The term 'cannot be rendered inoperative' in reference to a low-water cut-off device (LWCO) means that no valves or other devices can be installed that would interfere with its function or disconnect it from the system. It must always remain operational to ensure boiler safety.
More Information
Low-water cut-off devices are crucial in preventing boilers from operating when the water level is too low, which could lead to overheating and potential damage or explosion. Therefore, ensuring these devices cannot be disabled is a key aspect of boiler safety regulations.
Tips
Confusing 'cannot be rendered inoperative' with completely disallowing maintenance can be a mistake. The regulation means the safety device must remain functional during normal operation.
