Never use an excessive amount of combustible. The following rule applies in this case: Better once again but not too much at a time. On the other hand you should not permanently operate your tiled stove/tiled fireplace at “low flame” otherwise the required temperature for a clean combustion is not achieved. Please study the operation manual in any case or ask your stove setter for the optimal amount of wood. When heating up, supply enough combustion air, i.e. open the air slide completely at the beginning. After approx. 20 min, please slightly reduce the air supply. The combustion air is closed completely as soon as the combustible is burnt through. In case of hot air tiled stoves/tiled fireplaces, it shall always be made sure that the hot air may escape from the tiled stove/tiled fireplace. The pipe doors and blinds shall always be open for this purpose. Store firewood for at least 2 years at a sunny place with circulation of air. The humidity shall be reduced to less than 20% in this process. Before using the wood for heating purposes, store it in the house for 2 – 3 days. The dryer the wood the better is the combustion quality and the more beautiful is the flame.
