2PREPARE THE OPENING (CONTINUED)
C.Remove plastic wrap and card board 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 window until it is fully fastened in the opening.
Note: If screens, grilles or hardware are removed from the window at this time, label them and store them in a protected area.
D. Test fit the window.The window should be approximately 1/2” smaller than the opening in both width and height. Measure the distance between the frame and the sloped sill, this will be the height to which to cut the sill adapter. Check to ensure the window rests against the exterior blind stops and will make contact with the sealant to be applied in steps 3 A, B, and C. Confirm the installation screws will fasten into solid wood. If not, repair the existing frame to ensure there is solid wood at the installation screw locations.

E.Trim the sill adapter to the proper height by breaking off the grooved leg at the desired dimension (see chart). Once trimmed, apply a bead of sealant to the sill adapter. Attach the sill adapter into the sill by using a board and hammer.
Note: Scoring the leg groove multiple times at the desired dimension with a utility knife will help the leg break easier. The sill adapter may also be trimmed to correct dimension using a table saw.
