Abstract: A burner assembly for use with a chafing dish having a leg structure for support of a chafing dish above a support surface. The burner assembly includes a butane fuel source or reservoir, a burner head connected to the fuel source, a valve mounted between the fuel source and the burner head to control the flow of butane to the burner head, and burner head support structure supporting the burner head above the support surface. The burner support structure further includes a base having a portion formed for positioning proximate and outwardly of the leg structure of the chafing dish, and an arm portion which is preferably cantilevered relative to the base portion. The arm extends from a position outwardly of the chafing dish leg structure to a position between the chafing dish heater support tray and the bottom of the chafing dish to enable heating of the chafing dish. The base is formed for support of the arm portion and burner head for movement independently of the chafing dish.
