A:Answer Hello- We appreciate you checking with us. All current OTR (over-the-range microwaves), including convection, Advantium ovens, vent hoods, and telescopic downdraft vents can be installed over gas ranges and cooktops* with combined surface burner BTU rating of approximately 65,000 BTUs or less. As long as the 66" minimum clearance from the floor to the top of the microwave is followed there will be no performance or warranty problem. ~For Pro Ranges and Rangetops, we recommend checking the installation instructions for the appliance. If you have any questions in the future, please let us know. We are always happy to help! Joyce@GEA
