The DuraVent DVL 6" diameter by 18" long double wall black stove pipe is used to add 4.5" of length to the stove pipe run after connection overlap.
DVL double wall air-insulated stove pipe reduces the minimum clearance to combustibles to just 6" to walls and 8" to the ceiling (compared to 18" with single wall stove pipe).
DVL has a .016" stainless steel inner wall and .018" galvanized outer wall that is painted black.
You should also include one appliance adapter to connect the double wall stove pipe to the appliance.
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.
