When installed in a cabinet, vent system can exhaust through the front or rear of the vent box.
Front venting:
Downdraft vent is shipped with a vent collar in the front position so no modification is required. See “Complete Installation” section.
Rear venting:
NOTE: The blank panel and 10" (25.4 cm) diameter vent collar need to be removed and placed in the opposite position.
1.To remove panels, loosen the 2 hex/slotted head screws that attach the top bracket that secures the motor to the vent box enough to slide the bracket into the “Z” slots. This will move the bracket away from the top mounting lip of the blower box and allow it to tilt away from the vent box panel.
