Clearance above range for microwave

[Jon mackay]

Is there a minimum clearance requirement for above a glass cooktop range?

Had an over the range microwave / vent combo unit with only 14" from cooking surface to the bottom of the unit.

Also while on the subject, does anyone know what clearance from a cooking surface to the bottom of the cabinets is required?

This might help. www.inspectionnews.net/home_inspection/h-e-l-p/15401-cook-top-too-close-cabinet-vent.html (http://www.inspectionnews.net/home_inspection/h-e-l-p/15401-cook-top-too-close-cabinet-vent.html)

13 1/4 inches above the Range Top is as low I have seen for a Manufactures Microwave Installation Instruction.
