All Riviera V4 windows have a 7/8” flange and are designed to be fastened through this flange
into a post/structure. (Self-drilling screws are supplied).
Step 1:
Remove sashes from main frame by compressing springs to the left and
lift out the right side from the shallow depth frame liner. (See Photo A)

Step 2:
Check for correct fit of window into opening. Gap should be 1/8” on each
side and 1/8” at top and bottom.
Step 3:
Center and square-up window frame in opening. Fasten a screw into each
top corner. (See Fig. 1)
Step 4:
Fasten a screw into each bottom corner.
Step 5:
Use shims to maintain the same window width in the middle of the
vertical
sides as the top and bottom. An hour-glass shape will make the window
operate poorly.
Step 6:
Fasten the sides with screws at each meeting rail. (See Fig. 2)
Step 7:
Fasten the header & sill with a screw in the middle.
Step 8:
Insert sashes. (See Photo B) Top sash is closest to screen.
