Accessory VPAWP Manual (2020)

NOTE The VPAL2 Architectural

Louver is best installed onto the

Outside Plenum (Part A) prior to

Wall Plenum installation. Louver

installation is easier at this point,

and it will help keep the Wall Ple-

num square during installation.

Step 4: Install Architectural Louver on the Outside Plenum

After the rough cut opening is prepared, you are ready to assemble the two wall plenum parts. Before ap-

plying sealant and permanent attachment, dry t the outside plenum into the rough opening and check for

t and level. Caulk (silicone recommended ) the parts well and insert them into the wall as shown.

A) Apply sealant and insert Outside Part A into the hole.

B) Apply sealant and insert Inside Part B into Part A. Be sure that Part A does not back out of the wal-

hole.

Step 5: Plenum Installation

Note Proper header and wall penetration must conform to all national and local building codes.

Apply sealant to all

8 ange corners and
