DuraVent | DVL Double-Wall Black Stovepipe Increaser

The DuraVent DVL Double-Wall Black Stovepipe Increaser is the trusted solution for connecting smaller stovepipes to larger chimney components, ensuring a seamless transition that enhances draft performance and system efficiency. With DuraVent’s legacy of innovative venting solutions, this increaser embodies the quality and safety that homeowners and professionals rely on.

Crafted with durable double-wall construction, the DVL Stovepipe Increaser reduces creosote buildup and minimizes clearance to combustibles, making it a safe and space-saving choice for any installation. Its sleek black finish adds a modern, professional aesthetic to your hearth setup, perfectly blending function with style.

Whether you’re upgrading or completing a new installation, the DuraVent DVL Double-Wall Black Stovepipe Increaser delivers reliability, efficiency, and peace of mind. Trust the experts at DuraVent to provide the venting solutions you need for a safer, more efficient home heating system.

The DuraVent DVL Double-Wall Black Stovepipe Increaser is designed to be the perfect companion to your DuraVent chimney products, including DuraTech, DuraTech Canada, DuraPlus, or DuraTech Premium. Its double-wall, air-insulated design is engineered to reduce clearances to combustibles from a standard 18 inches to a mere 6 inches, making it the closest clearance to a wall available for any connector pipe. This not only improves safety but also provides you with greater flexibility in your stove's placement.

DVL isn't just about safety; it's about performance too. By maintaining high flue gas temperatures, it ensures a strong and steady draft. Thanks to its stainless steel inner wall, the flue heats up quickly, retains heat longer, minimizes creosote buildup, and boasts an impressive lifespan matching that of your chimney. Plus, adjustable lengths eliminate the hassle of cutting or crimping, simplifying installation.

Benefits:

  • Enhanced safety with reduced clearances to combustibles.
  • Improved stove performance for efficient heating.
  • Minimized creosote formation for easier maintenance.
  • Long-lasting stainless steel construction.
  • Simplified installation with adjustable lengths.
