Why does my Riello RTC-80 keep shutting down?

Your Riello Boiler might be shutting down due to several reasons. It could be a control thermostat problem, so check the functioning of the aquastat. Also, check the temperature setting, the electrical wiring and the sensor bulbs. If there's no water supply, check the circuit pressure. Finally, air in the circuit can cause this, so check the vent valve.
