By code, a bath fan must vent moisture to the outside, ideally through a duct to the roof or, as shown here, through a gable wall. In cold climates, use insulated duct (above) to guard against condensation in the duct. Zip-tie the duct to the fan's exhaust port and to the exhaust vent, then seal the connections with foil tape.
