AIR FLOW IN TYPICAL INSTALLATION
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)
FRESH AIR INLETS
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.
