[. . . ] wARNING TO REDUCE THE RISK OF FIRE , USE ONLY METAL DUCT WORK. Install this hood in accordance with all requirements speci ed. Always leave safety grills and lters in place. Without these components, operating blowers could catch onto hair, ngers and loose clothing. [. . . ] The break should be as close as possible to where the ducting enters the heated portion of the house. Make up air: Local building codes may require the use of Make-Up Air Systems when using Ducted Ventilation Systems greater than specified CFM of air movement. the specified CFM varies from locale to locale. Consult your HVAC professional for specific requirements in your area. Typical installation The height from the countertop to the bottom of the hood is 24" to 30". These hoods are not recommended to be used over indoor grills. Choose vent options The hood is designed ready to be used for vertical discharge as shown below. Install a 1/2" conduit from the service panel long enough to reach the hood once it is installed. Power supply must be rated for 120 V AC, 60 Hz. For safety reasons, ducting should vent directly outdoors (not into an attic, underneath the house, into the garage or into any enclosed space). Keep duct runs as short and straight as possible. duct fittings (elbows and transitions) reduce air flow efficiency. Back to back elbows and , , S" turns give very poor delivery and are not recommended. A short straight length of duct at the inlet of the remote blower gives the best delivery. Transition to duct from the integral blower or remote duct transition as close to the downdraft as is pos-sible. 6" round duct The use of flexible metal round duct should only be used when no other duct fitting exists. Limit use to short lengths and do not crush when making corners. Prepare duct and conduit cut outs, see Fig. Before installing remove the knock-out plate that close the air outlet on the top if is desired to use the range hood for vertical discharge OR the rear outlet if is desired to use the range hood for horizontal discharge. NOTICE Once the Knock out plate has been removed, this cannot be reinstalled anymore close the air outlet (see also Figure 5). Remove and keep the 4 screws (2 per side) that x blower on top of the hood and release it from keyholes. Fix the blower on the rear side with the same 4 screws (see step b). [. . . ] Note: If possible fix the hood on the wall at 4 additional point (2 on upper side, 2 on lower side). From the inside of the cabinet attach the transition on upper outlet (vertical discharge see also , , Assembly of the 8" Transition" on previous pages) Screw for cabinet bottom installation Adjusting screw Fix Duct to transition and seal with tape. Wiring the HOOD: WARNING Electrical Shock Hazard Turn o power at the service panel before wiring this unit. Failure to do so can result in death or electrical shock. [. . . ]
