ABSTRACT:
A firestop stub-out assembly (10) adapted to be mounted through fire rated wall members (100, 102) to prevent the spread of fire between rooms in a building through the stub-out assembly, is described. The assembly includes a non-flammable, cast iron insert (12), having an annular flange (12c) at one end, with the sleeve mounted inside of a flammable, plastic sleeve (14). The insert is locked inside of the sleeve by a plastic coupling (16) that mounts over and around the flange of the insert. The coupling provides a connection means for the sleeve to a water operated fixture and to fluid conduits (30, 32) mounted between the walls. The water trap (218) is mounted between the water operated fixture and the sleeve and prevents air from entering the conduits through the water operated fixture.
