This reliable pressure switch monitors airflow within your boiler system to ensure safe and efficient combustion operation. Specifically engineered for use in Lochinvar CH 1801 boilers, the 100166248 provides a precise 0.95 inch water column (WC) activation threshold to verify exhaust and intake integrity. The unit arrives ready for integration, including the necessary tubing for a streamlined installation process.
As an SPDT (Single Pole Double Throw) switch, this component acts as a safety interlock that prevents the boiler from firing if proper venting pressure is not detected. It operates by sensing pressure differentials across the system, signaling the ignition control board to proceed only when airflow meets the manufacturer's specified safety parameters.
Key System Performance Baselines:
- Precision Calibration: Factory-set at 0.95 IN WC for exact venting safety requirements.
- Safety Interlock: SPDT contact configuration ensures reliable system shutdown if airflow is compromised.
- Complete Integration: Includes essential tubing to minimize field installation time and complexity.
- Durable Construction: Engineered to withstand the thermal demands of high-capacity hydronic environments.
⚠️ Application Profile: This pressure switch is specifically compatible with Lochinvar Copper-Fin CB and CW series boilers and water heaters, model range 987 through 2067, as well as the CH 1801 series.
