If the instructions say it's necessary then that is what you have to do.
If there's nothing in the instructions about the thickness - contact the manufacturer. Or return and buy a gas hob that does not need the heat resistant plate below - as I've never came across a hob that need this. The heat shields is normally incorporated in the hob itself.
