DuraPlus Triple Wall All Pipe
DuraPlus chimney is specifically engineered to maintain a cool exterior while creating a hot and efficient draft on the inside. This triple-wall chimney is constructed with two insulating layers, one made of ceramic blanket and the other of air space. The ceramic blanket insulation is securely held in place, effectively eliminating hot spots that are commonly found in loose-fill type insulations. In the event of a fire caused by creosote, the compressible blanket insulation allows the chimney liner to expand outwardly in a radial direction. With the ability to operate at 1000°F flue gas temperatures, DuraPlus chimney is rigorously tested to meet the stringent HT requirements of the UL standard. This includes one hour at 1400°F, plus three ten minute chimney fire tests at 2100°F. DuraPlus chimney is suitable for use with wood stoves, fireplaces, furnaces, boilers, stoves, ranges, water heaters, or other appliances fueled by wood, oil, coal, or gas. It is constructed with an outer wall made of .016″ 430 stainless steel or .018″ galvanized steel, an intermediate liner made of .018″ aluminized steel, and an inner liner made of .016″ 430 stainless steel. It is insulated with ceramic blanket and ventilated air space. The precision twist-lock connection ensures a tight lock. Clearances of 2″ are required for combustibles. The diameters available are 6″-8″. DuraPlus chimney is UL Listed to UL 103HT (MH7399). Refer to the Typical Venting Installation drawings provided by the manufacturer to select the appropriate component parts for your installation. For installation of DVL or DuraBlack stovepipe to a Ceiling Support, Wall Thimble, or Finishing Collar, a DVL/DuraBlack Chimney Adapter or DuraBlack Slip Connector is required. When connecting snap-lock stovepipe to DuraPlus, a Snap-Lock Adapter must be used. To accommodate thicker walls, a wall thimble extension can be field fabricated with a Wall Thimble. An Attic Insulation Shield must be used in all installations that pass through an attic, regardless of whether the attic is insulated or not. If the chimney is enclosed in a chase in the attic space, an Attic Insulation Shield is not required. When a chimney passes through a floor or ceiling without a Ceiling Support Box, a Firestop Radiation Shield is mandatory.
