F. Rigid Non-Metallic Conduit + — Nom 2 in. Diam (or smaller) PVC conduit installed in accordance with Article 347 of the National Electrical Code (NFPA 70).
G. Electrical Nonmetallic Tubing+ — Nom 2 in. (or smaller) PVC tubing installed in accordance with Article 331 of the National Electrical Code (NFPA 70).

4. Firestop System — The firestop system shall consist of the following:
A. Packing Material — Foam backer rod firmly packed into opening as a permanent form. Packing material to be recessed from top surface of subfloor and bottom surface of the lower top plate as required to accommodate the required thickness of fill material.
B. Fill, Void or Cavity Material* - Caulk — Min 1/4 in. thickness of fill material applied within annulus, flush with top surface of subfloor and min 1/2 in. thickness of fill material applied within the annulus, flush with bottom surface of lower top plate. At point contact location, 1/4 in. diam bead of caulk applied at interface of pipe and periphery of opening on top surface of floor and bottom surface of lower top plate.
