Firing/Using The Stove - Morso 1400 Instructions For Installation And Use Manual

2.0 Firing/using the stove

The heat emission from the stove is adjusted with two regulation handles placed under the stove.
The primary air supply, where the air passes through the riddling grate, is regulated with the left
handle, whereas the secondary air supply, which feeds the combustion above the glass, is regu-
lated with the right handle. A third air supply consists of a continuous, preheated air stream that
feeds the combustion right above the fire. This air supply cannot be regulated.
The stove's rated heat output is 4,1 kW. The efficiency is 78,4 %.
Your new Morsø stove is EN-tested and recommended to be fired with wood. The stove is
intended 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 ig-
nited 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, 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 is less than 20%. During the 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 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
differences that may cause the stove to give off creaking sounds.
