Cooktop Chimney Hood nstallation
IMP RTANT N TE: This installation must be completed
by a qualified installer or Wolf factory certified service.
Read this entire installation guide prior to installation and
save for the local inspector’s reference. The homeowner
should keep this installation guide for future reference.
This appliance must be installed in accordance with
National Electrical Codes, as well as all state, municipal
and local codes. The correct voltage, frequency and
amperage must be supplied to the appliance from a dedi-
cated, grounded circuit which is protected by a properly
sized circuit breaker or time delay fuse. The proper
voltage, frequency and amperage ratings are listed on the
product rating plate.
Record the model and serial numbers before installing the
ventilation hood. Both numbers are listed on the product
rating plate, located inside the left wall of the hood shell,
above the filter. The filter must be removed to access the
rating plate. Refer to the illustration below.

Hood Placement
Wolf cooktop chimney wall and island hoods come with a
telescopic chimney flue that allows you to reach a ceiling
height of 8' (2.4 m) to 9' (2.7 m) with a finished look. A flue
extension to accommodate 10' (3 m) ceilings is available
through your authorized Wolf dealer. For local dealer infor-
mation, visit the find a showroom section of our website,
wolfappliance.com.
nstallation of the cooktop chimney hood should be
24" (610) to 30" (762) from the bottom of the hood to the
countertop. To determine placement of the hood, you
must calculate the height of the telescopic chimney flue.
The minimum and maximum flue extension for each
cooktop chimney hood is listed in the chart.
Both sections of the telescopic chimney flue must be
installed in order for the chimney to be lifted for service.
IMP RTANT N TE: 8' (2.4 m) ceilings may not permit
installation of the wall or island hood at 30" (762) above the
countertop.
CALCULATE CHIMNEY FLUE HEIGHT
A) Height from finished floor to finished ceiling. 8' (2.4 m)
or 9' (2.7 m) ceilings are typical.
B) Height from finished floor to countertop. A 36" (914)
countertop height is standard.
C) Hood mounting height (bottom of hood to countertop).
Dimension C must be between 24" (610) and 30" (762).
8' (2.4 m) ceilings may not allow the maximum 30" (762)
hood mounting height.
D) Calculate chimney flue height: D = A – (B + C).
Dimension D must be between the minimum and
maximum flue extension listed in the chart. Refer to the
illustration.

nstallation Considerations
Wolf cooktop chimney hoods are recommended for
use with Wolf induction, electric and gas cooktops and
integrated modules.
Cooktop chimney wall and island hoods are shipped
without the blower assembly. nternal, in-line and remote
blowers are available through your authorized Wolf dealer.
For local dealer information, visit the find a showroom
section of our website, wolfappliance.com.
The blower will vary in size and is dictated by the cooking
unit, the volume of air that needs to be moved and the
length of the duct run. Refer to ventilation recommenda-
tions in the Wolf design guide. These hoods have an
8" (203) round duct with vertical discharge.
IMP RTANT N TE: Use only a Wolf blower with the
cooktop chimney hood.
BACKSPLASH
Optional stainless steel backsplashes are available in
widths to match cooktop chimney wall hoods through
your authorized Wolf dealer. For local dealer information,
visit the find a showroom section of our website,
wolfappliance.com.

Electrical Requirements
Wolf cooktop chimney hoods require a separate, grounded
120 V AC, 60 Hz power supply. The service should have its
own 15 amp circuit breaker.
Locate the electrical supply within the shaded area shown
in the installation illustration for your specific model on the
following pages.
For wall hoods, allow a minimum of 12" (305) Romex®wire
from the electrical supply location on the wall for wiring
connections. For the island hood, allow a minimum of
6' (1.8) Romex®wire from the electrical supply location on
the ceiling for wiring connections.
IMP RTANT N TE: You must follow all National Electrical
Code regulations. n addition, be aware of local codes and
ordinances when installing your service.

nstall Ductwork
IMP RTANT N TE: Cooktop chimney ventilation hoods
must exhaust to the outdoors.
An 8" (203) round duct is recommended for cooktop
chimney hoods. Use only rigid metal ductwork, do not use
flex ducting.
Decide where the ductwork will run between the wall hood
and the outside. A straight, short duct run will allow the
hood to perform most efficiently. Limit the number of
elbows and transitions. The duct run should be no longer
than 50' (15 m). There is a possibility of noise issues, if a
remote blower is used with a short duct run.
Wolf recommends installing a backdraft damper in all
installations. A backdraft damper is included with the
hood. t is built into the transition from the hood to the
duct run. n cold weather installations a backdraft damper
is necessary to minimize the backflow of cold air into the
room.
Unless you are using a remote blower, a roof or wall cap
must be installed. Connect ductwork to the cap and work
back towards the hood. Use duct sealing tape to seal
joints between ductwork sections. Refer to the illustrations
on the following page.
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.
Local building codes may require the use of make-up air.
Consult your local HVAC professional for specific require-
ments in your area.
IMP RTANT N TE: Consult a qualified HVAC engineer for
specific ducting applications.
