bottom section(s), taking into consideration the alignment of all pieces. The installer may require
some bracing. It is important to ensuring both sections are straight, even, and parallel to each other.
To add strength, use multi-section brackets. Mullion end caps may be used when linkages are to be
kept free of dirt and debris (see two sections wide)

1) Shims shall be used between the damper frame and the duct aperture or opening gap to avoid the
frame from being distorted by the bolts that hold it in line. To reinforce for strength, brace every
horizontal mullion and every 8 feet of damper width vertically. High-velocity dampers (2000 fpm
[10.2 m/s]) could require further bracing. Alumavent dampers are built and engineered specifically
for structural integrity dependent on model and conditions. The installer is responsible for
attaching, framing, mating flanges, and anchoring damper assemblies into apertures, ducting, or
walls. Field engineers should determine the design calculations for these retaining and supporting
that particular installation.
2) The extension pin should extend roughly 4-6 inches (102-152mm) beyond the frame if the damper
actuator is to be installed out of the air stream. For jackshaft units, the jackshaft should extend
through the jackshaft bearing assembly and approximately 6 inches (152mm) beyond the frame for
jack shafted units.
3) Individual damper sections, as well as entire multi-section assemblies, need to be square and
without racking, twisting, or bending. Measure each portion diagonally from the upper corners to
the opposite bottom corners.
4) Damper blades, axles, and linkage must all function freely. Cycle dampers after installation to ensure
good operation before starting the system. All portions of a multi-section assembly should open and
close at the same time.
