Installation Instructions for Typical Wood Frame Construction.
These instructions were developed and tested for use with typical wood frame wall construction
in a wall system designed to manage water. These instructions are not to be used with any other
construction method. Installation instructions for use with other construction methods, multiple
units or bow and bay windows, may be obtained from Pella Corporation, a local Pella retailer, or by
visiting http://www.pella.com. Building designs, construction methods, building materials, and site
conditions unique to your project may require an installation method different from these instructions
and additional care. Determining the appropriate installation method is the responsibility of you, your
architect, or construction professional.

places to ensure the header or studs are not bowed.

C. Fold down top flap of water resistive barrier (4C).
D. Apply flashing tape to diagonal cuts. Cut pieces of flashing
tape at least 1" longer than the diagonal cuts in the water
resistive barrier. Apply the tape covering the entire diagonal
cut in the water resistive barrier at both upper corners of the
window.
Note: Be sure to overlap the top corners (4D).
Note: The flashing tape must be applied approximately 1/2" onto
the frame cladding at the jambs and head. Pre-folding the tape at
1/2" before removing the paper backing will make it easier to apply
the tape correctly. If the siding is less than 1/2" thick, adjust the
dimension of the fold so the exterior sealant
line will cover the exterior edge of the tape.
