User manual BOSCH DHL 565B/03 INSTALLATION INSTRUCTIONS

[. . . ] With remote blower (DAH95 models only): 120V AC 60Hz. 15A Dedicated Branch Circuit. Caution For general residential kitchen ventilating use only. DO NOT use to exhaust hazardous or explosive materials or vapors. Caution Vent unit to the outside unless using recirculation kit. Note: If using recirculation kit, refer to instructions included with that unit. Warning To reduce the risk of fire, use only metal ductwork. [. . . ] 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 damper should be on the cold air side of the thermal break. The break should be as close as possible to where the ducting enters the heated portion of the house. Hood installation height above cooktop is the user's preference. 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. Remote blowers require a five wire installation. Measure up an additional 9" to locate the centerline of the screw holes (see Figure 4). Install toggle bolts through drywall leaving 1/4" of the bolt exposed. Install one togglebolt 11 1/2" to the left of the centerline and one togglebolt 11 1/2" to the right of the centerline. These are the only installation points for the 30" hood. See Figure 4 For the 36" hood, there are 2 additional installation points. These are also at the centerline height, but are 15 3/8" from the centerline in each direction. Place the hood by sliding the mounting holes in the hood over the bolts. Install the hood flush against the back wall. 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. [. . . ] For Remote Blower Use: See Figure 3, page 3. Remove 2 hood electrical knockouts and install 1/2" conduit connectors. Run black, white and green supply wires through 1/2" conduit to hood electrical knockout behind J box. Connect power supply wires to hood wires behind J box (white to white, black to black, green to green). [. . . ]
