Install Motorized Damper
IMPORTANT: Observe all governing codes and ordinances.
Proper location of the outside air intake is necessary to ensure that the damper can reliably allow fresh air to enter the home. The following requirements for the location of the outside air intake must be met:
■Outside air intake is to be located a minimum of 10 ft (3.05 m) from combustion appliance vents, chimneys, plumbing stacks, and bathroom, laundry, or kitchen exhaust vents.
■Outside air intake is to be placed high enough above grade to prevent blockage from snow or other debris such as leaves, and at a minimum of 1 ft (30.5 cm) above grade.
■The damper should be installed to draw air directly from outdoors. Makeup air should not be drawn from crawl spaces, garages, attics, adjacent dwelling units, or any enclosed part of the building.
Install the motorized damper as shown. See the illustrations in “Typical Installations” in the “Location Requirements” section for reference.
