Recently noticed my tubes are somewhat worn. Nothing major, but I’m gonna look into a replacement set to have on hand for the future. It looks like the tubes are not slot specific, meaning the same tube could go in anyone of the slots. Does anyone know if this is true? Or is there a specific tube for each slot (front, middle, rear)?

Good question. On some stoves they are different but on the i2400 the parts are all listed with the same part number - 033-953. It looks like all 4 are identical.
