Use only the adapters and vent system listed in Tables 12 and 13.
DO NOT mix vent systems of different types or manufacturers.
Failure to comply could result in severe personal injury, death, or
substantial property damage.
Installations must comply with applicable national, state, and
local codes.
Installation of a polypropylene vent system should adhere to the
vent manufacturer’s installation instructions supplied with the
vent system.
All terminations must comply with listed options in this manual
and be a single-wall vent offering.
The installer must use a specific vent starter adapter at the
flue collar connection. This adapter is supplied by the vent
manufacturer to adapt to its vent system. See Table 13 for
approved vent adapters. Do not use CPVC starter piece.
All vent connections MUST be secured by the vent manufacturer's
joint connector (Figure 20).
Insulation should not be used on polypropylene venting
materials. The use of insulation will cause increased vent wall
temperatures, which could result in vent pipe failure.
