Reducing and 8" vented stove to a 6" chimney

Yes but we hear of it being done. Usually causes problems though and there is a reason the manufacturer built it for 8"

You may also have problems with your insurance company... if they inspect, or require any sort of inspection. If they don't require inspection, and you were ever to lose the house to a fire due to the stove or chimney, they would likely deny the claim based on improper installation (going against manufacturer's instructions).

Do not reduce to 6" flue unless it is approved by the manufacturer… On the plus side, the smaller the flue will create a better draft…

I am building a new house and with the attic insulation and roofing I installed a 6" class A chimney 3' above the roof line, 6' total class A. With another 14' or so that will be single wall pipe, inside, no elbows.

I am now ready to buy a stove, I know of a Dutchwest 2462 extra large stove, but it has an 8" vent. Is it a bad idea to buy it and adapt it down to 6"?

Is this the cat or non-cat version? The non-cat can use a 6" pipe/liner.

You'll get the easy (and probably most correct answer) to simply stick with mfg recommendations. However if you could talk to the stove mfg they probably had a specific chimney height in mind or in test when they made the stove. I have a total of 41' from stove to chimney top with 35' of that being Class A. Guarantee I can draft any 8" stove on that 6" pipe and have. So based on your description I might hesitate with putting that stove under that pipe. Especially since most of your pipe is single wall stove pipe that won't draft as well as the double wall chimney pipe.
