Induced draft fan designed to improve chimney efficiency by quickly evacuating smoke and preventing blockages in flues with poor draft conditions. Power and compatibility: 60 W chimney fan compatible with flue diameters of 1119.5 cm and 1319.5 cm, providing flexible installation options across different chimney sizes. Appliance and fuel compatibility: Suitable for a wide range of heating appliances including wood stoves, fireplaces, and boilers; supports residential use with fuels such as wood, gas, coal, or oil. Installation and operation: Easy to install without professional help; operates quietly and is adaptable to most chimney types to enable efficient smoke extraction. Use scenario 1: In homes with older or variabledraft chimneys, the fan helps establish reliable draft during startup and maintains steady venting for safe, clean burning. Use scenario 2: For fireplaces in cold seasons where draft can be weak, the fan maintains consistent smoke evacuation to reduce odors and backflow. Use scenario 3: Retrofit for multiappliance setups sharing a chimney (for example a wood stove and a boiler or gas appliance), where the fan helps balance exhaust flow and minimize backdraft and creosote buildup.
