Description
The Crown Engineering CA409 is a direct replacement flame rod designed to replace the Maxon 43078. Flame rods are a critical component in commercial and industrial burner safety systems, providing reliable flame sensing to confirm ignition and maintain safe burner operation. When the burner is firing, the flame rod conducts a small current through the flame to the burner ground, signaling the flame safeguard control that combustion is established. If the signal is lost, the control shuts down the burner to prevent unsafe conditions.
