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
