Description
DuraPlus® is designed to stay cool on the outside, to provide a hot draft on the inside, to boost stove efficiency, and to provide for a fire-safe design that protects both the chimney and the building. This triple-wall chimney features two insulating layers (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°F flue gas temperatures, DuraPlus® subjected to rigorous and stringent HT requirements of the UL standard, including one hour at 1400°F, plus three ten minute chimney fire tests at 2100°F.
Kit includes: DVL and DuraBlack Chimney Adapter, Snap-LockAdapter w/ Trim, 9” DuraPlus Chimney Pipe (galvanized), WallThimble, Tee w/ Cap, (2) Wall Strap, Tee Support Bracket, andChimney Cap. Only available in 6” diameter. Use for through-the-wall installations.
