Additional Information:
The Simpson DuraPlus all-fuel chimney system is for use with wood stoves, fireplaces, furnaces, boilers, stoves, ranges, water heaters, and other appliances fueled by wood, oil, coal, or gas. The innovative triple wall construction is designed to stay cool on the outside, and provide hot drafts on the inside to boost stove efficiency which in turn, makes for a fire-safe construction that protects both the chimney as well as the building. The triple wall chimney features 2 insulating layers. A ceramic blanket and air space provide security to the design. The ceramic blanket insulation is held securely in position eliminating hot spots common with loose-fill type insulations. In the event of a creosote fire, the compressible blanket insulation allows the chimney liner to expand outwardly in a radial direction.
DuraPlus components make for easy installations offering a precision twist-lock connection that secures without the use of gaskets or sealants. Safety and efficiency of the chimney is maintained after the installation with a 2" minimum clearance to combustibles.
