DuraVent DVL Double-Wall Black Stovepipe Decreaser
DuraVent is the premier company in the venting industry. With a broad range of engineered venting products, DuraVent has earned its reputation as the industry leader by offering innovative, safe, and professional products for the HVAC and Hearth markets.
DVL double-wall stovepipe completes the venting system when used with one of DuraVent’s chimney products, such as DuraTech, DuraTech Canada, DuraPlus, or DuraTech Premium.
DVL’s double-wall, the 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 creosote formation, and has the same life expectancy as the chimney. Adjustable lengths eliminate the need for cutting or crimping.
- Diameters 6", 7", and 8"
- 016” stainless steel inner wall.
- 018” galvanized outer, painted black
- 6″ clearance to walls.
- 8” clearance to ceilings, including cathedral ceilings.
- 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 by even 1” can affect the draft and have a serious negative impact on 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.
