What is prohibited regarding clothes dryer exhaust ducts?

The prohibition against connecting clothes dryer exhaust ducts to a vent connector, vent, or chimney is rooted in safety and performance standards established by the North Carolina Mechanical Code. Clothes dryer exhaust systems are specifically designed to expel moisture and lint out of the home. If these ducts were attached to a vent connector or chimney, it could lead to several issues, including the buildup of lint in areas not designed for it, obstructing airflow and posing a fire hazard. Furthermore, it could allow exhaust gases from heating appliances to backdraft into the dryer, creating dangerous conditions within the home. Therefore, code regulations clearly dictate that dryer exhaust must be directed outdoors without merging with systems that serve different purposes, ensuring both efficiency and safety.
