How long can domestic clothes dryer transition ducts be limited to for a single length?

For domestic clothes dryer transition ducts, the maximum allowable length for a single duct run is typically 8 feet. This length is established to ensure efficient airflow, preventing lint buildup and ensuring that the dryer operates effectively without overheating. Transition ducts are designed to connect the dryer to the venting system, and their length can impact the dryer’s performance and safety.

Extending beyond this limit can lead to reduced efficiency and increased risk of fire hazards due to lint accumulation. Maintaining proper duct length is crucial for energy efficiency and appliance longevity. Therefore, the correct answer reflects the standard guidelines in appliance installation and safety recommendations.
