This Natural Gas Range High Altitude Conversion Kit includes the necessary orifices to adjust your natural gas range to operate properly in elevations that exceed 6560 ft (1999.5 m). At higher altitudes where air pressure is lower, cooking temperatures need to be increased to bring water to boil or thoroughly cook your food. If you ve experienced these issues, you can update your natural gas range with this kit. This is a universal accessory that can be used across several brands; check your appliance s model number to confirm compatibility. 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 conversion kit. If installing yourself, remember to unplug the range or shut off the house circuit breaker for the appliance before installing this part. Also make sure to turn off the gas valve before the repair.
