Abstract
Abstract A gas supply unit for a portable gas grill which is easily assembled and disassembled to a standard portable gas supply tank. A base member for the grill has a compartment into which the gas inlet tube for the burner element and the gas outlet tube from the gas supply control unit are interfitted in an easily removable manner. In preferred embodiment, the gas outlet tube has a butterfly type bolt for threadable engagement with the compartment to hold it in place inside the inlet tube and the compartment. A support arm which is pivotally attached to a support rack for the base holds the gas supply tank at a determined level. The gas outlet tube with the gas control, the supporting rack and the gas tank all are adapted to be carried within the confines of the base and cover for the grill.
