Each burner orifice would have to be replaced to the proper size specified for natural gas. Additionally, the propane regulator needs to be replaced with one for natural gas.

No need to do anything with the regulator. Natural gas as supplied to your house is already regulated, usually around 5-7 inches WC.

You can drill the orifices of your grill to get the proper size. There is a nice table located here: http://www.joppaglass.com/burner/lowp_chrt.html

Of course, if you ever want to change back you can't "undrill" the orifices. You will need to buy new ones.

mmmm no expert here..but I just don't think this is a good idea. Call the manufacturer and see if they have a conversion kit. Some do, some don't.

Even though the house supply is regulated, an appliance regulator is still needed. This is no different than if it was a range with the exception that the range's appliance regulator is built in. Granted, the grill will work with out it but it's best to have it there. This is so if there is an over pressurization from the house regulator, the appliance is still protected. This acts the same as a gas control valve on a hot water heater or furnace and an appliance regulator on a range.

These regulators are generic LP/Nat convertible and can be found at any appliance part store.

"re drilling"

Yes the orfice can be "redrilled" back to LP after being drilled for natural . They have plugs in which you can fit in the orfice. So yes they can be redrilled , but easer to just change them back to natural. And may I add that drill chart is very limited.
