Answer:

Ventilation ductwork is not provided with Wolf Ventilation systems, nor does Wolf sell ventilation ductwork.

  • Ductwork can be purchased from most local hardware, home improvement stores, or HVAC suppliers.
    • Ducting may be a special order item in some locations.
  • Do not use flexible metal ducting.
    • Flexible metal ducting will increase air resistance and is not recommended by the National Uniform Mechanical Code Standards.
  • Wolf does not specify the exact style, type or brand of roof, or wall cap needed for a ventilation system.
    • Wolf does not sell roof or wall caps.
    • Roof or wall caps can be purchased from most local hardware, home improvement stores, or HVAC suppliers.
    • It may be a special order item in some locations.
  • Municipality requirements may be more restrictive than Wolf's recommendations. Refer to local code for specific information.
  • Use of smaller than recommended diameter ductwork will not create a fire hazard. However, a smaller duct will move less air, which may hinder ventilation performance (for example, more carbon monoxide, smoke, or odors in the home).
  • Single wall ducting is adequate.
