Rollable design for easy transport and deployment Embossed surface for doubled emissive surface area 70-90 mm flexible diameter to fit various stove ports 5 year material and workmanship warranty Made in Finland For a roll up stove pipe the Hawu roll chimney is surprisingly easy to use, the embossed surface not only adds to its heating effect but also makes deploying it for use far easier than any similar pipe made from regular smooth sheet metal. The embossed patterns inside the chimney also produce microvortices in the combustion gases, increasing draught and reducing soot adhesion. The spring steel split rings offer a very special advantage over solid steel or wire rings, they flex just enough to fit over stove ports of varying diameter from 70 to 90 mm, with 80 mm being the optimum that the chimney itself is designed for.
