Blower Considerations
Except for Models DD30I and DD36I,
which include a 500 cfm internal
blower, Wolf downdrafts are shipped
without the blower assembly. Remote
blower assemblies are available. The
blower will vary in size and is dictated
by the cooking surface and the
distance to the exterior of the home.
Blower options also vary with the
volume of air that needs to be moved
and the length of the duct run.
IMPORTANT NOTE: Install this
downdraft only with a Wolf blower.
Refer to the cooktop ventilation
charts on pages 79-80 for recommen-
dations and blower options.
Ducting Considerations
IMPORTANT NOTE: All Wolf ventila-
tion products must be vented to the
outside. Use only metal ductwork.
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.
Choose the ducting option which
allows the shortest length of
ductwork and a minimum number of
elbows and transitions. Refer to the
illustration for ducting options.
