Abstract
The present invention is embodied in a conversion kit for a gas grilling appliance with rotary valves that avoids the need to use either a sleeve inserted in the inner chamber of the regulating plug or interchangeable knobs on the valve shaft. The conversion kit comprises a regulating device for each valve that can be readily installed by removing the existing control knob, placing the regulating device on the valve shaft, and replacing the control knob. The regulating device cooperates with a stop structure on the control panel to limit rotation of the control knob, when converting the grilling appliance from one type of gas to another.
