Pella 80YV0102, Replacement Instructions Manual

Note:  On the exterior, there must be enough room for backer rod and 3/8" sealant 

bead.

N. 

Insert shims between the window

 and the 

opening at the top two anchor hole locations 

in the window jambs. Keep shims back 1/2" 

from interior face of window.

M. 

Insert the window and center it in the opening to allow 

clearance for shimming.

Note:  Use of a suction cup on the glass will assist in 

handling the window.

Note:  Each existing window frame and wall depth will vary 

in different applications; therefore there is not a standard 

measurement for the overhang of the window frame to 

the exterior or for the distance from the interior face of the 

window to interior trim. When performing Steps 4B thru 4D, 

installing the frame screws, be sure to keep the distance 

consistent all around the window.

NOTE 

4M

Note:  Position shims to ensure they allow at least 1/2" from the exterior surface of the 

window to allow for placement of backer rod and sealant.

O. 

If additional installation holes are needed;

 drill a 5/32” installation hole through 

both the interior and exterior walls of the frame. Counter drill a 3/8” hole through the 

interior wall only of the frame. DO NOT penetrate the exterior wall with the 3/8” bit.

P. 

Fasten the window near the top of the opening

 by 

driving 2-1/2" long wood screws through the top two 

holes at the jambs and into the opening sides.

Q. 

Plumb and square the window.

 Insert shims between 

the window frame and the rough opening at the 

anchor hole locations in the window frame. Keep 

shims back 1/2" from interior face of window.

Note:  DO NOT shim above the window or in the 

space between the spacers at the bottom of the 

window. DO NOT over shim.
