c. All CPVC/PVC vent and combustion air
pipe joints must be cleaned with primer and
glued with cement. Follow all manufacturer
instructions and warnings when preparing pipe
ends for joining and using the primer and the
cement.

Vent Piping
Running PVC vent pipe inside Enclosures
and through Walls:
• PVC vent pipe must be installed in such
way as to permit adequate air circulation
around the outside of the pipe to prevent
internal wall temperature rising above
ANSI Z21.13 standard specified limit.
• Do not enclose PVC venting. Use higher
temperature rated CPVC pipe in enclosed
spaces or to penetrate combustible or non-
combustible walls.
• PVC vent pipe may not be used to
penetrate combustible or non-combustible
walls unless all following three conditions
are met simultaneously (see Figure 12):
-
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 12 is maintained around
outside of the vent pipe to provide
air circulation
• If above three conditions cannot be met
simultaneously, use CPVC for the wall
penetration.
• Size and cut wall opening such that a
minimal clearance is obtained and to allow
easy insertion of vent pipe.
• Apply sealant between vent pipe and wall
