A tube sold by the foot, and the listing that makes it safe · review
A 6 inch by 15 ft liner kit in thin 0.006 inch 316 stainless, with a rain cap and top plate, and no UL number on the listing.
FireSafe gives 316 stainless, a .006 inch liner, a 13 by 13 inch top plate with rain cap and an appliance connector, made in the USA.
The bullets say it meets modern building codes without naming one. Ask for the certificate.
A flexible liner goes inside a sound masonry chimney. Have a CSIA-certified sweep inspect the flue first, match the liner to your stove outlet, and ask whether your chimney needs insulation under the liner’s listing.
