Pro Wall Hood Installation
10
Install Ductwork
IMPORTANT NOTE:
Pro ventilation hoods must exhaust to
the outdoors except when used with the accessory recir-
culating 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,

CFM internal blower accommodates 3

ductwork. An optional 3

" (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 back-
draft 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 require-
ments in your area.
To reduce the risk of fire, use only metal ductwork.
