The DuraVent DVL 5" to 6" diameter Increaser is used to increase the flue from 5" to 6" and adds 6.25" to the stove pipe run.
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.
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.
