VERTICAL TERMINATION SYSTEMS (ROOF)
See Figure 19 and Figures 29 through 33
on
Page 17
and their associated Vertical
Vent Tables, which illustrate the various
vertical venting configurations that are
possible for use with this appliance.
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/CGA-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 4
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. 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.
