Installation Instructions
The installation of the WD66 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 WD66 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 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. Confirm whether the unit
ordered is WD66/o, top-hung or WD66/u, floor supported.
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, that means 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.
• For certain configurations with even number of
panels on a side, separate running posts.

NANAWALL WD66 OWNER’S MANUAL

• Upper and lower running carriage sets – one set for
each pair of folding panels. (An extra set for each pair
or multiple pairs of folding panels unhinged to a side
jamb or other panels).
• A certain amount of hinge pins and set screw to
secure the hinge pins.
• 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, some resistance to water
infiltration may be achieved by installing drain
connections to the outside. See Diagram 2.

NANAWALL WD66 OWNER’S MANUAL

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.
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 waterborn 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 described in
Step A8 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 are
provided in segments, then connect them first. 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
Make sure that the stainless steel insert for the sill of
floor supported WD66/u are in the correct place
(Illustration A1).
Step A3
For top-hung WD66/o L/R with unhinged pairs of panels
not connected to a side jamb, see Step B7. The upper
running carriage has to be inserted in the head track
before assembling the frame.
Step A4
Assemble all frame parts as shown. Do not apply sealant
to the corner joints yet.

INWARD OPENING
Step A5
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 A6
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 A8
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. For Florida installations, please
see Appendix B for specific installation 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

TOP-HUNG LOW PROFILE SADDLE SILL
For resistance against wind driven rain,
recommend the following by others:
1. Remove the gasket covering the inner
water channel.
2. Provide necessary weep holes at
bottom of channel and through to the
outside face of the sill.
3. Make necessary drain connections.

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 A9
For the top-hung WD66/o and for the floor supported
WD66/u anchor the sill to the subfloor.
The sill has to be installed 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.
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.

Step A10
Anchor the side jambs to studs or walls. Make sure that
the jambs are plumb and straight.
Be aware that the anchorage points in the side jamb with
the lesser number of panels attached to it may in Step C6
need to be loosened to be able to move the side jamb to
adjust the total width of the unit.
Step A11
As the sill is attached first, then the side jambs, now
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 A12
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. See
Illustration A3.
B. PANELS AND FOLDING HARDWARE
INSTALLATION
IMPORTANT: Look for glass stops to determine the
interior side of a panel.
Step B1
On top-hung WD66/o insert all the upper running
carriages into the upper track, through the slot on
one end of the head jamb. The lower running carriage
functions as a guide in the sill. See also Diagram 2.
On floor supported WD66/u insert all lower running
carriages into the sill. See Illustration B1. The upper
running carriage is just a guide in the upper track. See
also Diagram 2.
Step B2
Looking at the elevation drawing, first install panel(s)
hinged to the side jamb(s). Align the hinge components
on the panel to the hinge components on the side jamb
and insert the proper hinge pin. Insert the hinge pin in a
way such that the security set screw fit into the groove in
the hinge pin. Loosen the set screw as needed to insert
the hinge pin, tighten till it touch the pin and then back o
a full turn. Use an Allen key. See Illustration B2.
