These instructions were tested and developed for replacing windows in wood-frame wall
construction systems designed to manage moisture.
This method of installation involves
removing the sash only of the existing window. The original window frame will remain
in place and only the existing sash, exterior stops and frame hardware must be removed.
Installation recommendations for other types of wall construction, wall systems or conditions may
be obtained from Pella Corporation or a local Pella retailer. 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 on your part. Determining the appropriate
installation method is the responsibility of you, your architect, or other construction professional.
REMEMBER TO USE APPROPRIATE
PERSONAL PROTECTIVE EQUIPMENT
CAUTION:
Many windows in older

paint. Removal of old windows may
