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.
I just mounted a GE microwave with a vent and it told me to mount at a minimum of 21 above the stove top. Comment from contributor P: I am just into this very problem with a client. The above stove cabinet was ordered for a standard vent hood over an electric stove. They then decided on a gas range. That didn't cause a problem. However, they then decided on a microwave unit above a gas range, and the microwave manufacturer, Panasonic, stated that the unit could be within a minimum of 13 5/8 from the countertop for an electric stove, and 16 for a gas range. Ah ha-now we have a problem!
