THank you all for the help (except for the "find a new hobby" comment, which guess what? Isn't helpful by any stretch. . . if everyone who was learning something new wasn't allowed to ask questions, the world would be a pretty stagnant place). I appreciate the guidance and believe I have all I need. Thanks all.

Fair point! And noted. I'll keep making calls. Still haven't been able to find the right pipe anyway

Sure, but there really isn't a code for "forges in a detached workshop" . I'm asking from a functional standpoint....

So here's a question...do I HAVE to have insulated/double walled etc. in the attic and roof portion of the garage? Would it still work well if I didn't ? Obviously still using a shield to keep attic insulation and drywall away from the pipe.

I'm not seeing anything with those results. Yeah some pages come up, but if you browse through them...it's all 8" at best. Aye, this is where I'm at a loss. I really don't know how hot the air is that comes off the fire. My hood is four feet tall by three feet wide and is a side draft. So really, the "chimney" is four feet up the hood before it starts.

I was wondering this...I really don't know what kind of heat is thrown through the chimney on these forges. Can spiral duct handle the heat?

Good morning everyone, Long time lurker, first time poster! I'm in a real jam and am hoping someone can point me in the right direction please. Very soon (this week if all goes according to plan!) I will have my coal/coke side draft forge delivered. The hood has a 10" hole for the chimney. The big catch here, I cannot find 10" chimney/stove pipe in Canada to save my life! I've checked the big box stores, I've checked the specialty fireplace/wood stove stores, I've called a few HVAC companies. 6" and 8", no problem! I can find those all day long. 10" ? Non-existent! AND 99% of the American websites won't ship to Canada. I'm located in Ontario, though of course I'm happy to pay shipping if it finds me what I need. The setup will be something like this: Approx. 4ft of pipe needed in the shop, then it passes through a drywall ceiling to approx 6ft of attic, then passes through a metal shop roof and will need to stick 3ft out the top. Trying to do a perfectly straight shot up without any bends. If any of you good folks have any ideas on my chimney, the help would be appreciated! I'm losing my mind trying to find 10" pipe! Thanks all!
