D. Copper Pipe Nom 3/4 in. diam (or smaller) regular (or heavier) copper pipe.

3. Tube Insulation — Plastics+ Nom 1/2 in. thick acrylonitrile butadiene/polyvinyl chloride (AB/PVC) flexible foam furnished in the form of tubing installed only on one pipe. The annular space between tube insulation and through penetrants (Item 2) shall be 1/2 in. The annular space between the tube insulation and periphery of opening shall be 3/8 in.See Plastics+ (QMFZ2) cateory in the Recognized Component Directory for names of manufacturers. Any Recognized Component tube insulation material meeting the above specifications and having a UL 94 Flammability Classification of 94-5VA may be used.

4. Firestop System The firestop system shall consist of the following:

A. Packing Material Min 3-3/4 in. thickness of min 4.5 pcf mineral wool batt insulation firmly packed into opening as a permanent form. Packing material to be recessed from top surface of floor or from both surfaces of wall or hollow-core floor as required to accommodate the required thickness of fill material.

B. Fill, Void or Cavity Material* — Caulk Min 3/4 in. thickness of fill material applied within the annulus, flush with top surface of solid concrete floor, or with both surfaces of wall or hollow-core floor. RECTORSEAL — Biostop 500+ Caulk
