Question

Air returns must be low on the wall unless a visual smoke study demonstrates an absence of stagnant air flow
True or false

Answer 1

True. Air returns are typically required to be installed low on the wall or at floor level to help ensure proper air circulation and avoid stagnant air flow. However, if a visual smoke study demonstrates that stagnant air flow is not an issue, there may be exceptions to this requirement based on specific building design or circumstances. It’s always best to consult local building codes and standards for the most accurate guidelines.
