• If multiple elbows are needed, ensure that there is a minimum of 24” of straight duct between any two elbows. • Avoid “S” or “back to back” configurations caused by adjacent elbows. • Thermal breaks, such as a short section of non-metallic duct, should be used in areas of extreme cold. • A back-draft damper at the duct outlet may also be required. • Do not use flexible metal duct. • Do not use duct work that is smaller in cross-sectional area than the recommended size duct. • Do not rely on duct tape alone to seal duct joints. Use sheet metal screws as require to support the duct weight. • The vent hood and cooking appliance(s) must be removable if service is required. • Be certain that the duct work does not interfere with floor joists or wall studs. • It is important to keep a minimum number of turns in the duct run, and to keep the run as short as possible. • Do not restrict the air flow by reducing the duct cross-sectional areas when making hard joints or squeezing through a tight area. • With concrete slab construction, “box-in” the duct work to prevent it from collapsing when the wet concrete is poured. Also allow room for electrical conduit. • Cross-drafts or air currents caused by adjacent open windows or doors, HVAC outlets, and ceiling fans reduce vent efficiency. 12 Duct Preparation IMPOR IMPORIMPORIMPORIMPORIMPORT TTTTTANT ANTANTANTANTANT • Tape all duct joints securely to prevent combustion by-products, smoke or odors from entering the home. This will also improve the efficiency of the system. • Do not exhaust more than one vent into a single duct run. • Only use ductwork constructed of materials deemed acceptable by state, municipal and local codes. Refer to the table below for recommended maximum straight lengths of duct to provide adequate performance.

WARNING WARNINGWARNINGWARNINGWARNINGWARNING • Failure to provide proper minimum clearance may result in a fire or safety hazard. • To reduce the risk of personal injury caused by reaching over a hot appliance, cabinet storage space located directly above the cooktop should be avoided. • Do not store combustible materials or items adversely affected by heat in cabinet areas above the appliance. • Follow the instructions regarding minimum safe clearances and installation location. Failure to do so may result in a fire or safety hazard. Minimum hood clearances are zero inches (0”) to the rear, sides and top of the hood. Thirty inches (30”) is the minimum distance between the bottom of the hood and any cooking surface. Maximum effective clearance from cooking surface to bottom of hood is 36” (914mm). 14 Electrical Power Supply REQUIREMENTS ! WARNING WARNINGWARNINGWARNINGWARNINGWARNING Failure to disconnect power may result in electrical shock or fire hazard! If the electric service provided does not meet the product specifications, do not proceed with the installation. Call the selling dealer or a licensed electrician. It is the owner’s responsibility to ensure that the electrical connection of this appliance is performed by a qualified electrician. The electrical installation including minimum supply wire size and grounding, must be in accordance with the latest revision of the National Electric code ANSI/NFPA and local codes and ordinances.

Installation 15 INSTALLING THE HOOD First temporarily mount a 2x4 ledger board 30” (762mm) from the finished countertop. Then, remove the filters from the hood canopy and remove the shields below the power ventilator. Secure the hood through the keyhole slots in the top of the hood and/or the slot hole in the rear of the hood. Remove the temporary support ledger.
