I've owned 2 Nashua's over the yrs. Very good stove that will really rock the heat. I had mine plumbed into a 6" chimney and still had to put a damper on it.If your chimney is tall and drafts well it won't be a problem at all. From stove to cap for me is 41'.
as far as my experience goes it will draw quicker taking it from an 8 to a six. ive done similar my self and was surprised what a difference it made. all the 8 inch flue collars on stoves get reduced to a six liner anyway a meter up the chimney , mostly i think to save money no regs here sayin it cant be done ,
To tell you the truth I didn't know that you could 45s in stove pipe, and I haven't bought the stove yet still weighing all my options. I dont want to buy a new stove because I just don't have that much to work with. I was hopeing I could use 6 inch pipe to save a few bucks if it could be done safely and still work properly. I'm want to do this to help with the heat bills next winter, having total eletric with an average bill of 350 to 400 a month in the winter really stinks.Given those parameters I say don't do it. There are too many things going against a successful install: basement install (possible negative pressure), choked down stove, 3 90s in the smoke path, average height chimney. Consider selling the Nashua and getting an affordable modern big stove like the Englander 30NC with a 6" flue or go 8" all the way and eliminate one 90 turn by connecting with a pair of 45s and a diagonal connector.
A new stove if you catch it while pricing is good in the next few weeks will not be that much more than a used stove. The savings after that will more than pay for the difference.

Hi everyone, my name is Joe. About 5 months ago, I started working at The Chimney Sweep in Bellingham, Washington. I finished my apprenticeship on the truck and have moved into an office role. I've been browsing the forum for a little while now, but haven't posted yet, so here goes my inaugural post:
It seems like a couple more questions have popped up since the thread started, but I wanted to address the original question about 8" flue collar and 6" chimney. I do not know anything about the OP's particular woodstove (Nashua brand stoves seem to have a relatively small digital footprint), but here is some information on flue undersizing:

Always go with what the manufacturer certified the unit with, and when in doubt, check the owner's manual. I hope this helps.
