Don't want to wait until Dec 1? 35' Stainless Flex Chimney Liner Kit 4" Flue — VOLKA-435 ships in 1–3 business days.
25 ft stainless steel flexible chimney liner kit, 4" diameter (VOLKA-425). Relines an existing masonry chimney so it can safely serve a 4" appliance. Complete kit — liner, top plate, rain cap and connector.
A masonry chimney serving a modern appliance almost always needs a liner. An unlined or oversized flue runs cool, condenses, and builds creosote or corrodes; a correctly sized stainless liner keeps flue gas velocity and temperature where they belong.
Sizing: the liner must match the appliance's flue collar, not the chimney. Measure the full chimney height before choosing 25 ft or 35 ft, and confirm the required diameter in your appliance's installation manual.
