DVL double-wall stove pipe completes the venting system when used with one of DuraVent’s chimney products, such as DuraTech or DuraPlus. DVL’s double-wall, air-insulated design reduces clearances to combustibles from 18” to 6”, the closest clearance to a wall of any connector pipe. DVL improves stove performance by maintaining high flue gas temperatures for a strong, steady draft. Because the inner wall is stainless steel the flue heats up faster, stays hotlonger, minimizes the formation of creosote, and has the same life expectancy as the chimney. Adjustable lengths eliminate the need for cutting or crimping.Required for Manufactured Home installations. See appliance manufacturer's installation instructions.

  • I need to connect to single wall pipe on the stove end and to single wall stainless chimney liner on the chimney end, How do I make those connections?

    A. The Simpson Dura-Vent 8648 would connect to a wall thimble or ceiling support. Then the chimney pipe would connect to the other end of the thimble or support.

  • I need to connect a single wall pipe on the stove to a double wall stainless chimney. How do I make the connection?


    You can't mix single and double wall pipe. If double wall would meet your clearances, then just run the double wall pipe from the stove to the ceiling support. Another option is to use single wall pipe with a UL listed pipe shield on the area where you need the clearance reduction. You can also protect the wall for clearance reduction. Follow NFPA211 and any local codes.
