2 | INNER |
SILL |
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 14
from the bottom of the sash to the window stool.
2.If storm window presents interference, fasten a 2
wide wood strip(not included) (OUTER SILL) 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 (STORM WINDOW FRAME) or wood strip (OUTDOORS) to help condensation to drain properly to the outside.
3.Install a second wood strip (approximately 6
long by 3/2
wide and same thickness as first strip) in the center of the outer sill flush against the back off the inner sill. This will raise basepan angle .
4.If the distance between STORM WINDOW FRAME and WOOD STRIP MOUNTED ON TOP OF INNER SILL is more than 1
, two of wood strip are not necessary.
