Plan The Installation; Location Preparation - Broan BDF Series Installation Instructions Manual

PLAN THE INSTALLATION

The hood should be mounted to the bottom of a standard wall
cabinet. If the hood must be mounted directly to the wall, secure
the hood to wall studs.
The hood is connected to a 110-120 V AC lighting circuit (15
amp) in the circuit breaker or fuse box.
• Ductwork can be installed vertically or horizontally.
• Duct runs should be as short as possible.
• Avoid the use of elbows.
• Use duct tape at all joints.
• Do not use duct smaller than the discharge on the hood.

2. Make cutouts for wiring and ductwork.
3. Install the ductwork so that it is flush to the range hood's
mounting surface.
