If you can drop the chimney height by 3 ft without compromising code by all means do it. You want to get that draft down to about .09.
It will help, but I can say it will halve it.
So you are currently 5' above the peak? In an earlier post you said that you couldn't remove any because of the height rule, so I got confused.Cool, I have to remove some siding and cut the chase I built but I think I can stay 2' above the peak and keep it in code with a 3' removal. When I built this place (I framed it and installed the chimney) the guy at the stove shop stressed to me I needed to get above that peak for a great draft. Lol

Good. I hope you can do it. It may not quite get you there by itself, but it should help. I'm told that if you change the stack height by a certain percentage, you will change the draft by the same percentage. Generally.I kinda eyeballed by counting the horizontal pieces of siding and think I can get it. I also might be further than 10' from the peak so it's hard to say till I get up there. Plus I was counting the pipe and not the cap before. It's now my understanding that the top of the cap is what is measured.
