Fully Ducted System – Best Conguration
Fully Ducted System
The fully ducted system has the highest ventilation eectiveness. It is especially suited for
homes without forced-air systems used for both heating and cooling. Dedicated exhaust
grilles draw stale air from service rooms. Dedicated supply registers provide fresh air to main
living areas and bedrooms. Grilles should be located high on a wall or in the ceiling. Grilles
that diuse the air are recommended. Special care should be taken in locating grilles in the
oor. Areas under baseboard heaters will help temper the air. See “Locating the Exhaust Air
Grilles or Registers” page 13 and “Locating the Air Grilles of Diusers” page 13 . Also refer to the
installation instructions included with these products (sold separately).
This system is not connected to an Air-Handling Unit (AHU) or furnace. This system is
normally balanced on high speed. If Aldes patented* Zone Register Terminals (ZRT®) are used
for exhaust or supply registers, balancing must be done at normal operating speed.
