Bosch Appliances DAH93 Installation, General Information, Unpack Hood, Remove Knockout

Installation

General Information

1.For the most efficient air flow exhaust, use a straight run or as few elbows as possible.

2.Do not use flex ducting.

3.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.

4.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.

5.Remote blowers require a five wire installation.

6.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.

1. Unpack Hood

Pull hood from outer packaging and remove all packaging materials.

2. Remove Knockout

Remove the appropriate blower duct knockout. For horizontal discharge, remove the knockout in the back wall of the hood. For vertical discharge, remove the knockout in the top of the hood.
