MPORTANT NOTE:
W
olf recommends that
the Pro ventilation hood liner 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 ventilation hood
liners must exhaust to the outdoors. Always
use metal ducting. Do not use flex ducting.
Decide where the ductwork will run between
the hood liner and the outside. A straight,
short duct run will allow the hood liner 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 liner. Wolf
recommends the maximum linear duct run be
no greater than 50' (15 m). The Pro hood liner
has a vertical discharge.
IMPORTANT NOTE: There is a possibility of
noise issues, if there is a short duct run
coupled with a remote blower.
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.
W
olf Pr
o hood liners come standar
d with a
backdraft damper included in the transition
assembly. Local codes may require the use of
an additional backdraft damper
. Contact your
local HV
AC professional for specific r
equire
-
ments. In cold weather installations, a back-
draft damper is necessar
y to minimize the
backflow of cold air into the r
oom.
Local building codes may require the use of
make-up air. Consult your local HVAC profes-
sional for specific r
equirements in your area.
To reduce the risk of fire, use only metal
ductwork.
T
o r
educe the risk of fir
e and electric
shock, install this ventilation hood liner
only with a blower manufactured by
Wolf. Blower model numbers are listed
on page 14.
