Simpson DuraPlus HTC Chimney System - All-Fuel Chimney for Canada
DuraPlus HTC is a double-wall, all-fuel chimney system designed for Canada for use with wood stoves; fireplaces; and appliances using wood, oil, gas, or coal. Thermal Tech II insulation encased between inner and outer walls of .020" 430 stainless steel. Thermal Tech II Blanket insulation is made of light-weight silica-ceramic. This insulation will not shrink or cause gaps like products made of mineral wool or other loose-fill insulations. Encased between two stainless steel walls, the insulation maintains a barrier that will not shift or settle. The 2" wall keeps the exterior cool, while ensuring high temperatures for optimum draft performance on the outside. Locks tightly with a precision twist-lock connection. Simpson DuraPlus HTC carries a limited-lifetime warranty.
2" clearance to combustibles.

Using the Typical Venting Installation drawings (below), select the appropriate component parts for your installation.
A DVL/DuraBlack Chimney Adapter must be used when connecting DVL or DuraBlack stovepipe to a Ceiling Support, Wall Thimble, or Finishing Collar.
A Wall Thimble must be installed with an appropriate section of chimney pipe for all horizontal through-the-wall installations. To accommodate thicker walls use a wall thimble extension.
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 chimney is enclosed in a chase in the attic space, an Attic Insulation Shield is not required.
A Firestop Radiation Shield must be used when a chimney passes through a floor or ceiling without a Ceiling Support Box.
A Roof Radiation Shield is required at the roof deck penetration.
-Maintain at least a minimum 2" clearance (air space) to combustibles. Use proper support and bracing. Follow local building codes and have your chimney inspected by a certified professional.
- The diameter of the chimney should match the outlet size of the appliance. An improperly sized chimney results in poor draft and excessive creosote formation.
- Measure the diameter of the appliance flue outlet. Select the chimney and either DVL or DuraBlack connector stovepipe with the same size diameter as the appliance flue outlet. For fireplace installations, call us.
- Determine if the installation is a through-the-roof installation or a through-the-wall installation. A through-the-wall installation will require additional components (Wall Thimble, Tee w/ Cap, Tee Support, and Wall Straps).
- Install the chimney in the interior of the structure whenever possible. A cold exterior chimney will produce less draft and will generate more creosote.
- If possible, avoid offsets that serve to restrict the natural draft.
- Determine the minimum chimney height above the roof line. Check your local building codes for proper installation.
