Step 1: Rough Opening and Framing Requirements
This section gives requirements for framing and rough opening clearances. Masonry or concrete openings must be
lined with a treated wood product (wood buck). You must fasten the buck to the masonry opening in a fashion that
will withstand conditions which would be encountered under the certified and advertised DP ratings for this window.
The structural integrity of this installation is only as good as the bond between the wood buck and the masonry
opening. For more details, contact your Marvin representative.
NOTE: Wood buck material thickness may vary. Illustrations show a 1/2″ plywood and 2 x 4 buck. Installations

Figure 1: Preparing openings for concrete block openings.
1. On concrete block, masonry, or similar situations, line
the sides, head jamb, and sill with treated lumber.
Attach the lumber to the masonry opening with
construction adhesive and masonry anchors which
should penetrate the masonry opening by at least
1″-- 1 1 / 2 ″ (25--38). See figure1a and 1b.
NOTE: If your installation requires screwing through
the sill for structural purposes, place a bead of sealant
where the screws will penetrate the rigid sill panning.
4. The window frame must not come in contact with
treated lumber. If you will not be using rigid panning
or shimming at the sill, apply a barrier such as a self
sealing adhesive flashing to the rough opening sill.
See figure 1 c.
2. For standard wood frame construction, prepare the
opening following localcodes, ASTME2112--1, orfol-
low the steps in the “Continuous Air Barrier Sys-
tems” section.
3. If rigid panning is used, place a bead of silicone or
construction adhesive over any fasteners used to
hold the panning to the sill.

higher. Masonry openings (MO) should be 1/2″ (13)
wider than the outside measurement of the frame or
casing and 1/4″ (6) higher than the outside measure-
ment of the frame or casing. When framing rough
opening, care should be taken to ensure the sill plate
is levelandtheopeningis square, straightandplumb.
See figure 2.
ATTENTION: Be aware that use of rigid sill pans and
other barriers will decrease the rough opening height
clearance. Adjust opening dimensions accordingly.
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.
NOTE: On standard wood frame construction with
brick veneer, make sure there is at least 1/2″ (13)
between bottom of window sill (or eventual
placement of the window) and the top row of brick
to avoid “brick bind”.

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.
Customer service number
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. Ifused 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.

Step 3: Installing the Window
The following steps provide details for structural fastening of the window to the opening. When installing windows
with nailing fin or wood brick mould casing, it may be desirable to first attach the window using these fastening
methods in conjunction with steps 1--5. Then complete the installation by fastening with structural masonry clips,
installation brackets, or screws. Always follow fastener spacing and allowable methods outlined in the “Installation
Methods” and “Fastener Spacing Chart” sections. On applicable construction using a continuous air barrier
system, prepare the opening before installing the window. Refer to the “Continuous Air Barrier Systems” section
for details.

Figure 6: Plumb and square unit. (Illustration shows both masonry clip and jamb screw installation.)
5. Fasten and shim about 4″ (102) from the top 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 and fasteners until the
unit is square in the opening. See figure 6b.
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.
CAUTION: Proper shimming is extremely
important. Under--shimming or over--
shimming will result in bowed jambs and

or head jamb. Both conditions can contribute to
improper window operation and performance.
2. On some larger units such as the Ultimate Double
Hung Magnum, it may be necessary to remove the
sash prior to installation. See the sash removal sec-
tion for details.
Installation Tip: On operating units, one
method to ensure 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 indicates a correctly
installed unit and will ensure smooth operation.
3. Center the window in the opening. Level at the sill
and plumb the frame (interior/exterior) to desired
depth.
4. Fasten and shim the jambs at the bottom with the ap-
propriate fastener(follow instructionsin the “Fasten-
ing Methods” section). See figure 6a. Ultimate
Double Hung Magnum are sent with supplemental
instructions that explain how to fasten through the
jamb and head jamb.
NOTE: Some units such as the Ultimate Double Hung
Magnum and IZ3 Ultimate Double Hung, feature unique
fastening systems. For these windows refer to the “Spe-
cial Fastening Systems” section for details.
6. Complete shimming and fastening at locations and
spacing specified in the “Installation Methods and
Fastener Spacing Chart”. See figure 6c.
7. Recheck the diagonals one more time to make sure
the unit is square in the opening. Adjust fasteners as
necessary to bring to square.
8. Once the unit is installed square and plumb, operate
the sash (on operable units) to make sure it is operat-
ing properly. If not, you may have to make some addi-
tional adjustments to the shims and fasteners.
9. If removed, replace your stops, covers, and liners.

Fastening Methods (cont.)
Jamb/Sill Screws
1. After removing covers or liners, fasten units to the
framing with #8 wood screws or 3/16″ concrete an-
chors1. Adjust length of fastener so that it penetrates
no less than 1 1/4″ (32) into framing/opening. When
fastening through the sill, always pre--drill and fill
hole with sealant before driving the screw. Always
place a shim behind or above the screw location on
jambs and head jambs.
3. On Ultimate Double Hung units, locate the screw in
the jamb carrier kerf (jambs) and in the kerf used to
hold the parting stop (head jamb). Make sure to
countersink the screw so that it doesn’t interfere with
installation of the jamb liner and/or parting stop. See
figure 10.
NOTE: When using masonry anchors, be sure to follow
manufacturer’s guidelines for proper installation. Some
types require pre--drilling.
2. On Casemaster units, position the screw so that it
misses any operating hardware (if applicable). With
typical installations, you should be able to locate the
screw in the center groove in the frame and just to the
exterior of the kerf that holds the head jamb stop. See
figure 9.
Fastener
Figure 10: Exterior View, fastening through UDH frames.
4. On IZ3 Ultimate Double Hung units, fasten through
the “Storm Brackets” on the jambs with two

clad accessories to finish the exterior. If this is the
case, apply a bead of sealant between the acces-
sory and the masonry at the head jamb and jamb
sections. Leave the sill portion unsealed to allow
water to escape. See figure 13c.
2. For recessed masonry applications, Marvin recom-
mends sealing at the buck to frame joint with ap-
propriatewidthbackerrodandsealantaroundtheen-
tire perimeter. Finish as applicable local code dic-
tates. See figure 13b.

foam insulation on the back side of the nailing fin,
brick mould casing or other trim. Do not apply too
muchas itis possibletobow thejambs. Now insulate
loosely around the window with fiberglass insula-
tion. See figure 14.
5. 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 sta-
ples that are no longer than 3/4″ (19). Place fasten-
ers at least 1″ (25) from the edge of interior jamb
liner.

Figure 15: Rough opening preparation for construction methods using a continuous air barrier system and rigid sill panning.
1. Trim air barrier across top of head jamb. Trim up
from the bottom corners about 2″ (51) (or half the
heightofthe panning flange) and then make an addi-
tional horizontal cut about 2 1/2″ (64) wide (or the
width ofthe panning flange). Fromthe horizontalcut,
make two 45 degree cuts toward the center. Cut ver-
tically from the head jamb to where the two 45s
meet. See figure 15a.
3. Run a bead of sealant approximately 3/4″ (19) from
the edge of the opening. Start the bead about 6″ (152)
up from the sill (or the height of the sill panning). See
figure 15b.
4. Install rigid sill panning following manufacturer’s in-
structions. Wrap side flaps to the interior and tack in
place. Seal the horizontal cut in the air barrier with
seam seal tape. See figure 15c.
2. Flip top flap up and tack in place temporarily. Fold sill
portion to the interior and tack in place. The side
flaps should be loose until rigid panning is installed.
See figure 15b.
5. Apply a continuous bead of sealant 3/4″ (19) from top
andsides ofwindow opening(or wherecasing or cas-
ing flange will contact the structure). Do not apply
sealant to RO bottom. See figure 15d.
ATTENTION: Be aware that use of rigid sill pans and
other barriers will decrease the rough opening height
clearance. Adjust opening dimensions accordingly.

Removing Interior Stops, Liners and Fillers
Some structural installations that use the “jamb pinning” method require the removal of interior stops before installing
the window. This section details the removal of Ultimate Double Hung (UDH) jamb liners and Casemaster operator
and stationary stops. More detailed information can be found in the Marvin Service Manual.
Details for UDHM windows can be found in the supplemental instruction sent with the unit.
Removing Casemaster Stops and Covers

Figure 20: Removing Casemaster stops and covers.
1. Sill and head jamb covers and stops are held in place
withavinylbarbandcanbeeasilyremovedbysimply
and carefully prying up on the stop with a sharp putty
knife. Be carefulnotto damage the stop or frame. Oc-
casionally the barb will stay in the frame when you re-
move the stop. Remove the barb with a pair of pliers
and reinsert into the kerf on the stop/cover. See fig-
ure 20a.
2. Operator jamb covers are held in place by two barbs:
one on the interior side and one on the exterior side
shared by the frame weather strip. With the sash
opened or removed, first pull the frame weather strip
out of the kerf and set aside for reuse later.
3. Remove the sill and head jamb stops.
4. With a sharp putty knife, carefully pry on the interior
side between the stop and the frame. Startatone end
and work your way down until stop loosens. See fig-
ure 20b.
NOTE: Stationary jamb stops are removed in the same
fashion. You will need to remove the head jamb and sill
covers first.

3. From the exterior, pry out the jamb hardware assem-
bly using a pry bar by placing it into the bottom filler
channel, hooking it into the notches on the side, and
levering it out. See figure 21c.
2. Use a flatheaded tool with a 90 degree elbow to re-
move the lower fillers from the jamb hardware assem-
bly. This is best done by placing the tool into the space
opened by the removed checkrail pad. Loosen both
corners of the jamb fillers from the notches before try-
ing to remove them, to reduce the possibility of damage
to the fillers. See figure 21b. Be sure to take care when
doing so, as there is a possibility of the fillers breaking.
4. When installation of the unit is complete, seat the
jamb assembly facing towards the exterior first, and
ease the remainder of the assembly into the jamb
pocket. See figures 21d and 21e. Use of a rubber
mallet may be required. If so, take the mallet and,
starting at one end, work your way up the filler, until
fully seated. (Use of a cloth to protect the wood and
keep it clear from direct impact while hammering is
suggested.)
5. Reinstall the checkrail pads and head jamb part stop.
