bother anyone. We recommend 80 cm above the ridge. If the chimney does not have sufficient
draught smoke nuisances and poor combustion can occur. If the chimney draught is not sufficient
an evacuator can be mounted on the chimney. If there is too much draught, a damper can be
mounted on the chimney. Ask your dealer or your local chimney sweep if your have doubts.
4. Ventilation
Combustion air is a precondition for a good and clean combustion. In most cases there is sufficient
air in the room. However in special cases it may be necessary to provide extra air in the room
where the stove is placed. This can e.g. be done by mounting an air valve in the exterior wall of the
room. Air valves which add necessary combustion air must be kept clean.
5. Before use of the oven
It is very important that you make sure that the heat cover above the firewood compartment is
mounted in the stove; it is loose from the manufacturer and could fall down during transport. Place
the heat cover right below the door/bottom of the combustion chamber so it protects the firewood
compartment against radiant heat. The heat cover is mounted by letting the 4 pegs rest on
convection holes inside the firewood compartment.
6. Before the first lighting
The first time the stove is lit is must be done gently as all the materials need to get use to the heat.
The Senotherm varnish that the stove is painted with will harden the first couple of times the stove
is heated, and it may cause some odour nuisances. So make sure that you have proper ventilation.
7. Lighting and firing in the wood-burning stove
It is very important to heat your wood-burning stove and chimney as fast as possible in order to
create optimum draught in the chimney and achieve the best combustion. A wood-burning stove
made from sheet iron will give during lighting/cooling, this may result in creaks, that is completely
normal for the stove and should not be considered as a complaint.
1. When you light your wood-burning stove we recommend the use of kindling, i.e. thin
wooden sticks (app. 1.2 – 1.5 kg), in the bottom of the stove, laid in a criss-cross
pattern as a log house. Put 2 firelighters in the middle and light them (never use
alcohol, petrol, other flammable liquids or magazines for lighting).
