Working the Finery Forge

Hi,
I was just wondering if anyone could give me some placement tips. I see that it will let me build it with the bellows passing through objects. I don't intend to do this of course, however, my camp has limited space and I was wondering how much room is necessary around each tip of the bellows for it to be worked. I would hate to place the item as such that I cannot even use it. Normally I would go the trial and error method, however my supply of pig iron is running on the low side! Thanks in advance for any suggestions.
