Tee w/Cap - SS 6" Dura/Plus Stainless Steel Tee With Cover - Dura-Vent's Dura/Plus is an all fuel, triple-wall chimney that combines one layer of ceramic refractory blanket insulation and an airspace to keep the outside wall cool. This also keeps the inside wall hot, boosting efficiency. Dura/Plus is listed to the UL 103HT Standard and carries an impressive 25-year warranty. The outside diameter is approximately 4" larger than it's inside dimension. Dura/Plus features inner liner construction of 430-alloy stainless steel with a middle wall of aluminized steel. 24" and 36" chimney lengths are available with either stainless steel or galvanized steel outer walls. Dura/Plus components twist lock securely into place and are stainless steel unless otherwise noted. According to the manufacturer, Dura/Plus performs three very important functions; It stays cool on the outside to protect the home during normal stove operation. It stays hot on the inside to discourage the deposit of creosote and provide the correct draft for stove efficiency. It has a firesafe design that allows the hot metal to flex and expand while it cools the chimney. Dura/Plus requires 2" clearance to combustibles.
