Diversitech CVENT-3, PVC, 3″ Concentric Vent Kit

CVENT-3 with express delivery. For use with 3 inch intake/vent systems. PVC concentric vents make it easier on high efficiency furnaces to have a 2 pipe installation. The CVENT-3 is the 3 inch pipe version. Simplifying the installation process, this pipe uses just one vent hole through the wall or roof, compared to the usual 2, making installation and appearances better. This pipe allows for the intake for combustion air and the exhaust to be installed in a normal roof or sidewall. Do not use the Concentric Vent kit for anything other than a category IV furnace.


  • Intake/vent pipe size: 3 inch
  • Overall assembled length: 39-3/4 inches

DiversiTech’s CVENT-3 concentric vent kit includes all fittings a contractor will need to install the vent. No additional fittings for outside connections are needed. Only piping from the vent kit to the furnace will need to be provided separately.
