Harvia 4.5 inch (115 mm) to 6 inch (150 mm) Chimney Pipe Adapter

Harvia's wood stoves use 115 mm flue connections, while North American chimney runs are commonly 6 inches. This Harvia adapter steps the connection up from 115 mm to 150 mm, so the stove can join a 6-inch chimney. You won't need it if you're using a chimney made for the stove's own outlet size. Check the stove manual and local code for pipe sizing, and have the whole flue run checked before the first fire.
