Do burners (above a stove) have a halacha as pareve? Like if one wants to heat a food item directly on burners like bread for example may he use that bread for meat or dairy?
If it depends, what does it depend on?
It isn’t clear to me what you mean by burners. If you are referring to the round piece of metal that the actual fire comes out of, that is self kashering. If you are referring to the grates on top of that, (the placed that the pots are placed upon), then it depends. The part that comes in contact with the fire, gets very hot and is like it is self kashering, therefore you can put the bread over there, and eat it with meat or dairy. The other part of the grates would be problematic.
