Always provide a copy of these instructions for the current or future building owner. Plan sizing of rough opening and clearance from exterior finishing systems to allow for normal materials shrinkage or shifting (e.g. wood structure with brick veneer; allow adequate clearance at sill). Failure to do so can void the Marvin warranty coverage. Refer to the Technical Installation Specifications section for technical specifications regarding the installation of this product. These installation requirements as well as the details in this section must be followed to achieve the advertised design press.
It is the responsibility of the builder, installer and subcontractors to protect the interior and exterior of windows or doors from contact with harsh chemical washes, construction material contamination and moisture. Damage to glazing, hardware, weather strip and cladding/wood can occur. Protect with painters tape and/or protective sheathing as required. Follow all guidelines regarding material use, preparation, personal safety and disposal. Refer to the enclosed painting and staining instructions on the last page for exterior and interior finish instructions. Contact your Marvin supplier if you have any questions regarding product and materials used in manufacturing or questions on replacement parts.ure (DP) rating of this product.

(b) (a) NOTE: When using a sill panning product you may need to adjust the opening accordingly to account for the height of the panning. (c)
Figure 1 Typical rough opening.
1. Rough openings (RO) should be 1 (25) wider than the outside measurement of the frame and 1/2 (13) higher. (When framing rough opening, care should be taken to ensure the sill plate is level and the opening is square, straight and plumb.) See figure 1a. 2. On shapes such as polygons, round tops, and octagons, make sure there is proper bracing. See figure 1b and figure 1c.
CAUTION If the previous conditions are not met, the installer must take corrective actions to alter the opening(s) before proceeding. It is also essential that the sheathing behind the wall be a solid surface to ensure that the unit can be secured firmly to the wall.

2. If you are installing a window with installation brackets or structural masonry clips, fasten to the window now (if not installed at the factory). Follow the instructions provided with the brackets. See figure 5.
IMPORTANT STOOL HEIGHT: On Ultimate Casement units, the 8 and 14 frame bevel option max stool height is 3/4" (19). For the flat frame option the max stool height is 15/16" (24). It may be necessary to shim under the unit to reduce the stool height. This will decrease the Inside Opening Height measurement for the replacement unit. This specification is required for proper operation of the crank handle. Field application of stool material will need to follow these guidelines for proper clearance and operation of the crank handle.

Seek Assistance Some large windows and/or assemblies are very heavy. Avoid injury by getting help to lift and position the window into the rough opening. NOTE: For Round Top operator supplemental installation and squaring methods, proceed to the last section of this instruction. 1. Center the window in the opening. Level at the sill and plumb the frame (interior/exterior). Shim under the jambs to bring to level if necessary. See figure 7a. 2. Once level, tack the jambs within 4 (102) from the head jamb. If fastening through the exterior casing, use 16d casing nails.See figure 7b.
4. Once square fasten the lower corners and recheck for square. See figure 7c. ATTENTION For units installed with masonry clips or installation brackets. Bend bracket around framing member and attach with the #8 x 1 5/8 screws. Angle screws approximately 15 degrees away from the window. Always shim above or below brackets. See figure 8. NOTE: Depending on construction method or wall type, you may need to modify the clip/bracket to fit the opening. Fastening holes should be no more than 1/4 from the bend in the bracket. If necessary, drill two 5/32 (3) holes in the bracket.
Shim 1/4"
CAUTION Proper shimming is extremely important. Undershimming or over-shimming will result in bowed jambs and or head jamb. Both conditions can contribute to improper window operation. 3. From the interior, shim about 4 (102) from the bottom to square the unit in the opening. Take diagonal measurements of the window. When equal, the window is square in the opening. Adjust the shims until the unit is square in the opening. See figure 7c.

5. Shim 4-6 from the bottom corners and at 15 intervals on center as well as at every lock point. Always shim at checkrails and meeting stiles. See figure 9a. 6. Measure at head jamb, center of unit, and sill to make sure all dimensions are equal. If they are not, you will have to adjust the shims accordingly. See figure 9b. NOTE: For units installed with installation screws through the framing members, be sure to shim at each fastening location to avoid bowing/distorting jambs. 7. Once the unit is square and plumb in the opening, operate the sash (on operable units) to make sure it is operating properly. If not, you may have to make some adjustments to the shims.
Tip On operating units, one way to make sure that the unit is installed square is to check the reveal (gap) between the operating sash and the frame. An even reveal around the entire sash generally means a squarely installed unit and will ensure smooth operation. 8. Complete fastening of the casing around the perimeter of the unit with 16D casing nails 4 (102) from each corner and spaced every 8-10 (203-254) on center. 9. Interior and mullion trim: Install mullion trim after interior trim or casing is applied. On Ultimate Double Hung units, be sure to use nails and staples that are no longer than 3/4 (19). Place fasteners at least 1 (25) from the edge of interior jamb liner.

Rough Opening Width: 1/4-1 (6-25) wider than window/door frame outside measurement. Rough Opening Height: 1/4-1/2 (6-13) higher than window/door frame outside measurement. Masonry Opening Width: 1/4-1/2 (6-13) wider than window/door frame outside measurement. Masonry Opening Height: 1/8-1/4 (3-6) higher than window/door frame outside measurement.
For units with flat casing install with installation brackets, structural masonry brackets, or jamb screws. Shim 4-6 (102-152) from each corner on jambs and head jambs. Install additional shims at 15 (381) on center and at all locking points. Always shim at the checkrails and meeting stiles. Do not use chemically treated products for shim material. Fasteners penetrating chemically treated lumber must be a minimum of 0.90 oz/ft2 zinc hot dipped galvanized or stainless steel type 304 or 316. The window frame must not come into direct contact with chemically treated wood products.
Rough Opening: Width 1 (25); Height 1/2 (13). Masonry Opening: Width 1/2 (13); Height 1/4 (6). The panning must drain water to the exterior of the cladding OR the exterior surface of a concealed weather resistive barrier.
WARNING Drilling, sawing, sanding or machining wood products generates wood dust, a substance known to the State of California to cause cancer. Avoid inhaling wood dust or use a dust mask or other safeguards for personal protection. California Health and Safety Code section 25249.6.
CAUTION Be aware that the use of sill pans and other barriers will decrease the rough opening height clearance. Adjust opening dimensions accordingly.
The panning system used in these instructions is one component in a structure's overall water management system. It should be used in conjunction with an appropriate drainage plane compatible with the exterior cladding. Flashing materials must comply with ASTM E211201, section 5.13 and be compatible with all materials used in installation including panning systems, air barriers and building papers, sheathing, and the window unit. Flashing material must not contain asphalt and must be compatible with flexible PVC (vinyl). Properly flash and/or seal all windows at the exterior perimeter. Sealants used for installation must be Grade NS Class 25 per ASTM C920 and compatible with the building exterior, window exterior surface, and flashing/water management materials. Optional foams used for installation must be low expansion only. Foam and foam application must comply with ASTM E2112-01, SEC 5.9.2.
