This Gas Convection Range Conversion Kit contains the orifices needed to convert your natural gas range to use liquid propane. This accessory is specifically designed to be used with several Jenn-Air® ranges; check to see if your model number is compatible. Installing this accessory will require specialized tools, complicated disassembly of the range and prior repair experience. We recommend that you hire a qualified technician to install this kit. If installing yourself, remember to shut off the gas supply to the appliance prior to disconnecting the electrical power.
