Fireside Chimney Supply's FireFlex chimney lining systems are made of 316L stainless steel and are used for all fuels. Also, 304 stainless steel which is used for solid fuels such as wood, coal or pellets. However, we recommend using Heavy Wall Liners for both coal and corn usage.

Our FireFlex 316L stainless steel and 304 stainless steel chimney liner systems are designed to reline existing chimneys or to be used in new construction. Manufactured using in the highest grade mill certified alloys. 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 it will deliver the flexibility needed to get the job done.

All 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”.

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

Sometimes when using the option of ovalizing the smooth wall  liner it may have a puckered appearance. This will in no way affect the performance of the liner.

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.
