The%ducting%from%this%fan%to%the%outside%of%the%building%has%a%strong%effect%on%the%airflow,%noise%and%energy-
use%of%the%fan.%Use%the%shortest,%straightest%duct%routing%possible%for%best%performance%and%avoid%installing%the%
fan%with%smaller%ducts%than%specified%in%this%manual.%Insulation%around%the%ducts%can%reduce%energy%loss%and%
inhibit%mold%growth.%Fans%installed%with%existing%ducts%may%not%achieve%their%rated%airflow.%Do%not%install%the%
