Congratulations on your new stove. We
are sure that you will be happy with your
investment, especially if you follow the
advice and instructions we have put
together in these operating instructions.
The Scan-Line 40B and 50B have been
approved according to the EN 13240 /
NS 3058.
Approval means that consumers can
be sure, that the stove meets a range of
IMPORTANT
1. Make sure there is adequate provision
to sweep the chimney.
2. Make sure there is adequate ventila-
tion to the room.
3. Please note that any extraction fans
operating in the same room as the
wood-burning stove can reduce the
chimney draft – which may have an
adverse effect on stove combustion
properties. In addition, this may cause
smoke to be emitted from the stove
when the firing door is opened.
4. It must not be possible to cover any
air vents.
The floor
It is essential to ensure that the floor
surface can actually bear the weight
of the stove and a top-mounted steel
chimney, if applicable. The stove must
stand on a nonflammable surface such
as a steel floor plate or a brick or tile
floor. The size of the nonflammable sur-
face used to cover the floor area must
match national and local regulations.
The chimney connection
The chimney opening must follow na-
tional and local regulations. However,
the area of the opening should never be
less than 175 cm2, which corresponds
to a diameter of 150 mm. If a damper
is fitted in the flue gas pipe, there must
always be at least 20 cm2of free pas-
sage, even when the damper is in its
specifications and requirements inten-
ded to ensure that the materials used
are of good quality, that the stove does
not adversely affect the environment,
and hat it is economical to use.
With your new stove you should have
received the following:

INSTALLATION INSTRUCTIONS
Safety clearances
Stoves must always be installed in line
with national and, if applicable, local
regulations. It is important to abide by
local regulations regarding setting up
chimneys and connection to same.
Therefore, always consult your local
chimney sweep before installation, as
you are personally responsible for ensu-
ring that the applicable regulations have
been met.
Distance regulations
A difference applies to installation next
to flammable and non-flammable walls.
If the wall is made of non-flammable
material the stove can, in principle, be
placed flush against it. However, we re-
commend leaving a gap of at least 5 cm
to facilitate cleaning behind the stove.
The minimum distances to flammable
material are stated on the boiler plate
and are listed in the table on page 6.
Warning
A stove gets hot. (In excess of
90 degrees) Take care to en
sure that children and elderly
or infirm people cannot come
into contact with it. Combustible
materials should not be stored in the
compartment below the ashpan.

“closed” position. If local regulations
permit, two contained fireplaces can be
connected to the same chimney. Howe-
ver, you must abide by local regulations
regarding the distance between the two
connections.
Wood-burning stoves must never be
connected to chimneys that are also
linked to a gasfired heater. An efficient
stove makes high demand on chimney
properties – so always have your local
chimney sweep evaluate your chimney.
Connection to a brick chimney
Brick a thimble into the chimney and
seat the flue gas pipe in this. The
thimble and flue gas pipe must not
penetrate the chimney opening itself,
but must be flush with the inside of the
chimney duct. Joins between brickwork,
the thimble and flue gas pipe must be
sealed with fireproof material and/or
beading.
Connection to a steel chimney
When fitting a connection from a top-
output stove directly to a steel chimney,
we recommend fitting the chimney tube
inside the flue gas spigot so that any
soot and condensation drops into the
stove itself rather than collecting on
the exterior surface of the stove. For
connections to chimneys that are run
through ceilings, all national and local
regulations regarding distance to flam-
mable material must be followed. It is
important that the chimney is fitted with
roof support so that the top panel of the
stove is not required to bear the entire
weight of the chimney (excessive weight
may damage the stove).
Draft conditions
Poor draft may result in smoke being
emitted from the stove when the door
is opened. The minimum chimney draft
to ensure satisfactory combustion in
stoves of this kind is 11 PA. However,
there will still be a risk of smoke emis-
sion if the firing door is opened during
powerful firing. The flue gas temperature
at nominal output is 246°C when expel-
led to an exterior temperature of 20°C.
The flue gas mass flow is 4,7 g/sec. The
chimney draft is generated by the diffe-
rence between the high temperature of
the chimney and the low temperature of
the fresh air. The length and insulation
of the chimney, wind and weather con-
ditions also have an effect on the ability
of the chimney to generate appropriate
under-pressure.
If the stove has not been used in a
while, check that the chimney and stove
are not blocked with soot, bird nests,
etc., before using it.
Reduced draft can occur when:
•The difference in temperature is too
small - due to insufficient chimney
insulation, for example.
•The outdoor temperature is too high
in summer, for example.
•No wind is blowing.
•The chimney is too low and shelte-
red.
•The chimney contains false air.
•The chimney and flue gas pipe are
blocked.
•The house is too airtight (i.e. when
there is an insufficient supply of
fresh air).
•Poor smoke extraction (poor draft
conditions) due to a cold chimney
or bad weather conditions can be
compensated for by increasing the
airflow into the stove.
Good draft occurs when:
•The difference in temperature bet-
ween the chimney and outdoor air
is high.
•The weather is fine.
•The wind is blowing strongly.
•The chimney is of the correct height:
at least 4.00 m above the stove and
free of the roof ridge.

Chimney fires
In the event of a chimney fire – which
often results from incorrect operation or
protracted firing with moist wood – clo-
se the door and shut off the secondary/
start-up air supply to smother the fire.
Call the fire department.
Lighting and combustion
To open the flow of secondary air, use
the operating handle at the front of the
stove. The secondary airflow is complet-
ely open when the handle is to the left
side position, fig. 1.
Shut off the secondary airflow gradually
by moving the handle to the right. The
supply is completely shut off when the
handle is to the right side position, fig. 2.

First firing
The stove paint is fully cured from the
factory, but a minor unpleasant odour
could still arise.
Fuel
Your new stove is EN approved for
firing with wood fuel. You must there-
fore only burn clean, dry wood in your
stove. Never use your stove to burn
drifwood, as this may contain a lot of
salt which can damage both the stove
and the chimney. Similarly, you must
not fire your stove with refuse, painted
wood, pressure-impregnated wood or
chipboard, as these materials can emit
poisonous fumes and smoke. Correct
firing using well seasoned wood provi-
des optimal heat output and maximum
economy. At the same time, correct
firing prevents environmental damage in
the form of smoke and emmissions and
also reduces the risk of chimney fires. If
the wood is wet and inadequately sea-
soned, a large proportion of the energy
in the fuel will be used to vaporise the
water, and this will all disappear up the
chimney. Thus it is important to use dry,
well seasoned wood, i.e. wood with a
moisture content of no more than 18%.
This is achieved by storing the wood for
1–2 years before use. Pieces of firewood
with a diameter of more than 10 cm
should be split before storing. The pie-
ces of firewood should be of an appro-
priate length (approx. 25–30 cm) so that
they can lie flat on the bed of embers. If
you store your wood outdoors, it is best
to cover it.

ely open when the handle is to the left
side position, fig. 1.
Shut off the secondary airflow gradually
by moving the handle to the right. The
supply is completely shut off when the
handle is to the right side position, fig. 2.
Lighting the stove
Place two pieces of wood on the bot-
tom. Stack kindling on top in layers
with air between. Setting fire starter
(bag, brick, paraffin) on the top, now
you are ready to light the fuel. The
flames must work from the top down.
The use of lighter fluid, oils
or any liquid fuels is strictly
forbidden from use in a wood
stove.
Fully open the combustion air and
leave the door ajar (about 1 cm open).
Once the fire is established and the
chimney is hot (after about 3-5 mi-
nutes) closed door and regulate the
air into operating position. We re-
commend, all of the first fuel is burned
with the combustion air fully open in
the operating position. This ensures
the stove and chimney are thoroughly
heated.
Startup/Lighting
Scan the code and select a
language.
Refiring
You should normally refire the stove
while there is still a good layer of
embers. Distribute the embers across
the bottom grate, place pieces of fuel
(max. 2 kg) on the embers in a single
layer perpendicular to the firing opening.
Close the firing door and fully open the
start-up mechanism. The wood will then
ignite very quickly – i.e. in 30 seconds
or 1 minute. When the wood is burning
with a steady flame, close the start-up
mechanism. Then adjust the secondary
airflow to the level required. For nomi-
nal operation (6,1 kW), the secondary
air supply should be 38% open. When
firing, take care not to place the pieces
of fuel too close-ly together, as this will
result in poor combustion and insuffi-
cient exploitation of the fuel.
Reduced burning
The stove is well-suited to intermittent
use. If you wish to operate the stove
with reduced out-put, simply insert
smaller volumes of wood at each firing,
and apply a lower airflow. However,
remember that the secondary combu-
stion air supply must never be shut off
completely during firing. It is important
to keep a good bed of embers. Gentle
heat is released when the fire settles
- i.e. when the wood no longer genera-
tes flames and has been converted to
glowing embers.
Optimal firing
To achieve optimal firing and the highest
possible effect, it is important to make
sure that the air supply is used correctly.
As a general rule, the secondary air is to
be used to control the fire to ignite the
flue gases. This produces a high effect
and keeps the glass panel completely
clear of soot as the secondary air “wa-
shes” down over it. Please note that the
stove will, naturally, produce soot if both
the start-up mechanism and secondary
air intakes are closed completely. This
will prevent oxygen from being drawn
into the stove, and the viewing window
and other parts will become covered
with soot. If this situation is combined
with firing with wet wood, the build-up

6
of soot can become so thick and sticky
that the sealing rope can, for example,
become detached when the door is
opened the next day.
Risk of explosion
After you add new fuel, it is
very important that you do
not leave the stove unatten
ded until the wood is burning
constantly. This will normally occur
within 30 to 60 seconds.

MAINTENANCE
The surface of the stove has been trea-
ted with heat-resistant paint.
The stove should be cleaned with a
damp cloth. Any damage to the surface
cleaning the chimney, soot and other
deposits may come to fall on the smoke
plate. In cases where the wood burns
too quickly, this may be due to exces-
sive chimney draught. You should also
check to make sure that the door seal
and ashpan seal is intact and correctly
fitting.
If the stove it generating too little heat,
this may be because you are firing with
wet wood. In this case, much of the
heating energy is used to dry the wood,
resulting in poor heating economics and
an increased risk of soot deposits in the
chimney.
OPERATIONAL PROBLEMS
Stove data table in accordance with EN 13240 testing.
The chimney must be swept at least
once a year, we recommend the use of
a NACS (national association of chim-
ney sweeps) registered chimney sweep.
In the event of smoke or malodorous
fumes being produced, you must first
check to see whether the chimney is
blocked. The chimney must, of course,
always provide the minimum draught
necessary to ensure that it is possible to
regulate the fire. Please note, however,
that chimney draft is dependent on the
weather conditions. In high winds, the
draft can become so powerful that it
may be necessary to fit a damper in the
flue gas pipe to regulate the draft. When
A risk of explosion can possibly arise if
too much wood is placed in the stove.
This may result in the production of
large volumes of gas, and this gas can
explode if the intake of primary and
secondary air is insufficient.
It is an advantage always to leave some
ash lying in the bottom of the combstion
chamber.
Take care when emptying the ash
pan, as cinders can continue to burn
in the ash for long periods of time.
in the form of chips or scratches can be
repaired using touch-up paint, which is
available in spray cans.
