IMPORTANT NOTE: Always consult a
qualified HVAC Engineer for specific ducting
applications.
IMPORTANT NOTE: Wolf ventilation down-
draft systems must be vented to the outside.
Use only metal ductwork.
Wolf downdraft ventilation systems are
designed for use with 3
ductwork for Models DD30I, DD36I and DD45I,
and 3
DD30R, DD36R and DD45R. Each can be
transitioned to 8" (203) or 10" (254) round
ductwork.
For best performance, 10" (254) round
ductwork is recommended. The downdraft will
operate most efficiently when the ductwork
does not exceed 40' (12 m) in length.

Choose the ducting option that allows the
shortest length of ductwork and a minimum
number of elbows and transitions. Check the
location of floor joists, wall studs, electrical
wiring or plumbing for possible interference
with the ductwork. Refer to the illustrations
below for ducting options.
IMPORTANT NOTE: Use duct tape to seal the
connection between the blower outlet and
ductwork. Support the weight of the ductwork
as necessary to ensure sealed joints.
