DVL double-wall stovepipe completes the venting system when used with one of DuraVents chimney products, such as DuraTech, DuraPlus or DuraPlus HTC. DVLs double-wall, air-insulated design reduces clearances to combustibles from 18 in. to 6 in., 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 manufacturers installation instructions.
