WINDOW REPLACEMENT INSTRUCTIONS FOR
CASEMENT, DOUBLE-HUNG AND CLAD FRAME WINDOWS
USING FRAME SCREWS
These instructions were tested and developed for replacing windows in wood-frame wall construction systems designed
to manage moisture. 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.
Note: This instruction is not for use in applications that have vinyl, steel or aluminum siding where water may be behind the
siding above the window. In these applications, the siding may need to be removed and window installed using the new
construction installation instruction that is attached to the window.

the space from the back of the backer rod to the interior face of the opening.
B. Check window operation (vent units only) by opening and closing the window.
Note: If the window does not operate correctly, check to make sure it is still plumb, level, square and that the sides are not
bowed. If adjustments are required, remove the foam with a serrated knife. Adjust the shims, and reapply the insulating
foam sealant.
Interior Finishing:
6
Visible wood surfaces of Pella® products must be finished. Failure to do so voids the Limited Warranty. If products cannot
be finished immediately, cover with clear plastic film to protect from dirt, damage and moisture. Remove any construction
residue before finishing. Sand all wood surfaces lightly with 180 grit or finer sandpaper. DO NOT use steel wool. BE

Note: To maintain proper product performance do not paint, finish or remove the weather-stripping, mohair dust pads,
gaskets or vinyl parts. Air and water leakage will result if these parts are removed. If paint, stain or finish gets on the mohair
weather-stripping, immediately blot it thoroughly with a rag and allow it to dry. Flake off any remaining residue. After
finishing, allow windows to dry completely before closing them.
Pella Corporation is not responsible for finishing imperfections. Use of inappropriate finishes, solvents, brickwash or
cleaning chemicals will cause adverse reactions with window and door materials and voids the Limited Warranty.

CARE AND MAINTENANCE

IMPORTANT NOTICE
Because all construction must anticipate some water infiltration, it is important that the wall system be designed and
constructed to properly manage moisture. Pella Corporation is not responsible for claims or damages caused by
anticipated and unanticipated water infiltration; deficiencies in building design, construction and maintenance; failure to
install Pella® products in accordance with Pella installation instructions; or the use of Pella products in wall systems which
do not allow for proper management of moisture within the wall systems. The determination of the suitability of all building
components, including the use of Pella products, as well as the design and installation of flashing and sealing systems are
the responsibility of the Buyer or User, the architect, contractor, installer, or other construction professional and are not the
responsibility of Pella.
Pella products should not be used in barrier wall systems which do not allow for proper management of moisture within the
