extend chimney stack

Will extending the stack up to 3 sections on my 2300 e classic wood boiler have any adverse effects on it's performance?  I currently have 2 sections installed.  Thanks for the help.   ???

I don't know all the physics of flu draft and such, but I can tell you that I used 3 sections from the onset with my 2300 last year, and the performance was good.

depending on your site, it could improve the performance.

I started with two and did not feel that there was enough draft and the smoke was just lingering in my yard. After about a month of burning I added anouther pice of chimney and the smoke was able to then leave my yard and the draft was noticibaly increased especially when filling the boiler, the flames and the smoke went up the chimney instead of out the door and in my face. To make a long story short; three pices of chimney works great for me but due to your landscape probably being different than mine, I could not tell you how it will work for you. Good luck

I put a third section on mine thinking that it would help with the smoke rolling out the door when i opened it, but it didnt. I didnt do anything to affect the performance at all. The dealer told me the more sections the better, but i wasnt willing to invest more money in pipe when i didnt really need it.
