Blower Considerations
Downdraft models DD30I, DD36I and DD45I include a 500
CFM internal blower. In-line and remote blower assemblies
are available for models DD30R, DD36R and DD45R
through your authorized Wolf dealer. For local dealer infor-
mation, visit the showroom locator section of our website,
wolfappliance.com.
Blower options vary with the cooking surface, the volume
of air that needs to be moved and the length of the duct
run. A straight, short duct run with a limited number of
elbows and transitions will allow the downdraft to perform
most efficiently. A remote-mounted blower will minimize
the amount of blower noise, but will not eliminate the
noise completely.
Refer to ventilation recommendations in the Wolf design
guide found on our website, wolfappliance.com.
Ducting Considerations
IMPORTANT NOTE:
Consult a qualified HVAC professional
for specific installation and ducting applications.
Downdraft models with an internal blower have a
3
1
/
4
" (83) x 10" (254) duct and remote blower models
have a 3
1
/
4
" (83) x 14" (356) duct. Each can be transitioned
to 8" (203) or 10" (254) round ductwork. All downdrafts
have an adjustable discharge.
For best performance, 10" (254) round ductwork is recom-
mended. 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 transi-
tions. Check the location of floor joists, wall studs, electri-
cal wiring and plumbing for possible interference with the
ductwork. Refer to the illustrations below for ducting
options.
