Can u convert from Lpg 2 natural gas and where would u get the correct jets?

Yes you can. you will need to replace the burner orifices, pilot orifice, and spring in the gas valve. Contact the dealer of the equipment that you are using with the model and serial number of the appliance. They should be able to hook you up with a conversion kit. You can probably do this over the internet by searching the appliance manufacturers web-site.
