Replacing Ceran Glass Cooktop

I need to replace a black ceran cooktop for a neighbor. What are the procedures for replacing? What screws, etc to be removed or whatever holds the top down.

This is a sears drop in electric range model number: 790.46599501, S/N NF61020856

Hi Roy,

I believe the instructions attached to this post will help.
