DuraVent PolyPro Concentric Vent Length: straight pipe between the appliance and the vent outlet
The DuraVent PolyPro Concentric Vent Length is a straight section of vent pipe that runs between the appliance and the outlet at the wall or roof. PolyPro is DuraVent’s polypropylene vent pipe for high efficiency condensing gas boilers, furnaces, and water heaters. Concentric means one pipe sits inside another. The inner polypropylene pipe takes exhaust out. The outer pipe is powder coated aluminum, and the space around the inner pipe brings in air for the appliance to burn. This arrangement needs only one opening through the wall or roof, rather than separate holes for exhaust and incoming air.
Choose the diameter pair and length together on this page. Sizes are 2 by 4 inch, 3 by 5 inch, and 4 by 6 inch, each in 500 or 1000 millimeters. The first diameter is the exhaust pipe, and the second is the outer pipe. Cutting is allowed only when a label on the male end, which fits into the next section, specifically permits it. Without that label, the section must stay uncut. Need an adjustable section? See the DuraVent PolyPro Concentric Telescoping Vent Length adjustable pipe. The DuraVent PolyPro Concentric Vent Length ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
