These tables reflect the parts required if using special venting system for both exhaust vent and air intake pipe system.
If using ABS/PVC/CPVC material for combustion air intake pipe, (refer to table 22 for proper starter adaptor for the system).

Note: For combination of different vent/air intake pipe diameters, such as Ø 3 in. stainless steel vent with Ø 2 in. (CVPC, PVC,
ABS) air intake pipe, the total equivalent length must be used for the smaller pipe diameter. See tables 24, 25 and 26.
