Hello DNW, this is Roland. Thank you for your purchase and feedback.
I was sorry to hear that you were not completely satisfied with our product and I want to make sure that we address all your concerns. The natural gas orifices are included with the grill. The 4 main burner gas valve orifices for propane and natural gas are pre-installed. You would only need to remove the propane orifices. The natural gas orifice for the rotisserie burner gas valve comes in a plastic bag with the manual package. Please refer to the Gas Conversion section of the owner's manual in the link below for step by step conversion instructions: https://images.thdstatic.com/catalog/pdfImages/f5/f52bc67e-a663-4427-9d28-18d7fc64e2df.pdf
Please feel free to reach out to us at 800-913-8999 if you would need further assistance. Thank you for your valuable feedback and we look forward hearing from you. Thank you again from all of us at The Grill Services!
