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 7 series has been appro-
ved according to the DIN EN 13240, NS
3058/3059, DINplus and 15a B-VG.
Approval means that consumers can be
sure, that the stove meets a range of
specifications and requirements inten-
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 oor
It is essential to ensure that the floor
surface can actually bear the weight of
the stove and a top-mounted steel chim-
ney, 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 surface
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 cm
2
, which corresponds
to a diameter of 150 mm. If a damper is
fitted in the flue gas pipe, there must al-
ways be at least 20 cm
2
of free passage,
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:
a. Operating instructions
b. 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. The-
refore, 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.
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 ammable
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 ensure
that children and elderly or
inrm people cannot come into
contact with it.
Combustible materials should
not be stored in the compart-
ment below the ashpan.
INSTALLATION INSTRUCTIONS

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.
Wood-burning stoves must never be
connected to chimneys that are also
linked to a gasred 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 thim-
ble 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 thim-
ble 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. Changing
smoke outlet from top-mounted to rear-
mounted (see fig. 12-19 on page 12).
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 power-
ful firing. The flue gas temperature at
nominal output is 237°C when expelled
to an exterior temperature of 23°C. The
flue gas mass flow is 3.2 g/sec. The chim-
ney
draft is generated by the difference
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 condi-
tions 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 com-
pensated 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.
- The chimney is of the correct height: at
least 4.00 m above the stove and free
of the roof ridge.

It is advised not to use very oil-conta-

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 CO
2
. As wood is a CO
2
neutral heat/ energy source, you save
the environment about 1.3 kg CO
2
every
time you have used 1 kg normal wood.
Chimney res
In the event of a chimney fire – which
often results from incorrect operation
or protracted firing with moist wood –
INSTRUCTIONS FOR USE
First ring
The stove has been treated with a heat-
resistant coating which hardens 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 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
environmen-tal 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. 18 cm) so that they can lie flat
on the bed of embers. If you store your
wood outdoors, it is best to cover it.

close the door and shut off the seconda-
ry/start-up air supply to smother the fire.
Call the fire department.
Lighting and combustion
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 kind-
ling material, at right angles to the firing,
doors. Completely open the start-up and
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.
Rering
You should normally refire the stove
while there is still a good layer of embers .
Distribute the embers across the bot-
tom grate, place pieces of fuel (max
0.7 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 no-
minal operation
(4 kW), the secondary
air supply should be 50% open. When
firing, take care not to place the pieces
of fuel too close-ly together, as this will
result in poor combustion and insuf-
ficient exploitation of the fuel. 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 smal-
ler volumes of wood at each firing, and
apply a lower airflow. However, remem-
ber that the secondary combustion air
supply must never be shut off complet-
ely 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 ring
To achieve optimal firing and the hig-
hest possible effect, it is important to
make sure that the air supply is used cor-
rectly. As a general rule, the secondary
air is to be used to control the fire to ig-
nite the flue gases. This produces a high
effect and keeps the glass panel com-

pletely clear of soot as the secondary
air “washes” down over it. Please note
that the stove will, naturally, produce
soot if both the start-up mechanism and
secondary air intakes are closed complet-
ely. 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 occur
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 comb-
stion chamber.
Take care when emptying the ash pan,
as cinders can continue to burn in the
ash for long periods of 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 pro-
vide the minimum draught necessary to
ensure that it is possible to regulate the
fire. Please note, however, that chim-
ney 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
turning 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 is intact and correctly fitting.
If the stove it generating too little heat,

7
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.
Check whether the air holes in the sto-
nes are blocked with for example ashes
etc. Below the casted shaking grate is it
possible to clean the air channel for the
start-up airflow.
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
in the form of chips or scratches can be
repaired using touch-up paint, which is
available in spray cans.
Cleaning the glass
MAINTENANCE
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.
Door sealing
It is recommened at least once a year to
check the sealing of the door to see if it
is intact and correctly fitting. (See figure
2)
