Guidelines for a perfect installation for a kitchen hood

When buying a hood for your kitchen, it is very important to know not only its characteristics but also the steps to follow for a good choice and correct installation.


It is necessary to know the measures that your glass ceramic has to achieve maximum performance.

1. Dimensions

Choosing a suitable hood size in relation to the cooking zone is essential for a satisfactory result.
Dimensions cooking zone vs range hood

  • If the extractor hood is larger than the cooking zone then the dimension is optimal.
  • If the kitchen hood is the same as the cooking zone then the dimension is adequate.
  • Y If the hood is smaller than the cooking zone then the dimension is inadequate.

2. Situation regarding the cooking zone

As with the size, the height of the hood is very important in order to achieve its maximum performance.

  • Wall hoods must be placed at a maximum height of 70 cm and a minimum of 60 cm from the cooking area.
  • Inclined wall extraction hoods (like Odyssey) must be placed at a maximum height of 70 cm and a minimum of 60 cm, counting from the center of the suction area
  • Built-in kitchen hoods must be placed at a maximum height of 70 cm.
  • The island hoods must be placed at a maximum height of 70 cm and a minimum of 60 cm.
  • And finally the ceiling hoods must be placed at a height of between 140 and 160 cm.

* The inclined wall hoods and integrated hoods, when installed closer to the cooking zone, generate more steam condensation, so it is advisable to dry them after cooking.
** According to the UNE-60335-2-31 standard, the minimum distance of the gas hobs from the extractor hood and / or the furniture must be at least 65 cm.

3. Ventilation

It is a basic requirement that the kitchen is provided with an air inlet to ensure good air circulation and therefore a correct operation of the hood since without this inlet and with the kitchen closed a depression is created that reduces the suction efficiency of the hood.

If there is an air inlet for the gas installation, this would be useful and if not, one must be created.

4. Installation of conductive tubes

Most of the efficiency of the aspiration and noise reduction depends on the path and length of the exit to the outside, for this reason we indicate a series of recommendations so that your satisfaction is greatest.
