These are all the gas conversion kits for our grills. For Natural Gas (NG) you will receive replacement orifices which you will screw onto the valve. You need to remove the regulator and have your gas installer hook up to your gas supply.
For the conversion to Liquid Propane (LP) you will receive orifices which screw onto the valves and a hose and QC fitting regulator. The hose may never be connected at the inside of the chassis. You must run black pipe or soft copper lines to the outside before attaching the rubber hose.
