Fully Dedicated System
Installation Notes
The ERV 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 ERV system.
The duct configuration may change depending on the ERV
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”

Check local codes/authority having jurisdiction for acceptance.
Applications such as greenhouses, atriums, swimming pools, saunas, etc. have unique ventilation requirements
which should be addressed with an isolated ventilation system.
Weatherhood arrangement is for drawing purposes only. Check local codes/authority having jurisdiction for
acceptance.
Backdraft dampers are recommended for the stale air to outside air duct. This damper prevents outdoor air from
entering the ERV during the operation of the furnace/air handler while the ERV is in standby, off, or recirculating.
