•3. to damage resulting from operation with either the flame sensor rod or overheat sensor removed;

•4. to failure of the heat exchanger resulting from the operation of the water heater in a corrosive atmosphere or at water temperatures exceeding the maximum rating, or if the water heater is not supplied with potable water;
