Firing The Stove - Morso 3610 Instructions And Operating Instructions

2.0 Firing the stove/Using your stove
Your stove is constructed with air supplies in three places.
One air supply leads to the combustion via a duct through  holes at the front of the partition.
A preheated secondary air supply leads to the combustion above the glass, and a preheated
tertiary air supply leads to the combustion through the numerous holes in the smoke plate
above the fire.
The secondary and tertiary air supplies are extremely simple to regulate using the handle un-
derneath the hot ash box.
The stove is fitted with a detachable handle made of stainless steel – a material that is a poor
conductor of heat. When the handle is removed, the stove is more childproof.
Morsø 3610 and 3640 are large stoves. A certain amount of expansion noise should therefore
be expected during combustion in connection with heating and cooling. The stove's rated
heat output is 9 kW. The efficieny is 73,3%. Your new Morsø stove is EN-tested and recom-
mended to be fired with wood. The stove is suitable for intermittent use.
N.B!
Wood is a material that contains a great deal of gas (approximately 75 %). The gases are re-
leased 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-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 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 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 58 cm.
The maximum quantity of fuel is 3-3.5 kg/hour (max. 4 pieces of wood each time you re-sto-
ke).
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.
