Ductwork Installation
IMPORTANT NOTE:
Wolf downdraft ventilation systems
must be vented to the outside.
IMPORTANT NOTE:
Before cutting the hole in the cabinet
for ductwork, check for interference with floor joists, wall
studs, electrical wiring, plumbing and other obstacles.
•
Cut the hole in the cabinet as well as holes in wall or
floor as necessary for the ductwork.
•
Mount the roof or wall cap and work back towards the
cabinet, attaching all ductwork, elbows and transitions
as previously planned. Tape all ductwork connections
to make them secure and air tight.
•
Connect the ductwork and transition (if required) to the
downdraft. If necessary, loosen the nuts and screws
that hold the blower in place, and slide the blower left
or right to align with the ductwork. Retighten the
screws and nuts. Refer to blower discharge adjustment
on the following page.
For installations where the ductwork is riveted to the unit,
a 3

" (83) x 10" (254) collar is provided for models with
an internal blower and a 3
1
/
4
" (83) x 14" (356) collar is
provided for models with a remote blower. This will allow
the blower to be removed and replaced easily for service
without disturbing the ductwork.
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.
Adjustable Discharge
Wolf downdraft systems have an adjustable discharge that
will allow you to negotiate ducting around floor joists and
other obstacles.
Three different discharge locations are available with side-
to-side adjustment for accurate alignment of ductwork.
Refer to the illustration below for the discharge location
and adjustment that best suits your installation.
To reduce the risk of fire, use only metal ductwork.
