OPTIONS
The Simpson Dura-Vent DirectVent
Pro offers a complete line of
component parts for both horizontal
and vertical installations. Many
items are offered in decorative black
as well as galvanized nish. The
galvanized pipe and ttings may be
used for concealed locations such as
attics, or spaces where corrosion is
a factor, such as above the rooine.
Decorative black painted sections
are recommended for use on visible
interior runs. Snorkel Terminations
are available for applications which
may require vertical rise on the
building exterior.
PLANNING YOUR
INSTALLATION
There are two basic types of
DirectVent Pro installations. Check the
appliance manufacturer’s installation
instructions to conrm what types
of installations are permitted and
check for any venting restrictions
such as maximum horizontal run, and
minimum or maximum vertical rise.
The two types of installations are:
• Horizontal Termination (Figs. 1 and 2)
