Termination Options
Concentric vent kits allows for both exhaust and intake pipes to penetrate the roof or side wall through only one hole.

  • Molded cap with socket allows for vent screens and extensions. Cap can be mechanically fastened, allowing for quick removal and easy cleaning.
  • Integral fins prevent the cap from sitting flush to the wall, ensuring proper spacing needed for air flow.
  • Pipe-in-pipe design allows for single wall penetration resulting in fewer holes to core & seal.
  • Short branch on the Wye makes for a stronger fitting which can be installed in tighter spaces.
