A newly designed metallic vent elbow from this leading venting system and chimney liner manufacturer uses standing seam construction to withstand extra stress. The Z-Vent elbow is made with AL29-4C super ferritic stainless for extra strength and resistance to corrosion. It's backed by a 15-year warranty. Pipe fusion welds give a smoother finish and fit for easier installation. It also has double fail-safe joints and a 1 in. clearance from combustibles.
