Sensible users will always check the size of the flame under the canner, it's supposed to heat the bottom and not the sides. In a former thread on this topic a highly qualified Tvilian demonstrated with math that a vent could only evacuate a given quantity of steam at a given pressure. Too much heat could make a canner explode, even if the valve was juggling at its maximum speed.
