What is the type of damper that cannot be installed in the chimney connector?

The type of damper that cannot be installed in the chimney connector is the manually operated damper. This is primarily due to safety concerns and operational efficiency. Manually operated dampers require physical adjustment by the user to open or close, which means that they might not respond to changes in fire conditions automatically.

In contrast, dampers that are automatically operated or pressure-activated are designed to function without manual intervention and can adapt to varying conditions, thus ensuring safer operation by preventing backdrafts or exhaust gases from entering the living space. Safety shutoff dampers are specifically designed for emergency situations and can close off the flow of gases in the event of a malfunction. The presence of automatic functions in the other types provides an essential safety feature that is critical in minimizing risks associated with fuel-burning appliances. Therefore, the manually operated damper is unsuitable for installation in chimney connectors due to its inherent limitations in maintaining safety and efficiency during operation.
