Application
Horizontal installation of FDR, SSFDR, DFDR, SEDFDR,
SSDFDR, FSDR, SEFSDR, SSFSDR models in concrete
floors utilizing a steel deck. The hole opening made
through the concrete floor may not allow the bottom
plate to be placed against the steel deck on an even
plane. This installation details how to properly install the
required retaining plates next to the steel deck.
Notes
1. Damper assemblies must be installed in wall/floor
openings using a single retaining plate on either side
of the wall/floor. The use of a second retaining plate is
allowed, but is not necessary. A single retaining plate is
provided with the dampers. A second retaining plate can
be ordered as an option.
