Product review (1 stars): Possible Bad Design
Great looking unit, however:  The design does not work for a 8 foot ceiling.  The chimneys which are 2 solid pieces 20" long allow for height adjustment since the inner chimney slides up/down to allow adjustment from the ceiling to the desired height above the stove top.  However, the chimneys must be in place to mount the range hood. With the chimney in place, there is no way to access the mounting bolts either at the ceiling or at the point where hte brackets mount to the hood.  I had to cut 9" off the chimneys and 4" off the ceiling bracket to give us the clearance to mount the range hood, and then we had to hold it all up while bolting the ceiling bracket to the ceiling -- it was not an easy mount, and since I did cut the chimneys, there is no option to adjust the height over the stove.  I did notify Akdy of the potential design flaw, and they are looking into it.

Next problem, while operating the fan and the lights (while cooking), all of a sudden, the lights and the fan will go off,  This is now happening all the time. Akdy has sent me a new circuit board and gas sensor to resolve the problem.  The parts just arrived, but I've not yet had a chance to install them.  Hoping they will work.  Through all of this, Akdy has been very responsive.  One positive, the 4 GU-10, 35-watt halogen lights are bright, but hey are hot, so I'm looking to replace them with LED GU-10 bulbs (40-watt equivalent).
