DuraVent DuraPlus Factory-Built Chimney

hiflex ovaltornd.jpg dvdp group.jpg

DuraVent's DuraPlus 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. 

DuraPlus is listed to the UL 103HT Standard and carries an impressive limited lifetime warranty.

DuraPlus is available in 6" and 8" inside diameters.  Outside diameters are approximately 4" larger than inner.  The DuraPlus inner liner is 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. 6", 9" and 12" lengths have galvanized steel outer walls. 

DuraPlus components twist-lock securely into place and are stainless steel unless otherwise noted.  When double-wall black stovepipe is needed with DuraPlus use DuraVent DVL.

According to the manufacturer, Dura/Plus performs three very important functions:

  1. It stays cool on the outside to protect the home during normal stove operation.
  2. It stays hot on the inside to discourage the deposit of creosote and provide the correct draft for stove efficiency.
  3. It has a fire safe design that allows the hot metal to flex and expand while it cools the chimney.

DuraPlus requires 2" clearance to combustibles. Outside Diameter is 4 inches larger than Inside Diameter.
