PROPER VENTILATION REQUIREMENTS6IMPORTANT INFORMATION:CAUTION:Ventilation hoods and blowers are designed for use with single wall ducting.However, some local building codes or inspectors may require double wallducting. Consult local building codes and/or local agencies before starting, toensure that hood and duct installation will meet local requirements. Hoodblower speeds should be variable to reduce noise and loss of heated or airconditioned household air when maximum ventilation is not required. For bestsmoke elimination, the lower edge of the hood should BE INSTALLED AMINIMUM OF 30" TO A MAXIMUM OF 36" ABOVE THE COOKING SURFACE. If thehood contains any combustible materials (i.e. a wood covering) it must be aminimum of 36" above the cooking surface. Due to a high volume of ventilationair, a source of outside replacement air is recommended. This is particularlyimportant for tightly sealed and insulated homes. A reputable heating andventilating contractor should be consulted.VENTILATION REQUIREMENTS:STANDARD COUNTER INSTALLATION RECOMMENDATIONSHOOD: (24" Deep x Unit Width)BLOWER: 30”/36" COOKTOPS600 CFM min. 3O" Min. clearance tonon-combustible surface,36" Min. clearance tocombustible surface – fromcooktop cooking surface18" Min. clearance tocombustible surfacefrom side of cooktopouter edge5"min. tocombustiblesurface∆ As defined in the “National Fuel Gas Code” (ANSI Z223.1, lastest edition).The horizontal surfaces of the range top (cooktop) trim must not be belowcountertop level.NOTE: See manufacture’s recommendations for ducting specifications.
