I am a licensed CA Contractor and have installed this range, along with numerous others and downdrafts. It will depend on what type of downdraft you have. If your model is a cooktop with an integrated downdraft similar to Jenn-Air this will not be a direct replacement and you will need to add either a range hood or separate downdraft system. This is a slide in range, though I haven't installed this with a downdraft, this unit would work with a separate downdraft system provided that the blower unit for the downdraft wouldn't interfere with the installation of the range.
