what is the distance required between the stove top and the microwave/fan vent
By a long distance, using a microwave is more conservative on electricity than by using resistive heating that a stove utilizes.
I've read on GE installation manuals (at GE.com) that the space should be a minimum of 30 inches from the cooktop surface to the bottom of the cabinet touching the top of the microwave.
18" is standard (same as the distance between the counter and upper cabinets), and most modern cabinets that microwaves are suspended from are built for this.

I believe you are asking about under-cabinet microwave ovens. There is no electrical code rules for spacing between the stove top and the bottom of an under-cabinet microwave oven other than to "follow the manufacturer's instructions". The manufacturers of both appliances probably have substantial requirements in their instructions relating to the spacing.
To safely install a microwave above a stove, follow these steps: Ensure there is enough space between the stove and the bottom of the microwave. Use a mounting bracket to secure the microwave to the wall. Make sure the electrical outlet is properly installed and accessible. Follow the manufacturer's instructions for installation carefully. Consider hiring a professional if you are unsure about the installation process.
To install a microwave over the stove, you will need to first ensure that there is a proper space for the microwave above the stove. Then, follow the manufacturer's instructions for mounting the microwave securely to the wall or cabinet above the stove. Make sure to also connect the microwave to a power source and vent it properly to ensure safe and efficient operation.
