DuraVent DVL 6DVL-X7 Increaser 6″ – 7″ Double-Wall Black
DVL 6DVL-X7 Increaser Double-Wall Black from 6″ to 7″. Use to increase from a smaller appliance flue outlet to larger diameter chimney or stovepipe.
Designed for installation with minimum clearance to combustibles (6” to walls, 8” from top of horizontal run to ceiling). Available in 6”, 7”, and 8” diameters. Subtract ¾” for installed length. Constructed with a stainless steel inner wall.
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.
