IV. Venting
B. CPVC/PVC Venting (continued)
• PVC vent pipe may not be used
to penetrate combustible or non-
combustible walls unless all following
three conditions are met simultaneously
(see Figure 15):
-
The wall penetration is at least 66
in. (1680 mm) from the boiler as
measured along the vent
-
The wall is 12 in. (300 mm) thick or
less
-
An air space of at least of that shown
in Figure 15 is maintained around
outside of the vent pipe to provide
air circulation
• If above three conditions cannot be
met simultaneously when penetrating
a combustible wall, use CPVC pipe for
wall penetration.
• Size and cut wall opening such that a
minimal clearance is obtained and to
allow easy insertion of vent pipe.
Figure 15: Wall Penetration Clearances
for PVC Vent Pipe
• Apply sealant between vent pipe and wall
opening to provide weather-tight seal.
Sealant should not restrain the expansion
of the vent pipe.
• Install contractor provided optional trim
plate on wall outside surface to cover
wall opening (see Figure 15).
• Secure trim plate to wall with nails or
screws and seal ID and plate OD or
perimeter with sealant material.
