This 4-inch automatic vent damper motor assembly is a high-quality replacement component designed for gas-fired boilers and hydronic heating systems. Engineered for 24V systems, this motor assembly plays a vital role in increasing the energy efficiency of your heating appliance by automatically closing the flue when the burner is off. This prevents residual heat from escaping up the chimney, reducing fuel consumption and lowering utility costs. Constructed from durable materials for long-lasting performance in high-temperature environments, this vent damper ensures safe exhaust ventilation and reliable operation. It is an essential part for maintaining the safety and performance of residential and light commercial gas heating units.
