DuraVent PolyPro Concentric Vertical Termination: ends the vent straight up through the roof
The DuraVent PolyPro Concentric Vertical Termination is the roof outlet for a concentric vent. It stands upright, with the included support clamp wrapped around it. Concentric means a pipe inside another pipe. The polypropylene inner pipe carries exhaust out, while the powder coated aluminum outer pipe brings combustion air in. This lets both pass through one roof opening instead of two. PolyPro is DuraVent’s polypropylene vent pipe for high efficiency condensing gas boilers, furnaces, and water heaters.
Choose 2 by 4 inch, 3 by 5 inch, or 4 by 6 inch. The first number is the exhaust size, and the second is the outer pipe size. Joints push together over a gasket, a seal inside the receiving end, which faces toward the termination. Two included self tapping screws hold the outer pipes together at each joint, without a locking band. Roof flashing, the piece around the roof opening, is sold separately. Choose adjustable flashing for 0/12 to 5/12 roofs, steep flashing for 5/12 to 12/12, or flat roof flashing. Have a steeper roof? See the DuraVent PolyPro Concentric Steep Roof Flashing. The DuraVent PolyPro Concentric Vertical Termination ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
