SEPARATION OF TURNS
Separate all turns by at least 3ft. (lm) of straight duct, including distance between last turn and
dampened wall cap. Iftwo turns must be closer than 3ft. (lm) deduct 10ft. (3m) from the maximum
lengths shown in the table for each occurrence.
TURNS OTHER THAN 90°
One turn of 45°or less may be ignored.
Two 45°turns should be treated as one 90 °
Each turn over 45°should be treated as one 90 °.
SEALING OF JOINTS
All joints should be tight to avoid leaks. The male end of each section of duct must point away from the
dryer.
Do not assemble the duct work with fasteners that extend into the duct. They will serve as a collection
point for lint.
Duct joints can be made air and moisture-tight by wrapping the overlapped joints with duct tape.
INSULATION
Duct work which runs through an unheated area or is near an air conditioning duct, should be
insulated to reduce condensation and lint build up and be sloped down toward outdoors.
NOTE: Never install screen inside exhaust duct.
WARNING: THIS MACHINES MUST BE EXHAUSTED OUTDOORS WHEN OPERATED IN THE
VENTING MODE. THIS IS TO PREVENT LARGE AMOUNTS OF LINT AND MOISTURE FROM
ACCUMULATING AND TO MAINTAIN DRYING EFFICIENCY.
