How should the joints in dryer exhaust ducts be aligned?

The proper alignment of joints in dryer exhaust ducts is crucial for ensuring efficient airflow and reducing the risk of lint buildup or blockages. When joints are aligned in the direction of airflow, it minimizes turbulence, which could lead to reduced efficiency in the venting system. This alignment allows for a smoother passage of air, helping to facilitate the removal of moisture and lint from the dryer to the outside.

Additionally, aligning joints in the direction of airflow reduces the chance of lint accumulating at the joints, as lint particles can become trapped in corners or gaps if the joints are not aligned properly. This can not only impair the dryer’s efficiency but can also pose a fire hazard due to the flammability of lint.

In summary, aligning dryer exhaust duct joints in the direction of airflow optimally supports both performance and safety standards, which are essential considerations in accordance with the North Carolina Mechanical Code.
