DuraVent DuraLiner Flat Stove Connector: a straight connection above your fireplace insert

The DuraVent DuraLiner Flat Stove Connector is a single wall fitting that joins a fireplace insert to the liner inside the chimney. It sits on the insert’s flue outlet, the opening where exhaust leaves, when that outlet points straight up the chimney. The round version joins a round outlet to round liner pipe. The oval version takes a round outlet into an oval liner. The connector attaches to the insert with high temperature sealant and screws. DuraLiner is DuraVent’s factory insulated double wall pipe for relining a masonry chimney that vents a wood, pellet, coal, oil, or gas appliance. Relining means putting a new vent pipe inside the old chimney.

Choose round or oval on this page, then select a 6 inch or 8 inch size to match your connection. Oval liner can fit a chimney passage or damper opening too narrow for round pipe while carrying the same flow as the corresponding round size. The chimney’s inside shape determines which liner shape to use. Need an angled connection instead? See the DuraVent DuraLiner 30 Degree Stove Connector. The DuraVent DuraLiner Flat Stove Connector ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.

Planning Your Installation:

  1. Refer to the Typical Installations for the needed parts for installation.
  2. The size of the liner should match the outlet size on the appliance.
  3. Determine use of round or oval pipe based onthe interior shape of the chimney.
  4. Determine the length of liner needed. Subtract 1 1/2″ overlap per joint on pipe. When using Extend-A-Cap kit, liner must extend 6″ above top of the masonry surface.
  5. Make sure the top of the masonry chimney has a leveled surface to insure a proper fit for the Extend-A-Cap or Transition Anchor Plate and to provide a secure, leak-proof installation.
  6. If a free-standing appliance is used, select the vent or stovepipe pieces to connect from the appliance to the liner. Refer to installation instructions.
  7. For Installations using a Transition Anchor Plate, refer to the DuraTech, DuraPlus, or DuraPlus HTC catalog section or installation instructions for proper parts and installation.
  8. Important! Check to be sure the installation complies with all local and national code requirements, including clearance to combustibles. Contact the local building inspector for permit requirements.

 

Design Recommendations

  • The following design recommendations are a general guideline to assist in the design and selection of liner components for your installation. Always follow DuraVent installation instructions enclosed with the cap or support box before installing your chimney system.
  • Before relining a chimney, it should be cleaned and inspected, by a certified chimney sweep, to verify the integrity of the mortar and masonry.
  • DuraLiner is approved for 0″ clearance between the liner and masonry and 0″ clearance between the masonry and combustibles.
  • DuraLiner is used for wood-burning appliances when zeroclearance or oval pipe is needed.
  • Refer to the appliance manufacturer for installation requirements affecting venting. Keep the vent path as straight as possible for best performance.

 

Restore Deteriorating Chimneys with DuraLiner
When a masonry chimney is damaged or has fallen down, it can be replaced with a safe, listed liner system or factory-built chimney. DuraLiner, when used with a Transition Anchor Plate and in combination with DuraTech, DuraPlus, or DuraPlus HTC Chimneys, replaces the damaged masonry chimney with a safe, efficient, and economical listed chimney system (DuraPlus HTC is listed for use in Canada). See Typical Installations for details.
