ADDITIONAL INFORMATION

Be sure to keep fireplace dampers closed when not in use They provide an
excellent escape route for heat and humidity
On occasion, indoor moisture producing activities such as clothes drying,
cooking, showers, etc, may raise the humidity level higher than it should be,
even though the Aprilaire humidifier is not operating Telltale indications are
condensation or frost on cold surfaces such as windows, doors, walls, etc If
such condensation persists for several hours, your home should be ventilated to
dissipate the potentially damaging excess moisture
