VII. Venting
D. Design Requirements Unique to Split Vent Systems (continued)
Table 7.21: Summary of Split Vent System Options
* Specify size of B vent (e.g. 3PPS-BV
6
is for use with 6" B vent).
** Specify length in feet.
**** Specify Flex length and B vent diameter (e.g. IFBK02
2505
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. See equivalent
lengths for flex vent shown in Figure 7.14 and sizing example on page 32.
Note 2: At least 30" of CPVC pipe, and at least one CPVC elbow, must be installed between the boiler's vent connection and
PVC pipe.
Note 3: If masonry chimney contains flues in addition to that being used for chase,
ALL
must be unused.
Note 4: See vent manufacturer's installation manual for gaskets, spacers and other required vent components.
All vertical terminals require compatible roof flashing and storm collars.
