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.
