What is a specific requirement for the installation of clothes dryers' ventilation?

Must not exceed 14 feet
Should use thermal barriers
Must have a dedicated power supply
Must include a lint trap

The correct answer is: Must not exceed 14 feet

When it comes to the installation of clothes dryer ventilation, one critical requirement is that the ductwork must not exceed a certain length—commonly 14 feet for most residential applications. This limitation is in place to ensure efficient airflow, as longer duct runs can lead to increased resistance, which may cause lint buildup and reduce the dryer’s performance. Effectively managing airflow is essential not only for the dryer’s efficiency but also for safety, as accumulated lint can become a fire hazard. In both residential and commercial settings, adhering to this length restriction helps maintain optimal dryer function and minimizes risks associated with improper venting.
