Application
Heat Recovery Ventilators (HRV) are designed to provide
fresh air while exhausting an equal amount of stale air.
The HRV is equipped with an aluminum core. The device
uses the stale air that is being exhausted to condition the
fresh air as it is being brought in.
General
These instructions are intended as a general guide and do
not supersede local codes in any way. Consult authorities
who have jurisdiction before installation.
