Pro Island Hood Installation
8
Install Ductwork
IMPORTANT NOTE:
Pro ventilation hoods must exhaust to
the outdoors.
Wolf recommends that the pro island 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 island
hood and the outside. Pro island hoods have a vertical
discharge. A straight, short duct run will allow the ventila-
tion 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 island 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 require-
ments in your area.
