Maintaining proper airflow is critical for efficient boiler combustion, and the 100113143 Blocked Inlet Switch serves as a protective safeguard for your system. Designed for compatibility with select Lochinvar and A.O. Smith units, this switch monitors intake pressure to prevent hazardous operating conditions.
This safety component functions by sensing negative pressure within the venting system. If the inlet becomes obstructed, the switch triggers an automatic system shutdown, preventing incomplete combustion and protecting the burner assembly from potential damage.
Key System Performance Baselines:
- Safety Integration: Directly communicates with the ignition control module to halt operation during intake blockages.
- Precise Calibration: Factory-tested to meet specific pressure thresholds for consistent, reliable performance.
- Durable Housing: Encased in high-grade materials designed to withstand the thermal fluctuations of hydronic mechanical rooms.
⚠️ Application Profile: This switch is engineered for specific Lochinvar and A.O. Smith boiler models requiring intake monitoring for code-compliant venting safety.
