Cleaver-Brooks 817-2263 Ultraviolet Flame Scanner

Cleaver-Brooks 817-2263 Ultraviolet Flame Scanner is a UV flame detector designed for use with Cleaver-Brooks burner and boiler systems. The 817-2263 unit is provided with six-foot leads, enabling flexible routing to nearby control hardware. In operation, the UV scanner monitors flame presence by sensing ultraviolet light emitted by the flame and sends a signal to the burner-management or ignition control to confirm ignition or to indicate flame failure. If the flame is lost, the scanner supports a protective shutdown sequence to prevent unburned fuel buildup. This makes it a critical component in safety interlocks for combustion equipment. Typical applications include industrial boilers and fired heaters where reliable flame sensing is required for automatic control and safe shutdown. The part is a direct Cleaver-Brooks replacement option for systems configured around the 817-2263 scanner and its associated control wiring, and is intended for use with compatible Cleaver-Brooks controls and standard electrical interfaces as part of a flame safeguard solution.
