How often should the low water fuel cut-off be tested when the boiler is operating?

The low water fuel cut-off is a safety device essential for safe boiler operation. It is designed to shut off the fuel supply to the boiler if water levels drop too low, preventing overheating and potential damage. Testing this device is crucial because it ensures that it will function properly in an emergency situation.

Testing the low water fuel cut-off at least once a day is recommended because it allows for the verification of the device's reliability under normal operating conditions. Daily testing helps to promptly identify any faults that could prevent the cut-off from working when needed. Continuous monitoring ensures that the boiler maintains safe water levels, reducing the risk of accidents and enhancing overall operational safety.

While weekly or monthly tests are helpful, they do not provide the same level of assurance that daily testing offers. Additionally, testing every shift change may not be practical in some operational settings, particularly in larger facilities where shifts overlap, and might not ensure that the device is checked at all times. Therefore, daily testing strikes a balance between safety and feasibility in maintaining boiler operations.
