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".
