DuraVent DuraPlus 6 Diameter Stainless Steel Chimney Pipe

The DuraPlus system from DuraVent is designed to stay cool on the outside provide a hot draft on the inside and boost stove efficiency, offering a fire-safe design that protects both the chimney and building. This Stainless Steel Triple-Wall Chimney Stove Pipe features two insulating layers consisting of a ceramic blanket plus air space. The ceramic blanket insulation is held securely in position, eliminating hot spots common with loose-fill type insulations. In the event of a creosote fire, the compressible blanket insulation permits the chimney liner to expand outwardly in a radial direction. Designed for normal, continuous operation at 1000 虋F flue gas temperatures, DuraPlus is subjected to rigorous and stringent HT requirements of the UL standard, including one hour at 1400 虋F, plus three 10-minute chimney fire tests at 2100 虋F.
