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 550 inset stove has
been approved according to the EN
13229, DIN+, and 15a B-VG.
Approval means that consumers can
be sure, that the stove meets a range
of specifications and requirements in-
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
A non-flammable floor surface (e.g.
steel, tile, brick), must extend from the
front of the fireplace for a minimum of
30 cm.
The chimney connection
The chimney opening must follow national 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 cm2 of
free passage, even when the damper is
in its “closed” position. If local regulations permit, two contained fireplaces
can be connected to the same chimney. However, you must abide by local
regulations regarding the distance between the two connections.
tended 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:
a. Operating instructions
b. Guarantee slip
c. A stove glove
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 ensuring that the applicable regulations
have been met.
Distance regulations
A difference applies to installation next
to flammable and non-flammable walls.
Warning
A stove gets hot. (In excess of
90 degrees) Take care to ensure that children cannot
come into contact with it.
IMPORTANT
1. Make sure there is adequate provision to sweep the chimney.
2. Make sure there is adequate ventilation to the room.
3. Please note that any extraction fans
operating in the same room as the
wood-burning stove can reduce the

The stove 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 topoutput 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
flammable 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 12 PA. However,
there will still be a risk of smoke emission if the firing door is opened during
powerful firing. The flue gas tempera-
ture at nominal output is 290°C when
expelled to an exterior temperature of
20°C. The flue gas mass flow is 6 g/
sec. The chimney draft is generated by
the difference between the high temperature of the chimney and the low
temperature of the fresh air. The length
and insula-tion of the chimney, wind
and weather conditions 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 sheltered.
- 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
between the chimney and outdoor
air is high.
- The weather is fine.
- The wind is blowing strongly.
- Th
e chimney is of the correct height:
at least 4.00 m above the stove and
free of the roof ridge.

Combustion air flow
The insert stove is approved as a
room air-dependent insert stove in
accordance with EN 13229. All the
combustion air flow in the inset stove
comes from the room in which it is
fitted. However, by connecting a
sealed air inlet to the insert stove’s
air intake connectors, the stove can
be supplied with external combustion
air flow. In this respect, the following
requirements must be met:
• Only approved materials may be
used from the ventilation unit to
the air inlet vent.
• The air inlet vent must be fitted
correctly and insulated to prevent
formation of condensate. The
cross section of the vent and grille
must be at least 78 cm².
• If the vent leads out into the open
air, please note that the grille
must be fitted with suitable wind
protection. There must be no risk
that the grille can get clogged by
leaves, etc.

Assembling the convection
box
1. The flue collar is always put in the
combustion chamber. The flue
collar is fitted on the chimney pipe
where the inset stove later will be
installed. This is done to ease the
connection at the end.
2. Assemble the convention box.
It has to be adjusted exactly to
horizontal level by means of the
adjustable bolts at the bottom
(this should be done before the
inset stove is put in).
3. Before the convection box is
installed you have to make up
your mind if the inset stove should
pass on heat to some stone
mass (thermal mass stove effect).
Should you want this effect the
flange above the convection box
should not the fitted. On the other
hand should you want direct convection heat through the distance
between the convection box and
inset stove the flange has to be
fitted, so that the heat does not
disappear into the stone mass.

Installing the inset stove into the convection box
1. Remove the magnet fittings from
the convection box to ease the
installation.
2. Remove the vermiculite bricks
from the combustions chamber.
3. Lift the stove and put it into the
convection box.
4. The stove has to fall into place in
the grooves at the bottom of the
convection box so that the distance to the sides of convections
box is equal.
5. Adjust the stove back and forward
in the grooves so that the door is
in line with the front frame, which
will be fitted at the end.
6. When the stove is fitted correctly
it has to be fastened with the
screws at the back of the combustion chamber. The top screw has
to go through both the combustions chamber and the convection
box. The bottom screw has to be
screwed against the convection
box as back pressure.
7. Insert the vermiculite bricks in the
combustion chamber again.
8. Fit both magnet fittings again. It is
important that they are in level, so
that the magnet can get a proper
grip.
9. To fit the front frame the door
must be fully open. Loosen the
two screws which the frame
should be hung upon and hook
the frame on. Adjust the frame so
that it is in line with the stove and
fasten the screws again.

INSTRUCTIONS FOR USE
First firing
The stove has been treated with a
heat-resistant coating which har
dens
at a temperature of approximately
250
ºC. This hardening process causes the
production of smoke and malodorous
fumes, so the room must be very well
ventilated.
During the first firing, which should be
carried out using approximatly 1,0 kg.
of wood, the stoking door must be left
slightly open and must not be closed
until the stove is cold. This is to prevent
the sealing rope sticking to the stove.
Fuel
Your new stove is EN approved for firing
with wood fuel. You must therefore
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 provides 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 seasoned, 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 20%. This is achieved by
storing the wood for 1–2 years before
use. Pieces of firewood with a diame-
ter of more than 10 cm should be split
before storing. The pieces of firewood
should be of an appropriate length (approx. 25 cm) so that they can lie flat
on the bed of embers. If you store your
wood outdoors, it is best to cover it.

It is advised not to use very oil-containing woods like teak tree and mahogany, as this can cause damage
to the glass.
Heating value in wood
You have to use about 2.4 kg normal
wood to replace one litre of heating oil.
All woods have almost the same heating value per kg, which is about 5.27
kW/hour for absolute dry wood. Wood
with a moistness of 18% has a efficiency of about 4.18 kW/hour per kg, and
one litre heating oil contains about 10
kW/hour.

CO2 release
At combustion 1000 litres of heating
oil forms 3.171 tons CO2. As wood is
a CO2 neutral heat/ energy source, you
save the environment about 1.3 kg CO2
every time you have used 1 kg normal
wood.
Chimney fires
In the event of a chimney fire – which
often results from incorrect operation
or protracted firing with moist wood
– close the door and shut off the secondary/start-up air supply to smother
the fire. Call the fire department.
Regulating the airflow
Secondary airflow is regulated using
the operating handle below the glass
door.
The secondary airflow is fully open
when the operating handle is in the
right position, and fully closed when
positioned to the left.
Lighting
To ignite the fuel, use fire lighters, small
paraffin ignition bags or small pieces of
wood placed on the bottom grate. Place
larger pieces of wood on top of this kindling material, at right angles to the firing,
doors. Completely open the secondary
air supply and leave the firing door ajar
– i.e. approx. 1 cm open. Once the fire
has taken a good hold of the fuel and the
chimney has heated up (after about 10
min) close the firing door. We recommend
that you burn the entire first firing with the
secondary air supply fully open to make
sure that the chimney is thoroughly heated.
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.
2,5 kg) on the embers in a single layer
perpendicular to the firing opening.
Close the firing door.The wood will
then ignite within 30 to 60 seconds.
When the flames are steady, adjust the
secondary airflow to the level required.
Nominal operation (5 kW) will be achieved when the secondary airflow is fully
open.
When firing, take care not to place the
pieces of fuel too closely together, as
this will result in poor combustion and
insufficient exploitation of the fuel.

Start-up airflow
To open the start-up airflow for the
stove, pull the handle on the start-up
mechanism as far to the left-hand side
of the stove (as seen from the front)
as possible. See fig. 2. To close the
start-up airflow for the stove, push the
handle on the start-up mechanism as
far to the right-hand side of the stove
(as seen from the front) as possible.

Please note that the start-up
mechanism must not remain open during
normal operation of the stove,
as
this may lead to overheating. It must only
be
used until the fuel is burning with a
steady
flame.
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, re-
member that the secondary
combustion
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 generates 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 “washes” down over it.
Please note that the stove will, naturally, produce soot if the 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 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 unattended
until the wood is burning con stantly. This will normally oc
cur within 30 to 60 seconds.
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.
Be careful when emptying the ashes.
Hot embers can remain in the ash
for a long time.

OPERATIONAL PROBLEMS
The chimney must be swept at least
once a year, we recommend the use of
a NACS (national assoc
iation of chimney
sweeps) registered chimney sweep. In
the event of smoke or malodorou
s 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 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 excessive 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.
MAINTENANCE
The surface of the stove has been treated with heat-resistant paint.
The stove should be cleaned with a
damp cloth. Any damage to the surface in the form of chips or scratches
can be repaired using touch-up paint,
which is available in spray cans.
Cleaning the glass
Incorrect firing, for example using wet
wood, can result in the viewing window
becoming covered in soot. This soot
can be easily and effectively removed
by using proprietary stove glass cleaner.
