DuraVent DuraChimney II 8 to 16 inch Wall Strap: holds the chimney away from walls

The DuraVent DuraChimney II 8 to 16 inch Wall Strap is a bracket that steadies your chimney beside a wall or inside a chase, the enclosure around the pipe. It maintains a 2 inch air gap without carrying the whole chimney’s weight. DuraVent calls for a strap at least every 8 feet of height. Inside a chase, a stabilizer can take its place. DuraChimney II is DuraVent’s air cooled chimney, a double wall pipe in 8 to 16 inch sizes for fireplaces that burn wood, oil, coal, or gas.

Choose the 8, 10, 12, 14, or 16 inch diameter to match your chimney. Keep the air gap clear of framing, insulation, drywall, and anything else that can burn. Never fill it. The roof opening must be 4 inches wider than the pipe’s outside diameter. Use only unmodified DuraChimney II parts, not DuraTech, DuraPlus, or another brand’s chimney parts. Need a bracket that carries a tall chimney’s weight? See the DuraVent DuraChimney II 8 to 16 inch Supplementary Support. The DuraVent DuraChimney II 8 to 16 inch Wall Strap ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.

DuraChimney planning installationPlanning Your Installation:

The following recommendations are a general guideline to assist in the layout and selection of the chimney components needed for your installation. Always follow Duravent Installation instructions enclosed with the cap or support box before installing your chimney system. Installation instructions can be viewed online at www. duravent.com, under catalogs and instructions.

  • Measure the diameter of the fireplace flue outlet. An improperly sized chimney results in poor draft and excessive creosote formation.
  • Select the chimney with the same size diameter as the fireplace flue outlet. Refer to the chimney sizing chart in the back of this catalog for masonry fireplaces.
  • Install the chimney in an enclosed chase.
  • If possible, avoid offsets. A straight vertical installation is more efficient and less likely to develop creosote. If an offset is required to avoid rafters or other obstructions, measure the horizontal distance required and the vertical height available. Both 15° and 30° elbows are available. Elbows greater than 30° are not allowed in the United States. Two offset (four elbows) in a single installation is permitted. Refer to the offset chart in the back section of this catalog. At least one Elbow Strap is required. Elbow Straps ensure adequate support.
  • Determine the minimum chimney height above the roof line. Building codes require a minimum of 3′ above the roof penetration and at least 2′ higher than any portion of a building within 10′. See figure 1. The termination cap is installed above that point.
  • Chase Top Flashing is available. A pitched roof flashing can be locally made, if required. A storm collar is required for all installations using a flashing.
  • Determine the total length of chimney required for the installation. To calculate the installed per length of 10″-16″ DuraChimney II pipe, subtract 1″ per joint. Minimum recommended chimney height, at sea level of straight vertical chimney, is 10′ to 15′ above the fireplace outlet. Higher elevations, or the use of elbows, will require approximately 30% to 60% more height to provide for an adequate draft.
  • For a UL approved shroud, see the DuraChimney II Shrouds Installation Instructions (L181). View online at www.duravent. com, under catalogs and instructions.
  • Be fire safe. Maintain at least 2″ clearance to combustibles. Follow local building codes and have your chimney inspected by a certified professional.
