DuraVent stands at the forefront of the venting industry, recognized for its wide range of engineered, high-performance venting products. Trusted by professionals across the HVAC and Hearth markets, DuraVent has earned its reputation through innovation, safety, and superior product design.

The DVL Double-Wall Stovepipe provides the perfect connection to complete a DuraVent chimney system, including DuraTech, DuraTech Canada, DuraPlus, and DuraTech Premium.

Featuring a double-wall, air-insulated construction, DVL reduces clearance to combustibles from 18 inches down to just 6 inches—the closest clearance available for any connector pipe. This design enhances stove performance by maintaining higher flue gas temperatures for a stronger, more consistent draft.

The stainless-steel inner wall allows the flue to heat quickly, stay hot longer, and resist creosote buildup, ensuring long-term reliability that matches the lifespan of the chimney itself. Adjustable lengths simplify installation by eliminating the need for cutting or crimping.

 

Features

  • 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 increase from a smaller appliance flue outlet to a larger diameter chimney or stovepipe.
