Stale air from building ductwork:
• Install registers in areas where contaminants are produced: Kitchen, bathrooms, laundry room, etc.
• Install registers on an interior wall, 6 to 12 inches (152 to 305 mm) away from the ceiling OR install them in the ceiling.
• Install the kitchen register at least 4 feet (1.2 m) away from the range.
Fresh air to building ductwork:
• Install registers in bedrooms, dining room, living room and basement.
• Install registers either in the ceiling or high on the walls with the airflow directed towards the ceiling.
• If a register must be installed in the floor, direct the air flow 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.
• When performing duct connections, always use approved tools and materials. Respect all corresponding laws
and safety regulations. Please refer to your local building code.
