Your hood should be able to exchange the air in your room ten times per hour. Hence, in a kitchen of 16 square meters and with ceiling height of 2.5 meters, the amount of air to be filtered in an hour is approximately 400 cubic meters. Recommended hood capacity is calculated by multiplying the kitchen volume (multiply the width, length, and height of the room) by a factor of 10. Selected Gorenje+ hoods can exchange up to 800 cubic meters fo air in an hour. For optimum effects, the hood should be of equal width as the cooking hob, placed 65 to 75 centimetres above the cook top (depending on the type of hob – with some, 45 cm is enough). To prevent unwanted loss of pressure, observe the recommendations on the diameter of exhaust duct which should be as smooth as possible, as short as possible, and include as few bends as possible, particularly any sharp ones. During cooking, set the hood operation according to expected amount of steam and odour. After the end of cooking, leave the hood to operate for at least 10 minutes.
