The LP conversion kit instructions for this gas range are provided in the images below. These instructions have the sizes and markings of the original natural gas orifices that were on the range. It provides instruction for converting the range to LP and also for changing it back to natural gas. If you do not have the natural gas orifices and the range is set up for LP gas, then I recommend that you order the original natural gas orifices for the range from the
website and have a qualified installer convert the range to natural gas if that is the fuel that you are now using for the range.
I recommend that you use a pre-screened professional from the
website to convert the range if necessary. This website has qualified gas technicians in most areas that can properly convert the range to natural gas.
