DuraVent DuraPlus Factory-Built Chimney
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:
DuraPlus requires 2" clearance to combustibles. Outside Diameter is 4 inches larger than Inside Diameter.

Use this Wall Thimble when passing DuraPlus Chimney Pipe through an outside wall. It must be installed with a length of chimney pipe passing through it . This length connects to the Tee on the outside of the building. Then one of three adaptors are used to connect the appliance connector pipe.
Both 6" and 8" wall thimbles require a 14 1/2" X 14 1/2" framed opening.
The Attic Insulation Shield, left in picture, must be used when DuraPlus Chimney Pipe passes through an attic space. It centers the pipe providing clearance, has a built-in Firestop and prevents insulation from coming in contact with the chimney pipe. Includes a base and collar.
The Firestop Radiation Shield, right in picture, must be installed where a chimney pipe passes through a floor or ceiling without a round or square ceiling support box. Centers pipe and provides for proper clearances.
Roof Flashings provide leak proof roof penetration. Select the proper flashing based on the pitch of the roof.
Note that a 6/12 pitch has a vertical rise of 6" over a horizontal distance of 12".
We carry two flashings to accommodate most roof pitches: 0/12 to 6/12 and 7/12 to 12/12. These flashings require a Storm Collar (sold separately, shown on flashing in picture above).
