1. Drill or cut a 4.25’’ round hole or 4.25” x 4.25” square hole in the structural member like plywood or exterior wall material.
    

2. From inside of the structure insert long end of the VENT OUT™ into the exterior hole and lay flange tight against the wood.  Secure flange to the wall with ½” or longer size screws through at least four of the six pre-drilled holes.
    

3. Slip inner duct pass the anti-slip ring around the VENT OUT™. Tightly secure flexible duct to the tube with a zip tie. Note: the anti-splip ring prevents the flexible duct from detaching.
   
   FOR METAL DUCTS:
   Slide duct onto the VENT OUT™ tube and stop at the annti-slip ring. Secure with two or more screws
    

4. Attach the other end of the flexible or metal duct to the ventilation fan or dryer duct. FOR METAL DUCTS: at least a one foot section of flexible duct is needed to attach the metal duct to facilitate adjustability and fit.
    

5. DURING SIDING INSTALLATION:
   Your siding contractor will push the VENT OUT™ into place to fit the distance between the siding material and the exterior vent caps. 
    

6. Siding contractor will remove the disposal cap of the VENT OUT™ and install the permanent vent cap over the tube, and to the structure.

Note:

Procedure is the same for 6”, 8” or 10” ducts.
