Fully Dedicated System
Installation Notes
The HRV must be balanced.
When balancing, all external exhaust systems should be
turned off (i.e. range hood, dryer exhaust, bathroom
vents).
All exhausting appliances should have their own make-up
air, as this is not an intended use of the HRV system.
The duct configuration may change depending on the
HRV model.
The airflow must be confirmed on site using the balancing
procedures found in this guide.
Spring-Loaded Backdraft Damper (Recommended)
There is a location for an optional Backdraft Damper with the leaf hinge vertical. The damper is
installed on the “Stale Air to Outside Collar”
