Kenmore Elite Gas dryer

I got this dryer years back and it says natural gas on it. and I can’t remember putting in different orifice for Propane and unless sears did it for me , I must have been using the wrong orifice in this for all these years , first is that possible.
The second part if Sears did put in a orifice for propane. I hav eot change it because I’m going to hook it up to natural gas. I Bought a natural gas orifice for it, so I can replace that but is there something else I have to do with this model to convert it. Someone said maybe I might have to change the limiter, regulator and a spring that all goes together to convert it completely. Does anyone have this information for this specific dryer.
