Ordered the fan yesterday and will pick up duct in next day or two.

garbageman, I'm pleased with how the hood came out but I did neglect to put any sort of sealant or adhesive between the FRP and edge of plywood endcap where I screwed it down. Not a big deal but that's the only thing I might do different if I were to do over.
I wouldn't do flex duct. Whatever duct you use will result in some condensation. If you angle a rigid duct it will all roll downhill and you can plan for it to escape. A flexible duct will trap water in all of the corrugation and well that could get funky overtime.

Just make sure you have a powerful enough fan to handle the ductwork and you should be fine. At least that is how I would address it.

I appreciate the advice on the flex-duct, ToV. I'll be sure to use rigid duct.

The fan came in yesterday. I'm going to make slight changes to the hood tomorrow to accommodate the fan.

I intend to replace the side 2x4's with longer ones that will allow me to mount the fan directly to the hood. I should have thought of this earlier...

The overall expense would only be a few dollars more if I had initially taken this approach. I'll be sure to post pictures tomorrow.

Ok, I went to hang the hood by myself and it went from about 60 lbs to around 800 lbs.

It's currently just hanging with rope. I'll level it and secure it with 1/8" cable over the weekend. Should also have all the duct run by end of the weekend.

Sexy! Might be cool to get some waterproof LEDs to mount inside the hood...

Never thought I'd hear an hood be called sexy.

Great project. The ingenuity of homebrewers never cease to amaze.

Looking forward to the next installment!

edit, LEDs would look pretty cool in the steam.

I have all the duct work done and the fan controller installed! There seems to be plenty of airflow at the end of my 30' of duct.

I need to put in the hood drain line and route it to the sink, but otherwise this project is done.

On to the kettles and control panel!

Not sure what the proper name is, but there is a type of condensate trap you may want to consider. Sort of like a p-trap on a sink....the duct right off the hood goes down, then sharply back up and you can place a drain in the bottom of the "U" where the water will collect. Should keep a LOT of the water out.

Really like your design!
Did you purchase the pebbled FRP or smooth, seems like HD and the other stores only carry pebbled.

Please let me know how it works out...and thanks for the drawings.
