Use for a two-piece installation from stove to ceiling support box or finishing collar. Available in 29�- 46� and 40�- 68� extensions. No cutting is required. Inner Diameter: 6" Adjusts from 29" - 46". No Cutting Required. UL Listed. 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 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. Required for Manufactured Home installations. See appliance manufacturer's installation instructions.
