VERTICAL INSTALLATION, cont.

Step 8.

Twist-lock the vent cap and seal.

Note:

(1)For multi-story vertical installations, a ceiling firestop (SDV part #963) is required at the second floor, and any subsequent floors (Figure 16). The opening should be framed to 10” x 10” (254mm x 254mm) inside dimensions, in the same manner as shown in Figure 13.

(2)Any occupied areas above the first floor, including closets and storage spaces, which the vertical

vent passed through must be enclosed. The enclosure may be framed and sheetrocked with standard construction materials; however, refer to these installation instructions for the minimum allowable clearance between the outside of the vent pipe and the combustible surfaces of the enclosure. Do not fill any of the required air space with insulation.
