Pro Wall Chimney Hood Installation 8
Install Ductwork
IMPORTANT NOTE: Pro ventilation hoods must exhaust to
the outdoors.
Wolf recommends that the pro wall chimney 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 rigid metal ductwork, do not use flex
ducting.
Decide where the ductwork will run between the wall
chimney hood and the outside. Pro wall chimney hoods
have a vertical discharge. A straight, short duct run will
allow the ventilation 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.
Unless you are using a remote blower, a roof or wall cap
must be installed. Connect 10" (254) round metal
ductwork to the cap and work back towards the hood.
Use duct sealing tape to seal joints between ductwork
sections.
Pro wall chimney 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 neces-
sary 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.
