Extend cast-iron <br />sleeve fittings below floor slab as required to secure clamping ring if ring is <br />specified. <br />b.Install sleeves in new walls and slabs as new walls and slabs are constructed. <br />c.Install sleeves that are large enough to provide 1/4-inch (6.4-mm) annular clear space <br />between sleeve and pipe or pipe insulation. Use the following sleeve materials: <br />1)Pipe Sleeves: For pipes smaller than NPS 6 (DN 150). <br />2)Steel Sheet Sleeves: For pipes NPS 6 (DN 150) and larger, penetrating <br />gypsum-board partitions. <br />3)Stack Sleeve Fittings: For pipes penetrating floors with membrane <br />waterproofing. Secure flashing between clamping flanges. Install section of <br />cast-iron soil pipe to extend sleeve to 2 inches (50 mm) above finished floor <br />level. Refer to Division 07 Section "Sheet Metal Flashing and Trim" for flashing. <br />4)Seal space outside of sleeve fittings with grout. <br />d.Except for underground wall penetrations, seal annular space between sleeve and <br />pipe or pipe insulation, using joint sealants appropriate for size, depth, and location of <br />joint. Refer to Division 07 Section "Joint Sealants" for materials and installation. <br />DocuSign Envelope ID: ECCAC5A0-6CC8-4B37-8AD3-89D69F0AE1AE
