The correct approach in designing forced draft systems and portions of induced draft systems during operation is to ensure that they prevent the leakage of flue gases into the building. Flue gases can be harmful as they may contain toxic compounds like carbon monoxide, which is a serious health hazard. Proper design limits the potential for these gases to escape into living or working spaces, thereby protecting the health and safety of occupants.

Maintaining a sealed system that effectively contains and directs flue gases to proper venting systems is critical. By preventing leakage, you ensure compliance with safety standards and regulations, which are designed to safeguard against exposure to hazardous gases. Additionally, a well-designed system enhances the efficiency and effectiveness of the combustion process by maintaining proper draft conditions.

Ensuring that excess flue gases are handled correctly, preventing condensation, and promoting airflow are important considerations, but the primary focus of forced and induced draft systems is the containment and safe conveyance of flue gases outside the structure.
