Engineered to monitor \u003cstrong\u003einlet gas pressure\u003c\/strong\u003e, this \u003cstrong\u003eOEM replacement part\u003c\/strong\u003e ensures that your heating system operates within safe hydraulic and pneumatic parameters. This switch is typically integrated into the \u003cstrong\u003eNURO control system\u003c\/strong\u003e or legacy Patterson-Kelley platforms, where it functions as a manual-reset safety limit to prevent overfire conditions and potential damage to the \u003cstrong\u003egas valve train\u003c\/strong\u003e or burner assembly.\u003c\/p\u003e\n\n\u003cp\u003eBuilt for precision, the \u003cstrong\u003e26-0000-0297 pressure switch\u003c\/strong\u003e detects excessive pressure spikes that exceed the specified set point, immediately interrupting the \u003cstrong\u003eburner ignition sequence\u003c\/strong\u003e to provide fail-safe protection. For field technicians, this component offers reliable performance in high-demand environments, including \u003cstrong\u003eP-K SONIC\u003c\/strong\u003e and \u003cstrong\u003eP-K STORM\u003c\/strong\u003e boiler applications. Utilizing a genuine \u003cstrong\u003ePatterson-Kelley pressure switch\u003c\/strong\u003e maintains the integrity of the original equipment's combustion safety profile and prevents unnecessary downtime caused by inconsistent secondary market components.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Benefits:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eEnsures \u003cstrong\u003ecombustion safety\u003c\/strong\u003e by preventing overpressure in the gas line.\u003c\/li\u003e\n  \u003cli\u003eDirect \u003cstrong\u003eOEM replacement\u003c\/strong\u003e for seamless compatibility with Patterson-Kelley hydronic systems.\u003c\/li\u003e\n  \u003cli\u003eSupports \u003cstrong\u003emanual reset\u003c\/strong\u003e functionality for positive lockout and professional diagnostic verification.\u003c\/li\u003e\n  \u003cli\u003eDesigned for integration with \u003cstrong\u003ehigh-efficiency commercial boilers\u003c\/strong\u003e and \u003cstrong\u003ewater heaters\u003c\/strong\u003e.\u003c\/li\u003e\n  \u003cli\u003eDurable construction maintains calibration accuracy in rigorous mechanical room conditions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eCommon Questions:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat causes a high gas pressure switch to trip on a Patterson-Kelley boiler?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTrips are typically caused by a malfunctioning upstream \u003cstrong\u003egas pressure regulator\u003c\/strong\u003e, a sudden surge in building supply pressure, or an improperly adjusted gas manifold. If the \u003cstrong\u003e26-0000-0297\u003c\/strong\u003e trips, a full inspection of the gas train regulators is required before resetting.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow do I reset the 26-0000-0297 switch?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis is a manual-reset safety device. Once gas pressure returns to the normal operating range, the technician must manually depress the reset button on the switch housing to clear the \u003cstrong\u003eHIGH GAS PRESSURE\u003c\/strong\u003e lockout on the boiler control interface.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan this switch be used for both Natural Gas and Propane (LP) systems?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, the switch is compatible with multiple fuel types provided the system operating pressure is within the adjustable range of the switch and adheres to the boiler’s \u003cstrong\u003emaximum inlet pressure\u003c\/strong\u003e rating of 14 inches W.C.\u003c\/p\u003e\n\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
