DuraVent PolyPro 45 Degree Elbow: a gentle turn around indoor obstacles
The DuraVent PolyPro 45 Degree Elbow is a vent fitting that turns the pipe around an indoor obstruction. This gray elbow makes a gentler bend when a beam, duct, or other obstacle is in the way. PolyPro is DuraVent’s polypropylene vent pipe for high efficiency condensing gas boilers, furnaces, and water heaters. One locking clamp comes with the elbow to secure the joint. Choose the size that matches your vent: 2, 3, 4, 5, 6, or 8 inch.
A horizontal vent needs to slope back toward the appliance without low spots that can hold condensate, the moisture left as exhaust cools. That lets the water return to the appliance or reach a drain. The appliance maker specifies how that water must drain and sets the allowed vent length and number of elbows. Those limits matter when planning a route around an obstacle, so each turn needs to be part of the vent plan. Need a sharper turn? See the DuraVent PolyPro 90 Degree Elbow. The DuraVent PolyPro 45 Degree Elbow ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
