1. The range hood should be installed directly above the center point of the gas stove, and the distance between its bottom surface and the gas stove should be within the range of 650 mm-750 mm ..

2. Try not to install the range hood near the doors and windows with strong air convection, so as not to affect the range hood effect.

3. The air outlet pipe should not be too long, preferably not more than 2 meters, so as to minimize bending and avoid multiple 90-degree bending, otherwise it will affect the oil smoke absorption effect.
