Hi all. I'm new to this site and hope to gain some valuable knowledge here. I just picked up an old Jotul 602 B and new Simpson DuraVent Duratech 6" insulated chimney pipe. The 602 B is stamped 1980 and has a dark green enamel finish. I have an unusual installation...we live in a yurt (see www.coloradoyurt.com for info if you're unfamiliar with yurts). I'm installing the stove and chimney myslef and have a few questions. 1. Because the yurt wall is different than a nomal stick-built wall, I'm not planning to use a wall thimble (the yurt company provides a steel pipe outlet). Therefore, it would be difficult to transition from interior black stove pipe to exterior chimney pipe. So, I'm planning to use chimney pipe for the entire installation (interior and exterior). Does this pose any problems? Is it alright to attach the insulated Duratech pipe to the stove outlet? Or should I plan on transitioning from stove pipe to chimney somehow (I've seen it done on other yurts and know it's possible with the right parts)? 2. We have wood floors. What materials are acceptable for the hearth? Hearth dimensions? Thickness? 3. We live in spruce/fir/aspen at 8300' in Colorado. Which of these species are preferred for burning in the Jotul? We also have access to gambel oak, pinon, and juniper, which I'm thinking might burn better/longer...thoughts? 4. Any tips on firing the 602 B? 5. The 602 has some surface rust on the dark green enamel and on the cook plate...best ways to clean/remove rust? Any advice would be appreciated. We can't wait to try out the stove! Thanks!
