Low Water Cut-Offs

Low water cut-offs that shut down a boiler burner if water level drops. The collection includes Hydrolevel 24 volt cut-offs for gas water boilers, a Hydrolevel 120 volt manual reset cut-off for gas and oil, and a Taco 24 VAC manual reset cut-off with 3/4" NPT foam compensating probe and test button.

Match the control voltage, 24 V or 120 V, to the boiler wiring, and choose automatic or manual reset as code requires. Check probe length and thread for the tapping on the boiler or tee. Many codes require a low water cut-off on boilers above the equipment, so confirm local requirements.
