VERTICAL VENT FIGURES/TABLES Note: Secure Vent (rigid vent pipe) is shown in the figures; Secure Flex (flexible vent pipe) may also be used. WARNING: UNDER NO CIRCUMSTANCES MAY SEPARATE SECTIONS OF CONCENTRIC FLEXIBLE VENT PIPE BE JOINED TOGETHER.

Example: If 20 feet of (H) horizontal vent run is needed, then 4 feet minimum of (V) vertical vent will be required. - Page 16 D. Frame exterior wall opening - Locate the center of the vent outlet on the exterior wall according to the dimensions shown in Figure 9 on page 8. Cut and/or frame an opening, 10-1/2" x 12-1/8" (267 mm x 308mm) inside dimensions, about this center.
- Page 17 If the terminus of the last section is not within this distance, use the telescopic vent section SV4.5LA, as the last vent section. For wall thicknesses greater than that shown in Figure 28 , refer to Table 3 on page 18 . This table lists the additional venting components needed (in addition to the termination and adapter) for a particular range of wall thicknesses.
- Page 18 Note: Secure Vent components (rigid vent pipe and terminal) are shown in the figures; Secure Flex components (flexible vent pipe and terminal) may also be used. Note: Two 45 degree elbows may be used in place of one 90 degree elbow. The same rise to run ratios, as shown in the venting figures for 90 degree elbows, must be followed if 45 degree elbows are used.
