I found this really cook DIY tutorial on installing a vent hood.
http://www.easy2diy.com/cm/easy/diy_...ge_id=35743526

Here's the Vent Hood that Dale M. Suggested:

And here is some vent hood ducting (and i don't know which kind or how much i need)
http://www.ducting.com/Short_Section_Hoses.html

So as far as I can tell it is simply mounting to a wall, cutting a hole, placing some ducting inside the wall to carry fumes to outside and connecting a outside wall cap.

What type and size of ducting do I need to purchase to go with this? the vent hood says it uses 6" round ducting. aluminum or steel? How long does it need to be? Looks like 1 ft. would be plenty for going straight out thorugh the wall.

Where do i buy the vent cover part for the outside and what size?

JoeDeM said:" I ran the numbers on that hood, and it's not possible to get 900 cfm with a 6" pipe as they claim the friction loss with 1 90deg elbow and say 6 foot run produces a friction loss of 1.07, and produces a 4586 fpm velocity, you would need a 10" pipe to achieve 900cfm"

Since it'll be going straight out through the wall, that shouldn't cause too much drag should it? Also isn't 600CFM the minimum needed?
