    摘要: A chimney safety and control system includes a control panel which indicates the position of the chimney damper and the operational status of a chimney fan unit, and allows the operator to electro-mechanically open and close the damper and set the fan. When the safety control system senses that a predetermined condition (e.g., high temperature) exists in the chimney firebox while the damper is closed, it automatically opens the damper and activates the fan. The system may also be used in conjunction with one or more smoke detectors, in which case the system automatically opens the damper and activates the fan when a smoke detector is activated.
