Lochinvar & A.O. Smith 100111063 Outlet Switch
The Lochinvar & A.O. Smith 100111063 Blocked Outlet Switch is a critical safety component designed for high-efficiency commercial boiler systems, including the Cyclone Xi BTH-120 and SUF/HCG series. As a veteran-grade HVAC safety device, this switch monitors the exhaust vent for obstructions that could cause hazardous flue gas accumulation or thermal stress on the heat exchanger. If the integrated sensor detects a drop in air flow rate or a blocked flue condition, it instantly breaks the circuit to the control module, initiating a safety lockout to protect equipment integrity and personnel safety. This OEM replacement part is calibrated for precise pressure differentials, ensuring your gas water heater or boiler operates within its engineered performance envelope. When troubleshooting intermittent ignition failures or pressure switch errors, verify the integrity of the reference hoses and contactor points before replacing this essential exhaust vent switch.
Key Benefits:- System Protection: Effectively prevents overheating and the buildup of dangerous carbon monoxide by shutting down the burner during exhaust obstructions.
- Precision Calibration: Specifically engineered for Lochinvar and A.O. Smith boiler models BTH, SUF, and HCG, ensuring accurate response to pressure changes.
- Enhanced Durability: Robust OEM construction withstands the high-temperature environment of commercial venting systems.
- Safety Compliance: Maintains the required safety sequences for high-efficiency commercial water heaters, avoiding costly repairs from thermal damage.
- What causes a blocked outlet switch lockout? Most lockouts occur due to debris in the vent termination, excessive vent lengths, or moisture buildup in the pressure sensing tubes.
- How do I test the 100111063 switch? Using a manometer, verify that the pressure differential at the switch matches the rating on the part label while the inducer is running.
- Is this switch compatible with LP and Natural Gas units? Yes, the 100111063 is designed to work across both Natural and Propane Gas commercial water heater models.
