Description
The Rheem-Ruud AP15689 Flame Sensor Rod is a detection component used to monitor operation in compatible heating equipment. It detects the presence of a burner flame and transmit a verification signal to the electronic control module during operation. It allows the system to confirm that combustion has been maintained throughout the heating cycle. In HVAC systems, it is installed within the burner assembly, where it is positioned in the flame path to continuously monitor burner status. It plays an essential role in supporting combustion monitoring, operational feedback and coordinated system performance during heating operation.
