VII. Venting
D. Design Requirements Unique to Split Vent Systems (continued)
Table 7.21: Summary of Split Vent System Options (cont.)
* Specify size of B vent (e.g. 2PPS-BV6 is for use with 6” B vent).
** Specify length in feet.
**** Specify Flex length and B vent diameter (e.g. IFBK022505 includes 25ft of flex and used with 5” B vent).
Note 1: Max vent lengths shown also apply to the intake. Flex vent reduces the maximum allowable vent length in some
applications. See equivalent lengths for flex vent shown in Table 7.14 and sizing example on page 35.
Note 2: First 30” plus first exhaust elbow are CPVC.
Note 3: See vent manufacturer’s installation manual for gaskets, spacers and other required vent compone
nts
All vertical terminals require compatible roof flashing and storm collars.
