We recommend that the wood burning stove is being used in warm periods in order to heat the chimney and stove and thus minimizing the risk of condensation and rust. The rust can occur if all dampers are closed. In this way, the air in the combustion chamber will stand still / be cool, which may cause condensation on the stove's surface. This is especially experienced in summerhouses where the stove is not used in periods. Therefore, remember to open the stove's damper slightly to allow the air to circulate and to create draft.
