Pella 81CP0101 installation instructions Setting and Fastening The Window, Pella SmartFlash Tape

3 Setting and Fastening The Window

A. Test fit the window in the opening from

the exterior. Insert shims around the

window temporarily while you verify that

the window will fit into the opening and

the window flanges will overlap the stucco

or existing aluminum window frame by a

minimum of 3/4" on all (4) sides.

Note: Fix any problems with the opening

before proceeding. If required, the

exterior flush flange may be trimmed to

fit inside exterior surround trim. Lay the

window down on a flat surface. Use an

electric shears, circular saw or table saw to

cut the flange.

DInsert the window from the exterior of the building and center the window in the prepared opening.

E.Place a shim aligned with the top pre-drilled hole in one jamb of the window frame. Trim all shims so they are recessed back 1/4" - 1/2" from the interior face of the window frame. Partially insert one 3-1/4" finish wood screw. Repeat on the other jamb.

F.Continue placing shims at each pre-drilled hole as needed to plumb and square the window. Check the window for square by making sure the diagonal measurement from corner to corner of the replacement window is within 1/8" in both directions. Insert a 3-1/4" finish wood screw into each pre-drilled hole in the frame. Finish inserting the top screw in each jamb.

Note: DO NOT shim above the window. DO NOT over shim.
