Supco FLS301 Flame Sensor

The Supco FLS301 Flame Sensor is a safety device crucial for gas-fired HVAC equipment like furnaces and boilers. It safeguards against gas leaks by detecting the presence of a flame using a heat-sensitive probe. If the flame unexpectedly extinguishes, the sensor sends a signal to the control board, which promptly shuts down the gas supply. This vital safety feature helps prevent dangerous gas leaks and ensures the safe operation of your HVAC system. The Supco FLS301 is compatible with both liquid propane and natural gas systems. It measures compactly at 7/8 inches wide by 6 1/4 inches long by 1/2 inch thick, with a 3-inch probe length. After a brief 17-second warm-up period, the sensor is operational and ready to safeguard your HVAC system.
