The HTP 7855P-031 Flame Detector Sensor verifies burner flame presence by sensing combustion and sending a confirmation signal to the ignition control. Its sensing element responds to the flame condition while mounted near the burner for direct detection. The sensor provides combustion-status feedback to the control circuit in HVAC systems, allowing the ignition sequence to respond when flame presence changes. When the detected flame condition is lost, the control can act according to its programmed safety sequence. This continuous flame verification maintains direct feedback between the burner and ignition control during heating operation.
