DuraVent PelletVent Pro Chimney Pipe - 4 Inch Inner Diameter Stainless Steel Double Wall, 36 Inch

If you're installing or updating a pellet stove venting system, this DuraVent PelletVent Pro pipe is exactly what you need for safe, efficient operation. This 4-inch inner diameter, 36-inch long straight pipe features double-wall construction with a stainless steel inner wall and galvalume outer wall that's built to last. The Type L biofuel chimney pipe is UL listed and approved for just 1-inch clearance to combustibles, which makes installation so much easier in tight spaces. The fully unitized twist-lock construction (they call it the Duralock system) creates tight seals that prevent exhaust leaks and maintain proper draft. What's really convenient is that you can use this pipe in both vertical and horizontal installations, giving you flexibility in your venting layout. The laser-welded seams ensure durability, with a .012-inch stainless steel inner wall and .018-inch galvalume outer wall that resists corrosion. When calculating your installed length, remember to subtract 1.5 inches from each pipe length for the connections. The PelletVent Pro system is specifically designed for stoves and inserts that burn wood pellets, oil, corn, and other biofuel products. I've worked with various venting systems, and the quality of DuraVent products is consistently impressive - the materials feel substantial, the connections engage smoothly but securely, and the finished installation looks professional. The stainless steel inner wall handles high temperatures and corrosive combustion byproducts without deteriorating. Whether you're doing a new installation or replacing old venting, this pipe makes the process straightforward and gives you peace of mind knowing you're using properly tested and certified components. The 36-inch length is perfect for main runs, and the double-wall design maintains flue gas temperature for better draft while keeping the exterior cool enough for reduced clearance requirements. Seriously, don't cut corners on pellet stove venting - this professional-grade pipe is worth every penny for safety and performance.
