DuraVent DVL – DVL Decreaserr
Use to decrease the appliance outlet only when approved by the appliance manufacturer or authority having jurisdiction. *IMPORTANT: The diameter of the stovepipe (connector) and chimney should match the outlet size on the appliance. Decreasing chimney diameter even 1” can affect draft and have serious negative impact of chimney performance. Please check the stove manufacturer’s venting instructions closely prior to installing a DECREASER. Be careful to use these components only when appropriate.
Overview DuraVent DVL
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.
