Revision 35M-IN-2007A
Each operator should be allowed to perform and follow through to completion each
similar operation in proper sequence in stead of performing numerous other unrelated
operations.
In laying out aisle lines and chair sizes, always work from the center line to of the
building towards walls.
All parts of theater chairs are specified as “right” or “left” as a person sits in the chair.
Do not unpack parts until ready to distribute them. Keep various kinds of hardware in
their individual packages.
Sloped Floor Layout
Locate center line of building by entering
between side walls at rear and front
Spacing of chair rows: Locate the chair
size line for each row on the established
centerline of the building. This is the
center line shown on the seating plan for
each row of chairs (fig. 2). For the
spacing of rows, follow the
measurements shown on the seating plan.

Revision 35M-IN-2007A
Important: This work must be done accurately as the arcs of the other rows are
determined from the arc of the first row or row for which the template is given.
Layout chair size lines
Place a T-square on the base circle so that the working edge is along the center line and
the two corners of the cross piece touch the base circle. Mark the next three or four chair
size lines. Continue this along the entire arch at intervals approximately 18” apart.
Draw and arch through the points previously marked off, using a flexible strip
approximately 12’ long. It is recommended that the strip be bent in a curve, with a man
holding each end and one man bending the strip and marking the arc. Continue the arc
through the remaining points using the flexible strip. Let the strip overlap the arch
already drawn by approximately 3’ in order to insure a smooth curve.
Repeat for the successive rows towards the rear of the room. NOTE: In working toward
the rear of the room, the arc of each successive row flattens slightly. To maintain
uniform row spacing, occasionally check distance between rows and relocate you row
spacing reference mark on your T-square.
Lay out chair sizes and aisles
On the chair size line, lay out the chair sizes in accordance with the seating plan, starting
at the center line of the building. The end allowance stated on the seat plan is the
2
Revision 35M-IN-2007A
distance from the middle of the end standard to the aisle, step, or other obstruction.
NOTE: First establish chair sizes for the front and rear rows in order to insure straight
alignment of aisle standards.
In circular arrangements, the end standard nearest the center of the building usually
intersects the aisle line at the rear of the armrest (rear point of alignment). The end
standard on the opposite side of the aisle usually intersects at the front of the arm rest
(front point of alignment). Refer to Figure 3.
From the points of aisle alignment (at the front and rear rows), snap a chalk line for one
side of the aisle. Establish the width of aisles at the front and rear, corresponding to the
measurements shown on the seating plan. These widths are given square to the aisle and
to the points of aisle alignment. See Figure 3.
Figure 3
After the aisle width has been established, lay out the chair sizes in the intermediate rows.
Using a smaller T-square, draw a line perpendicular to the chair size line, this line will be
your seat size line. Seat size is measured from middle of standard to middle of standard.
NOTE: Floor layout for straight rows requires the same general method as for curved
rows except that the chair size lines are straight.

Revision 35M-IN-2007A
Floor Mount Chair Installation
Use an actual middle and end standard or template to mark the location of floor hardware.
Refer to Figure 4 for an example of the relation between the mounting holes and the chair
size line and chair width line. Standards may vary, refer to detail on seat plan.
Figure 4
For wood floors, use four ¼” x 2 ½” wood screws. Run screws through predrilled holes.
Pre drill 5/32” for soft wood and 3/16” for hard wood.
For concrete floors, use two concrete anchors, lead or chemical adhesive. Only two
anchors are required per standard using opposite holes when possible.
For steel floors, use two ¼” x 1” thread forming “Taptite” screws per standard through
7/32” predrilled holes.
Riser Mount Layout
In straight rows, the chair sizes are laid out directly on the riser face. On curved rows,
the chair sizes must be maintained on the chair size line, which is offset from the face of
the riser. Offset distance will be noted on seat plan.
The end standards must be located so the desired aisle width will be obtained. The
seating plan shows the “end allowance”, which is the distance from the centerline of the
end standard to the furthest point of end, protruding into aisle.
Check the riser length and compare to seat plan. When laying out the row, be sure to
center on riser. Layout the first and last row before intermediate rows, this will insure
proper aisle alignment throughout the room. NOTE: The seating plan normally allows 1”
extra space per row for making adjustments.
Riser Mount Installation
Before locating the center of holes for drive anchors, check the riser height for uniformity
throughout the row. If the riser height is not uniform, select the high point and mark hole
locations from this point. If the risers are out of plumb, notify the contractor. The ACI
tolerance for plumbness is 1/8” in 10”. Contact American Seating for instructions on
how to proceed.
4
Revision 35M-IN-2007A
Drill holes in the risers. Refer to Figure 5 for examples of hole locations. Refer to the
seat plan for actual hole sizes.
Figure 5
Before installing anchors, make sure the holes are cleaned out thoroughly. You may need
to refer to the anchor manufacturer’s specs for installation instructions.
Be sure the head of the bolt is at the bottom of the hole before caulking to avoid the lead
sleeves wedging in the hole. This can be done by pushing the anchor in with the caulking
tool. If the anchor sticks, lightly tap the end of the bolt, forcing the head to the bottom of
the hole and then push the lead sleeve down. Caulk until the anchor gives a solid metallic
sound to indicate that the anchor has been properly set.
To install on steel risers, use two (2) 3/8-16 x 1-1/2” thread forming “taptite” screws per
standard. Drill 11/32” diameter lead holes.
Erect standards:
Hang standards in position, apply the flat washers, lock washers, and hexagon nuts.
Tighten both bolts sufficiently to hold the standards in an upright position. The anchor
bolts cannot be securely tightened at this time because it will interfere with the assembly
of the backs.
Assemble Backs to Standards
Distribute backs. Sizes are shown on carton.
To attach backs to middle standards, start at one end of the row and insert ¼” ribbed neck
carriage bolt through the top and bottom holes of the back and through the holes in the
standard.
NOTE: Be sure to use the correct holes in the backwing and standard to obtain the correct
back pitch as shown on the seat plan.
The ¼” bolt will extend through the adjacent back and allows sufficient length to install a
lock washer and hex nut. This operation to be repeated until the row is completed.
5
Revision 35M-IN-2007A
Tighten upper and lower bolts securely. Be sure standard is vertical before tightening
back bolts.
Break off end of bolts with bolt breaker or piece of tubing with ¼” or 5/16” inside
diameter.
Place cover caps over hex nuts and tap with hammer until cover cap is properly seated.
To attach backs to end standards, remove ¼” machine screws which were included with
the standard, place them though the proper holes in the back and place back in position to
start the screws into the end standard.
NOTE: It is important to refer to the seating plan in all cases to determine the back pitch.
It must be noted that the back pitch is an important factor in vision, spacing, and comfort.
At this point, take the time to tighten all floor and riser attachments. Tighten each screw
or anchor nut with the proper tool to the recommended tension.
Installation of Seats
Distribute seats. Sizes are shown on carton. The 35M seat has multiple seat pan sizes
and pivot configurations. Refer to Figure 6 to identify different seat pan configurations.
The identification to find out how many inches less the seat is from the chair size is stated
on the chair summary of the seat plan.
It is recommended to start at the right end of each row.
Insert bolt assembly through top of hole in right end standard and assemble nut about
three turns. Lift bolt and place right seat pivot on shelf of standard. Swing left side of
seat until pivot rests flat on shelf of next standard. Loosely insert bolt assembly as
before. With the next seat, place the right pivot under the left pivot of the previous seat
and place right pivot on next standard. Continue this for the entire row. Since the left
pivot on a seat is higher than the left pivot, place a spacer under the left pivot on the last
seat. This will ensure the last seat is level.

Before tightening seats, examine the pivot positions carefully. Seats must be centered
uniformly between the standards to obtain maximum contact between lower pivot ear and
pivot landing and a maximum overlap of upper pivot ear over lower pivot ear. If contact
is less than 1”, carefully pry pivot away from seat pan with a screwdriver. Pivots must be
aligned to the seat pan with sufficient clearance to prevent rubbing. Use provided spacers
between pan and pivot to maintain clearance when tightening seat bolts.
Seats in tablet arm chairs are ½” off center, with a 1” extended seat pivot on the left hand
side, but proper engagement of pivots as described above must be provided.
Use a right angle power driver or hand socket wrench to tighten the nuts from the bottom.
If installer elects to install the seats by tightening the bolts from the top with an extension
on a power driver, he must upon completion retighten the nuts from the bottom with a
ratchet or box wrench to a minimum torque of 35 foot pounds.
Finish Repair
Any damage to the finish of standards must be touched up. This is usually around the
attachment hardware or anywhere that paint has been chipped. Air dry acrylic enamel is
supplied for this purpose.
Attachment of Armrests
Wood:
Place arms on standards so that the routings in the arms come down over the arm lugs on
the standards. Strike each arm directly on the front edge with the palm of the hand so
that the arms will be wedged on enough to stay in place. Drive on arm rests an additional
¾” using a padded block and mallet.
When driving arms on, stand behind the row being worked on and place pressure against
standard to relieve stress on floor anchors.
Plastic:
Place a spring clip over the rear lug on the standard and align with standard. Tab should
be pointed to the read and bent up. Place armrest over lugs and push back. The tab on
the spring clip will snap into the lug hole on the armrest.
To remove the armrest, use a small screwdriver and force the metal tap (spring clip)
down. While holding clip down, drive the armrest to the front of the standard.
Shoe and Stretcher Installation
Refer to seat plan to determine placement of removable seat assemblies. Layout
removables before fixed seating is laid out. Using the mounting bracket as template,
mark holes for the floor anchors, drill and set. Attach standards to shoes and attach shoes
to floor.

Power and Date Installation
The seat plan provides a list of the parts required for installation. Review the plan to
identify the parts. The installation requires the following major components: raceway,
connection box (if required), brackets and assembly hardware, outlet and end covers. A
licensed electrician will be responsible for any electrical wiring or hook ups. Power and
Data may be added to beam, riser, and floor mount chairs with a 23’ or greater radius.
The following chart indicates the maximum number of wires allowed in each raceway.

Mounting Bracket
The mounting bracket will replace the flat washer in the bolt assembly attaching the seat
pivot to the standard, Please refer to Figure 7 and 8 below. Once the brackets are
installed, it is time to install the electrical connection box if supplied. If this box is not
supplied, the electrical wiring will connect directly to the raceway. The following steps
will not be necessary in this instance. This box will house the wiring coming from the
floor and the connections to the wiring in the raceway. Place the connection box at the
end of the raceway. Be sure to place box so that the raceway terminates into the side of
the box and the box covers the stub up locations. Drill holes in the box and mount to the
floor using anchor bolts.

Raceway
If a connection box has been installed, butt the end of the raceway against the side.
Attach the pull box mounting bracket to the connection box with two #10 – 16 x ¾ self
drilling pan head screws. Fasten the raceway to the pull box mounting bracket with two
¼-20 T nut assemblies. Figure 9.
If the power will feed through the front of the raceway, start the raceway approximately
8” outside of the first middle standard in the row.
If the raceway does not extend 8” beyond the center of the last middle standard in the
row, then cut the raceway at the center of the nearest mounting bracket.
Attach the raceway to each mounting bracket with the T nut assemblies. Insert one T nut
in each slot on the back of the raceway. Hold the raceway against the mounting brackets
and center vertically. Slide the T nut assemblies into the slots in the mounting bracket
and tighten the bolts. Continue until all mounting brackets are attached. Cut raceways so
that all splices lie in the middle of the mounting brackets. Figure 10.

Figure 10
Raceway Covers
Outlet and data covers will be centered on each middle standard. To ensure each sitting
has an outlet and data jack, there will be a plug no less than 1.25” and no more than 3”
from the nonpower feed. Place all the covers over the raceway centering them between
standards. At each middle standard there will be a gap between the covers between 2.5”
to 6” long. This will be covered with the outlet cover at a later time. Covers may have to
be trimmed to maintain gaps along the run and trimmed down at the ends. Once all
raceway covers are on, place the end covers on with the provided #6 screws. Refer to
Figures 11 and 12.

Outlet Covers
To install the outlet cover, center it on the gap created by the raceway covers. Hook the
flange into the groove on the top of the raceway. Secure the cover to the center flange of
the raceway with the provided #10 screw. NOTE: One outlet cover per chair. Figure 13.
