That sounds a difficult proposition, there are so many buiding regulations about stoves and flues these days, bends have to be shallow and it has to go pretty much to the roof of the house - you'd need an double skinned insulated flue that's cool to the touch I think.
It is possible but I'll reckon it'll be very expensive if you can get somebody to take it on.
Have you thought about something like this instead?

If you're dead set give stovesonline a ring on the number on the website and talk it through with them. I found them very helpful - even though I wasn't buying from them <blush>
