Low Water Cut-Off (Optional)

The probe-type low water cut-off automatically shuts down burner whenever water level drops below the probe for more than 2 seconds. A 30-second time delay prevents premature lockout due to temporary conditions such as power failure or air pockets.

High and Low Gas Pressure Switches (Optional)

NOTE: The High Gas Pressure Switch is standard on Models 3001-4001

These switches sense either high or low gas pres- sures and automatically shut down burners if abnormal pressures exist.
