DuraVent PolyPro Single Wall Pipe: straight gray pipe for an indoor vent run
The DuraVent PolyPro Single Wall Pipe is a straight, rigid pipe that forms most of an indoor vent run. It is gray. PolyPro is DuraVent’s polypropylene vent pipe for high efficiency condensing gas boilers, furnaces, and water heaters. Choose your vent size, then its length. The 2, 3, 4, 5, and 6 inch sizes come in 12, 36, or 72 inch lengths. The 8 inch size comes in 40 or 75 inch lengths. Each length includes a locking clamp, which DuraVent requires at every joint.
The pipe can be shortened with a hacksaw, leaving a square cut with rough edges removed. Cutting removes the clamp tab, so a locking clamp or locking band clamp secures that joint. Screws must never pierce the pipe wall. Wall straps carry the vent’s weight, not the appliance. They support horizontal, sloped, and vertical sections, with one near each elbow or tee. A firestop belongs at each floor and ceiling crossing, including the attic floor but not the roof deck. Need outdoor pipe? See the DuraVent PolyPro Black UV Resistant Single Wall Pipe for outside. The DuraVent PolyPro Single Wall Pipe ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
