6" DVL 29"-46" Double-Wall Telescoping Black Stove Pipe - 6DVL-46TA

The purpose of stove and chimney pipe is to remove harmful byproducts of the combusted, or burned, fuel from inside your home. If the byproducts are not properly ventilated from inside the home, then you can have a dangerous buildup of carbon monoxide.

DuraTech is a double-wall, all-fuel stove and chimney system for use with wood stoves, fireplaces, furnaces, boilers, ranges, water heaters, or other appliances fueled by wood, oil, coal, or gas, and zero-clearance fireplaces that are factory-built.

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. DVL double-wall stovepipe completes the venting system when used with one of DuraVent’s chimney products, such as DuraTech, DuraTech Canada, DuraPlus, or DuraPlus HTC. 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.

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.

All stove and chimney pipe are classified and categorized by the inside diameter. If you aren't sure what size you need, measure the inside of your flue opening across inside to inside. If your measurement is 6" then you will purchase all 6" pipe for your installation.

How it works:

The chimney system allows your stove or fireplace to exhaust flue gases while a draft creates the draw that pulls fresh combustion air into the stove. A well-balanced system provides an even, hot fire when it has good draft. The draft suction keeps smoke from coming into the room. Insulation in the chimney pipe is important because it helps keep the exhaust hot until it is expelled outside. Heat in the chimney makes draft, which pulls in more combustion air. This creates a hotter fire, delivering more heat to the chimney, resulting in more draft. The size of the flue is important for the system to work efficiently. The appliance manufacturers installation instructions will indicate how to size the flue to match the stoves flue collar. Stovepipe connects to the stove. It is the usually black interior pipe that transitions from the stove to the chimney pipe with an adapter. It is not insulated and cannot penetrate ceilings or walls. Chimney pipe is an insulated pipe that is rated to pass through walls and ceilings. In addition to the chimney pipe, supports to hold the system in place, and shields to protect areas from combusting, are needed for the system. The flashing, storm collar and chimney cap are required to seal the system from moisture penetration.

Is double wall stove pipe necessary?

It depends on your clearance to combustibles. Single wall black stove pipe needs to be at least 18" from combustibles, will radiate more heat than double wall black stove pipe (desirable in most cases), costs way less, and can be cut to length if needed. Double wall black stove pipe has a 6" from combustibles. Mobile home installations require double wall black stove pipe for added safety.

How much clearance do you need for double wall stove pipe?

Double wall black stove pipe has a 6" from combustibles. Clearances to combustibles can also be reduced with various items such as Pipe Heat Shields. Mobile home installations require double wall black stove pipe for added safety.
