5.Install the vent system according to the method needed. Use caulking to seal the exterior wall or roof opening.
6.Determine wiring knockout.
To wire through the top wiring knockout:
Measure and mark a parallel line either 10⁵⁄₈" (27.0 cm) for the 30" (76.2 cm) range hood or 11⁵⁄₈" (29.5 cm) for the
36" (91.4 cm) range hood to the right of the centerline on the cabinet ceiling. Mark a point on this line that is 4" (10.2 cm) from the back wall of the cabinet. Drill a 1¹⁄₄" (3.2 cm) diameter hole through the cabinet ceiling.

To wire through the rear wiring knockout:
Measure and mark a parallel line either 11³⁄₈" (29.8 cm) for the 30" (76.2 cm) range hood or 14³⁄₈" (36.5 cm) for the
36" (91.4 cm) range hood to the right of the centerline on the cabinet back wall. Mark a point on this line that is 8¹⁄₄" (21.0 cm) from the bottom of the cabinet. Drill a 1¹⁄₄" (3.2 cm) diameter hole through the wall.

7.Run the wiring through the wall or cabinet according to the national Electrical Code and all local codes and ordinances.
Use caulking to seal around wire opening.
NOTE: Do not turn on power until installation is complete.
8.Measure the thickness of the cabinet floor, including the filler strips, if used. If the thickness is less than ⁵⁄₈" (15.9 mm), install wood filler strips that are a minimum length of
5" (12.7 cm) onto the cabinet floor. The mounting bracket adjusts from ⁵⁄₈" (15.9 mm) to 2¹⁄₈" (54.0 mm) for the wood filler strips.
