A tube sold by the foot, and the listing that makes it safe · review
A tee kit for stoves that enter the chimney from the side, in 316L stainless, with 98 ratings at 4.6 out of 5.
FireSafe gives 316L stainless, a .006 inch liner, a top plate with rain cap and a tee connector for horizontal hookups, made in the USA.
The tee kit suits a stove on a hearth with a thimble behind it.
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.
