Product review (4 stars): Attractive unit, great for a white kitchen.  Features a variable speed fan and two-level lighting.  See installation tips below.
I purchased this unit to replace an older Broan range hood that is ducted vertically to my roof.  I contacted Broan customer service a few times via email with some questions.  They were responsive and very helpful.  This unit comes with installation instructions, but I found a few more helpful tips in customer reviews and other install instructions for similar range hoods.  Here they are: 1) Inspect the range hood carefully when it is delivered to find any dents or weld breaks that might have been made to the hood during shipping.  Mine was in excellent condition, but youll want to contact the seller right away if yours is not.  2) All parts were included in the box (even a round adapter for a round duct) except for one item.  You will need to purchase a wire clamp to install in the knockout for the AC power cable.  These are available at hardware stores and cost less than a dollar.  You could reuse an existing one, but better to install a new one.  3) The metal duct cutout needs to be removed from the range hood.  However, its easy to bend and damage the surrounding sheet metal.  So I used a rotary drill with a metal cutting wheel to cut through the metal tabs holding the cutout in place.  Then it was easy to pull off the cutout with minimal pressure to the surrounding metal.  Wear heavy gloves or be careful not to cut yourself on the sharp edges of the sheet metal.  4)  When the fan is on at high speed, the damper can remain in a vertical open position and not fall back down to a horizontal closed position.  To fix this, extend the plastic tab stop which is behind the damper so it cannot move back enough to get stuck open.  I reinforced the plastic tab with a small nylon wire cable fastened around the mounting tab.  5) The damper must be installed with the hinge facing up and towards the back wall (for a vertical duct).  This correct orientation isn't clearly indicated in the instructions.  6) The light cover can vibrate and create noise when the fan is running.  Just place a couple layers of clear tape over the cover tabs to make a tighter fit.  I bought two clear 40w appliance bulbs since the light cover is frosted and mutes the bright clear light.  And thats it!
