Notes:
1. PVC can only be used on the exhaust of a boiler after 10 linear feet of CPVC pipe. All fittings within the first 10 feet
must be CPVC. See Figure 23, page 26 .
2. For CPVC/PVC , See Figure 96, page 105 for SlimFit adapters to connect boiler connection to CPVC/PVC pipe.
Every joint on vent and air piping must include a locking collar. Failure to supply locking collars could result in vent/air piping
leakage. All PVC and CPVC joints should be permanently joined using the suitable primer and cement for the vent material.
DO NOT USE: Cellular core PVC (ASTM F891), cellular core CPVC, or Radel® (polyphenolsulfone) pipe or any other material
not listed in the table above.
DO NOT mix piping from different pipe manufacturers unless using adapters specifically designed for the purpose by the
manufacturer.
