2 SETTING AND FASTENING THE WINDOW
A.Install and level sill spacers. Place 1" wide by 1/4" thick spacers on the bottom of the window opening 1/4" from each side.
Spacers are also required at transition bars in multiple sash units. Add shims as necessary to ensure the spacers are level. Once level, attach spacers and shims to prevent movement.
Note: Improper placement of shims or spacers may result in bowing the bottom of the window.
B.Remove plastic wrap and cardboard packaging from window. DO NOT open the window until it is fully fastened.
2A |
Note: For best results, install the window with the sash closed and locked with the shipping spacers in place.
TWO OR MORE PEOPLE WILL BE REQUIRED FOR THE FOLLOWING STEPS.
Note: If fins are to be installed to no fin units, go to the Applying Installation Fin instructions on the back before proceeding to step C.

C.Insert the window from the exterior of the
building. Place the bottom of the window on the spacers at the bottom of the opening, then tilt the top into position. Center the window between the sides of the opening to allow clearance for shimming and insert one roofing nail in the first hole from the corner on each end of the top nailing fin. These are used to hold the window in place while shimming it plumb and square.
D.Plumb and square window. Place shims 1" from the bottom and top of the window between the window and 
the sides of the opening. Adjust the shims as required
to plumb and square the window in the opening. If the frame height exceeds 53", place shims at the quarter points of the window sides.
