This application uses a devoted duct system for the exhausting of stale air accumulated in the home.
The fresh air is introduced into the return air duct and is distributed through the home by the existing supply air ductwork of the forced air system.
Make sure when using this application that your fresh air duct connection to the forced air system return air duct is at least 3 feet from the forced air system. You should check with your local code or the forced air system’s manufacturer.
The forced air system’s blower does not have to run when the unit is operating, but is recommended for maximum effectiveness.
NOTE: For the minimum distance between the fresh air connection and the forced air system, check with your local building codes and forced air system manufacturer.
NOTE: For dwellings with multiple forced air systems, Honeywell recommends one ERV/HRV unit per system.
NOTE: Refer to the Wiring section (beginning on page 18) for instructions to connect the unit to operate the forced air system with the ERV/HRV unit.

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).
