Stale air exhaust ductwork
Stale air exhaust ductwork
• Install the stale air exhaust registers where the contaminants are
produced: kitchen, living room, etc. Position the registers as far from
the stairway as possible and in such a way that the air circulates in
all the lived-in spaces in the house.
• If a register is installed in the kitchen, it must be located at least
4 feet from the range.
• Install the registers 6 to 12 inches from the ceiling on an interior wall
OR install them in the ceiling.
• If possible, measure the velocity of the air flowing through the
registers. If the velocity is higher than 400 ft/min, then the register
type is too small. Replace with a larger one.
Fresh air distribution ductwork
• Install the fresh air distribution registers in bedrooms, dining rooms,
living room and basement.
• Keep in mind that the fresh air registers must be located as far as
possible from the stale air registers.
• Install the registers either in the ceiling or high on the walls with air flow directed towards the ceiling. (The cooler air will then cross
the upper part of the room and mix with room air, before descending to occupant’s level.)
• If a register must be floor installed, direct the airflow up the wall.
WARNING
!
Never install a stale air exhaust register in a closed room where a combustion device operates, such as a gas
furnace, a gas water heater or a fireplace.
