Flexible air connectors are prohibited from passing through which of the following?

Flexible air connectors are designed to provide a certain level of flexibility in HVAC systems, allowing for movement and expansion without causing damage. However, they have specific limitations due to safety and performance considerations.

Passing flexible air connectors through walls, floors, and ceilings can lead to several issues, including creating points of potential air leakage, increased wear from rubbing against building materials, and difficulties in maintenance and repair. Smoke and fire could also travel through these areas if a fire were to break out, compromising safety.

The prohibition of these connectors in such structures ensures the integrity of the building envelope, maintains the efficiency of the HVAC system, and minimizes the risk of fire spread or structural failure. By avoiding flexibility connectors in these locations, the system can operate more reliably and meet established code requirements for safety and performance.
