The invention relates to a grill system that achieves direct and indirect heat functionality through one or more mechanisms including a heat deflector within the cooking chamber that is adjustable through a repositioning means that allows a user to reposition the heat deflector in relation to the burner from a location external to the cooking chamber when the grilling system is in cooking operation. The system may also provide a drip tray with louvers or other apertures placed over the burner area for further optimizing transfer of direct heat to the cooking area.
