A tube sold by the foot, and the listing that makes it safe · review
The same smooth-wall kit in a 30 foot length for taller chimneys.
The same SmoothWall construction as the SW625, in 30 feet.
A kit that comes up short cannot be stretched, so buy length to spare.
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.

Measure from the top of the chimney to the stove connection and add a little extra.
Check the installation instructions. Cutting too short cannot be undone.

Measure the flue and add a margin. For a small price gap, longer is safer than short.
