The microwave should be installed with 30 inches between the top of the microwave/hood combination and the top of the cooktop. Please feel free to let me know if you need further assistance. Thank you for using ManageMyLife.com.
Some manufacturers allow smaller clearances. General Electric, for example, requires that its microwaves be mounted with a minimum of 66 inches between the floor and the top of the microwave, which results in a clearance of between 13 and 16 inches from the microwave to the cooktop.he National Kitchen and Bath Association recommends that the bottom of the microwave should be no higher than 54 inches above the floor, which would allow for 18 inches of clearance between the microwave and the typical cooktop height of 36 inches.
