VERTICAL TERMINATION SYSTEMS (ROOF)
See Figure 25 and Figures 35 through 39
on Pages 21 and 22 and their associated
Vertical Vent Tables which illustrate the various
vertical venting configurations that are possible
for use with these appliances. Secure Vent
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 speci-
fied 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 8).
Vertical (Straight) Installation
(Figure 25)
Determine the number of straight vent sec-
tions 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 40 - Rigid 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
NOTE: Attic insulation shield (H3907,
see Page 41) must be installed when
blown or loose-fill insulation is used,
and is required for all attic installa-
tions.
