The DuraVent DVL 6" diameter by 29"-46" telescoping length of double wall black stove pipe adds between 27.5" and 47.5" of length to the stove pipe run. DVL double wall stove pipe can not be cut to length so the telescoping length makes installation simple.
For example, if you're installing a wood burning stove and plan to go through the wall with the chimney, you might need a telescoping length on the vertical run to ensure you can line up the height of the 90 degree elbow perfectly with the opening on the wall thimble. Similarly, you might need a second telescoping length to ensure you can get the proper length from the elbow to the wall thimble.
DVL has a .016" stainless steel inner wall and .018" galvanized outer wall that is painted black.
If plan to exit through the ceiling, you will likely need a telescoping length to ensure you can connect to the ceiling support box with ease.
DuraVent DVL will connect directly to the AllFuel HST Stove Pipe Adapter for a seamless transition to AllFuel HST Class-A chimney pipe and components.
Note: DuraVent DVL double wall black stove pipe is intended for interior use only. This means that it is meant to connect your appliance to your Class-A chimney system. It should not be installed through combustible materials like walls or ceilings or be exposed to outside weather conditions.
