PLAN THE INSTALLATION

LOCATION OF DIFFUSERS & INLETS

FRESH AIR INLETS

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 ceilings or high

on the wall.

For best performance, exhaust diffusers should be mounted

in a central location. An exhaust diffuser should not be

installed near a cooking area. (see figure)

FRESH AIR INLETS (Available separately)

For best control of fresh air in a room, install a fresh air inlet.

The number of inlets depend on the floor plan. Consider the

rooms/areas through which fresh air should flow toward the

exhaust diffuser(s).

Inlets should be located in outside walls, preferably near

the ceiling. Each inlet should be approximately the same

distance from a diffuser. Inlets should be separated from

diffusers far enough to allow fresh air to mix with room air

before being exhausted.
