We just bought a used Jotul 602N (in great shape) for a very small cabin (150 sq ft). Installation specs do not describe the diameter for a pre-fab double-wall chimney. I have an 8" double-wall chimney and am wondering if it's ok to use? Specs for masonry chimneys are clear: at least 6" and not more than 8".

It was designed for 120mm or 5" but will work on 150mm or 6". The stoves came with a 120 to 150mm increaser. 8" is pushing it.

Yes, 8" would be too large. Forgetting performance even, from a purely aesthetic argument it would dwarf the stove. Attached is a pic of ours in our cabin with 6" double wall and 6" insulated above. 6" even looks big for that stove when using double wall.
