I N S TA L L DUCTWORK
To reduce the risk of fire, use only metal ductwork.
IMPORTANT NOTE: Wolf recommends that the Pro wall chimney hood be installed 30" (762) to 36" (914) above the countertop.
IMPORTANT NOTE: All Pro wall chimney 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). Pro wall chimney hoods have 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 wall chimney hoods come standard with a backdraft damper included in the transi- tion 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.
