Replacement Hopper Window Installation Instructions

The following must be done to insure warranty coverage. All vinyl replacement windows are designed to be installed plumb, square and level. If the installer does not meet these simple requirements, the appearance, operation and weatherability of the unit will be affected.

After verifying that the window will fit into the existing opening, remove hopper from plastic wrapping.

Cut a 3" wide strip of fiberglass insulation and lay it on your sill prior to setting the new window into the opening. This will help prevent drafts from entering under the window.

Lifting the unit with two hands set it into the opening, hold the hopper into place while installing screws, do not fully tighten screws yet.

Verify unit is plumb, level and square (See Figure 1) . If needed use wood shims to ensure window is level and square. Do not over shim.

Check window for easy operation. Complete installation by attaching window frame to opening with screws.

Fill in any cracks between sides of unit and opening with fiberglass insulation (or non-expanding, low pressure foam insulation).

Note: Shimming your hopper window is important as it helps center the unit, prevents bowing out the side frames and to keep the window operating smoothly, and as air-tight as it was built.
