What is the maximum length allowed for a clothes dryer exhaust duct from the dryer to the termination point?

The maximum length allowed for a clothes dryer exhaust duct from the dryer to the termination point is 25 feet. This standard is established to ensure efficient operation of the dryer and to minimize the risk of fire hazards. A longer duct can lead to increased resistance to airflow, which may cause the dryer to overheat or not exhaust moisture effectively.

The specified maximum length takes into account the need for proper venting and air circulation. When the exhaust duct exceeds this length, it can significantly hinder the performance of the dryer, potentially requiring an increase in the duct diameter or additional venting measures to maintain safety and efficiency. It's important that homeowners are aware of these guidelines to ensure their appliances function correctly and safely.
