Factory Sleeve Option All fire damper installations require the use of sleeves, angles and methods described in the installation instructions. Sleeves can be field fabricated or factory furnished as a completed damper/sleeve assembly. Sleeves are galvanized steel and are available in 20 through 10 ga. (1mm.5mm) thicknesses and lengths up to 6 in. (914mm). K dimension specifies location of damper within the sleeve. Minimum is 4 in. (102mm), maximum is L less 4 in. (102mm), which allows for mounting angle installation, and duct connection at each end of the sleeve. If K dimension is not specified, it will be provided as one half of L dimension (damper centered in sleeve). Note: If using access doors, the door should be installed on the K side of the damper. Sleeve Damper K Damper CL Damper Frame Location L Overall Sleeve Length Sealed Option When sealed option is selected, B transition will need to be field sealed in the area where duct to sleeve connection is made. Type B with sleeve Seal this area.
Type A, B, & B2 Dampers larger than maximum single section sizes are supplied in 2 or more sections of equal size. If ordered with a factory sleeve, multisection dampers are factory assembled ready for installation. If ordered without a factory sleeve, multisection dampers require field assembly.
