Greenheck Concrete Floor with Steel Deck Supplement (463562) - Manual

Application
Horizontal installation of FD, DFD, DFD-2XX, FSD,
SSFSD, and CFSD models in concrete floors utilizing a
steel deck. The hole opening made through the concrete
floor may not allow the bottom angle to be placed against
the steel deck on an even plane. This installation details
how to properly install the required retaining angles next
to the steel deck.
For single side retaining angle installations refer to
Greenheck document number 474015: Single Side
Retaining Angle Installation Instructions Supplement.
Notes for Two-Side Retaining Angle
Installations
1. Retaining angles are required on top and bottom sides of
damper as detailed in the Installation Instructions shown
above. Legs on angles may be reversed such that one leg
is inserted into the floor opening provided the required
clearance is maintained between angle leg fasteners and
the floor opening.
2. Installation of the bottom retaining angle against the
uneven steel deck shall be done such that the angles
on each side of the sleeve are as close to the barrier as
possible. In other words, the angles on each side of the
sleeve may be in different planes relative to each other
(see Figure 1 and 2).
3. When viewed from end of sleeve, the angles must overlap
each other in the corners such that no sight-through is
possible (see Figure 2).
