I assume (hope) you have a pretty big hole for the exhaust. That box will build a lot of heat, be sure you don’t set the whole thing on fire.

Of course. There is a nice large ported opening at the back to handle the exhaust. Ran it outside the other night for about 5 1/2 hours. Worked great!
I don’t have the cold weather package. Do you; can it be run in the summer that way?
I wouldn’t run it in the summer this way. As DB said, it generates a lot of heat. Really intended for winter use only.
