In a venting system, what should be avoided to maintain safety?

In a venting system, preventing flue gas leakage is crucial for maintaining safety. Flue gases contain harmful substances such as carbon monoxide, which can pose serious health risks if they leak into living spaces. Properly sealed and functioning venting systems ensure that these gases are safely directed outside, preventing exposure to occupants and minimizing the risk of accidents or health issues.

While it is also important to be mindful of excessive heat, low humidity, or unregulated airflow, these factors do not have the same immediate threat to safety as flue gas leakage. Excessive heat can lead to system inefficiencies or equipment damage, low humidity can affect comfort levels, and unregulated airflow can compromise efficiency, but none directly endanger health to the same degree as allowing hazardous flue gases to escape into a home or facility. Therefore, ensuring that flue gas leakage is eliminated or controlled is paramount in maintaining a safe environment.
