DuraVent PolyPro Concentric Horizontal Termination: ends the vent through a wall with air intake around exhaust
The DuraVent PolyPro Concentric Horizontal Termination is the end piece for a vent that exits through an outside wall. Exhaust leaves through the center pipe, while air for combustion comes in around it. PolyPro is DuraVent’s polypropylene vent pipe for high efficiency condensing gas boilers, furnaces, and water heaters. The air openings face the ground to keep rain out. Screws at the connection keep the termination turned that way, but the cap itself must not point downward. The connecting end can be cut to suit the wall.
Choose a 2 by 4 inch, 3 by 5 inch, or 4 by 6 inch size on this page. The first number is the exhaust pipe size, and the second is the outer pipe size. Your appliance maker sets the allowed vent length and number of elbows. A qualified professional installs this part, and DuraVent recommends a yearly vent check. Need the adapters and plates too? See the DuraVent PolyPro Horizontal Termination Kit Concentric. The DuraVent PolyPro Concentric Horizontal Termination ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
