Every joint on polypropylene vent piping must include
a locking collar.
DO NOT use cellular core PVC (ASTM F891), cellular core
CPVC, or Radel®(polyphenolsulfone) in venting systems.
DO NOT cover non-metallic vent pipe and fittings with

the boiler and at terminations, if required.
ADAPTERS — If using 2”piping, where approved for the
application, provide adapters for the 3” PVC boiler con-
nections and at the terminations, if required.
ALL vent and air pipes require a BIRD SCREEN at each termination. Most kits do not include
the bird screens. Purchase bird screens separately from Williamson-Thermoflo or vent kit sup-
plier if not included. [Note — bird screening is integral to the 3” PVC W- T sidewall vent cap,
available for purchase from Williamson-Thermoflo .No additional screening is required.]
