Step Two − Unit Preparation - Marvin Window User Manual

Step 2
: Unit Preparation
1. Remove the protective packaging from the unit
and dispose/recycle properly. Inspect unit for
any hidden damage and report immediately to
your Marvin representative. Provide the cus-
tomer service number etched on one of the top
corners of the glass. See figure 3.
2. Remove any shipping clips unless noted other-
wise.
NOTE: Do not remove the vinyl shipping blocks
or shipping tube assembly on Ultimate Double
Hungs until installation is complete (unless
installing with jamb screws).
3. If used on clad units, position the factory applied
nailing fin/drip cap in the upright position. See
figure 4.
4. On wood units with brick mould casing, apply
sealant at the casing to frame joint along the
jambs and head jamb, at the sill horn to casing
joint, and at the miter corners of the casing. See
figure 5. Tool the bead to ensure proper adhe-
sion to both surfaces.
5. If you are installing a window with structural
brackets, fasten to the window now. Follow the
fastener spacing in the "Jamb/Sill Screw
Chart". Follow the instructions provided with
the brackets for details on how to fasten to unit.
Ultimate Double Hung Magnum units are sent
with supplemental instructions which detail how
to remove the sash and jamb fillers.
6. If you will be fastening with screws through the
jambs, head jambs, and sill, remove your sash
and covers or liners at this time. Refer to the
section, "Removing Interior Stops, Liners,
and Fillers" and "Removing Sash" for details.
7. Install jamb extension before installing the win-
dow in the rough or masonry opening. Follow in-
structions provided with the jamb extension.
