1 ROUGH OPENING PREPARATION (continued)
E.Apply sill flashing tape #1. Cut a piece of flashing tape 12" longer than the opening width. Apply at the bottom of the opening as shown (1E) so it overhangs 1" to the exterior.
Note: The tape is cut 12" longer than the width so that it will extend 6" up each side of the opening.
F.Tab the sill flashing tape and fold. Cut 1" wide tabs at each corner (1/2" from each side of corner) (1F). Fold tape to the exterior and press firmly to adhere it to the water resistive barrier.
G.Apply sill flashing tape #2. Cut a piece of flashing tape
12" longer than the opening width. Apply at the bottom, overlapping tape #1 by at least 1". Do not allow the tape to extend past the interior face of the framing (1G).
Note: The flashing tape may not fully cover the framing members.
2 SETTING AND FASTENING THE WINDOW
A.Install and level sill spacers. Place 1" wide by 3/8" thick spacers on the bottom of the window opening 1/2" from each side.
Spacers are also required at points where windows are joined in multiple window applications. 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 remove plastic shipping spacers located between the window sash and frame. The shipping spacers will help keep the window square during installation. DO NOT unlock or open the window until it is fully fastened.
Note: If screens, grilles or hardware are removed from the window at this time, label them and store them in a protected area.
C.Fold out installation fin to 90°. Be careful not to remove or tear the fin corners.
Note: If the fin is not at 90°, the window will not line up correctly on the interior.
