•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.
