What is the minimum distance required from mechanical air intakes to exhaust openings?

The minimum distance required from mechanical air intakes to exhaust openings is 10 feet. This requirement is established to prevent potential cross-contamination of air streams and ensure that the outdoor air being drawn into the mechanical system is clean and unobstructed. By maintaining this distance, the intake can avoid drawing in exhaust gases, odors, or pollutants emitted from nearby exhaust sources, which can negatively impact indoor air quality and the efficiency of the HVAC system.

Additionally, this regulation is part of ensuring that the systems operate optimally and safely. Having a minimum distance also allows for better airflow dynamics, reducing the likelihood of recirculating stale or contaminated air back into the building.
