Product review (1 stars): Bad Design ! Vents Are not over the the Main Burners!!!
This expensive and well made hood is a terrible piece of industrial design. Most ranges have their most often used and hottest burners in the front.
So where did XtremeAir place their exhaust vent?-In the rear. So when your hot fumes and stir fry oil rises, they all head to the lights and control panel. My side cabinets and hood are covered in oil. The control panel is very hot and will probably malfunction with all that intense heat from those 10,000 BTU burner below. The unit is only 22 inches deep whereas most ranges are 26- 30 inches.  Why didn't XtremeAir  put the lights  on the side like their wall mounted hoods? Some hoods have their lights in the rear. Their response to me is that my vent does not work well and it is clogged. Do your home work and measure you burners! The vents on this unit are only 15 & 3/4 inches deep! XtremeAir should fire their designer.
The photo shows the vent on their highest F-4 setting.
