I turned it on after finally getting everything connected up. Even without the hood it easily grabs virtually all of the smoke from a burning paper towel. I think I'll wait and see whether I need to close off the area and install makeup air. I have a ceiling vent in the wood shop that is easy to open and close. I tested with that closed, and with it opened. Not a lot of difference, but it seemed to help some, so I'll test again when the hood is built, and see what happens. I didn't feel an uncomfortable breeze, and the fact that it was better with that vent opened may mean at least some of the air it's pulling out is not fully heated. So maybe it will work without more layers of complexity.
Any thoughts on my question just above, about the shape of the hood, will be welcomed. Thank you.
