Measure the distance from the top of the range to the bottom of the hood. We recommend allowing 28-36 inhces between the bottom of the hood and your cooking surface. You will want to make sure that you buy an under cabinet or wall mount range hood that, when fully installed, the bottom of the unit will be at least 28-36 inches above your cooktop. If you take the distance from your cook surface to the bottom of the cabinet and subtract the recommended 36 inches, and again subtracting the recommended 28 inches and you will be left with a distance range that your hood can be.
