When remodeling a kitchen, install the hood vent before the range or cooktop so that you can reach all connections easily.
Step 1 - Connect Pipes
Connect a section of 6 or 7 inch metal ducting to the duct pipe entering the cabinet and to the hood. If these holes are too close for a turn, you may need to have a sheet metal box with nailing flanges made to your specifications.
Step 2 - Place Hood
Lift the hood into position and trace the holes for attaching the unit with the screws provided.
Step 3 - Adjust Wires
Connect the wiring in accordance with the manufacturer's instructions.
Step 4 - Connect Hood
Connect the hood collar to the duct by tightening the metal collar provided or by wrapping duct tape around both collar and duct.
