What is one common resolution for excessive spillage of flue gases?

Increase appliance efficiency rates
Perform regular maintenance
Adjust the draft diverter
Check for vent blockages

The correct answer is: Check for vent blockages

Excessive spillage of flue gases can indicate that the venting system is not functioning properly, which may be due to blockages or restrictions in the venting. Checking for vent blockages is crucial because any obstruction can prevent flue gases from safely exiting the appliance and can lead to dangerous situations, including carbon monoxide buildup in the living space. By ensuring that the vent is clear, you can promote proper airflow, enhance the efficiency of the appliance, and maintain safe operating conditions. Regular inspections and maintenance of venting systems can help identify and rectify potential blockages, ensuring that flue gases are safely expelled. While adjusting the draft diverter or increasing appliance efficiency could potentially help with some spillage issues, these solutions do not address the immediate need to ensure clear venting. Performing regular maintenance is important for overall appliance health, but without checking the vent for blockages first, you may miss a critical factor contributing to flue gas spillage.
