PRODUCT INFORMATION
Model Saf-T Liner system is intended for use in conjunction with any residential building, heating appliance burning gas, liquid
or solid fuels, such as a woodstove, fireplace insert, or an oil or gas fired central heating furnace, vented through masonry
chimneys only. These heating appliances may not exceed the maximum continuous flue-gas outlet temperatures of 1000°F
or cause condensation of corrosive acids on the liner, or create positive pressures in the chimney system. Saf-T Liner is not
intended for Category II, III or IV burning appliances. See Table 1 for Technical Specifications.
Saf-T Liner is listed to UL 1777 and is a high quality stainless steel lining system designed for relining existing masonry
chimneys. It satisfies code requirements as a substitute for 5/8” fireclay liners and has undergone extensive testing to make
it the leader in the stainless steel chimney lining industry. The installation of Saf-T Liner should be performed by an experienced
professional who works with chimney and woodstove related products on a regular basis.
Saf-T Liner is intended for use in accordance with the following National Fire Protection Association Standards, 211, 54 and 31.
GENERAL INFORMATION
Ensure your installation will conform with all federal and municipal building code requirements. Before commencing your
installation, contact your local building or fire officials about restrictions and installation in your area. Obtain any necessary
building permits. If you choose to have your liner professionally installed, have it installed by professionals who are certified by
N.F.I. or CSIA.
Authorities require that the masonry chimney extend not less than 3 feet above the highest point where it passes through the
roof of a building and not less than 2 feet above any portion of the building within ten feet (see Fig. 1).

appliances to chimney flues serving a solid fuel burning appliance.
