In a WIKING wood-burning stove, the regulation of air during lighting and re-stoking is managed automatically through the WIKING® Automatic™ device.
A heat-sensitive bimetallic spring expands or contracts depending on the temperature in the wood-burning stove. When lighting the fire, the damper will be open to ensure that the flames are supplied with the correct amount of air to get the fire started. The following quick rise in temperature will automatically cause the damper to close, thus ensuring clean and efficient combustion. When the fire starts to die out, the damper opens automatically again to allow for new firewood to be added or to let the fire die out.
