Thanks for your inquiry about the Maytag range, I will be glade to assist with this.
I have researched the model you provided and find no LP conversion kit listed for the model CRS9700BAW.
I have also been unable to locate a service manual. Some models don`t need any parts (orifices) as they can be adjusted oven and top burners and regulator, However I cannot determine that on your model and would suggest having a Certified LP technician out to inspect the range.
Thanks Ron H.
