DVL: Telescoping Length
DVL's Double wall air insulated design reduces clearances to combustibles from 18" to 6", the closet 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.
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 required.
Double Wall interior stovepipe for connecting wood stoves to manufactured chimney.
6" clearances to walls
