The steam boiler has basic controls to protect the safety and correct operation of the system including the following items:
- Pressure Gauge and Regulator: Monitors pressure and shuts off the fuel supply to the boiler if allowable boiler pressure is exceeded.
- Temperature and Pressure Relief Valve: Releases steam if the pressure gage / regulator fails and pressure builds dangerously high.
- Water Level Sight Glass: Glass tube that shows water level in the boiler.
- Low Water Cutoff: Shuts off system if boiler water level drops below required levels.
