Cooking plate and a procedure for mounting a cooking plate

A cooking plate mountable into an opening of a resting surface, said cooking plate comprising:

• a functional component;
• a component box configured to house the functional component and including a base and side walls, at least one of the side walls being connected to a resting fin capable of resting on the resting surface in a mounted state of the cooking plate in the opening;
• and
• a positioning device including a limiter limiting a minimum distance from the at least one of the side walls of the component box to an opening edge in the mounted state of the cooking plate in the opening,
• said limiter being configured to be foldable between a first fixed position in which the limiter is parallel to a surface of the resting surface in the mounted state and a second fixed position in which the limiter is substantially perpendicular to the surface of the resting surface in the mounted state, the limiter configured to adjustably limit the minimum distance from the at least one of the side walls of the component box to the opening edge of the opening.
