The Z-Vent is one of the only metallic gas vent pipes that can be cut to length on site. Designed for boilers, high-efficiency furnaces, pool heaters, unit and water heaters, it is made of AL29-4C super ferritic stainless and comes with a 15-year warranty against corrosion. The new design of the Z-Vent makes installation easier and also leads to higher performance. Pipe fusion welds give a smoother finish and provide a better fit. Every length is adjustable and Z-Vent also features double fail-safe joints and one inch clearance from combustibles.
