The DiversiTech® CVENT-3-EXT is a 3 in. concentric termination kit that simplifies installation for high efficiency furnances by only requiring one hole through the wall or roof where the pipes terminate. Without using the installation would require cutting two holes through the home (one for each pipe). This vent saves time and money by reducing the amount of work required. The kit includes combustion air inlet cap, air inlet pipe, vent pipe and intake/vent concentric Y.

• Without using these vents the installation would require cutting two holes through the home
• Allows the intake for combustion air and the exhaust vent to pass through a standard roof or sidewall
• Available in 2in, 3in, or 4in intake vent sizes.
