Use to connect from double-wall DVL to DuraTech, DuraPlus, DuraPlus HTC, and DuraLiner for a through-the-wall or ceiling support installation. Required for proper connection. Provides a strong mechanical connection. Painted black. DVL double-wall stovepipe completes the venting system when used with one of DuraVentÂ’s chimney products, such as DuraTech or DuraPlus. DVLÂ’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 hot longer, minimizes the formation of creosote, and has the same life expectancy as the chimney. Adjustable lengths eliminate the need for cutting or crimping.UL ListedADA Compliant: No Collection: DVL Finish: Black Fuel Type: Wood Height: 3-3 4 Inside Diameter: 6 Material: Galvanized Stainless Steel Pipe Shape: Round Style: Functional Vent Construction: Double Wall Width: 9
