but ensure your sensing lines (1/4" FR tubing) are clear of debris and that the differential pressure sensor is not calibrated outside its 0-2" wc range

Can I use a 115V motor as a substitute

it provides real-time diagnostics of the liquid line’s condition

while the automatic reset capability reduces onsite maintenance requirements

Efficiency Optimization: Reduces off-cycle heat loss by sealing the flue when the boiler is not firing

Lochinvar & A.O. Smith 100208665 Low Water Cutoff Els PW 29614 but ensure your sensing linesThe Lochinvar & A. O. Smith 100208665 Low Water Cutoff is a critical safety component designed for high efficiency hydronic boilers and water heating systems. This probe style LWCO provides essential dry fire protection by monitoring the water level within the heat exchanger. If a low water condition occurs, the sensor interrupts the burner circuit to prevent catastrophic equipment failure. Engineered as an automatic reset Low Water Cutoff, it
