Greenheck 484645 Flame Sensor Rod

The Greenheck 484645 Flame Sensor Rod is a fire detection component used in compatible burner and heating assemblies to confirm the presence of a flame during ignition and operation. It works by sensing flame conductivity through the rod allowing the control system to verify safe combustion conditions before maintaining fuel flow. The rod is positioned within the burner flame path to ensure accurate signal detection during operation cycles. Commonly used in Greenheck heating equipment, it supports ignition safety sequencing, flame monitoring, and coordinated control feedback between the burner assembly and electronic control module within the heating system.
