4.Partially assemble vent kit.
a.Cement Y concentric fitting to larger diameter kit pipe. (See Figure 20).
b.Cement rain cap to smaller diameter kit pipe. (See Figure 21).
5.Install concentric Y fitting and pipe assembly through the structure’s hole and
6.Install rain cap and small diameter pipe assembly in concentric Y fitting and large pipe assembly. Ensure small diameter pipe is cemented and bottomed in concentric Y fitting.
7.Secure assembly to structure as shown in Figure 23A. Ensure clearances as shown in Figure 23A.
