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.
5.If you are installing a window with installation brackets or structural masonry clips, fasten to the window now. Follow the fastener spacing in the “Installation Methods and Fastener Spacing Chart”. Follow the instructions pro- vided with the brackets for details on how to fas- ten 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.
