Exhaust and Supply in the Return

When using this application make sure that there is a minimum of 6 feet between the fresh air and

exhaust air connections of the ERV/HRV unit in the return air duct. Supply air from the ERV/HRV unit

must be at least 3 feet from the forced air system. These distances can be different from one region to

another; you should check with your local code or the forced air system’s manufacturer.

NOTE: For minimum distance between return and forced air system, check with your local building

codes and forced air system manufacturer.

NOTE: Fresh air must always be down-stream from the exhaust air in the return air duct of the forced air

system.

NOTE: Furnace blower is required to operate when ventilation is required. Set the furnace blower to run

continuously, or interlock electrically (low voltage).
