation is easier at this point, and it will help keep
the Wall Plenum square during installation.
