Wolf cooktop wall and island hoods are shipped
without the blower assembly. Internal, in-line
and remote blower assemblies are available. For
wall hoods, the remote blower can be mounted
on the roof or an exterior wall. For island hoods,
the remote blower will be mounted on the roof.
The blower will vary in size and is dictated by
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 ventilation
hood to perform most efficiently.
A remote mounted blower will minimize the
amount of blower noise, but will not eliminate
the noise completely. All remote blowers will
require a transition to a 10" (254) duct.
IMPORTANT NOTE: Install these ventilation
hoods only with a Wolf blower.

IMPORTANT NOTE: All Wolf cooktop hoods
must be vented to the outside. Use only metal
ductwork.
Wolf cooktop wall and island hoods have an 8"
(203) round vertical discharge. Ducting can run
through the roof, external wall or eave. Ducting
through an eave requires an internal blower.
Refer to the illustrations below.
Wolf cooktop wall and island hoods will operate
most efficiently when ductwork does not exceed
50' (15 m) in length.
Local building codes may require the use of
make-up air. Consult your local HVAC profes-
sional for specific requirements in your area.
Refer to the cooktop ventilation recommenda-
tions on pages 115–116.
