VERTICAL TERMINATION SYSTEMS (ROOF)
See Figure 18 and Figures 27 to 31 and their
associated Vertical Vent Tables illustrate the
vertical venting confi gurations that are allowed
to be used with these appliances. Secure Vent
pipe applications are shown in these fi gures;
Secure Flex pipe may also be used. See Page
24. 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. In the USA, the minimum
vent height above the roof and/or adjacent walls
is specifi ed in ANSI Z223.1 (latest edition); in
Canada, by the current CAN-1 B149 installation
code. It is also specifi ed in major building codes.
Always consult your local codes for specifi c
requirements. A general guide to follow is the
Gas Vent Rule (refer to Figure 4 on Page 7).
Vertical (Straight) Installation
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 Table 10 and Page 31 - Item
3). Plan the vent lengths so that a section joint
does not occur within the space defi ned by
ceiling joists or roof rafters. Refer to the Vent
Section Length Chart.
