This unit is approved for use with all residential appliances. Note: The Bosch ventilation hood referred to throughout this manual is manufactured by BSH Home Appliances Corporation. 2 Installation General Information 1. For the most efficient air flow exhaust, use a straight run or as few elbows as possible. COLD WEATHER installations should have an additional backdraft damper installed to minimize backward cold air flow and a nonmetallic thermal break to minimize conduction of outside temperatures as part of the ductwork. The break should be as close as possible to where the ducting enters the heated portion of the house. The lower the hood above the cooktop, the more efficient the capturing of cooking odors, grease, and smoke. This hood has been approved for installations as low as 24 inches and as high as 36" above the cooktop. The lower height may be inconvenient for tall people and large cooking vessels. Consequently, Bosch recommends the hood be installed 30"-36" above the countertop. Place the hood by sliding the mounting holes in the hood over the bolts. Identify the centerline on the mounting surface (underside of cabinet). Place the hood and install the drywall screws through the mounting holes. Insert 3 drywall screws 11 1/2" off the centerline in both directions at the following depths: 1. The 36" hood also requires 3 additional screws, at the same depths, on each side (total of 6).
