Couple of things. First, NG orifices have larger openings than LP. So, if you don't modify or change the orifice, you will get a lower flame which could be an issue. Second is the actual plumbing. On the SSP the on/off valve is on the tank itself. Since the tank will be gone, you'll need to have the on/off valve somewhere else which might be less convenient. Then you would need a NG hose. The connector on the end probably won't fit right up to the SSP,, but you can use brass adapter fittings from a hardware store to match up.
