Product Details:

Applications: Installed in a masonry chimney venting Wood, Pellet, Gas, Oil, and Coal burning appliances. 

Superior flexibility makes the Premium Smooth Wall liner easy to install. When chimney flues make multiple bends and offsets, the heavy duty Premium Smooth Wall liner is able to easily navigate the offsets and is able to be installed down the chimney without damaging the liner. The smooth interior provides less turbulence and improves the draft. UL listed to UL 1777 ensures the liners safety and is also backed with a lifetime transferable warranty. 

  • UL 1777 listed
  • Manufactured from .010 316L stainless steel thickness which offers more durability in tight installations
  • Air and water tight
  • Manufactured with the highest quality, mill certified 316L stainless steel lining
  • Made in the United States
  • Used for fuel applications such as wood, pellet, oil, gas, and coal
  • The smooth interior liner allows 20% more BTU capacity for gas appliances and 15% greater GPH (Gallons Per Hour) firing rate for oil appliances
  • Very easy to clean and extremely durable
  • Uncoils so smooth that it has zero memory or resistance!
