VERTICAL TERMINATION SYSTEMS (ROOF)
See Figure 19 and Figures 30 through
32 on Page 17 and their associated
Vertical Vent Tables, which illustrate the
various vertical venting configurations that
are possible for use with these appliances.
Secure Vent
®
pipe applications are shown in
these Figures; Secure Flex
®
pipe may also be
used. A Vertical Vent Table summarizes each
system’s minimum and maximum vertical
and horizontal length values that can be used
to design and install the vent components in
a variety of applications.
Both these vertical vent systems terminate
through the roof. The minimum vent height
above the roof and/or adjacent walls is
specified in ANSI Z223.1-2009 (In Canada,
the current CAN/CSA-B149.1 installation
code) by major building codes. Always
consult your local codes for specific
requirements. A general guide to follow is the
Gas Vent Rule (refer to Figure 5 on Page 6).
Vertical (Straight) Installation
(Figure 19)
Determine the number of straight vent
sections required. 4 1/2 in. (114 mm),
10 1/2 in. (267 mm), 22 1/2 in. (572 mm),
34 1/2 in. (876 mm) and 46 1/2 in. (1181
mm) net section lengths are available (see
Tables on this page and Pages 35 and 36—
Vent Sections). Plan the vent lengths so that
a joint does not occur at the intersection
of ceiling or roof joists. Refer to the Vent
Section Length Chart.
