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 800 series and the Scan-
Line 800 series with side windows have
both been approved according to the
EN 13240, NS 3058/3059, 15a B-VG and
Defra approved for use in smoke control
areas throughout the UK.
IMPORTANT
1. Make sure there is adequate provi-
sion 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 sur-
face 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 regulations.
The chimney connection
The chimney opening must follow natio-
nal 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
Approval means that consumers can
be sure, that the stove meets a range of
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:
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 chim-
ney 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 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 can
not come into contact with it.
Combustible materials should not be
stored in the compartment below the
ashpan.
INSTALLATION INSTRUCTIONS

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 800 series can be instal-
led with a horizontal straight back outlet.
Maximum length of the pipe should be
500 mm with a 5” diameter. The start
draft of the chimney (cold stove) should
be the described necessary draft men-
tioned in this instruction.
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. Changing
smoke outlet from top-mounted to rear-
mounted (see fig. 9-16 on page 12).
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 cause damage on or noise from 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 for the Scan-Line
800 series and 12 PA for the Scan-Line
800 series with side windows. However,
there will still be a risk of smoke emis-
sion if the firing door is opened during
powerful firing. The flue gas tempera-
ture at nominal output is 272°C for the
Scan-Line 800 series and 277°C for the
Scan-Line 800 series with side windows
when expelled to an exterior temperature
of 20°C. The flue gas mass flow is 5.6
g/sec. for the Scan-Line 800 series and
5.3 g/sec. for the Scan-Line 800 series
with side windows. 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 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).

4
INSTRUCTIONS FOR USE
• 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.
First firing
The stove paint is fully cured from the fac-
tory, but a minor unpleasant odour could
still arise. During the first firing, which
should be carried out using approximatly
1,5 kg. of wood, the stoking door must
be opened slightly every 10 minutes for
the first two hours 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. Ne-
ver 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-im-
pregnated wood or chipboard, as these
materials can emit poisonous fumes and
smoke. Correct firing using well seaso-
ned wood provides optimal heat output
and maximum economy. At the same
time, correct firing prevents environ-
mental 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 diameter
of more than 10 cm should be split befo-
re 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 outdo-
ors, it is best to cover it.
Fuels used in smoke control
areas
In a building in a smoke control area
you are legally only allowed to use this
appliance to burn dry/seasoned wood
logs of the maximum length given above
or authorised fuels. If you are unsure
if your property is located in a smoke
control area or need further guidance
on fuels you should contact your Local
Authority.

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.

It is advised not to use very oil-conta-
ining woods like teak tree and maho-
gany, 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 CO2
neutral 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 secondary/
start-up air supply to smother the fire.
Call the fire department.
Airflow regulation
To adjust combustion airflow, use the
handle on the side (towards the rear).
There is maximum combustion airflow
in when the handle is in the top position
(fig. 1). Reduce combustion airflow gra-
dually by lowering the handle. When the
Fig. 1 Fig. 2
Open Closed
The SL800 stoves are designed and te-
sted to burn extremely cleanly with very
little smoke discharge and are exempt
for use in smoke control areas throug-
hout the UK when burning dry wood
logs. To comply, a permanent stop is
fitted to ensure that the air control slider
cannot be closed beyond 31% of its fully
open position. A permanent amount of
air will therefore enter the firebox to feed
the fire producing negligible amounts of
smoke and unburnt hydrocarbons. The
appliances will only be considered as
an exempt appliances if this stop is in
place.
Lighting the stove
To light the stove, use firelighters, paraf-
fin firelighter bags or small pieces of
wood. Place over the grate. Place larger
logs over the fire-lighting material, at
right angles to the door. Turn handle to
top position for max. Combustion- air-
flow. The stove door should be slightly
ajar (about 1 cm). When the wood is well
lit and the chimney is hot (after about 10
minutes), close the stove door. When
lighting the stove from cold, we re-
commend that the combustion airflow is
at maximum until the first stack of wood
has burned out so that the stove and
chimney are heated through.
handle is in the lowest position (fig. 2),
combustion airflow is completely closed.

3. With plenty of air the flames will burn
brightly quickly warming the stove and
chimney.
4. After about 5/10 minutes and with the
fire established the door can be shut
and the stove can be controlled by the
airslider. Adjust the airslider to control
the burning rate and to give optimum
combustion.
5. After about 40/50 minutes and when
the last flames go out a red hot ember
bed will be left and further wood can be
added.
6. Place 2/3 logs on the ash bed ensu-
ring that the wood is not stacked too
closely and with the adjust the side
airslider to fully on position. The wood
will light in 2/3 minutes. Adjust the air
slider for optimum combustion.
Lighting instructions for Heta stoves
1. Place some scrunched up newspaper
and firelighters on the base of the stove
and stack some small pieces of wood/
kindling on top into about 3 layers lea-
ving gaps in between.
2. Fully open the ”side” air control.
Light the firelighters and leave the door
slightly ajar to allow air to enter and the
fire to establish.

7
Once the flames have taken hold, the
air supply can be regulated to give the
required amount of heat.
Note:
If the fire dies down completely or
embers are smoldering then it will be
necessary to place some screwed up
paper or firelighters onto the grate with
some kindling or small pieces of wood
to reestablish the fire once again. Leave
the airsliders fully open and allow the
fire to build before refueling with larger
pieces of wood and then adjust the
sliders for optimum combustion.
Do not overload the firebox by loa-
ding above the tertiary air diffuser at
the back of the firebox and ensure
that the wood is retained by the log
guard. Always ensure that the wood
is not tightly stacked so that air can
circulate freely.
Do not leave the door open: Opera-
tion with the door open can cause
excess smoke. The appliance must
not be operated with the appliance
door left open except as directed in
the instructions.
Do not leave the airsliders completely
open: Operation with the airsliders
permanently open can cause excess
smoke. The appliance must not be
operated with air controls or dampers
left open except as directed in the
instructions.
Refuelling
A fresh supply of fuel should normally
be added while there is still a good layer
of hot embers. Spread the embers over
the base grate, most towards the front
of the stove. Lay a single layer of wood
fuel corresponding to about 1.5 kg over
the embers, at right angles to the stove
door. Turn handle into top position (max.
Combustion- airflow). Keep door ajar if
necessary. (The door should not be left
open but fuel will ignite more quickly
while the door is ajar.) The wood should
ignite within a very short time (usually
1-3 minutes). If the door is ajar, close
it as soon as the fuel is ignited. When
the flames spread across the fuel stack,
adjust the combustion airflow to the
required level. Nominal operation 6 kW
corresponds to 80% combustion airflow.
When adding fuel, make sure that the
fuel is not too tightly packed, as this will
lead to poorer combustion and fuel inef-
ficiency.
Never fill firewood over the stove’s max.
fill line. See fig. 3.
Reduced rate of combustion
The stove is suitable for intermittent use.
Max. fill line.
Fig. 3
If you require a lower rate of heat effect,
fill the combustion chamber with less
wood. Allow lower combustion airflow.
Do not forget that the combustion airflow
must never be completely closed when
lighting up. It is important to maintain
the layer of embers. Low-effect heating
is achieved when the wood is glowing,

8
Risk of explosion
After you add new fuel, it
is very important that you do
not leave the stove unat
tended 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 explo-
de 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.
i.e. there are no more flames because
the wood fuel has been transformed into
glowing charcoal.
Optimal combustion
For optimal combustion and heating, this
stove is designed to provide an optimum
mix of primary and secondary air (in
these instructions, we call this combu-
stion air). The stove provides excellent
heating efficiency and the window is
easy to maintain as the secondary air
‘flushes’ the surface of the glass. Note
that the stove will, of course, blacken if
the airflow is too low. If there is too little
oxygen, there is a risk that the window,
etc. will
Blacken due to the formation of soot
deposits. A combination of incorrect
combustion and damp wood fuel can
cause a heavy, sticky coat of soot to
form, which may cause the door seal to
tear off next time the door is opened.

The chimney must be swept at least
once a year, we recommend the use of
a NACS (national association of chimney
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 wea-
ther 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 exces-
sive 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,
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
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.
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.
VENTILATION
Adequate ventilation must be provided
in accordance with building regulations
(Doc J Oct 2010) especially when instal-
ling 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 5m3/hour/m2then a
ventilator equivalent to 550mm2per kW
output will be required (5.5kW x 550mm
= 3025mm2).

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 800 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.
