This is the model number it's a GE gas range not very old at all. Serial # SF234269P Model# JGBP28WEH1WW. I need a manual for this prefer downloaded on line. I also need to know when converting from natural gas to LP do you have to change the oven orfices. I change the stove orfices and it's fine but the oven flames are too high. I already set the air vents to LP from Natural.
