VENTING REQUIREMENTS
Determine which venting method is best for your application. Ductwork can extend either through the wall or the roof.
The length of the ductwork and the number of elbows should be kept to a minimum to provide efficient performance. The size of the ductwork should be uniform. Do not install two elbows together. Use duct tape to seal all joints in the ductwork system. Use caulking to seal exterior wall or floor opening around the cap.
Flexible ductwork is not recommended. Flexible ductwork creates back pressure and air turbulence that greatly reduces performance.
Make sure there is proper clearance within the wall or floor for exhaust duct before making cutouts. Do not cut a joist or stud unless absolutely necessary. If a joist or stud must be cut, then a supporting frame must be constructed.
