Installation Instructions
The installation of the SL45 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 aluminum
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 SL45 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. 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.
• Screws to connect the four corners of the frame.
• Hinge pins and screws.
• 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.
NANAWALL SL45 OWNER’S MANUAL

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.
PREPARATION OF THE ROUGH OPENING
For necessary clearance and adjustment space, rough
opening is suggested to be 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.
PLEASE NOTE – 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.
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.
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
A7 before assembling the frame.
Step A1
Lay the four frame components flat on the floor and align
the ends to be connected.
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.
NANAWALL SL45 OWNER’S MANUAL

5
Step A2
Apply exterior grade sealant to all connection points between the frame components. The ends of the sill should be
completely filled with sealant to prevent water leakage from the ends of the water channels on the sill. All drilled holes and
fastener screws have to be sealed too.
Step A3
If a unit is ordered with a standard or a flush sill, assemble all frame parts as shown in Diagram 1.
NANAWALL SL45 OWNER’S MANUAL

L
R
Step A4
If the unit is ordered with a low profile saddle sill, then the side jamb rest on top of the sill. On the end of the sill are end
dams with two flanges, which slide into the slots on the outside of the vertical side jambs. Screw them together with the
provided screws.

6
Step A5
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 A6
Temporarily secure the frame to the rough opening with clamps.

and other details for specific
surrounding conditions
must be properly designed
and provided by others.
Drawings not to scale. Details shown are subject to change without notice.

Step A7
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'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
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
predrilled 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.
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.
DIAGRAM 3:
SUGGESTED FRAME FASTENING POINTS
A = About 4"from the interior edge.
B = Distance about 16", except at the stacking area on
one or both sides where spacing should be about 4".
Plus extra screws at meeting point of panels.
C = Distance about 14"from the bottom using extra screw
at top.
See Appendix B for Florida installations. Step A8.
NANAWALL SL45 OWNER’S MANUAL

NANAWALL SL45 OWNER’S MANUAL
Step A8
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 A9
Anchor the side jambs to studs or walls in the same
manner. Make sure that the jambs are.
Step A10
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 A11
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. Use the
brush provided.
B. PANELS AND FOLDING HARDWARE
INSTALLATION
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. Slide the rod and open the plate.
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. The security set screws on
the hinges have to be loosen with an Allen key before
inserting the hinge pins, tighten them till they touch the
pin and then back off a full turn. See also Illustration C1.
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 proper 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.

9
NANAWALL SL45 OWNER’S MANUAL
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 4. 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 1/4” 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.
Step C5
Check all vertical joints:
Make sure that the side jambs are still vertically straight.
All vertical spacing between side jamb and panel, panel
and panel should be 5/16". If necessary, the hinges can be
adjusted. Adjust across the length of the unit and at all
hinges at a pivot point, not just in one place.

NANAWALL SL45 OWNER’S MANUAL
Step C6
If the horizontal spacing are still not correct, try by
adjusting the glass setting blocks that are bracing the
glass in the panel. Remove the gasket and glass vertical
stops from the panel. See Appendix A for the correct
location of the setting blocks. The panel can be raised
by increasing the thickness of the upper vertical setting
block and lowered by decreasing this thickness. The lower
vertical setting block will have to be adjusted accordingly.
Glass suction cups may be needed to raise the glass
up for easier placement of the setting block. The panel
frame will rack up or down at the appropriate corners with
adjustments of the setting blocks. Adjust as needed to
obtain the correct spacing and re-install the glass stops
and gasket. See Appendix A for further details on glazing.
Step C7
Check that the system operates and functions properly.
The panels should be able to be moved easily by one
person without much eort (for not more than 6 panels
to one side) when opening or closing and all shoot bolts
should engage smoothly. If the panels do not move easily
or a lot of eort is needed, the indication is that the unit
is not properly installed. Correct any problems before
finish trimming.
Step C8
Apply a thick bead of exterior grade sealant with a backer
rod if needed on the joint between the sill and sub floor
on both sides along the length of the sill. Do similar for
the gaps between the head jamb and side jambs with
the opening.
Step C9
Finish any waterproofing, flashing, trim,and sealant
needed around the perimeter of the opening.
IMPORTANT: Make sure any weep holes in the sill
are not blocked.
Step C10
To prevent uncontrolled movement of the panels when in
open position, place appropriate door holder by others as
needed.
PROTECTION OF UNIT DURING
CONSTRUCTION PHASE
It is important that during the construction phase
the unit be kept closed, covered and protected from
damage. During this phase, a unit is often subject to the
most extreme conditions from all types of construction
operations that can permanently damage and destroy
it. A unit can be damaged by cement splatter, tar, paint,
weld splatter, falling objects, construction dust, sand
blasting, etc. All temptations to use the large opening
of an installed system for easy ingress and egress by
tradesmen should be resisted.

NANAWALL SL45 OWNER’S MANUAL
RECOMMENDED MAINTENANCE OF
NANAWALL PRODUCTS
Some General Considerations on all Projects:
1. It is important that the product is installed correctly.
A poorly installed unit will not function properly.
This will cause more abnormal force or stress on
the components and will lead to premature failure.
When operating the unit, the panels should generally
be able to be moved easily by one person (except
when there are very large panels or when there are
more than 6 panels folding to one side). All locking
points should engage smoothly. There should be no
rubbing on the floor and no binding. When the unit is
closed, the reveal between panels and head jamb and
between panels and sill should be consistent. There
should be no daylight seen from the inside. Please
have all problems corrected as soon as possible by a
qualified technician.
2. From time to time, due to building movement or
settlement, a unit may need to be adjusted by a
qualified technician to compensate for any building
change.
3. It is important that a unit is operated properly.
Locking points should be gently opened and closed
and not forced. Panels should be opened and
closed in the proper manner and sequence. See the
Operation section for proper operation.
4. Periodically check for worn or damaged components
and replace as soon as possible. A unit with
nonworking components will subject the other
components to increased stress and lead to
premature failure. A unit with worn or damaged
components will compromise the performance level
expected for air and water infiltration, structural
loading and forced entry.
5. Periodically, inspect the sealant/caulking on the
exterior perimeter of the unit. It is extremely
important that the sealant/caulking remains intact
and in good condition. Trim off any old, loose
caulking, and seal any gaps with a good quality caulk.
6. Check that all weep holes are clean and clear of any
obstructions. Remove debris and other foreign bodies
which have dropped into the tracks in the head jamb
and sill immediately to prevent damaging the running
carriages and guide trolleys. Clean all components as
needed. Check gaskets for proper seating and
condition. Remove dust and any deposits from these
gaskets.
7. The finished aluminum or wood surface needs
periodic cleaning and maintenance. Its appearance
may be marred by harsh chemicals, abuse,or neglect.
Frequency of cleaning depends on exposure and
needs. For aluminum surfaces, generally warm soapy
water should be sufficient. Stubborn stains and
deposits may be removed with mineral spirits. For
wood surfaces, superficial surface dirt can be
removed by washing with water and a soft-bristled,
long-handled brush. Heavier accumulations can be
removed with a mild solution of household detergent.
For all surfaces, aggressive alkaline or acid cleaners
should not be used. Excessive abrasive rubbing
should be avoided. Sealants and weather stripping
may be affected by strong organic solvents.
Superficial damage to the aluminum surface must be
touched up immediately with proper touch up paint.
8. If it is a wood product, the surface should be visually
inspected every six months or earlier, depending on
the exposure of the NanaWall unit. Periodically
repaint or restain the wood as needed. Exposure to
the environment will break down the finish and
compromise its protective features if not refinished.

14
See Finishing Recommendations in the Owner’s
Manual of the wood systems.
9. All hardware, hinges and handles should be
periodically cleaned with a soft cloth and mild
cleanser. Excessive abrasive rubbing should be
avoided. Please note that oil rubbed brass is a finish
that will develop its own unique patina over time.
10. About every six months, apply lubricant to all the
hinges and Teflon spray to the running carriages and
guiding trolleys.
SOME SPECIFIC SUGGESTED MAINTENANCE
FOR COASTAL SALT WATER AND OTHER
EXTREME ENVIRONMENTS:
Please note that the environment within one mile of a
sea coast can be extremely corrosive. Products installed
in this environment will typically deteriorate sooner than
products installed in a less severe environment.
1. Open and close completely a unit at least once a
week and inspect all surfaces.
a. Salt and other corrosive or abrasive materials
such as sand must not be allowed to build up on
any surfaces, including all hardware and sill.
b. The sill and head jamb tracks should be free from
all dirt and debris.
c. There should be no standing water in the track
in the sill.
d. All hardware should be intact and operating
properly.
2. All surfaces must be cleaned with a mild detergent
soap and fresh water at least every month and more
frequently if necessary.
a. After washing, the surface should be rinsed
thoroughly with clean water and allowed to dry.
b. For cleaning, do not use abrasive household
cleaners or materials like steel wool or hard
brushes that can wear and harm finishes.
c. Any glass cleaner used should not be allowed to
run down on any other surface.
3. Any breaches in the paint coating, such as scratches,
chips or areas of abrasion, must be repaired
immediately.
4. Every 3 months, thoroughly clean and dry all upper
and lower rollers and all hinges. Liberally apply
lubricant such as Teflon spray (no grease) on the
wheels and bearings of the rollers. Oil all hinges
including the hinge pin with light weight lubricating
oil or Teflon spray.
5. As with any painted surface exposed to corrosive
environments, every 6 months apply a wax to the
outside of the painted panel and painted track. If the
system includes corner connections make sure the
wax penetrates the connection joints.

15
NANAWALL SL45 OWNER’S MANUALAPPENDIX A
GLASS INSTALLATION AND GLAZING
This section applies only if you need to install glass for
any reason or if glass setting blocks need to be adjusted.
Proper glass installation is critical, as, with the NanaWall
folding system, glass is a structural part of the panel.
Glass stops and glazing gasket are to be used for “dry”
glazing of each panel. Also needed are setting blocks.
Use glass setting blocks with varying thickness made
from hard plastic. Rubber setting blocks are not
acceptable. Width of setting blocks should be at least 1/8"
wider than the glass thickness and 1/16"to 1/8"less than
the width of the glazing pocket.
Glass, with appropriate dimensions, thickness and
specifications will be needed. Depending on the model,
widths of all glass panels may not be equal. Please note
that glass is required to be fully tempered unless the unit
is a window placed above a certain height from the floor.
Check with all applicable codes and regulations.
Float glass, including the glass components of insulated
glass, shall meet the current requirements of ASTM C
1306 “Standard Specifications for Flat Glass” for quality,
thickness and dimensional tolerances. Tempered float
glass shall meet the current requirements of ASTM C
1048 “Standard Specifications for Heat-Treated Flat
Glass - Kind HS, Kind FT Coated and Uncoated Glass.”
All tempered glass shall have a permanent logo, which
signifies Safety Commission 16 CFR-1201 and the safety
glass test requirements of ANSI Z 97.1 (current editions).
Insulating Glass shall meet the requirements of ASTM E
774, Class A, B or C.
Although glass installation with the “dry” glazing system
is relatively straight forward, it is recommended that an
experienced glazing contractor be used.
It is very important that the bracing direction and
placement of glass setting blocks on opposite diagonal
corners be correct. Setting blocks are to be placed only
at opposite diagonal corners with corners alternating with
each succeeding panel. This is necessary for the stability
and balance of the panels when in operation. If not
correctly braced, the unit will not operate properly.
The general rules for bracing are as follows:
• For a panel attached to a side jamb, the lower brace
should be at the lower corner.
• closest to the side.
• For a panel with a running carriage, the lower brace
should be on the lower corner that is on the same
side as the running carriage.
• For a swing panel, the lower brace should be at the
lower corner away from the stile with the locking
hardware. See Diagram 1 for an example of setting
block locations.
Follow all proper applicable glass installation and glazing
techniques as recommended in the Flat Glass Marketing
Association (FGMA) “Glazing Manual” and “Sealant
Manual”. Always use suction cups to shift glass within an
opening. It would be best to install the glass on the panels
before they are installed in the opening. Panels can be laid
flat on sawhorses. If the panels are already installed, they
can still be glazed.
1. Close all panels and secure them with the multiple
point lock bolts. Start with a panel that is attached to
a side jamb or, in the case of unhinged pairs, closest
to a side jamb.
2. Remove all glass stops on the panel. Be sure to
protect the finish.

16
NANAWALL SL45 OWNER’S MANUALAPPENDIX A
3. Measure both the vertical and horizontal dimensions
of the glass and the panel opening. Subtract the
vertical glass size from the vertical panel opening
size. Divide the difference by two. This will give the
nominal thickness of the setting block to use at the
top and bottom rails. Several setting blocks of
different thickness may need to be combined to
obtain the desired thickness. Do the same for the
horizontal dimension to obtain the thickness of the
setting block to use at the stiles.
4. Place a setting block (or combination of setting
blocks with desired thickness) on the bottom rail of
the panel opening such that it is about 2"from the
bottom corner as determined by the bracing rules
above.
5. Carefully place the glass in the opening, making sure
it rests on the setting block. With insulated glass,
make sure that both inner and outer panes are
supported evenly.
6. Place a second setting block in the same corner as
the first setting block, but in the vertical direction
along the stile such that it is about 2" above the
corner.
7. Place another setting block in the upper diagonal
corner vertically on the opposite stile in the same
manner. If necessary, apply a little adhesive that is
non-damaging to the glass edge seals such as Dow
Corning 791 silicone, to keep the vertical setting
blocks from slipping.
8. Place the last setting block on the upper rail on the
same corner as the other upper setting block. To get
a proper fit, shift the glass weight by lifting the panel
up with a plastic pry bar at the lower corner below the
upper setting block. These setting blocks should all
fit snugly but should not be forced.
Adjust the thickness of the glass setting blocks such
that the panel is slightly out of square. The upper
corner with the setting blocks should be about 1/16"
higher than the other corner.
If the panels are large, additional setting blocks may
be needed midpoint on the stiles, especially on a
swing panel.
9. For aluminum systems insert the glass stops so that
they snap into the panel profile. For wood systems
insert the glass stop firmly into position, so they are
flush with the panel. Nail to the inner side of the panel
with small finish nails. Start with the top and bottom
stops and then the sides.
10. Insert the glazing gasket in the space between the
glass and the glass stop. First, cut the gasket to a
length a little longer than the actual length of the
glass stop because gasket material may shrink at low
temperatures. Do not stretch or pull the gasket in any
manner. If necessary, use soapy water to lubricate the
gasket to make insertion easier.
11. Make sure that the stops are locked firmly and
securely into position and are flush with the rest of
the panel profile.
12. Repeat Steps 2 to 12 for each of the other panels.
Setting blocks for each succeeding panel must be
placed at diagonally opposite corners in the proper
sequence as set forth in Step 1. See Diagram 1 for an
example of a three panel unit.

NANAWALL SL45 OWNER’S MANUALAPPENDIX A
13. After installing the panels, assuming that the head
jamb and sill are level, check to see if the gap
between the panel and head jamb and panel and sill
is even across the width of the panel. With the glass
weight, the out of square panels should become
almost even. If they remain slightly higher in the
upper corner with the setting blocks it is okay. If not,
then the lower and upper setting blocks thickness
need to be adjusted. Panels have to be braced
correctly for proper operation.
