Hi everyone, my RF build is progressing now, and I’ll soon be at the stage of fitting the stack.
I just want to make sure I get it right.
It’s a relatively small build, tank size 46” X 15”, FB 15”X15”.
With it being so long and skinny it seems the right thing to do is to go big on the stack for good air flow, I was planning on 6” X 36”.
I’d like to hear people’s opinions.
Thanks, David.

I used this tutorial/calculator for my build (in signature below)... Run your numbes through it and it will give you the size you need...

If I’ve used the calculator correctly, then a 6” stack only needs to be 6.5” long 🧐
Is there any harm in going longer than what’s calculated?
 
I think he mentioned somewhere in there that it should be somewheres around 32" above the cook chamber for the best draw...
Yes, I think you’re right. If I make it 32” long it will be 5X the ESV required.
Is there any problems with having the extra length?
