Before You Begin

Installer and Builder Information

S Read these instructions thoroughly BEFORE beginning to

install your Marvin window product.

S Always provide a copy of these instructions for the current

or future building owner.

S 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.

S Refer to the Technical Installation Sp ecifications 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 pressure (DP) rating of this product.

Aftermarket Products

Alterations to Marvin products including window films, insulating or reflective interior window treatments or additional glazings
can cause excessive heat buildup and/or condensation. They may lead to premature failures not covered under warranty by
Marvin Windows and Doors.

Before purchasing or applying any product that may affect the installation or performance of Marvin windows contact the
manufacturer of aftermarket product/glazings that are not supplied by Marvin and request written product use, associated
warranties and damage coverage. Provide this information and warranties to the end user and/or building owner for future
reference.

S It is the responsibility of the builder, installer and

subcontractors to protect the interior and exterior of
windows or doors from excessive contact with harsh
chemical washes, construction material contamination and
moisture. Damage to glazing, hardware, weatherstrip 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.

S Refer to the enclosed painting and staining instructions on

the last page for exterior and interior finish instructions.

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
using material less than 2

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.

2. For standard wood frame construction, prepare the
opening following local codes, ASTM E2112--1, or fol­low 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.

(c)

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.

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 cus­tomer service number etched on one of the top
corners of the glass. See figure 3.

2. Remove any shipping clips unless noted other­wise.

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 factoryapplied
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 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.

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 c ontinuous air barrier
system, prepare the opening before installing the window. Refer to the “Continuous Air Barrier Systems” section
for details.

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.

1. If rigid sill pan is not used, pan sill with alternatemeth­ods or shim under window sill to ensure it does not
come in direct contact with treated lumber.

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 sec­tion for details.

3. Center the window in the opening. Level at the sill
and plumb the frame (interior/exterior) to desired
depth.

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.

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.

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.

propriate fastener (follow instructions in 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 “Spe­cial 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 operat­ing properly. If not, you may have to make some addi­tional adjustments to the shims and fasteners.

9. If removed, replace your stops, covers, and liners.

Continuous Air Barrier Systems -- Preparing the Opening

The following section shows the recommended rough opening preparation for both air barrier and building paper
scenarios where a flanged, rigid sill pan is used. Refer to the “Rough Opening Preparation--Alternative Method”
section if you do not use a rigid sill pan. Refer to ASTM E2112--1 for the other situations not covered in this document.

1. Trim air barrier across top of head jamb. Trim up
from the bottom corners about 2″

(51) (or half the

height ofthe panning flange) and then make an addi­tional horizontal cut about 2 1/2″

(64) wide (or the

width of the panning flange). Fromthe horizontal cut,
make two 45 degree cuts toward the center.Cut ver­tically from the head jamb to where the two 45s
meet. See figure 15a.

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.

3. Run a bead of sealant approximately 3/4″
the edge of the opening. Start the bead about 6″
up from the sill (or the height of the sill panning). See
figure 15b.

4. Install rigid sill panning following manufacturer’s in­structions. 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.

5. Apply a continuous bead of sealant 3/4″
and sides of window opening (or where casing or cas­ing flange will contact the structure). Do not apply
sealant to RO bottom. See figure 15d.

(330) piece of Grade D building paper

(610) longer than the RO height (adjust width for

jamb depth).Tack the pieces inplace, overlapping the
RO by as much as the jamb depth. Use a utility knife
to cut the paper even at the head jamb and sill. Fold
jamb flaps to the interior and tack in place. See figure
16d.

5. Apply a continuous bead of sealant 3/4″
top and sides of window opening. Do not apply seal­ant to RO bottom. Seal any fasteners used to attach

1. Apply nailing fin corner gaskets to each corner of the
nailing fin. Follow instructions on back of gasket.

(Units with clad flat casing do not use corner gas­kets.)

2. If not completed, install a drip cap along the head
jamb or head jamb casing. Be sure to apply a bead
of sealant along the back sides of both vertical and
horizontal surfaces of the cap that come in contact
with the window, window casing, and/or sheathing.
See figure 17a.

3. Lap vertical strips of self sealing adhesive mem­brane onto the unit or casing and out over the air bar­rier. Make small cuts at the head jamb to allow the
membrane to fold back onto the exterior. See
figure 17b.

4. Install another layer of adhesive membrane lapping
onto head jamb of unit and over sheathing. Mem­brane flashing at head jamb should extend and cov­er flashing membrane previously installed at jambs.
See figure 17b.

5. Fold head jamb air barrier down over the head jamb
flashing. Apply seam seal tape over the diagonal cut
in air barrier. Make sure the tape laps onto the unit
or casing. Tape and seal any seams and fasteners
directly above the unit. See figure 17c. Proceed to
the “Final Sealing Procedures” section.

NOTE: Figure 19 shows a window with casing but the flashing detail applies to any clad window product.

For installations in typical wood frame construction or brick veneer (non recessed masonry openings), figure 19
shows the proper flashing detail in shingle style fashion. Once the exterior finish such as siding or brick veneer is
installed, a bead of sealant should be applied between the finish and the window/window casing along the sides and
approximately 1--2″

(25--51) in from the ends at the head jamb. Use a backer rod when necessary.

Removing Interior Stops, Liners and Fillers

Some structural installationsthat 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

(b)(a)

Figure 20: Removing Casemaster stops and covers.

1. Sill and head jamb covers and stops are held in place
with avinyl barb and canbe easily removed bysimply
and carefully prying up on the stop with a sharp putty
knife. Be careful not to damage the stop or frame. Oc­casionally the barb will stay in the frame when youre­move the stop. Remove the barb with a pair of pliers
and reinsert into the kerf on the stop/cover. See fig­ure 20a.

NOTE: Stationary jamb stops are removed in the same
fashion. You will need to remove the head jamb and sill
covers first.

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. Start at one end
and work your way down until stop loosens. See fig­ure 20b.

Figure 21

1. Remove the head jamb parting stop with use of a pry
bar. See figure 21a.

2. Use a flatheaded tool with a 90 degree elbow to re­move the lower fillers from the jamb hardware assem­bly . 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 try­ing 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.

3. From the exterior, pry out the jamb hardware assem­bly 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.

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.
