Description
The Utica-Dunkirk 240010151 is a factory-specified pressure switch designed as a direct OEM replacement for compatible Utica-Dunkirk boiler systems. Rated at 1.72″ water column (WC), this switch monitors combustion air pressure to verify that the draft inducer is operating correctly before allowing the burner to fire — a critical safety function in modern induced-draft and condensing boiler applications.
When the inducer fails to establish the proper negative pressure, the pressure switch prevents ignition, protecting the heat exchanger and ensuring safe, code-compliant operation. Using the correct OEM part guarantees accurate setpoint calibration and reliable performance over the life of the appliance.
