The main questions and answers about stoves and heating.

During the first few heating cycles, the paint on the heating unit is hardened and may smell. This is why it is important not to exceed the maximum allowed heat output of the fireplace stove. During the first 4-5 heating cycles, ensure good air circulation in the room with the heating unit and insulate it from other rooms to prevent the smell from spreading; also, remove any small animals and birds from the area with the varnish vapors. It is also recommended you turn off water aeration in aquariums during this period. As soon as the paint is fired, the smell will disappear.

After the first heating, a smell may sometimes arise during the transition period. This is no longer caused by paint but by burning of soot, impurities and tar. Excessive amounts of tar are caused by a low chimney draft, low combustion temperature (large amount of wood compared to the amount of air intake - the stove is choking), using wood that is too wet, a clogged exchanger, incorrect connection to the heating system or incorrect operation (heating with cold exhaust pipes and a large amount of wood). Excessive condensation with tar creates creosote (tar oil), which produces an unbearable to “pungent” chemical smell during burning.

We recommend looking into the above suggestions and then properly cleaning the combustion chamber, exchanger and exhaust pipes. Start heating slowly and use small pieces of wood (which have a higher temperature and heating value); this will burn out the tar residue. Then start heating slowly with smaller amounts of wood to first heat up the exhaust pipes and prevent the creation of excessive tar.
