With the louver section sitting level inside the wall opening, place
the Retaining Angles (A-5) in the positions shown in Figure 3. The
Retaining Angles should be tight against the rear surface of the wall
(the wall will be “sandwiched” between the Mounting Clip flanges in
front and the Retaining Angles behind.)
For each Mounting Clip, drill 9/32'' clearance holes for 1/4'' hard-
ware through both the clip and the adjacent Retaining Angles (as
well as the sleeve, if present). These holes should be located no
closer than 3/8'' to the rear edge of either the Mounting Clip or the
Retaining Angle. Side-to-side spacing is not critical but should be
approximately even.
Use 1/4'' Hex Bolts (F-5), 1/4'' Hex Nuts (F-4) and Flat Washers
(F-2) to bolt the Mounting Clips and the Retaining Angles together,
using the clearance holes drilled in step 8 above.
Finally, install backer rod and caulk around the entire perimeter of
the louver, as required.

Single Section Louver Installation (cont.)
Install Hat Channel Clips and Mounting Clips on all sections
following steps 1-2 for single-section louvers.
If a sleeve is required, attach a Sleeve-Side Plate only to the left-
hand side of the left-most section in the opening (as viewed from
the exterior), following step 3 for single-section louvers. Also, attach
a Sleeve Side Plate only to the right-hand side of the right-most
section (mirroring the left section). If no sleeve is needed, omit this
step and proceed directly to the next task below.
Lift the section up and place it into the opening. For a sleeve, insert
Sleeve Top and Bottom Plates between the Mounting Clips and the
opening as shown in Figure 6; otherwise, refer to Figure 3. Shim as
required to level the section and to maintain an approximate 1/4''
clearance between the louver frame and the edges of the opening
(shims are by others).
Attach Retaining Angles to the left section as described in steps 7-
9 for single-section louvers.
As shown in Figure 6, press the I-mullion seam cover onto the right-
hand jamb of the left section (again as viewed from the exterior).
The I-mullion may require tapping with a rubber mallet to properly
seat into place.
Using the procedure described above, install the next section to the
right leaving approximately 1/4'' between sections. If a sleeve is
required, place Sleeve Top and Bottom Plates between the
Mounting Clips and the opening before installing the Retaining
Angles.
Moving sequentially from left to right, follow the same method to
install any remaining I-mullions and louver sections.
Finish by installing backer rods and caulk around the entire
perimeter of the opening, as required. If the louver includes a
sleeve, be sure to caulk any seams between sleeve plates.
