Product review (5 stars): Installation Notes
Pros: arrives without any dents at all. Was very well packed in a large box. As per other comments on the "instructions," they are as bad as advertised. Don't panic, if you follow a commonsense approach you can do this OR just hire a installer. :>)

1. You have to know where the hood is going so if you have to, cut out a piece of 30"x30" cardboard and place it over your range nice and level at your preferred height. 28" to 36" is suggested, I went with 32" as my wife is petite.

Run a centerline (15") up the wall off your 30". Top part of the extended hood is 12" so make sure you cut your 6" exhaust fan hole inside that area. Your receptacle or electrical junction box has to be inside this as well, set above the two screws that are used to attach the hood to the wall.

2. About those screws used for attaching the hood to the wall: they suck. I am remodeling so had the advantage of running a couple of horizontal studs behind my sheet rock to hang the hood. I used two screw bolts with 3/8" inch heads so that I could use a ratchet wrench to tighten the hood to the wall. It's very difficult to turn the two screws down inside the range hood because you have to attach the bottom part of the chimney.

3. I used an extender to bring up the height of the exhaust out side of the hood. I used aluminum tape as well as 6" clamps.

Cons: Instructions and the the way the range attaches to the wall.

NOTE: My controls on my model of the hood is touch control, not press down. Took me some time to get this. Just lay your index finger on the icon and it works. It is a little noisy but I think for the price and design this is one of the trade offs that you have to accept. I could have spent $1000 for a really quiet one but not in my budget and it really doesn't bother us.
