Generated explanation

The illustration shows HRV intake and exhaust hoods on the exterior of a house, with dimensioned placement and separation distances. The intake is shown 40 inches from the building corner and 18 inches above the bottom of the wall, with 6 feet separating it from the HRV exhaust. Another wall termination, identified as a possible dryer vent, exhaust fan vent, combustion-appliance vent, gas meter, or oil fill/vent lines, is shown 3 feet from the intake; the exhaust height is marked 4–8 feet. Side-view details show a required screen at the intake and an exhaust damper that opens during operation and closes when the system is off. Arrows indicate air entering the intake and leaving the exhaust.
