INDOOR:
If cooking indoors, we recommend allowing 28-36 inches between the bottom of the hood and your cooking surface. Less than 28 inches from the cooktop will put the heat too close to the electrical components, and more than 36 inches from the cooktop will start to decrease the efficiency of your hood. Adjust your hood anywhere within the 28-36 inches range to bring it to the desired eye level. The average height is 32 inches above the cooking surface.
OUTDOOR:
We suggest you mount your outdoor hood no closer than 36 inches from your cooking surface. Outdoor grilling radiates intense heat, so the distance from the cooking surface should be farther than recommended for indoor cooking to prevent damage to the hood. The average outdoor mounting height is 36-42 inches above the cooking surface.
