face of the existing blind stops at the head and both jambs.

C. Place a bead of sealant where the jamb and sill meet.
D. Insert the window into the opening. Set the bottom of the

window in first and tilt the top into place. Make sure the

window is centered in the opening and is pressed firmly

against the exterior blind stops.

E. Place a shim at each of the top corners in line with the pre-

punched holes, and partially insert 2-1/2" screws (provided).

This will hold the window in place while shimming it plumb

and square. Trim shims back so they recessed back 1/4” -

1/2” from the interior face of the window frame.
