My cousin in Philadelphia is looking at a Jotul F3CB for the 600 sq ft addition to his house.  New contruction of course, so he will use a pre-fab chimney to go straight up and out.  Vaulted ceilings, maybe 12'?  Does he need a double-wall insulated chimney, or single-wall?  I did all this research for my insert install in a masonry chimney, but never learned the ins and out of a fresh install of a freestanding stove.
The user manual says "A prefabricated chimney complying with the requirements for type HT (2100°F) chimneys per UL 103 or ULC S629."
I assume 6" inner diameter?
