10" Stainless Stack

[DocsMapleSyrup]

I'm looking for 4-6 foot pieces of SS stack with 10" diameter. Jim at Smoky Lake Maple only has 2' and I live in NE Minnesota. Any ideas? DuraVent doesn't have 10" in stainless from what I can tell. Where is everyone else getting their large diameter stack and steam hood chimneys from?

Most get stack and steam sections from a maple supply- they carry the sizes that are much bigger than the usual stove pipe sizes. Do you have a sheet metal shop near you? They can make something up for you and it will probably be cheaper than the maple supply companies. I had a local place make all my steam stack.

I run 8" duravent stainless, Works good and looks good, plus they are 4ft sections.

CDL will make size you want in 4' sections

Thank you for the info.

I'm not sure what your concern is with 2' sections? That is what I have and it works just fine. It was also easy to handle on the roof by myself. I guess the only downside I can think of is having a seam where you go through the roof. But with single wall pipe fire your not really looking at the same Fire Codes as you would with a residential installation.

here's a place that has 10 inch stainless insulated pipe,don't know if you'll like the price for 3 fter
they also have single wall but only in 24 inch sections

Let me ask a different question. I was advised that on my 2x8 arch, I should use 10" stack pipe. I have a total of 72 square inches of outlet (4"x18") at the stack plate exiting my arch. 8" pipe has area of 50.27"; whereas the 10" stack has an area of 78.54". I have to go up 22' to get out of the roof of the sugar shack. What is your opinion on using 8" vs 10" stack for draft. Can I get by with 8" stack for an AOF/AUF arch?

If you are inducing air into the arch, draft is no longer part of the conversation. And yes, a 2x? Arch will work just fine with an 8in stack pipe.

Thanks Mellondome. That will save me some $$$ and make it easier to source.
