Firing/Using The Stove - Morso 8100 Instruction 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 a constant, pre-heated air supply which cannot be adjusted, and
which comes into the combustion chamber just above the fire. This helps to burn off the last
few gasses emitted by the wood whilst it is being heated up.
The riddling grate is operated using the riddle bar, which is located behind the door.
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.
n.B!
Wood is a material that contains a great deal of gas (approximately 75 %). the gases are
released when the wood is lit and heated up. For this reason, it is important that the ga-
ses 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 gasses, resulting 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 supply) 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 content 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 greater than 10 cm should always be chopped.
the pieces of wood should be short enough to be able to lie flat over the layer of embers, with
air at both ends. the maximum length of fuel in the stove is 30 cm. the maximum quantity of
fuel is 2.5 kg/hour (max. 3 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 develop 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.
