1 RF-2000 Round Fire Damper Installation Instructions , Rev. C Part No , Rev. C Issued March 2016 Applications The RF-2000 round fire damper is designed to operate with blade running horizontally. Dampers can be vertically or horizontally installed with the leading edge of the closed blade within the wall or floor. To ensure optimum operation and performance, the damper must be installed so it is round and free from raking. Do not compress or stretch the damper frame into the duct or opening. Mounting - Vertical or Horizontal. Minimum UL Classified Size - 6 in. (152 mm) diameter. Maximum UL Classified Size - 24 in. (610 mm) diameter. 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). Refer to the QuickLIT Web site for the most up-to-date version of this document. Figure 1: Retaining Cinch Plate Dimensions, in. (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.

2 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.! 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. 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. Figure 2: Blade Orientation 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 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. 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 semiannually, 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. 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 tackfree before operating the damper. 2 RF-2000 Round Fire Damper Installation Instructions

3 Note: If opening size allows for angle on one side only, then sealant shall be applied on only angle side. Nothing is required on non-angle side. Installation Diagrams Figure 3 and Figure 4 illustrate installation in 1 and 2 hour rated masonry floors and ceilings or walls. Figure 4: Masonry Installation, Side View Figure 3: Masonry Installation, 3 Dimensional (3D) view Note: Masonry walls require retaining cinch plates on only one side of the wall, as shown.
