Installation Instructions
The installation of the WD65 System requires a working
knowledge and experience in the use of tools, equipment,
and methods necessary for the installation of aluminum
doors, windows, storefronts,and/or partitions. This
practice assumes a familiarity with preparing a proper
and structurally sound opening, proper anchorage,
waterproofing, caulking,and sealing and assumes
an understanding of the fundamentals of building
construction that affect the installation of large door
systems.
Highly recommended is using an independent NanaWall
Certified Installer, if available, or, at least, an installer
who has some experience in installing NanaWall systems.
IMPORTANT: READ COMPLETE INSTRUCTIONS
BEFORE BEGINNING INSTALLATION. INSTALL AS
RECOMMENDED; OTHERWISE, THE UNIT MAY
NOT FUNCTION PROPERLY AND ANY WARRANTY,
WRITTEN OR IMPLIED, WILL BE VOID.
CAUTION:
As regulations governing the use of glazed windows,
doors, storefronts,and/or partitions vary widely, it is the
responsibility of the building owner, architect,
contractor,or installer to insure that products selected
conform to all applicable codes and regulations,
including federal, state,and local. NanaWall Systems,
Inc. can assume no obligation or responsibility
whatsoever for failure of the building owner, architect,
contractor,or installer to comply with all applicable laws
and ordinances and safety and building codes.
The WD65 system is shipped with all necessary
components. However, not included are screws, bolts,
shims, etc. to anchor the unit to the rough opening.
The frame is shipped knocked down and needs to be
assembled. Panels are pre-assembled with or without
glass, ready to be attached to the installed frame. In most
cases, all hinges, weather stripping, multiple locking, and
flat handles are pre-attached to the panels and frame
components.
DESCRIPTION OF SUPPLIED PARTS
Check all parts carefully before assembly. Depending
on the model, some of these parts may already be
pre-installed on the panels. Check that the sizes of the
frame components and panels match with what was
ordered. In the small cardboard box attached to the
frame components that contains hinge pins and various
hardware, inspect the elevation drawing, indicating size,
configuration, and labeling of the unit ordered. For orders
with multiple units, do not mix and match panels and
frames, even if two units are exactly the same. Below is a
list of supplied parts
Always looking from inside.
• Left side jamb, labeled L, and right side jamb, labeled
R.
• Head jamb, labeled O, and sill, labeled U. (In some
instances the head jamb and sill may be in segments.)
• Pre-assembled panels: rollers, guides,and locking
mechanism with flat handles are installed on the
panels. The number of panels depends on the model
ordered. The sequence of labeling of panels starts
from the left with the left most panel labeled Panel 1.
If supplied unglazed, panels have to be glazed before
being installed in the opening. See Appendix A: Glass
Installation and Glazing.
• A certain amount of hinge pins and set screw to
secure the hinge pins.

NANAWALL WD65 OWNER’S MANUAL

• Lever handles, other handles or other entry hardware
as ordered. These may be pre-attached to the panels.
• Panel holder – one for each swing door not attached
to a side jamb.
HANDLING OF COMPONENTS
1. Upon receipt, inspect the shipment to ensure it is in
good condition.
2. Make sure that the small cardboard box with the
hinge pins and other hardware does not get lost.
3. Store in a clean and dry location and protect against
defacement or damage, especially to the edges of
panels.
4. Wood components should not be subject to extreme
or rapid changes in heat or humidity, such as forced
heating to dry out a building.
5. All wood surfaces including all edges (top, bottom
and sides) should be completely sealed and finished
promptly.
PREPARATION OF THE ROUGH OPENING
For necessary clearance and adjustment space, make
rough opening about 3/4"wider and 3/8"- 1"higher than
the outside frame size of the unit ordered (check to
comply with applicable codes for maximum shim space
allowed, especially in high windload areas). It is important
that the opening be the correct size. Note that the
outside frame height of the unit ordered is measured
from the bottom of the sill and not from the finished
floor. Allowance must be made in height for the portion
of the sill that is below the measured opening.
IMPORTANT: Because of the large opening sizes
and the weight and movement of the panels, any
application should take into consideration the following:
1. The structural integrity of the header is critical for
proper operation. Vertical deflection of the header
under full live and dead loads should be the lesser of
L/720th of the span and 1/4". Structural support for
lateral loads (both windload and when the panels are
stacked open) must also be provided.
2. A qualified engineer or architect should be used to
determine the proper construction details and header
to be used in your particular application.
3. THE ROUGH OPENING SHOULD BE LEVEL, PLUMB
AND SQUARE AT ALL POINTS. THERE SHOULD BE
NO UNEVENNESS OR BOWING. MAKE SURE THAT
THE HEADER IS NOT TILTED OR TWISTED. THERE
SHOULD BE NO BUMPS ON THE FLOOR. THE
SIDES SHOULD BE IN THE SAME VERTICAL PLANE
AND NOT OFFSET OF EACH OTHER. A TRANSIT
AND OTHER SIMILAR PRECISE MEASURING
EQUIPMENT SHOULD BE USED.
4. With a recessed sill, if concrete is to be poured after
the installation of the unit, the sill has to be securely
attached to the construction. If the sill is to be cast in
concrete, then an expansion gap with appropriate
material has to be created next to the sill.
5. With a low profile saddle sill, some resistance to water
infiltration may be achieved by installing drain
connections to the outside.
If any anchorage or drain connection holes are made
through these drain channels, make sure that they are
properly sealed to prevent any water leakage. The open
ends of these drain channels at each end of the sill
should also be properly sealed. Alternative anchoring
systems for the sill (without using screws through the
drain channels) are using L brackets attached to both
sides of the sill.

NANAWALL WD65 OWNER’S MANUAL

6. For better performance and protection, any exterior
folding system should be installed under an overhang
or with other similar protection.
7. For better performance it is recommended that
all dead loads such as upper levels, roof, etc. be
constructed before a unit is installed.
Properly flash and waterproof around the perimeter
of the opening, especially at the sill. Make sure you
seek proper professional advice for the appropriate
construction needed for your particular application. DO
not install unit in structures that do not allow for proper
management/drainage of moisture.
To avoid future problems, do not install your unit until the
rough opening has been correctly prepared.

WOOD FINISHING AND MAINTENANCE
RECOMMENDATIONS
NanaWall wood framed systems are shipped with a factory
applied layer of a water born translucent coat of sand
sealer or primer, which is an acrylic-copolymer-dispersion
from Sikkens (www.nam.sikkens.com). NanaWall aluminum
clad wood framed systems are shipped with a similar
additional coat. These factory applied coatings are not
a suicient and adequate protection from the elements
and at least two coats of a final finish need to be applied
in the field.
IMPORTANT: Immediately upon receipt of the unit
and prior to installation and exterior exposure to
weather elements, all wood surfaces including all
edges (top, bottom,and sides) should be
completely sealed and must be protected with a
good quality finish. Before installation, keep the
units in a dry and clean location, store and stack
them properly to avoid twisting or warping of the
panels and frame components.
To complete the wood surface treatment use compatible
finish material. If you think the product that you are
intending to use is not compatible, then completely
remove all pre-applied coats by chemical stripping
(please follow the direction of the product) or by sanding
o. Do not use power wash or excessive water. Then apply
a good quality sealer or primer and continue applying the
necessary coats as recommended by the product you
have chosen.
CAUTION:
Not all available paints and stains, nor the customer’s
specific application requirements can be evaluated. Your
local paint professional should know of suitable finish
systems that give satisfactory results in your region. It is
highly recommended that top quality finishes be selected,
and the directions of the products be followed explicitly.
In general, the surface must be prepared by cleaning o
dust and any debris. With 180-220 grit sandpaper, sand
lightly and thoroughly all surfaces to be painted. Do not
use steel wool or silicon carbide type sandpapers. Then
clean the surfaces before applying paint, etc.
For best performance, a minimum of two topcoats should
be applied.
Always make sure that you apply the coatings on a
hidden area before finishing the whole unit to make sure
you are satisfied with the results.
Ensure not to apply the coating material on to hardware,
gaskets, glass, sealant,or aluminum surfaces to maintain
proper product performance.
All damages or scratches during installation on the
surface coating should be immediately touched up.
WOOD SIMULATED DIVIDED LITES (SDL)
It is recommend that after completing the surface
treatment of the SDL and after allowing for adequate
drying time, to seal the gaps between the SDL and glass
with a durable weather resistant caulking material, which
is compatible with the surface treatment material.
MAINTENANCE OF WOOD UNITS
As a general guideline it is recommended that every
1/2 year or earlier, to inspect visually the surface
and if necessary re-finish in the same manner as
per instructions above . The timeframe may vary on
weathering, exposure conditions and altitude. Whenever
damage is visual, it should be repaired immediately.

UNIT INSTALLATION
The Installation of the folding unit is described in the
following categories:
A. FRAME ASSEMBLY AND INSTALLATION
B. PANELS AND FOLDING HARDWARE INSTALLATION
C. FINAL STEPS
A. FRAME ASSEMBLY AND INSTALLATION
It might be easier to drill the holes as descript in Step A6
before assembling the frame.
Step A1
Lay the four frame components flat on the floor and align
the ends to be joined. If the head jamb and sill regarding
their length provided in segments, then connect them
first. If a unit has angle changes in the floor plan, then
separate information will be supplied. Make sure that
the frame components are in the correct positions. The
frame should be labeled U for sill, O for head jamb, and
looking from inside, R for right side jamb and L for left
side jamb. Note: If there are no weep holes in the sill,
please check whether such holes are required and drill
them if necessary. Please be careful to avoid scratching or
damaging the components.

Step A2
Assemble all frame parts as shown in Diagram 1. Do not
apply sealant to the corner joints yet.
Step A3
Do not screw the vertical side jambs to the head track nor
the sill. It has to be possible to slide the side jamb inwards
or outwards for adjustment.
Step A4
Be sure that appropriate flashing around the perimeter
of the opening is installed. Set the assembled frame into
the rough opening at the proper position relative to the
header. Make sure the direction is correct with respect to
inward or outward opening.
See Diagram 2 for Suggested Installation Details. Please
note that these are suggestions only and that these may
not be suitable in all applications.
Step A5
Temporarily secure the frame to the rough opening with
clamps.
Step A6
Looking on a standard installation, which is limited to
areas with a basic wind speed of not more than 90 mph,
in a low rise building (max. 60 feet roof height),Exposures
B or C and a non critical status. Fasteners locations
should start about 4"from the interior edge, drill holes for
the anchorage devices to connect the frame to the
opening at a spacing of not more than every 16"along the
head jamb and the sill. On the head jamb and sill an
additional fastener should be placed at the meeting point
of panels in the closed position and anchorage points
every 4"in the stacking area on either side. The spacing
of the side jamb should be about 14"starting at the
bottom, using an extra screw at the top. For installation
that are beyond the above limitations, a structural
engineer should be consulted for specific fastening
requirements.
Use appropriate screws or other equivalent anchorage
devices depending on the adjacent substrate material and
construction. Make sure they are corrosion resistant.
Anchorage devices should penetrate or hold sufficiently to
the opening to withstand necessary structural loading.
Generally, for wood frame use #14 (1/4"diameter) wood
screws with 2-1/2"minimum embedment, for concrete with
a minimum compressive strength of 3,200 psi use 3/16"
diameter ITW Tapcons (concrete screws) with 1-1/4"min.
embedment. For masonry use 1/4" diameter ITW Tapcons
(masonry screws) with 1-1/4"embedment. Standard
installation into light gage steel substrates with a minimum
of 18 gage (0.0451"thick) should have 1/4" diameter type
410 stainless steel self drilling screws. Into structural steel
substrates thicker than 1/4"should be pre-drilled and 1/4"
diameter SAE Grade 2 bolts can be used. Another option is
to use type 410 stainless steel self drilling screws. For this
option first drill small pilot holes.
Make sure that the screw head with washer (if any) is
small enough to fit inside the slot in the middle of the head
jamb and sill; otherwise, it will interfere with the rolling of
the running carriages.
Anchor through the center of the groove but make
sure the screw or bolt head with washer bears on the
aluminum. To maintain the thermal break, use PVC or
nylon washers so that the screw heads do not bridge the
aluminum.
Make sure that the frame is level, plumb and square at all
points. There should be no unevenness or bowing.
If, for any reason, the floor is not level, shim with plastic
horseshoe shims to the highest point of the floor, provided
there is still enough clearance at the top. Place plastic,
horseshoe type shims tightly at every fixing point between
the frame profile and rough opening. Use hard plastic
horseshoe shims only.

Step A7
Anchor the sill to the sub floor in correct relation to the
finish floor. Make sure that the sill is not tilted or twisted.
Make sure that all holes drilled through the sill are
properly sealed with silicone underneath and around
the screws.
All weep holes in the sill are not to be obstructed.
Make any necessary adjustments to level, plumb, and
square before proceeding on.
Step A8
Anchor the side jambs to studs or walls in the same
manner. Make sure that the jambs are plumb and straight.
Step A9
Anchor the head jamb through the pre-drilled holes and
shims. Make sure that the head jamb is level.
IMPORTANT: Make sure no shims are forced to
ensure that frame sections are not bowed.
Check frame constantly to be certain that it is level,
plumb and square. A transit and other similar
precise measuring equipment should be used to
make these determinations.
Step A10
IMPORTANT: Make sure that all the surfaces of the
upper and lower tracks are clean and free of any
debris, especially, cuttings from drilled holes.

B. PANELS AND FOLDING HARDWARE
INSTALLATION
IMPORTANT: Look for glass stops to determine the
interior side of a panel.
Step B1
Looking at the elevation drawing, note where the
installation slot in the head jamb is located. The slot can
be accessed by the removal of the approx. 12"small piece
of wood trim on the head track. Reach into the track to
slide the rod and open the plate. See Diagram 1.
Step B2
Start with the panel furthest away from the slot. If it is to
be hinged o the side jamb, align the hinges and insert
the proper hinge pins.
Do not force any hinge pins and do not hammer them all
the way in, let the knurling stick out.
If it is part of unhinged paired panels not hinged to the
side jamb, set lower guide that is pre-attached to the
bottom of the panel, in the lower track. Insert the upper
running carriage roller that is pre-attached on top of the
panel, through the slot in the head jamb.
Step B3
Again, looking at the elevation drawing, attach the next
panel needed to create a folding pair. Set the guide in the
lower track and insert the roller through the slot in the
head track. Slide the panel and align the hinges with the
first panel. Insert the hinge pins to create a folding pair.
If necessary, place temporary blocks under the panels to
assist in keeping the panels in a steady position.
After installation of each panel, check to make sure that
the panel is vertically straight.
Step B4
If there are additional panels to be attached to the folding
pair, close the pair by turning the handle 180°.
Step B5
Attach additional panels in the same manner.
C. FINAL STEPS
Step C1
Attach handles and other hardware that have not been
pre-attached. Attach the profile cylinder (if any) to the
locking gear by inserting it into the lock hole and
attaching the set screw through the screw hole on the
gear located at the edge of the panel. Cut the set screw, if
needed, so it is not longer than 1-1/2"to 2"depending on
locking type.
Step C2
IMPORTANT: For swing panels not attached to a side
jamb, attach the panel holder to the top of the upper
rail of the adjacent panel. See Diagram 1. Follow the
specific instructions that are on the sheet in the panel
catch kit. The purpose of this is that the swing panel
should always be opened and engaged into the panel
holder before the folding panels are to be opened.
Step C3
Close and lock all panels into position.
Step C4
Check all horizontal joints:
Make sure the head jamb and sill are still level. Then
along the entire width of the opening, check the spacing
between the sill and each panel and the spacing
between the head jamb and each panel. Both spaces
should be about 5/16"along the entire length of the unit.
Check especially to see if the upper corner of a panel
where the running carriage is located is not higher than
the other corner of the panel. If it is slightly lower (not
more than 1/16"), it is okay. Proper spacing is critical for
proper operation of the unit.
