Finally got a little bit more work done on the exhaust. Plenum made (I'll beef it up later with more duct tape and will make a more permanent kind of weather protection, as well as put a piece of hardware cloth over the opening to prevent critters from entering and causing trouble). Ducting in place. Just need to build the hood, and need a bit of advice on it.
Is there a certain minimum angle the pieces that go from back and sides up to the duct should have? In other words, can the top of the hood be too flat--would that make it not funnel the fumes as desired?
Any other relevant thoughts, numbers, etc. on the matter appreciated.
Thanks!
Judy
