- UL-listed for dryer use
- Short as possible and fully visible
Connection Method
- No screws (they trap lint)
- Foil-backed metal tape (UL 181) used to seal joints
- Secure with hose clamps or approved connectors
Airflow Direction
- Transition duct should not kink or crush
- Male ends of duct point in the direction of airflow
- Entire length has a slight slope downward to the exit
In-Wall or Ceiling Exhaust Duct
Construction Material
- Rigid galvanized steel or aluminum (28-gauge minimum)
- Absolutely no PVC or plastic
Route and Length
- As short and straight as possible
- Minimal 90° turns (each adds resistance)
- Add clean-out access for long or hidden runs
Termination Hood (Exterior)
- Has a backdraft damper
- NO screens
- No bird nest or bee hives
- Minimum 12” above ground
- Points downward to prevent water/rain entry
DO NOT USE
❌ No duct screws

- Used only metal foil heat tape
- Have a smoke detector and a fire extinguisher readily available
- Check for carbon monoxide detectors if a gas dryer is used
