Description
The BASO Gas Products Y75AA-4 Flame Sensor monitors burner flame presence in gas-fired heating equipment and sends a verification signal to the ignition control system during operation. Commonly applied in furnaces, unit heaters, and other combustion-based equipment, the sensor supports coordinated ignition monitoring within the heating assembly. The 0.114-inch diameter identifies the sensor rod thickness, while the 4.5-inch length supports placement within compatible burner configurations requiring extended flame contact positioning. Used in HVAC systems, this component contributes to burner supervision and ignition sequence operation in residential and commercial heating applications.
