Install Ductwork
To reduce the risk of fire, use only metal ductwork.
IMPORTANT NOTE: Pro ventilation hoods must exhaust to
the outdoors except when used with the accessory recirculating kit (30" and 36" wide hoods only).
Wolf recommends that the pro wall hood be installed
30" (762) to 36" (914) above the countertop. Consult a
qualified HVAC engineer for specific ducting applications.
A 10" (254) round duct is recommended for pro ventilation
hoods. Use only 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.
Pro low-profile wall hoods allow for a horizontal or vertical
discharge. When using an in-line or external blower, an
optional 10" (254) round transition is available through
your authorized Wolf dealer. For local dealer information,
visit the find a showroom section of our website,
wolfappliance.com.
IMPORTANT NOTE: The transition included with the 500
CFM internal blower accommodates 3 1/4" (83) x 10" (254)
ductwork. An optional 3 1/4" (83) x 10" (254) to 8" (203)
round transition is available through your authorized Wolf
dealer.
Pro 24" (610) and 27" (686) deep wall hoods have a
vertical discharge. If a horizontal discharge is necessary,
an accessory horizontal discharge kit is required. Refer to
installation instructions provided with the kit. Accessory
kits are available through your authorized Wolf dealer. For
local dealer information, visit the find a showroom section
of our website, wolfappliance.com.
Always install a roof or wall cap if you are not installing a
remote blower. Connect 10" (254) round metal ductwork to
the cap and work back towards the hood. Use duct tape
to seal joints between ductwork sections.
Pro 24" (610) and 27" (686) deep wall hoods have a backdraft damper included in the transition assembly. Local
codes may require the use of an additional backdraft
damper. Contact your local HVAC professional for specific
requirements. In cold weather installations, a backdraft
damper is necessary to minimize the backflow of cold air
into the room.
Local building codes may require the use of make-up air.
Consult your local HVAC professional for specific requirements in your area.

In-Line and Remote Blowers
Locate the blower so that the length of the duct run and
number of elbows and transitions are kept to a minimum.
The duct run should be no longer than 50' (15 m). If
possible, remote blowers should be located between wall
studs or roof rafters. Avoid pipes, wires and other
ductwork. Be sure there is enough space for transitions
needed between the blower and connecting ductwork. For
best performance, locate transitions nearest the blower.
Refer to the illustrations below for overall dimensions of
Wolf in-line and remote blowers. Installation instructions
shipped with each Wolf ventilation product provide
detailed specifications. These instructions can also be

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.

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.

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
