No more struggling with insulation wrap; our pre-insulated design means faster, easier installation, saving you time and labor. Crafted from robust 316L stainless steel, the FireFlex liner offers exceptional corrosion resistance and can withstand extreme temperatures, ensuring a lifetime of reliable service.

Fireside Chimney Supply's FireFlex Pre-Insulated Chimney Liner Kits are made of a 316L .006 Stainless Steel Interior Liner, a 1/2" layer of chimney liner insulation, an aluminum outer liner to help make for an easier installation and is used for all fuels. The outer aluminum liner is used to protect the insulation during shipping. We recommend using Heavy Wall Liners for both coal and corn usage.

Our Pre-Insulated Chimney Liner Kit is also available with a 316L Stainless Steel outer liner. Please Call For Price And Details.

Our FireFlex 316L stainless steel stainless steel flex chimney liner system is designed to reline existing chimneys or to be used in new construction. The flex chimney liners are manufactured using the highest grade mill certified alloys. They are manufactured with a continuous strip of stainless steel, interlocked and diagonally crimped to produce a gas and water tight system of superior strength. With 7 ply seams and 10 corrugations between each seam, the flex chimney liner will deliver the flexibility needed to get the job done.

Key Features:

  • Pre-Insulated Design: Saves significant installation time and effort by eliminating the need for separate insulation wrapping.
  • Premium 316L Stainless Steel Construction: Ensures maximum durability, exceptional corrosion resistance, and prolonged lifespan, even in high-temperature environments.
  • Complete Tee Kit: Provides all necessary components, including a top plate, rain cap, and flex liner, for a seamless and secure installation.
  • UL 1777 Listed and Lifetime Warranty: Guarantees industry-leading safety standards and provides long-term peace of mind.
  • Reduces Creosote & Condensation: Maintains higher flue gas temperatures, minimizing dangerous creosote accumulation and harmful moisture damage within your chimney.
  • Versatile Appliance Compatibility: Perfectly suited for wood stoves, oil, gas, and pellet burning appliances, offering a flexible venting solution.

Specifications:

  • Top plate or Flue fit top plate (optional) for the chimneys with the clay tile liner, both with EZ connect collars
  • Rain Cap with screen to eliminate the pests
  • Appliance connector with EZ connect for the insert or vertical hook-up
  • Lifetime transferable chimney liner warranty except when using coal or corn for fuel
  • Complete installation instructions
  • UL1777 Listed in the USA Underwriter Laboratories

PRE-INSULATED LINERS ADD AN ADDITIONAL 1 1/2" TO THE OUTER

DIAMETER OF THE LINER

When Attaching An Appliance Adapter, 2-Part Flex Tee or When Using a Pulling Cone, Please Remove Approx: 4" of Outer Liner and Insulation to Make Your Connection.

We strongly recommend using a polypropylene chimney brush versus any metal chimney brush. Polypropylene is non-abrasive and does not scrape the interior of the chimney liner. Metal brushes have an adverse effect on the liner.
