Lochinvar & A.O. Smith 100113144 Switch 321894-708 offering precise setpoint maintenance acrossThe Lochinvar & A. O. Smith 100113144 Blower Prover Switch is a critical safety component designed for high efficiency water heaters and commercial boilers. As a direct OEM replacement for NS2 1333 01, this pressure switch (often referred to as an air pressure switch or draft prover switch) monitors the differential pressure created by the inducer motor. By verifying stable airflow, it ensures the sequence of operation proceeds to ignition safely.
