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 stove's rated heat output is 5 kW. Your new Morsø stove is AS/NZS-tested for firing with
wood, and is suitable for intermittent use.
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, espe-
cially 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 igni-
tion 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 cir-
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 chop-
ped 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 st-
ove 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 em-
bers, with air at both ends.
The maximum length of fuel in the stove is 30 cm.
The maximum quantity of fuel is 2 kg/hour (max. 2 pieces of wood each time you re-
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.
