Installation
Notes
Use the following notes as guidelines when installing
this product.
1. Opening Clearance: A square opening in wood or
metal stud walls or masonry walls and floors shall
be a minimum of 1 in. (25 mm) and a maximum of
2-1/2 in. (64 mm) larger than the damper diameter.
A round opening in masonry walls or floors shall
be a minimum of 1 in. (25 mm) and a maximum of
2-1/2 in. (64 mm) larger than the damper diameter.
2. Damper Sleeve: The sleeve is integral to the
damper and shall be equal to or heavier than the
gauge of the duct as described in National Fire
Protection Association (NFPA) standard NFPA90A
and as defined by the appropriate Sheet Metal and
Air Conditioning Contractors’ National Association
(SMACNA) duct construction standard.
3. Retaining Cinch Plates: Place retaining cinch
plates around the damper sleeve and cinch against
the sleeve with the screw provided on the cinching
device (see Figure 1). The plates are designed to
grab and hold the sleeve while mounting flush
against the wall or floor, retaining the damper
securely in the opening. The plates must overlap
the opening a minimum of 1/2 in. (13 mm).
Fasten the cinch plates to the wall or floor
according to the following:
• Masonry Wall – Cinch plate required on only
one side of the wall fastened to the wall with a
minimum of 1-1/4 in. (32 mm) #10 masonry
screw.
• Masonry Floor – Cinch plate required on both
sides of the floor fastened to the floor with a
minimum of 1-1/4 in. (32 mm) #10 masonry
screw.
• Metal Stud Wall – Cinch plate required on only
one side of the wall fastened to the wall by
engaging the metal stud a minimum of
1/2 in. (13 mm) with a #10 screw.

RF-2000 Round Fire Damper Installation Instructions2
• Wood Stud Wall – Cinch plate required on both
sides of the wall fastened to the wall by
engaging the wood stud a minimum of
1-1/2 in. (38 mm) with a #10 screw.
4. Damper Orientation: The leading edge of the
blade in the closed position must be within the
plane of the wall. Vertical installation is illustrated
and horizontal is similar. (See Figure 3 through
Figure 6.) The damper may be installed with up to
a 30 degree variance of the axle being horizontal.
The damper is approved with airflow in any
direction.
5. Duct/Sleeve Connections: Round breakaway
connections must be used. Either a 4 in. (102 mm)
wide draw band or #10 sheet metal screws spaced
equally around the circumference of the ducts as
follows:
• duct diameters of 22 in. (559 mm) and smaller
– three screws
• duct diameters over 22 in. (559 mm) to 24 in.
(610 mm) – five screws
Note: When optional sealing of these joints is
desired, the following sealants may be applied in
accordance with the sealant manufacturer's
instructions:
• Hardcast, Inc. – Iron-Grip™ 601 sealant
• Precision - PA2084T
• ECO Duct Seal 44-52
• Design Polmerics - DP1010
Note: Install the damper so that it is square and free
from raking. Compressing or stretching the damper
frame into the duct or opening may result in failed
operation and will void the warranty.
6. Optional Sealant of Dampers in Fire Rated Wall
or Floor Openings: Following the sealant
manufacturer's directions, remove dirt, grease, and
moisture from the surface to be sealed. Apply a
continuous bead of sealant to the location
applicable to your specific installation.
Approved sealant or fire stop materials:
• Dow Corning® - 999A, Silastic 732RTV
• GE® - RTV 108
• Hilti Corporation - FS-One
• 3M® - #M-CP 25WB+
• Specified Technologies, Inc. - SpecSeal®
Series SSS or LCI
• John Manville International, Inc. - Firetemp™
CI
• Rectorseal - Metacaulk 1000, Metacaulk 350i,
Biostop 500+ or Biostop 350i
Do not apply sealant within the required expansion
gap between the damper and the fire rated wall or
floor.
Press the surface of the sealant in place to dispel
any air. Allow sealant to set up and become tack-
free before operating the damper.
!
WARNING: Risk of Personal Injury.
Do not place cinch plates in the groove. If
the cinch plates are in the groove, the
damper is not properly secured. An
insecure damper may dislodge and fall,
which may result in severe personal
injury or death.
AVERTISSEMENT : Risque de
blessure.
Ne pas placer les plaques de retenue
dans la rainure. Si les plaques de retenue
se trouvent dans la rainure, le registre
coupe-feu n'est pas correctement fixé.
Il pourrait alors sortir de son logement et
de tomber, ce qui risque de provoquer
des blessures graves, voire mortelles.
Figure 2: Blade Orientation
IMPORTANT: Do not lift the damper using the
blades or actuators. Lift or handle the damper using
the frame or sleeve. Handling or lifting the damper
by the blades or actuator may damage the damper
and will void the warranty. Do not compress or
stretch the damper frame into the duct or opening.
IMPORTANT: Examine each smoke damper on a
regular basis to ensure it is not rusted or blocked. In
addition, test each smoke damper annually or semi-
annually, depending on the application, and
according to the National Fire Protection Association
(NFPA) standards, to ensure it will perform as
intended. Exercise care to ensure that such tests
are performed safely and do not cause system
damage.
