The primary function of a Low Water Cut Out on a low-pressure boiler is to cut off the fuel supply. This safety device is designed to protect the boiler from operating with insufficient water levels, which can lead to overheating and potential boiler damage or failure. When the water level in the boiler drops below a certain point, the Low Water Cut Out activates and interrupts the fuel supply to the burner. This action helps prevent dangerous conditions that could arise from dry firing or running the boiler without adequate water, ensuring safe and efficient operation of the system.

Maintaining water levels is essential for operational efficiency and safety, but the Low Water Cut Out specifically focuses on fuel supply interruption as a direct response to low water conditions. Other options like regulating steam pressure or controlling furnace temperature are functions served by different components, but they do not address the immediate safety concern related to low water conditions.
