The sealing means takes the formof a sliding plate which is positioned adjacent the grill and has apertures which registerwith the apertures of the grill when the smoke barrier is in an open configuration andlands between the apertures which register with the apertures of the grill when thesmoke barrier is in closed configuration. The plate is slidable horizontally relative to thegrill automatically in response to the presence of smoke and/or heat between a firstposition in which the smoke barrier is in its open configuration and a second position inwhich the smoke barrier is in its closed configuration.
