I N S TA L L DUCTWORK

To reduce the risk of fire, use only metal ductwork.

IMPORTANT NOTE: Wolf 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.

Wolf Pro hood liners come standard with 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 require- ments. In cold weather installations, a back- draft 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.
