C. Design Requirements Unique to Vertical Venting Systems
Table 7.13a summarizes all vertical twin pipe vent options. Table 7.13.b summarizes vent options in which an abandoned
B-vent chimney is used both as a chase for the vent pipe and as a conduit for combustion air.
In addition to the requirements in Part VII-A, observe the following design requirements:
1. Permitted
Terminals
for
Vertical
Venting
Terminal Option H: Fittings (Acceptable for Vent Options 10-17) – Vent terminates in a plain end (coupling for PVC, bell end
\& & ^` "' %&'_''|
may be substituted). Observe the clearances from the roof, and normal snow line on the roof, shown in Figures 7.15 and 7.17.

Use of rodent screens is generally recommended for both terminations. Two rodent screens suitable for 3” PVC terminals
