The AO SMITH 100110832 is a flue vent (FV) sensor and bracket assembly designed for use in residential and light commercial water heating applications. The sensor monitors flue gas conditions to help ensure safe and efficient operation of the water heater. This assembly includes both the sensing element and its mounting bracket, providing a complete replacement kit. Licensed plumbers and HVAC technicians typically handle installation of this component during routine service or when diagnosing flue system fault codes on compatible AO SMITH water heaters.
This part is suited for gas-fired water heater installations where flue vent monitoring is required. It is commonly replaced when the control system registers a flue sensor fault, when the sensor shows signs of physical damage, or when a scheduled maintenance inspection reveals sensor degradation. The included bracket ensures correct positioning and secure mounting within the flue vent assembly.
Designed as an OEM-style replacement FV sensor and bracket assembly for compatible AO SMITH gas-fired water heaters requiring flue vent sensor service.
Installation should be performed by a licensed plumber or qualified HVAC technician. Before beginning any service, shut off the gas supply and disconnect electrical power to the water heater. Allow the flue vent components to cool fully before handling the sensor or bracket. Follow all applicable local codes and the manufacturer service documentation when replacing flue vent components.
