VERTICAL TERMINATION SYSTEMS (ROOF)
See
Figure 17 and Figures 25 through 27 on
Page 16 and their associated Vertical Vent Tables
which illustrate the various vertical venting con
-
figurations 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/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 17)
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
30 - 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.
Note: Convert inches into metric equivalent
measurement, as follows:
Millimeters (mm) = Inches x 25.4
Centimeters (cm) = Inches x 2.54
Meters (M) = Inches x .0254
