6. C0MBUSTION When operating with an open fire, the Stûv 21 consumes a large amount of air. Therefore, we recommend providing an external air supply, although this is not mandatory. A sufficient air inlet must be created under the stove, at the front. When not using the air intake box with connected duct, the base of the fire must be supplied with fresh air.
