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 15, Scan-Line 16 and
Scan-Line 16XL has been approved ac-
cording to the EN 13240/A2: 2004 and
15a B-VG.
Approval means that consumers can
be sure, that the stove meets a range
INSTALLATION INSTRUCTIONS
IMPORTANT
1. Make sure there is adequate provi-
sion to sweep the chimney.
2. Make sure there is adequate venti-
lation 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
surface used to cover the floor area
must match national and local regula-
tions.
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 corre-
of specifications and requirements
intended to ensure that the materi-
als used are of good quality, that the
stove does not adversely affect the en-
vironment, 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 en-
suring that the applicable regulations
have been met.
Distance regulations
A difference applies to installation
next to flammable and non-flamma-
ble walls.
If the wall is made of non-flammable
material the stove can, in principle, be
placed flush against it. However, we
recommend 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
ensure that children and
elderly or infirm people can not come
into contact with it.
Do not store any flammable materials
in the room below the ashpan.

sponds 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 dam-
per is in its “closed” position. If local
regulations permit, two contained fi-
replaces can be connected to the same
chimney. However, you must abide
by local regulations regarding the di-
stance between the two connections.
Wood-burning stoves must never be
connected to chimneys that are also
linked to a gasfired heater. An effi-
cient 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 it-
self, 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 chim-
ney, we recommend fitting the chim-
ney tube inside the flue gas spigot so
that any soot and condensation drops
into the stove itself rather than col-
lecting on the exterior surface of the
stove.
Changing from top to back outlet - see
figure 2-11 on page XX.
For connections to chimneys that are
run through ceilings, all national and
local regulations regarding distance
to flammable material must be follo-
wed. 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 chim-
ney (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 - see table on page 9. The flue
gas temperature at nominal output
is 257°C when expelled to an exterior
temperature of 20°C and the flue gas
mass flow - see table on page 9.
However, there will still be a risk of
smoke emission if the firing door is
opened during powerful firing. The
chimney draft is generated by the dif-
ference between the high tempera-
ture of the chimney and the low tem-
perature of the fresh air. The length
and insulation 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 in-
sulation, for example.
- The outdoor temperature is too
high – in summer, for example.
- No wind is blowing. - The chimney
is too low and sheltered. - The chim-
ney 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 air-
flow 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 blo-
wing strongly.
- The chimney is of the correct height:

at least 4.00 m above the stove and
free of the roof ridge.
First firing
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 malodo-
rous 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 fi-
ring with wood fuel. You must there-
fore only burn clean, dry wood in your
stove. Never use your stove to
burn
driftwood, 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 ma-
ximum economy. At the same time,
correct firing prevents environmental
damage in the form of smoke and em-
missions 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 va-
porise the water, and this will all disap-
pear up the chimney. Thus it is impor-
tant 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 diame-
ter of more than 10 cm should be split
before storing. The pieces of firewood
should be of an appropriate length (ap-
prox. 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.

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 se-
condary/start-up air supply to smother
the fire. Call the fire department.
Regulating the airflow
Primary airflow is added using the pri-
mary airflow control on the ashpan
and the secondary airflow using the
handle at the right below the ashpan.
Pulling the handle fully in or out closes
or opens the secondary airflow.

5
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. Complet-
ely 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 em-
bers. Distribute the embers across the
bottom grate, place pieces of fuel
(max. 1,6 kg) on the embers in a single
layer perpendicular to the firing ope-
ning. Close the firing door and use pri-
mary air if needed. The wood will then
ignite very quickly (within 30 to 60
seconds). When the wood is burning
with a steady flame, close the prima-
ry airflow. Then adjust the secondary
airflow to the required amount. For
nominal operation, the secondary air-
flow should be fully open and the pri-
mary airflow closed. When firing, take
care not to pack the fuel too closely
together, as this will result in poor and
inefficient combustion. Please note
that the primary airflow must be clo-
sed during normal operation, other-
wise the stove may overheat. 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,
remember that the secondary combu-
stion air supply must never be shut off
completely during firing. It is impor-
tant 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 con-
verted to glowing embers.
Optimal firing
To achieve optimal firing and the hig-
hest possible effect, it is important to
make sure that the air supply is used
correctly. As a general rule, the second-
ary
air is to be used to control the fire
to ignite the flue gases. This produ-
ces 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, natu-
rally, produce soot if both the primary-
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 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 con-
stantly. This will normally occur wi-
thin 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 combu-
stion chamber.

The nominal output is the output to which the stove has been tested. Testing should be carried
out with the primary airflow closed and the secondary airflow fully open.
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 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 possi-
ble to regulate the fire. Please note,
however, that chimney draft is de-
pendent 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 ca-
ses 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 ash-
pan seal is intact and correctly fitting.
If the stove it generating too little
heat, this may be because you are fi-
ring 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 tre-
ated 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. If the stove has
become grey in colour due to overhea-
ting, touch-up paint of this kind can
be used to repaint the stove entirely.
However, in this case, the stove should
be dismantled and the surface treat-
ment should be performed outdoors
or in a purpose-built room.
Cleaning the glass
Incorrect firing, for example using wet
wood, can result in the viewing win-
dow becoming covered in soot. This
soot can be easily and effectively rem-
oved by using proprietary stove glass
cleaner.
