NOTES:

1.Furnace blower may be required to operate when ventilation from HRV/ERV is required. The furnace should be set to run continuously or interlocked with HRV/ERV.

2.A minimum separation of 40 inches (1 m) is required between the two direct connections.

3.The exhaust air connection should be upstream of the supply air connection to prevent exhausting any fresh air.

4.Weatherhood arrangement is for drawing purposes only. Six feet (2 m) minimum separation required. Eighteen inches (460 mm) above grade minimum.

5.Due to the differences in pressure between the HRV/ERV and the equipment it is being connected to, the HRV/ERV's airflow must be confirmed on site, using the balancing procedure found in the installation manual.

*Unit is normally balanced on HIGH speed with furnace blower ON.
