Plan the location
Determine the exact location of the vent hood.
• Use a plumb bob to check location to be sure countertop/
cooktop location below the hood will align exactly.
• The hood should project forward 1-1/2" beyond the front
edge of the cooking appliance. See illustration.
• Observe the recommended space (30") between the cooking
surface and bottom of hood.
