🔧 Why This Part Matters

This pilot assembly is critical for reliable ignition and safe operation of gas fireplaces that use a standing pilot system. Over time, thermocouples or electrodes can wear out or fail. Replacing with a genuine 4021-732 assembly restores stable pilot flame, ensures accurate thermopile voltage, and helps maintain safe gas valve operation.
