Is it safe to run the furnace inside my barn ?
Since the OP has asked this question twice, and no one has responded to it. I'll take a stab at it.
Are you worried about carbon monoxide? If so, the only issue would be if there are any animals or people in the barn with it overnight. If there are no animals or people, no concern about carbon monoxide.
If you have fuel tanks or gas for the mower or something like that, the safest thing to do would be to remove them from the pole barn while you run the furnace. That's probably an overabundance of caution, but still...
All the same, these are just my opinions. I am not liable if you follow my advice and something goes wrong.
