VERTICAL TERMINATION SYSTEMS (ROOF)
See Figure 15 and Figures 23 through 25 on
Page 18 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. 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.
The vertical vent system terminates through
the roof. The minimum vent height above the
roof and/or adjacent walls is specified in ANSI
Z223.1—latest edition (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 8).
Vertical (Straight) Installation
(Figure 15)
Determine the number of straight vent sections
required. 4-1/2" (114 mm), 10-1/2" (267 mm),
22-1/2" (572 mm), 34-1/2" (876 mm) and
46-1/2" (1181 mm) net section lengths are
available (see Tables on this page and Page
32—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.
