Product review (2 stars): Installation instructions are pretty straight forward and clear
Installation instructions are pretty straight forward and clear. The hood mounting bracket doesn't allow the hood to hang parallel with the wall.  It would have to stand out from the wall by about 1/8" to be parallel.  This may not seem to be a problem but read on.  The bottom of the hood rests against the wall.  As a result, the chimney mount, on top of the hood, isn't level and square.  The chimney will not sit flush on the top of the hood. Poorly engineered design.  To correct this, shims must be put in the back of the hood, where it contacts the wall, to keep it square.  Another note, holes on the chimney extensions do not line up well.  Also, hood dB level is stated to be below 50dBs.  I believe it is much louder.  On a positive note, it looks nice.
