To protect the outside end of horizontal duct work from the weather, a 90° elbow bent downweird
should be installed where the exhaust exits the building. If the 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.
IMPORTANT: Exhaust back pressure measured by a manometer at each basket
(tumbler) exhaust duct area
should not
exceed 0.3 inches of water column.
SINGLE DRYER VENTING
IMPORTANT: For exhaust duct runs of over 10 feet a minimum duct size of 10-inches
must be used.
When single 8-inch venting is used, the duct work from the dryer to the outside outlet cannot
exceed 10 feet (refer to Ulus. A below). This calculation of 10 feet compensates or allows for the use
of a maximum of only one (1) elbow (which is the outside outlet protection).
