Answer Ian, There is no natural gas conversion kit and you will need to get the top burner orifices front left 5304500188, left rear 5304500186. center will need 2 of 5304500187 and 1 of 5304500185, right rear 5304500184, and right front 5304500189. For the oven you will loosen the orifices 1 1/2 to 2 turns and then close the air shutter to about 3/4 of the way open. You will also want to flip the cap on the regulator from LP to Natural.
