1. A pelletized fuel delivery and combustion system for converting a charcoal kettle grill to a pelletized fuel grill, the system comprising:
a firebox configured for combustion of a pelletized fuel, wherein, when the pelletized fuel delivery and combustion system for converting a charcoal kettle grill to a pelletized fuel grill is mechanically mated to a kettle of a charcoal kettle grill, the firebox is positioned outside and below the kettle;
a pelletized fuel delivery subsystem in communication with the firebox and operable to deliver pelletized fuel to the firebox at a controlled rate via an auger;
an electric heating element in communication with the firebox, wherein the electric heating element is operable to ignite pelletized fuel in the firebox;
a hopper configured to store pelletized fuel and to gravitationally deliver pelletized fuel to the auger of the pelletized fuel delivery subsystem;
a flue component in communication with the firebox, wherein, when the pelletized fuel delivery and combustion system is mated to a charcoal kettle grill kettle having a plurality of damper holes in its base, the flue component is configured to interface with at least one of the plurality of damper holes; and
an adjustable foot component configured to adjust a height of the pelletized fuel delivery and combustion system relative to a ground level surface; and
wherein the pelletized fuel delivery and combustion system is configured to releasably mate to the exterior of the charcoal kettle grill kettle and to interface with the ground level surface via the adjustable foot component.
