·
Dryer exhaust duct should enter the main duct at an angle of no more
than 30
o
pointing in the direction of the air flow. Ducts entering the
main duct from opposite sides should be staggered so as not to
oppose each other, see illustration below.
·
Provisions should be made for periodic lint removal and cleaning of the
main collector duct.
·
The outside end of the main duct should have a weather hood (with
hinged damper) installed to prevent passage of weather elements,
insects, dust, and dirt into the dryers.
·
If a weather hood cannot be used, the outside end of the main duct
should have a sweep elbow installed, and be directed downward as
shown on page 38. If the main duct travels vertically through a roof
rather than through a wall, install a 180
o
sweep elbow on the end of
the duct with outlet at least 24 inches (60.96 cm) above the highest
part of the building.
To reduce the risk of fire and the accumulation of
combustion gases, DO NOT exhaust dryer air into a
window well, gas vent, chimney or enclosed,
unventilated area, such as an attic, wall, ceiling, crawl
space under a building or concealed space of a building.
