Sub-Zero Downdraft Ventilation - Manual (Page 13)

IMPORTANT NOTE: For installations where
the ductwork is riveted to the unit, an 83 mm x
254 mm collar is provided for models with an
internal blower and an 83 mm x 356 mm 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.

IMPORTANT NOTE: Wolf ventilation down-
draft 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 or
plumbing.
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.
To reduce the risk of fire, use only metal
ductwork.
