What is the maximum allowable length for transition ducts in a dryer installation?

The maximum allowable length for transition ducts in a dryer installation is 8 feet. This requirement is based on standards set to ensure efficient operation and safety in dryer systems. Transition ducts, which are used to connect the dryer to the venting system, must be kept as short as possible to minimize the risk of lint buildup and to promote effective airflow. Longer ducts can lead to reduced dryer performance, increased drying times, and a higher risk of fires due to accumulated lint. The 8-foot maximum establishes a balance between practicality and safety, ensuring that the dryer can operate effectively while adhering to code regulations.
