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 downdrafts must
be vented to the outside. Use only metal
ductwork.
