The combination temperature and pressure relief valve must be marked with a maximum set pressure not to exceed the maximum working pressure of the water heater. The hourly BTU discharge capacity or the rated steam relief capacity of the combination temperature and pressure relief valve must not be less than the input rating of the water heater
