Viessmann 60/100 12.5m Chimney Flue Kit (For Room Sealed Systems)

The Viessmann 60/100 12.5m Chimney Flue Kit is a high‑quality flue solution designed for room‑sealed Viessmann boiler systems that require extended vertical flue routing. With a generous 12.5‑metre maximum flue length, this kit enables safe discharge of combustion gases through chimneys or extended vertical paths where a standard flue is not suitable. Engineered to maintain optimal boiler performance and full system integrity, it ensures airtight, room‑sealed operation throughout the entire flue run.

Constructed from durable, corrosion‑resistant materials, the kit provides reliable performance even in demanding installations. It is ideal for properties where longer vertical routing is required, such as multi‑storey buildings or boiler locations positioned far from the roof exit point.
