Remember that there is a minimum gap between a freestanding cooker and

Check the cooker instructions.
The one I've got explicity says no gap is required, providing the
worktop is no higher that the surface of the hob. That that's
likely to depend on the arrangement of the burners (burners are
quite raised and not very near the edge of this cooker).
