Installation and Operating Instructions for Heta SL800 stoves Pevex1019/AH/ver1:Jan 2013
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 ScanLine 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 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 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
regulations.
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.
Approval means that consumers can
be sure, that the stove meets a range of
specifications and requirements intended 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.
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. If the wall is made of nonflammable 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 can
not come into contact with
it. Combustible materials should
not be stored in the compartment
below the ashpan.
INSTALLATION INSTRUCTIONS
3
Installation and Operating Instructions for Heta SL800 stoves Pevex1019/AH/ver1:Jan 2013
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.
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.
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. 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
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 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 combu-
stion in stoves of this kind is 13 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 emission if the firing
door is opened during powerful firing.
The flue gas temperature at nominal
output is 274°C for the Scan-Line 800
series and 276°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 5.1 g/
sec. for the Scan-Line 800 series and
5.4 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 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.

INSTRUCTIONS FOR USE
Good draft occurs when:
• The difference in temperature
between the chimney and outdoor
air is high.
• The weather is fine.
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 malodorous
fumes, so the room must be very well
ventilated. 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. 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 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 diameter 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.
Fuels used in smoke control
areas
I
n 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.

It is advised not to use very oilcontaining 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.
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 gradually by lowering
the handle. When the handle is in the
lowest position (fig. 2), combustion
airflow is completely closed.
Fig. 1 Fig. 2
Open Closed
The SL800 stoves are designed and
tested to burn extremely cleanly with
very little smoke discharge and are
exempt for use in smoke control areas
throughout 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,
paraffin 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- airflow. 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 recommend 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.

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 ensuring 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 leaving 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
Installation and Operating Instructions for Heta SL800 stoves Pevex1019/AH/ver1:Jan 2013
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 loading 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: Operation 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 5.5 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 inefficiency.
Never fill firewood over the stove’s
max. fill line. See fig. 3.
Max. fill line.
Fig. 3
Reduced rate of combustion
The stove is suitable for intermittent
use. 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.

to form, which may cause the door
seal to tear off next time the door is
opened.
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
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 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.
Take care when emptying the ash
pan, as cinders can continue to burn
in the ash for long periods of time.
It is important to maintain the layer of
embers. Low-effect heating is achieved when the wood is glowing, 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 combustion 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

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
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,
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
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.
VENTILATION
Adequate ventilation must be provided
in accordance with building regulations (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 5m3/
hour/m2 then a ventilator equivalent to
550mm2 per 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 authorities 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 building, 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 Environment, Food and Rural Affairs has
powers under the Act to authorise
smokeless fuels or exempt appliances for use in smoke control areas in
England. In Scotland and Wales this
power rests with Ministers in the devolved administrations for those countries. Separate legislation, the Clean
Appendix A
Air (Northern Ireland) Order 1981, applies in Northern Ireland. Therefore it
is a requirement that fuels burnt or obtained for use in smoke control areas
have been ”authorised” in Regulations
and that appliances used to burn solid
fuel in those areas (other than ”authorised” 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 requirements 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.
