Product review (5 stars): Installing: What you need to know
Installing can be a pain unless you do a few things - 1.) do not use those cheesy fasteners to hook it to the wall.  Cut out the wall and install a 1/2" piece of plywood to the studs to attach the zlkb36 to.  Takes more time, but you don't have to worry about it crashing down. 2.) "Optional" cut the plug off and use  a low profile plug.  YOU can get it at home depot as a short extension cord.  I did this because things were a little tight when I wired in the electrical in the wall. 3.) Installing the stack must begin at the top and you should use masking tape to keep it from telescoping back to the bottom.  Also - the screws they give you are about 1/4" long and are a royal pain to get started... but if you use those longer electrical screws for outlets - you will find the threads are the same and much easier to get started.

Great range hood!  I love it.
