Connecting ducts to non-dedicated vents is considered not allowed because it can lead to several significant issues in ventilation systems. Non-dedicated vents are not designed to handle the airflow or exhaust from the specific equipment or areas they serve, which can result in inadequate ventilation, poor air quality, and potential safety hazards. This practice can also disrupt the performance of heating or cooling systems, leading to inefficiency and increased energy consumption. The mechanical code emphasizes the importance of using dedicated vents to ensure that each system operates effectively and safely, maintaining the integrity of the building’s HVAC design. Therefore, adherence to the mechanical code prohibits such connections to ensure the well-being of both the occupants and the system.
