Vertical (Roof) Termination Systems
This section includes configurations for verti-
cal (roof) termination systems with either
straight vertical venting (see below and Page
23) and offset vertical venting (see Page 23).
Secure Vent rigid vent pipe and termination
®
components are shown in the figures.
The tables on Page 23 summarize each sys-
tem's minimum and maximum vertical and
horizontal length values.
For vertical (roof) termination, the minimum
vent height above the roof and/or adjacent
walls is specified in ANSI Z223.1, latest edi-
tion (in Canada, the current CAN/CGA-B149.1
installation code) and by major building
codes. Always consult your local codes for
specific requirements. A general guide to
follow is the Gas Vent Rule (see Figure 4 on
Page 11).
Vertical Termination System
with Straight Vertical Venting
NOTE: If not already done, install the
provided vent restrictor before proceed-
ing (see Page 19).
Determine the number of straight vent sec-
tions required. Available straight vent sec-
tions (and their effective lengths) are listed
in Table 7, below. See Page 35 for all venting
components.
Plan the vent lengths so a joint does not occur
at the intersection of ceiling or roof joists.
Refer to the "VENT SECTION LENGTHS"
charts at right.
