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

IMPORTANT NOTE: Wolf recommends that the Pro wall ventilation hood 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 Pro 27" (686) deep wall 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). The 27" (686) deep wall hood is vertical discharge only.

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.

IMPORTANT NOTE: Do not use ducting smaller than 10" (254) round.

Pro wall hoods come standard with a backdraft damper included in the transition assembly. 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 profes- sional for specific requirements in your area.
