Installation Considerations
IMPORTANT INSTRUCTIONS
TO REDUCE THE RISK OF FIRE, ELECTRIC
SHOCK OR INJURY, OBSERVE THE FOLLOWING:
• Installation work and electrical wiring must be
done by qualified person(s) in accordance with all
applicable codes and standards, including fire-rated
construction.
• Two installers are recommended due to the size and
weight of the pro hood liner.
• Install the pro hood liner only with a blower manufac-
tured by Wolf.
4
Installation Considerations
Wolf pro hood liners are recommended for use with all
Wolf cooking appliances.
• Proper installation is the responsibility of the installer.
Product failure due to improper installation is not
covered under the Wolf warranty. Refer to the Wolf pro
ventilation hoods use & care guide for warranty details,
or visit the contact & support section of our website,
wolfappliance.com.
• Warranty service must be performed by Wolf factory
certified service. Wolf is not responsible for service
required to correct a faulty installation.
• When cutting or drilling into wall or ceiling, do not
damage electrical wiring and other hidden utilities.
• Ducted fans must always be vented to the outdoors.
To reduce the risk of fire and properly exhaust air,
be certain to duct air outside. Do not vent exhaust
air into spaces within walls or ceilings or into attics,
crawl spaces or garages.
DECORATIVE HOODS
The bottom edge of the decorative hood can not extend
below the hood liner. The bottom 3/4" (19) of the hood liner
is stainless steel. The remaining reveal is galvanized metal.
Verify the decorative hood does not extend beyond 3/4"
(19) to ensure the most visually appealing installation.
BLOWER ASSEMBLIES
Wolf pro hood liners are shipped without a blower
assembly. Internal, 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.
Blower size is dependant on the size of the cooking
surface, volume of air being moved and length of the duct
run. Refer to ventilation recommendations in the Wolf
design guide.
In-line and remote blowers require a Romex® (not
provided) from the blower to the ventilation hood.
For blower installation, refer to specific instructions
provided with each blower. Additional information can also
be found on our website, wolfappliance.com.

Electrical Requirements
The illustration below provides dimensions critical for
proper installation of the pro hood liner. Dimension A in the
illustration will vary with the width of the hood liner. Refer
to the chart below.
Wolf pro hood liners 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 on the
previous page.
In-line and remote blowers require a Romex® (not
provided) from the blower to the ventilation hood.

Install Ductwork
PRO HOOD LINERS
To reduce the risk of fire, use only metal ductwork.
10" (254) round, rigid metal duct is recommended for pro
hood liners.
A straight, short run is most effective and will ensure
proper operation. For best results, duct run should not
exceed 50' (15 m). For runs exceeding 50' (15 m), a higher
CFM blower may be required to maintain proper air flow
and performance. A remote blower installed on a short
duct run may increase the potential for noise.
Internal and in-line blowers require a roof or wall cap (not
provided). Connect ductwork to the cap and work back
towards the hood liner. Use sheet metal screws and
aluminum tape or high temperature duct tape to seal joints
between ductwork sections.
All pro hood liners include a backdraft damper in the transition assembly. Local codes may require the use of an
additional backdraft and/or make-up air damper. Contact
your local HVAC professional for specific requirements.
Backdraft and make-up air dampers are available through
your authorized Wolf dealer. For local dealer information,
visit the find a showroom section of our website,
wolfappliance.com.

size of the surface element.
TO REDUCE THE RISK OF INJURY TO PERSONS IN THE EVENT
OF A RANGE TOP GREASE FIRE, OBSERVE THE FOLLOWING:*
1. SMOTHER FLAMES with a close-fitting lid, cookie sheet, or
metal tray, then turn off the burner. BE CAREFUL TO PREVENT
BURNS. If the flames do not go out immediately, EVACUATE AND
CALL THE FIRE DEPARTMENT.
2. NEVER PICK UP A FLAMING PAN - You may be burned.
3. DO NOT USE WATER, including wet dishcloths or towels - violent
steam explosion will result.
4. Use an extinguisher ONLY if:
A. You know you have a Class ABC extinguisher and you already
know how to operate it.
B. The fire is small and contained in the area where it started.
C. The fire department is being called.
D. You can fight the fire with your back to an exit.
* Based on “Kitchen Fire Safety Tips” published by NFPA.
CAUTION
!
1. For general ventilating use only. Do not use to exhaust hazardous
or explosive materials and vapors.
2. To avoid motor bearing damage and noisy and/or unbalanced
impellers, keep drywall spray, construction dust, etc. off power
unit.
3. If ventilator is installed in an unconditioned space (such
as an attic): Surround the ventilator with thermal insulation - to
minimize possible condensation.
4. Please read specification label on product for further information
and requirements.

WARNING
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY
TO PERSONS, OBSERVE THE FOLLOWING:
1. Use this unit only in the manner intended by the manufacturer. If
you have questions, contact the manufacturer or your distributor.
2. Before servicing or cleaning unit, switch power off at service panel
and lock the service disconnecting means to prevent power from
being switched on accidentally. When the service disconnecting
means cannot be locked, securely fasten a prominent warning
device, such as a tag, to the service panel.
3. Installation work and electrical wiring must be done by a qualified
person(s) in accordance with all applicable codes and standards,
including fire-rated construction codes and standards.
4. Sufficient air is needed for proper combustion and exhausting of
gases through the flue (chimney) of fuel burning equipment to prevent backdrafting. Follow the heating equipment manufacturer’s
guideline and safety standards such as those published by the
National Fire Protection Association (NFPA), and the American
Society for Heating, Refrigeration and Air Conditioning Engineers
(ASHRAE), and the local code authorities.
5. When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.
6. Ducted fans must always be vented to the outdoors.
7. To reduce the risk of fire, use only steel ductwork.
8. If this unit is to be installed over a tub or shower, it must be marked
as appropriate for the application and be connected to a GFCI
(Ground Fault Interrupter) - protected branch circuit.
9. Never place a switch where it can be reached from a tub or
shower.
10. This unit must be grounded.
TO REDUCE THE RISK OF A RANGE TOP GREASE FIRE:
1. Never leave surface units unattended at high settings. Boilovers
cause smoking and greasy spillovers that may ignite. Heat oils
slowly on low or medium settings.
2. Always turn hood ON when cooking at high heat or when flambeing food (i.e. Crepes Suzette, Cherries Jubilee, Peppercorn Beef
Flambe’).
3. Clean ventilating fans frequently. Grease should not be allowed
to accumulate on fan or filter.
4. Use proper pan size. Always use cookware appropriate for the
size of the surface element.
TO REDUCE THE RISK OF INJURY TO PERSONS IN THE EVENT
OF A RANGE TOP GREASE FIRE, OBSERVE THE FOLLOWING:*
1. SMOTHER FLAMES with a close-fitting lid, cookie sheet, or
metal tray, then turn off the burner. BE CAREFUL TO PREVENT
BURNS. If the flames do not go out immediately, EVACUATE AND
CALL THE FIRE DEPARTMENT.
2. NEVER PICK UP A FLAMING PAN - You may be burned.
3. DO NOT USE WATER, including wet dishcloths or towels - violent
steam explosion will result.
4. Use an extinguisher ONLY if:
A. You know you have a Class ABC extinguisher and you already
know how to operate it.
B. The fire is small and contained in the area where it started.
C. The fire department is being called.
D. You can fight the fire with your back to an exit.
* Based on “Kitchen Fire Safety Tips” published by NFPA.
CAUTION
!
1. For general ventilating use only. Do not use to exhaust hazardous
or explosive materials and vapors.
2. To avoid motor bearing damage and noisy and/or unbalanced
impellers, keep drywall spray, construction dust, etc. off power
unit.
3. If ventilator is installed in an unconditioned space (such
as an attic): Surround the ventilator with thermal insulation - to
minimize possible condensation.
4. Please read specification label on product for further information
and requirements.

WARNING
CAUTION
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR
INJURY TO PERSONS, OBSERVE THE FOLLOWING:
1. Use this unit only in the manner intended by the manufacturer.
If you have questions, contact the manufacturer or your distributor.
2. Before servicing or cleaning unit, switch power off at service
panel and lock the service disconnecting means to prevent
power from being switched on accidentally. When the service
disconnecting means cannot be locked, securely fasten a
prominent warning device, such as a tag, to the service panel.
3.Installation work and electrical wiring must be done by a
qualified person(s) in accordance with all applicable codes
and standards, including fire-rated construction codes and
standards.
4. Sufficient air is needed for proper combustion and exhausting
of gases through the flue (chimney) of fuel burning equipment to prevent backdrafting. Follow the heating equipment
manufacturer’s guidelines and safety standards such as those
published by the National Fire Protection Association (NFPA),
and the American Society for Heating, Refrigeration and Air
Conditioning Engineers (ASHRAE), and the local code authorities.
5.When cutting or drilling into wall or ceiling, do not damage

7. Do not use this unit with an additional speed control device.
8. To reduce the risk of fire, use only steel ductwork.
9. This unit must be grounded.
TO REDUCE THE RISK OF A COOKTOP GREASE FIRE:
1. Never leave surface units unattended at high settings. Boilovers
cause smoking and greasy spillovers that may ignite. Heat oils
slowly on low or medium settings.
2.Always turn hood ON when cooking at high heat or when
cooking flaming foods.
3. Clean ventilating fans frequently. Grease should not be allowed
to accumulate on fan or filter.
4. Use proper pan size. Always use cookware appropriate for the
size of the surface element.
TO REDUCE THE RISK OF INJURY TO PERSONS IN THE
EVENT OF A COOKTOP GREASE FIRE, OBSERVE THE
FOLLOWING:*
1. SMOTHER FLAMES with a close-fitting lid, cookie sheet, or
metal tray, then turn off the burner. BE CAREFUL TO PREVENT
BURNS. If the flames do not go out immediately, EVACUATE
AND CALL THE FIRE DEPARTMENT.
2. NEVER PICK UP A FLAMING PAN - You may be burned.
3.DO NOT USE WATER, including wet dishcloths or towels violent steam explosion will result.
4. Use an extinguisher ONLY if:
A.You know you have a Class ABC extinguisher and you
already know how to operate it.
B. The fire is small and contained in the area where it started.
C.The fire department is being called.
D. You can fight the fire with your back to an exit.
* Based on “Kitchen Fire Safety Tips” published by NFPA.
1. For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors.
2. To avoid motor bearing damage and noisy and/or unbalanced
impellers, keep drywall spray, construction dust, etc. off power
unit.
3. Your ventilator motor has a thermal overload which will automatically shut off the motor if it becomes overheated. The motor
will restart when it cools down. If the motor continues to shut
off and restart, have the hood serviced.
4. Please read specification label on product for further information and requirements.
