Window Requirements
NOTE: All supporting parts should be secured to firm wood, masonry, or metal.
1. This unit is designed for installation in standard double hung windows with actual opening widths of
22" to 36". The upper and lower sash must open sufficiently to allow a clear vertical opening of 13"
from the bottom of the sash to the window stool.
2.If a storm window presents interference, fasten a 2" wide wood strip to the inner window sill across
the full width of the sill. The wood strip should be thick enough to raise the height of the window sill
so that the unit can be installed without interference by the storm window frame.
See Fig. 5-2. The top of the wood strip should be approximately
frame (STORM WINDOW FRAME) or wood strip (OUTDOORS) to help condensation to drain
properly to the outside.
3. Install a second wood strip (approximately 18" long by 1
in the center of the outer sill flush against the back off the inner sill. This will raise the L bracket as
shown in Fig. 5-2.
4. The thickness of the second wood strip may not be the same as the first wood strip.
The thickness of the second wood strip must be defined to keep the
inner sill or the top of the first wood strip and the outer sill.
