Installation Instructions for
Double Hung Replacement Windows |
Double-Hung/Standard Wood-Square, Level, Plumb |
Insulate the window sill opening prior
to setting the masterframe in place. With a level on the masterframe sill,
adjust the masterframe unit so the sill is level. Shim as required. Install
a screw in the lower corners of the masterframe jambs. There are pre-drilled
holes located behind the sash stops. Now level the masterframe jambs and
insert the installa-flon screws in the upper corners of the jambs. Snug
the installation screw. Do not over tighten |
|
Insulate the jambs and
header of the window. Make sure that the masterirame jamb sections and
sashes make full contact with each other. Shim the masterframe as needed
to ensure that all sash finseal weatherstrippings make full contact with
the master-frame.
Operate and tilt both sashes
prior to replacing the trim to be sure that both function properly and
that all adjustments are complete. Reinstall the existing or new interior
trim and caulk the interior and exterior perimeters of the window unit.

Coil Stock & Sill Angle
If the sill is to be covered with coil stock, apply coil
stock prior to setting window unit into opening. Extend coil stock approximately
1" under window unit and nail so that nails will be covered with the
window once it is in place. Always pitch coil stock so that water will
run oil, and not sit against the window unit. |

|
For installation into an
opening with a sloping sill, a sill angle is provided to accommodate the
angle of slope. Apply the sill angle in the groove behind the screen track
(DIH units), which is behind the exterior leg of the unit's masterframe.
Always have window overlap sill angle and coil stock to reduce risk of
water infiltration. |
