Description
The National Comfort Products 14208318 Flame Sensor is a combustion monitoring element that detects whether a burner flame has been established and remains present during the heating sequence. Its sensing rod responds to the electrical features of the flame and sends a signal to the ignition control in HVAC systems, allowing the control circuit to verify burner ignition. If the expected flame signal is absent, the connected controls can interrupt fuel delivery as part of the safety sequence. The sensor connects to the ignition circuit and is positioned near the burner flame for direct detection.
