Field Controls 46486901 is a four-inch gas vent damper designed for use with gas-fired appliances. This damper opens to allow exhaust to escape during operation and closes to prevent heat loss when the appliance is off. The unit features dual safety switches to ensure safe operation, preventing the burner from igniting unless the damper is fully open. Its stainless steel construction provides durability and resistance to corrosion, making it suitable for long-term use.
This vent damper minimizes energy loss and enhances the efficiency of gas appliances by sealing the vent when not in use.
