Firing/Using The Stove - Morso S12 series Instructions For Installation And Use Manual

2.0 Firing/using the stove

Your stove is constructed with air inlets in two places.
Pre-heated, fast-moving combustion air is added to the fire above the glass window, and is
regulated using the handle above the door. The combustion air is let in when the handle is
pushed to the right, and shut off when the handle is pushed to the left.
Another air inlet provides constant, pre-heated air supply which cannot be adjusted, and which
comes into the combustion chamber just above the fire. This helps burn off the last few gasses
emitted by the wood while it is being heated.
The stove's rated heat output is 6 kW.
Your new Morsø stove is EN-tested for firing with wood, and is suitable for intermittent use.
nB!
Wood is a material that contains a great deal of gas (approx. 75%). The gases are released
when the wood is lit and heated. For this reason, it is important that these gases are ignited
quickly after stoking. If the wood just lies smouldering, especially after re-stoking, a lot of
smoke is created which, in the worst case, may cause an explosive ignition of the gases, resul-
ting in damage to the stove.
In order to ignite the gases that are released from the wood, and to keep clear, lasting flames
during the combustion process, it is important to let in the required quantity of oxygen (air sup-
ply) at all times. The setting of the air supply, the method of ignition and the lighting intervals
depend on the draught in the chimney, the wind and weather, the amount of heat required, the
fuel, etc. This means that it may take some time before you get to know the correct functioning
of the stove under any given circumstances.
Although you can fire your Morsø stove with almost all kinds of wood, you should not fire with
wet wood, or unseasoned wood. Wood ought to be stored under a roof for at least 1 year, and
preferably 2 years, with free access to wind. Wood should be chopped as soon as possible after
felling if it is to dry quickly. The wood can be used once the moisture is less than 20%. During
the En test, all stoves are tested with wood with a moisture content of (16 ± 4)%.
never use driftwood as it usually has a high salt content, which damages both the stove and the
chimney. Impregnated and painted wood and chipboard emit poisonous smoke and fumes so
they should not be used as fuel either
Please note that liquid fuel may not be used in the stove.
Pieces of wood with a diameter exceeding 10 cm should always be chopped.
The pieces of wood should be short enough to be able to lie flat over the layers of embers, with
air at both ends. The maximum length of fuel in the stove is 30 cm. The maximum quantity of
fuel is approx. 2 kg/hour (max. 2 pieces of wood each time you re-stoke).
The first few times you light the stove, the fire should be moderate so that the heat-resistant
paint can harden before firing more vigorously. During the hardening phase, the paint may de-
velop obnoxious smoke and smell the first time it is lit, which is very normal. Make sure that
the room is well ventilated during this period.
When heating up or cooling down, the material is exposed to major temperature diffe-
rences that may cause the stove to give off creaking sounds.
