INSTALLATION INSTRUCTIONS
ISLAND HOOD INSTALLATION
INSTALL DUCTWORK
IMPORTANT NOTE:
Consult a qualified HVAC
Engineer for specific ducting applications.
Decide where the ductwork will run between
the hood and the outside. A straight, short
duct run will allow the hood to perform more
efficiently. Limit the number of elbows and
transitions to as few as possible. Long duct
runs, elbows and transitions will reduce the
performance of the hood. Wolf recommends
the maximum linear duct run be no greater
than 50' (15 m). Always use metal ducting.
Do not use flex ducting.
IMPORTANT NOTE:
All hoods must exhaust
to the outdoors.
IMPORTANT NOTE:
There is a possibility of
noise issues, when using a remote blower with
a short duct run.
Wolf recommends installing a backdraft
damper in all installations. A backdraft damper
is included with the hood. It is built into the
transition from the hood to the duct run. In
cold weather installations a backdraft damper
is necessar
y to minimize the backflow of cold
air into the room.
If you are not installing a remote blower,
always install a roof or wall cap. Connect 8"
(203) round metal ductwork to the cap and
work back towards the hood location. Use duct
tape to seal joints between ductwork sections.
Local building codes may requir
e the use of
make-up air. Consult your local HVAC profes-
sional for specific r
equirements in your area.

To reduce the risk of fire, use only metal
ductwork.
To reduce the risk of fire and electric
shock, install this ventilation hood only
with a Wolf blower. Blower part numbers
