Vertical Termination Systems (Roof)

See Figure 20 on Page 12 and Figures 28- 32 on Pages 15 and 16 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; 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-1 B149 installation code) by major building codes. Always consult your lo- cal codes for specific requirements. A general guide to follow is the Gas Vent Rule (refer to Figure 5 on Page 5 ).

Vertical (Straight) Installation

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 Table 11 and Page 31 - Item 3). 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.
