For best performance, 10" (254) round ductwork
is recommended. The downdraft will operate
most efficiently when ductwork does not exceed
40' (12 m) in length. Consult a qualified HVAC
engineer for specific ducting applications.
IMPORTANT NOTE:
All Wolf downdraft systems
must be vented to the outside. Use only metal
ductwork.
Choose the ducting option that allows the
shortest length of ductwork and a minimum
number of elbows and transitions. Refer to the
illustration below for ducting options for Wolf
downdraft systems.
Refer to the cooktop ventilation charts at the end
of this section for minimum CFM recommenda-
tions and blower options.
