   Do not exceed the length of duct pipe for the number of elbows shown in the 
chart below.  Doing so can cause an accumulation of lint, increase drying time, 
and create a Þ re hazard. 
   Two 45° elbows equal one 90° elbow.

   All joints should be tight to avoid air leaks.  The male end of each section of 
ducting must point away from the dryer.
   Use clamps or duct tape to connect and seal all joints. 
Do not connect with screws or other fasteners that 
extend into the interior of the duct as they will create a 
collection point for lint.
Clamp
   Avoid running the exhaust system through an unheated area as this will 
cause condensation to form inside the duct and accelerate the rate of lint 
accumulation.
   Avoid running the exhaust system vertically through a roof as this may expose 
the exhaust system to down drafts, causing an increase in air restriction.
   Avoid sagging, compression or crimping of the exhaust system as this will result 
in reduced airß ow and poor dryer performance.
   Do not screen the end of the exhaust system. Lint will accumulate and 
eventually clog the screen. Use an approved exhaust hood to terminate the duct 
outdoors.
