SPECIFICATIONS
Ductwork
WARNING
To reduce the risk of fire, use only metal ductwork.
6" round, rigid metal duct is recommended for cooktop
(152)
ventilation hoods.
A straight, short run is most effective and will ensure proper
operation. For best results, the duct run should not exceed
50' . For runs exceeding 50' , a higher CFM
(15 m) (15 m)
blower may be required to maintain proper air flow and
performance. A remote blower installed on a short duct run
may increase the potential for noise.
Internal and in-line blowers require a roof or wall cap (not
provided). Connect ductwork to the cap and work back
towards the hood. Use sheet metal screws and aluminum
tape or high temperature duct tape to seal joints between
ductwork sections.
Wall and island hoods include a backdraft damper. Local
codes may require the use of an additional backdraft and/or
make-up air damper. Contact your local HVAC professional
for specific requirements.
A make-up air damper is available through an authorized
Wolf dealer. For local dealer information, visit the find a
showroom section of our website, wolfappliance.com.
