Well, it sounds like I will let the experts do it! I just want to be clear though, this is a stove that is currently using propane and we are switching it over to natural gas. You comments about propane made me wonder if you may be thinking it was going to propane.
I suspect the stove was probably a natural gas stove (isn't that the way they are made?) and was converted to propane for us. But now we have natural gas on the street, so we are going back to the stove as a natural gas stove. Just in case, this makes a difference!
