FireFlex 316L/Ti Basic Flexible Chimney Liner Kit

Fireside Chimney Supply's FireFlex flexible chimney liner kits are made of 316L/Ti stainless steel and are used for all fuels. However, we recommend using Heavy Wall Liners for both coal and corn usage.

Our FireFlex 316L/Ti stainless steel flexible flue liner system is designed to reline existing chimneys or to be used in new construction.Flexible flue 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 this flexible chimney liner kit will deliver the flexibility needed to get the job done.

All Flexible Flue Liner Measurements are I.D. (Interior Dimension). For O.D. (Outside Dimension) Measurement Add ¼”. Example: A 6” Liner Would Have An I.D. Measurement of 6” and An O.D. Measurement Of 6 ¼”.

Each FireFlex Flexible Chimney Liner Kit includes our very own EZ connect system:

• 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

The Deluxe Top Kits (flat top plate w/ hinged screen lid) are constructed of 22g 304 stainless steel. 

The Deluxe Clay Tile Top Kits (for clay tiles w/ hinged screen lid) are constructed of 22g 304 stainless steel.

Fireside standard thickness liner is .006. Above industry standards. For Maximum flexibility we also offer .005 thickness for the tough to maneuver jobs.

Fireside Chimney Supply offers a complete line of chimney flue liners and hearth products. Feel free to look around and if a question arises - pick up the phone - we're here to help.

We strongly reccomend 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.
