How must concealed metal ducts for gas dryer vents be maintained?

Concealed metal ducts for gas dryer vents must be maintained without any deformation to ensure their effective functioning and safety. When ducts are deformed, it can restrict airflow, leading to poor ventilation. This can create the risk of lint buildup, which is a fire hazard, especially in dryer vent systems. Maintaining the integrity of these ducts is vital, as even minor bends or alterations can interfere with exhaust performance and increase the likelihood of carbon monoxide buildup, which is particularly dangerous in gas appliances.

In addition, proper maintenance of ductwork is essential for compliance with building codes and safety regulations, which typically require that venting systems be straight and free from obstructions or deformities. Using ducts that are bent or otherwise altered can also lead to inefficient dryer operation, increasing energy consumption and reducing the lifespan of the appliance. Keeping these ducts intact and properly aligned ensures that they will vent gases effectively and support the proper operation of the dryer.
