DuraVent PolyPro Test Port: gives a technician access to test the exhaust
The DuraVent PolyPro Test Port is a short vent section that sits directly above the appliance. A technician unscrews its small cap to check the exhaust and see how the appliance is burning, rather than drilling a hole in the vent. One locking clamp is included. Choose a 2, 3, 4, 5, 6, or 8 inch size on this page. PolyPro is DuraVent’s polypropylene vent pipe for high efficiency condensing gas boilers, furnaces, and water heaters.
Straight PolyPro pipe can be shortened with a hacksaw, leaving a square end with any rough edges removed. Cutting removes the clamp tab, so that joint is held by a locking clamp or locking band clamp. Screws must never pierce the pipe wall. In the USA, the appliance maker must list PolyPro for that appliance, and its venting instructions govern its use. In Canada, DuraVent lists PolyPro as a vent system in its own right. Need a drain fitting near the appliance too? See the DuraVent PolyPro Condensate Drain fitting. The DuraVent PolyPro Test Port ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
