VENTILATOR
The ventilator exhausts stale air. There are normally suffi- cient natural intake openings into a dwelling to admit fresh outside air to be drawn in to replace the stale air. For better control, fresh air inlets may be used.
The ventilator should be centrally located to keep ductwork as short as possible. Locations for the ventilator include: joists in an attic space or the basement, or a wall away from the living areas.

EXHAUST
DIFFUSERS
(Available separately)
Exhaust diffusers regulate the flow of fresh air drawn through the house.
Exhaust diffusers should be mounted in the ceil- ings or high on the wall.
For best performance, ex- haust diffusers should be mounted in a central loca- tion. An exhaust diffuser should not be installed near a cooking area. (see figure)

For best control of fresh air in a room, install a fresh air inlet.
The number of inlet vents depends on the floor plan. Consider the rooms/areas through which fresh air should flow toward the exhaust diffuser(s).
Vents should be located in outside walls, preferably near the ceiling and approximately the same distance from a diffuser. Vents should be separated from diffusers far enough to allow fresh air to mix with room air before being exhausted.
