Risk of electrical shock. This ventilation hood must be properly grounded. Electrical service for the hood must be installed by a qualified electrician in accordance with all applicable national and local electrical codes. Pro Hood Liner Installation Install Ductwork To reduce the risk of fire, use only metal ductwork. IMPORTANT NOTE: Pro ventilation hood liners must exhaust to the outdoors. Wolf recommends that the ventilation hood be installed 30" (762) to 36" (914) above the countertop. Consult a qual- ified HVAC engineer for specific ducting applications. A 10" (254) round duct is recommended for pro ventilation hood liners. Use only rigid metal ductwork, do not use flex ducting. Decide where the ductwork will run between the hood liner and the outside. Pro hood liners 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 hood liners 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.

Dimensions will vary with the width of the hood liner. Refer to the illustration and chart on page 7. 2) Using minimum 2" (51) x 4" (102) lumber, construct the wall framing flush with the wall studs and centered in the location that the hood liner will be mounted. Proper structural support is required to accommodate the weight of the hood liner. 3) Refer to the illustrations below for the location of mounting holes for pro hood liners and a cross-section view of a typical installation. Framing must be fastened together and to ceiling joists to provide enough structural strength to support the weight of the hood and internal blower, if applicable.
