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 ap-
proved according to the EN 13240,
NS 3058/3059, 15a B-VG.
Approval means that consumers can
Combustible materials should
not be stored in the compartment
below the ashpan.
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 nonflam-
mable surface used to cover the floor
be sure, that the stove meets a range
of specifications and requirements
intended to ensure that the materi-
als 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.
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-flammable
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 8.
Warning
A stove gets hot. (In excess
of 90 degrees) Take care to
en sure that children cannot
come into contact with it.

area must match national and local
regulations.
The chimney connection
The chimney opening must follow
national and local regulations. Howe-
ver, 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 passage, even when
the damper is in its “closed” position.
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.
The Scan-Line 7 series can be instal-
led with a horisontal straight back
outlet.
Maximum length of the pipe should be
500 mm with a 5” diameter.
The start draft (cold stove) of the
chimney should be at least 6 pascal.
Connection to a brick chim-
ney
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 chim-
ney
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 smoke outlet from
top-mounted to rear-mounted (see fig.
12-19 on page 18).
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 combu-
stion 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 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 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 insulation
of the chimney, wind and weather
conditions also have an effect on the
ability of the chimney to generate ap-
propriate 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.

INSTRUCTIONS FOR USE
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
driftwood, as this
may contain a lot of salt which can da-
mage 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 inade-
quately 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 seaso-
ned 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 diameter 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 em-
bers. If you store your wood outdoors,
it is best to cover it.
Examples of recommended
woods types
and their typical specific gravity per
cubic meter stated as 100% wood
with a moisture content of 18%
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 shel-
tered.
• 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.
• 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-
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.
CO2release
At combustion 1000 litres of heating oil
forms 3.171 tons CO2. As wood is a
CO2neutral heat/ energy source, you
save the environment about 1.3 kg
CO2every 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 se-
condary/start-up air supply to smother
the fire. Call the fire department.
Airflow regulation
The stove is supplied air by means
of the control handles placed at the
back of the side panel. The secondary
airflow handle is the upper handle and
the one for the the start-up airflow is
the one below. See figure 1.
The secondary airflow is completely
open in top position. Shut off the se-
condary airflow gradually by lowering
the handle and is completely closed in
bottom position. The start-up airflow
is completely open in top position.
Shut off the damper gradually by lo-
wering the handle to the bottom.
Fig. 1
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. Complete-
ly 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.
Refuelling
You should normally refire the stove
while there is still a good layer of

6
embers. Distribute the embers across
the bottom grate, place pieces of fuel
(max 0.7 kg) on the embers in a single
layer perpendicular to the firing ope-
ning. 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 le-
vel required. For nominal operation (4
kW), the secondary air supply should
be 50% open. When firing, take care
not to place the pieces of fuel too clo-
sely together, as this will result in poor
combustion and insufficient exploita-
tion 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 intermit-
tent use. If you wish to operate the
stove with reduced output, simply
insert smaller volumes of wood at
each firing, and apply a lower airflow.
However, remember that the second-
ary 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 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 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 una-
ttended until the wood is burning
constantly. This will normally occur
within 30 to 60 seconds.
A risk of explosion can possibly arise
if too much wood is placed in the st-
ove. 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.

OPERATIONAL PROBLEMS
The chimney must be swept at least
once a year, we recommend the use
of a NACS (national association of
chimney sweeps) registered chim-
ney sweep. In the event of smoke or
malodorous fumes being produced,
you must first check to see whether
the chimney is blocked. The chim-
ney 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 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 cor-
rectly 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 eco-
nomics and an increased risk of soot
deposits in the chimney.
Check whether the air holes in the
stones 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.
Take care when emptying the ash pan, as cin-
ders can continue to burn in the ash for long
periods of time.

VENTILATION
Adequate ventilation must be provided
in accordance with building regulati-
ons (Doc J Oct 2010) especially when
installing in newer build properties
when the stove is not going to be
installed to an outside air supply.
The Heta SL800 requires a permanent
air vent opening of minimum 550sq
mm under Building Regulations if
the stove is not going to be fitted to
an external outside fresh air supply.
Houses built after 2008 where the air
leakage rate is less than than 5 m3/
hour/m2then a ventilator equivalent to
550mm2per kW output will be re-
quired (4kW x 550mm = 2200 mm2).

Wall-mounting the stove
Attach the wall fitting (can be used as
a drilling template) to a non-combusti-
ble wall with four bolts dimensioned to
bear the weight of the stove (weight:
see table page 6). Do not use plastic
rawlplugs (due to heat from the stove).
If smoke is to escape from rear flue
outlet at the back of the stove, fit the
wall bushing before hanging the stove
on the wall. To switch from top flue
outlet to rear flue outlet, see page 12.
There are four wall brackets on the
back of the stove. The lower wall
brackets on the stove just rest on the
lower side screws of the wall fitting.
See figure 3. When the stove is resting
on the lowest screws, tip the stove
to meet the wall fitting and secure
with the screws and shims supplied.
Never store solid fuel or combustible
material under the stove.

The Clean Air Act 1993 and Smoke
Control Areas
Under the Clean Air Act local autho-
rities may declare the whole or part
of the district of the authority to be a
smoke control area. It is an offence to
emit smoke from a chimney of a buil-
ding, from a furnace or from any fixed
boiler if located in a designated smoke
control area. It is also an offence to
acquire an ”unauthorised fuel” for use
within a smoke control area unless
it is used in an ”exempt” appliance
(”exempted” from the controls which
generally apply in the smoke control
area).
The Secretary of State for Environ-
ment, Food and Rural Affairs has
powers under the Act to authorise
smokeless fuels or exempt applian-
ces for use in smoke control areas in
England. In Scotland and Wales this
power rests with Ministers in the de-
volved administrations for those coun-
tries. Separate legislation, the Clean
Appendix A
Air (Northern Ireland) Order 1981, ap-
plies in Northern Ireland. Therefore it
is a requirement that fuels burnt or ob-
tained for use in smoke control areas
have been ”authorised” in Regulations
and that appliances used to burn solid
fuel in those areas (other than ”aut-
horised” fuels) have been exempted
by an Order made and signed by the
Secretary of State or Minister in the
devolved administrations.
The Scan-Line 7 series have been
recommended as suitable for use in
smoke control areas when burning dry
wood logs.
Further information on the require-
ments of the Clean Air Act can be
found here : http://smokecontrol.
defra.gov.uk/
Your local authority is responsible for
implementing the Clean Air Act 1993
including designation and supervision
of smoke control areas and you can
contact them for details of Clean Air
Act requirements.
