STEP 1: INSTALL DUCTWORK
IMPORTANT NOTE:
Wolf recommends that
the Pro wall ventilation hood be installed
30" (762) to 36" (914) above the countertop.
IMPORTANT NOTE:
Consult a qualified HVAC
Engineer for specific ducting applications.
IMPORTANT NOTE:
All Wolf Pro 27" (686)
deep wall hoods must exhaust to the outdoors.
Always use metal ducting. Do not use flex
ducting.
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). The 27" (686) deep wall hood
is vertical discharge only.
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 sealing tape
on joints between ductwork sections.
IMPORTANT NOTE:
Do not use ducting
smaller than 10" (254) round.
Pro wall hoods come standard with a backdraft
damper included in the transition assembly. 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 profes-
sional for specific requirements in your area.
To reduce the risk of fire, use only metal
ductwork.
Ducting options for 27" (686) deep wall hoods
To reduce the risk of fire and electric
shock, install this ventilation hood only
with a blower manufactured by Wolf.
