LP to Natural Gas Conversion

Many people buy LP gas grills and wish to convert them to natural gas. The market is saturated with LP grills which are usually cheaper, while natural gas grills are fewer and usually more expensive. 

Sometimes the manufacturer will provide a conversion kit or have one available to order.Converting the grill to natural without a factory kit could violate the warranty and failure to carry out the procedure in a safe way could result in a fire and injury.

If you haven’t done this before you must research the procedure and be certain of the safety before beginning.If you search for “gas grill conversion” on the web, you’ll find numerous sites with kits and some by individuals who have successfully converted their grill from LP to natural gas.

Converting your grill from  LP to natural gas requires changing the orifices (jets) on each valve, Most valves will work with LP or natural but some are made only for one or the other. The oldDucane grills will likelyrequire changing the valves if converting from natural to LP.

All of the holes in the valves are larger for natural gas than for LP, which is why its harder to convert from LP to Natural. You might also find that in converting from LP to natural gas the low flame setting results in little or no flame, but you can adjust for that by simply setting your low flame slightly closer to the medium setting.

Converting to natural gas usually doesn’t require a regulator but sometimes when the pressure is more than 7 inches a regulator might be needed. The LP regulator won’t work for this and you’ll have to get one from a heating supply store.

Since the orifices and other openings in the valves are smaller for LP you might be able to drill out the orifices without further adjustment.
