a. Outside Duct Work Protection

1) To protect the outside end of horizontal duct work from the weather, a 90° elbow bent downward

should be installed where the exhaust exits the building. If the exhaust duct work travels vertically

up through the roof, it should be protected from the weather by using a 180° turn to point the

opening downward. In either case, allow at least twice the diameter of the duct between the duct

opening and the nearest obstruction.

IMPORTANT: DO NOT use screens or caps on the outside of opening of exhaust duct work.
