What is the primary function of a damper?

To increase combustion temperature
To regulate airflow and flue gases
To enhance fuel efficiency
To distribute heat evenly

The correct answer is: To regulate airflow and flue gases

The primary function of a damper is to regulate airflow and flue gases within a heating system. This component plays a crucial role in controlling the volume of air that enters or exits a system, which can significantly affect combustion efficiency and overall system performance. By adjusting the damper, a technician can optimize the draft in a chimney or flue, helping to ensure that exhaust gases are properly vented outside while allowing adequate air for combustion. This regulation is critical not only for maintaining efficient and safe operation of gas appliances but also for minimizing harmful emissions and ensuring that the system operates within safe parameters. Proper damper adjustment can lead to improvements in safety and efficiency, making it an essential function in heating and ventilation systems. The other options may seem related to performance but do not directly address the fundamental role of a damper. While increasing combustion temperature and enhancing fuel efficiency can be outcomes of a well-regulated airflow, they are not the primary roles of a damper itself. Similarly, distributing heat evenly pertains more to the design of the heating system rather than the specific function of a damper.
