FireFlex 316L Smooth Wall Basic Chimney Liner Kit

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

Our FireFlex 316L stainless steel smooth flue liners for chimneys are designed to reline existing chimneys or be used in new construction. These fireplace liner kits 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, these smooth flue liners for chimneys will deliver the flexibility needed to get the job done.

Sometimes when using the option of ovalizing the smooth flue liners for chimneys, they may have a puckered appearance. This will in no way affect the performance of the liner.

All Fireplace Liner Kit 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 Fireplace 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.

PLEASE NOTE: When installing Smooth Wall Liner, Install With Arrow Pointing UP.

Please use the following formula to get the approximate weight.      .16 X Diameter X Length = Weight

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.
