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, frame stops and frame hardware from the existing window. The original window frame
will remain in place. I
f the existing window frame shows signs of water infiltration or is damaged
beyond repair, this method should not be followed and the entire existing window should
be removed. Installation recommendations for other types of wall construction, wall systems,
conditions, multiple windows or bow/bay windows, 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.
CAUTION: Many windows in older homes are painted with lead-based paint. Removal of old
windows may disturb this paint. Proper precautions must be taken to minimize exposure to dust
and debris. Consult state or local authorities for more information.
