Duct Connections
•` Blower exhaust faces towards rear wall. Connect blower exhaust to ducting with 3¼ x 10 piece. No screws are necessary.

•Do not vent into an attic or crawl space. Always vent outside.
•Seal all joints in venting system with duct tape to avoid smoke or odor in home.
•Do not use laundry wall caps. Wall cap must have minimum of 28 square inches free air space.
