DuraVent PolyPro Concentric Telescoping Vent Length: adjusts to fill gaps a fixed length cannot
The DuraVent PolyPro Concentric Telescoping Vent Length is an adjustable section of concentric vent pipe. It slides in or out to fill a gap where a fixed length would not fit. Once its length is set, the included sheet metal screws hold it at the sliding connection and at both ends. 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 on this page to match your vent.
The connections push together over a gasket, a seal inside the receiving end of the pipe. Those receiving ends face away from the appliance, toward the vent outlet. Instead of a locking band, two included self tapping screws secure the outer pipes at each connection. Your appliance manufacturer determines the allowed vent length and number of elbows, so this adjustable section still needs to fit that plan. Need a fixed section instead? See the DuraVent PolyPro Concentric Vent Length fixed pipe. The DuraVent PolyPro Concentric Telescoping Vent Length ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
