Simplify high-efficiency furnace installations with the DiversiTech CVENT-4 Concentric Termination Kit. Designed for 4-in. intake and vent piping, this concentric vent termination kit allows both combustion air intake and exhaust venting to pass through a single wall or roof penetration, saving time, labor, and materials compared to traditional installations that require two separate openings. The concentric design provides a cleaner, more professional finish while reducing the risk of water infiltration and minimizing the wall space needed. Built from durable materials for long-lasting performance, this concentric kit includes a combustion air inlet cap, air inlet pipe, vent pipe, and concentric Y fitting, giving HVAC professionals everything needed for reliable installation.
