INSTRUCTIONS FOR OPERATION
When the stove is not in use you can close the dampers to avoid a
draught through the stove.
If the stove has not been used for some time, you should check the
flue passageways for potential blockages before relighting.
Chimney fire
In the event of a chimney fire, keep the stove door, the ash container,
and all dampers on the stove closed. In an emergency, call the fire
brigade.
We recommend that you get a chimney sweep to check the chimney
before using the stove again.
Continuous operation
It is important to obtain as high a temperature as possible in the
combustion chamber. This results in best possible use of the stove
and fuel, as well as achieving clean combustion. In this way you will
avoid build-up of soot on the combustion chamber lining and glass
pane. During operation, you should not see any smoke; just a movement in the air that indicates combustion is in progress.
After completing the lighting phase, you should have a good layer of
embers in the stove; you can then start operation of it proper. Add
two pieces of wood at a time: they should be about 0.6 to 0.8 kg in
weight and about 25 cm long.
NB: The wood must catch fire quickly; this is why we recommend
setting the primary airflow fully open. Operating the stove at too
low a temperature and with too little primary air can lead to gases
igniting, which can damage the stove.
When adding wood, always open the glass door carefully to prevent
smoke escaping. Never add wood while the fire is burning nicely.
Operating the stove in the spring or autumn
In the spring/autumn transition period, where there is less need
for heating, we recommend you light the stove “top down” once,
perhaps adding just two pieces of wood as above to ensure that the
combustion chamber lining burns clean again.
The function of the chimney
The chimney is the wood-burning stove’s motor; its performance
determines how well your stove will work. The draught in the
chimney creates negative pressure in the wood-burning stove. The
negative pressure draws the smoke out of the stove and takes in air
through the combustion air damper to fuel the combustion process.
Combustion air is also used for the airwash system that keeps the
window clear of soot.
The draught in the chimney is created by the difference in temperature inside and outside the chimney. The higher the difference in
temperature, the better the draught. This is why it is important that
the chimney reaches operating temperature before you reduce the
damper settings to restrict combustion in the stove (a brickwork
chimney will take longer to reach operating temperature than a steel
chimney). It is very important that the operating temperature is reached as quickly as possible on days when the draught in the chimney
is poor due to unfavourable wind and weather conditions. You need
to get a few flames going as quickly as possible. Chop the wood extra
thin; use an extra fire lighter etc.
After longer periods without use, you must check the chimney flue
for blockages.
You can connect several units to the same chimney. You should however first check the relevant regulations in this respect.
No matter how good your chimney is, it will not perform well if you
do not use it correctly. Equally, a poor chimney may well give you
acceptable results if you use it correctly.
Using your stove in various weather conditions
The way the wind affects the chimney can have a big impact on how
your stove reacts under various wind loads; you may need to adjust
the airflow to achieve good combustion. Fitting a damper in the flue
pipe may also help, as it will allow you to regulate the draught under
changing wind loads.
Fog and mist can also have a big impact on chimney draught; you
may need to use other settings for the combustion air to achieve
good combustion.
General notes.
Please note! Parts of the wood-burning stove, especially the outer
surfaces, become hot during use. Due care should be exercised.
Never empty ashes into a flammable container. Ashes can contain
glowing embers long after you finish operating the stove.
Handling fuel
Selecting wood/fuel
You can use any type of wood as fuel. However harder woods, such
as beech or ash, are generally better for heating, as they burn more
evenly and create less ash. Other woods, such as maple, birch and
spruce, are excellent alternatives.
Preparation
The best fuel is obtained where the tree has been felled and the wood
sawn and split before May 1st. Remember to cut the wood to match
the size of the combustion chamber. We recommend a diameter of
6-10 cm. The length should be about 6 cm shorter than that of the
combustion chamber to leave enough space for air to circulate. If the
diameter of the wood is greater than the above, it should be split
down its length. Wood that has been split dries faster.
Storing
You need to store the sawn and split wood in a dry place for 1-2 years
before it will be dry enough to burn. Wood dries faster if you stack
it in an airy place. Before using it, it is a good idea to store the wood
for a few days at room temperature. Remember that wood absorbs
moisture from the air during autumn and winter.
Moisture
To avoid problematic impact on the environment and to ensure optimum operating economy, the wood should be perfectly dry before it
can be used as fuel. Maximum wood moisture content should not
exceed 20%. A moisture content of 15-18% will deliver best efficiency.
An easy way of checking wood moisture content is to knock the ends
of the two pieces of wood together. If the wood is moist, the sound
will be slightly muffled.
If you use wood that is too damp, most of the heat it produces will
be used up in evaporating the water. The stove will accordingly not
increase in temperature, nor emit heat to the room as a result. This is
obviously poor economy, and it will cause soot build-up on the glass
pane, in the stove and in the chimney. Operation using moist wood
also pollutes the environment.
Understanding the terms used to designate
quantities of wood
Various terms are used to designate quantities of wood. Before you
buy wood, it makes sense to familiarise yourself with these terms.
There are various brochures, in public libraries for example, that
cover this topic.
Use of the following as fuel is illegal
Painted, pressure impregnated, or glued wood, or sea driftwood. Nor
should you ever burn chipboard, plastics, or treated paper. These
contain substances which are hazardous to human health, to the
environment, your stove, and your chimney. In short – make sure you
only use proper wood.
