Firing/Using The Stove; Firing The Stove - Morso 3400 Instructions For Installation And Use Manual

2.0 Firing the stove/Using your stove
The heat output of your stove is regulated by means of the 3 air inlets. The primary air supply,
i.e. the air which passes through the shaking grate, is controlled by left handle under the ash lip,
while the secondary air supply, i.e. the air supplied to the fire across the glass window, is con-
trolled by the right handle.
A third flow of air is supplied right over the fire and takes care of burning the gasses that are
freed last from the wood when it is heated. This flow may be regulated with the handle behind
the stove in the left side; however, on EN approved stoves, it must be set in the lowest position.
The stove's rated heat output is 6,5 kW. The efficiency is 74%. Your new Morsø stove is EN-tested
and recommended to be fired with wood. The stove is intended for intermittent use. The stove is
equipped with a removable handle; for safety reasons it should be removed during use, espe-
cially where children are nearby.
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 gases
are ignited quickly after stoking. If the wood just lies smouldering, especially after re-sto-
king, 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 im-
portant 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 con-
tent 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 36 cm. The maximum qu-
antity 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-re-
sistant 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.
