the hood is supplied with the hood skewed because the brackets were twisted. At the request of the seller, I have recovered! Everything is almost back to normal. I installed without recycling ducts. This design is well installed. the power cable was incorrectly positioned within the hood and prevent the attachment of one of the carbon filters. I made the change by myself. Beware, if you do not want the power cable, then you must install a socket just above the hood or in the decorative fireplace because the cable exits from the hood into the base of the fireplace. The hood must be turned on to be able to operate the light (19/07 correction: my mistake, the light is independent). buttons to increase / decrease the flow are not in logical order (up arrow to reduce the flow and down to increase the flow!) big doubt on the effectiveness of the hood to capture the fumes with carbon filters installed. They create a very large drop and visually much vapor is then not picked up (she is almost 100% without filters).
