INSTALLATION OF VENT SYSTEM, SIDEWALL
With the route of the venting system and selection
of
materials completed, as discussed in the section of this
manual titled "Planning The Vent System", the through-the-
wall vent terminal in place and the first section of piping,
up to first elbow, installed at the rubber coupling, it is time
to complete the installation of the venting system for the
sidewall installation.
Before completing the installation of the venting system
be sure to read the sections of this manual discussing the
proper method of cutting and cementing PVC pipe and
fittings in the "Vent Pipe Preparation" section.
It is recommended
that the completion
of the venting
system start at the rubber coupling and run to the coupling
on the inside wall of the vent terminal (see Figure 23).
