Safety
Please note: All safety regulations must be
complied with strictly.
Please read carefully the instructions supplied
with the appliance for installation, use and
maintenance, before using the appliance.
The appliance must be installed in accordance
with the laws and requirements of your
country.
All local regulations and the regulations relating
to national and European standards must be
observed when installing the appliance.
The appliance should preferably be installed by
an authorized installer. Installers will be aware
of the applicable regulations and requirements.
The appliance is designed for heating
purposes. All surfaces, including the glass and
connecting tube, can get very hot (over 100°C)!
For operation, use a so-called "cold hand" or an
oven glove.
Safety distances from flammable materials
must be adhered to strictly.
Don't place any curtains, clothes, laundry or
other combustible materials on or near the
appliance.
Don't use flammable or explosive substances
near the appliance when it is in use.
Avoid a chimney fire by having the chimney
swept regularly. Never burn wood with the door
open.
In the case of a chimney fire: close all air inlets
of the appliance and alert the fire brigade.
If the glass in the appliance is broken or
cracked, it must be replaced before you can
use the appliance again.
Make sure there is adequate ventilation in the
room where the appliance is installed. If
ventilation is insufficient, combustion will be
incomplete resulting in toxic gases being
produced and spread through the room. See
the chapter "Installation requirements" for more
information on ventilation.
Installation
requirements
General
The appliance must be connected tightly to a well-
functioning chimney.
For the connection measurements: see the
appendix "Technical data".
Ask the fire brigade and/or your insurance
company about any specific requirements and
regulations.
Chimney (flue)
The flue or chimney is needed for:
Removal of combustion gases via natural draught.
As the warm air in the flue or chimney is lighter
than the outside air, it rises.
Air intake, needed for the combustion of fuel in the
appliance.
A poorly-functioning flue or chimney can cause smoke
to escape into the room when the door is opened.
Damage caused by smoke emissions into the room is
not covered by the warranty.
Do not connect multiple appliances (such as a
boiler for central heating) to the same flue,
unless local or national regulations allow this.
In the event of two connections ensure that the
difference in height between the connections is
no less than 200 mm.
Ask your installer for advice regarding the flue. Refer
to the European norm EN13384 for a correct
calculations for the flue.
The flue must satisfy the following requirements:
The flue or chimney must be made of fire-resistant
material, preferably ceramics or stainless steel.
The flue or chimney must be airtight and well-
cleaned and guarantee sufficient draught.
4Subject to change because of technical improvements

A draught/vacuum of 15-20Pa during normal
operation is ideal.
Starting from the flue spigot, the flue must run as
vertically as possible. Changes in direction and
horizontal pieces disrupt the outward flow of
combustion gases and may cause soot deposits.
To prevent combustion gases from cooling down
too much, which reduces the draught, ensure that
the interior diameter is not too big.
The flue or chimney should ideally have the same
diameter as the connection collar.
For the nominal diameter: see the appendix
"Technical data". If the smoke channel is well
insulated, the diameter may be slightly bigger
(up to 2x the section of the connection collar).
The section (area ) of the smoke channel must be
constant. Wider segments and (in particular)
narrower segments disrupt the outward flow of
combustion gases.
When using a cover plate or exhaust hood : make
sure that the cover does not restrict the flue outlet
and that the cap does not impede the outward flow
of combustion gases.
The flue must end in a zone that is not affected by
surrounding buildings, trees or other obstacles.
The flue outside the house must be insulated.
The chimney must be at least 4metres high.
As a rule of thumb: 60cm above the ridge of the
roof.
If the ridge of the roof is more than 3metres away
from the flue: stick to the measurements in the
following figure. A = the highest point of the roof
within a distance of 3metres.
Ventilation of the area
For good combustion, the stove needs air (oxygen).
This air is supplied via adjustable air inlets from the
area in which the stove is installed.
The combustion will be incomplete in case of
insufficient ventilation, which results in toxic
gases being produced and spread through the
area.
As a rule of thumb, the air supply should be 5,
5cm²/kW. Extra ventilation is needed when:
The stove is in an area that is well-insulated.
There is mechanical ventilation, for example a
central extraction system or an extraction hood in
an open kitchen.
You can provide extra ventilation by having a
ventilation louvre fitted on the outside wall.
Make sure that other air consuming appliances (such
as tumble-driers, other heating appliances or a
bathroom fan) have their own supply of outside air, or
are switched off when you use the appliance.
You can also connect the appliance to an
outside air supply. A connection kit is supplied
for this purpose. This makes additional
ventilation unnecessary.
Floors and walls
The floor on which the appliance is placed must have
sufficient bearing capacity. For the weight of the
appliance, see the appendix "Technical data".
Protect flammable flooring from heat radiation
by means of a fireproof protective plate. See
the appendix "Distance from combustible
material".
Remove combustible material such as
linoleum, carpets/rugs and similar materials
below the fireproof protective plate.
Keep sufficient distance between the
appliance and combustible materials such as
wooden walls and furniture.
The connecting tube also radiates heat. Ensure
that there is sufficient distance or a shield
between the connecting tube and combustible
Subject to change because of technical improvements 5

material.
The rule of thumb for a single-walled tube is a
distance of 3x the diameter. If a lining shell is
fitted around the tube, a distance of 1x the
diameter is permissible.
Carpets and rugs must be at least 80cm away
from the fire.
Use a fireproof floor plate to protect a
flammable floor from any ash which may fall in
front of the stove. The protective plate must
comply with national standards.
For the dimensions of the fireproof protective
plate: see the appendix "Distance from
combustible material".
For further requirements in connection with fire
safety: see the appendix "Distance from
combustible material".

Preparing the outside air
connection
If the appliance is installed in a room without sufficient
ventilation, you can install the connecting kit on the
appliance for the supply of outside air.
The air supply tube is 100mm in diameter. If using a
smooth tube, it may be no longer than 12metres long.
If accessories such as bends are used, the maximum
length (12metres)) must be reduced by 1metre for
each accessory used.
Outside air connection via the wall
1. Make an opening in the wall (see the appendix,
"Measurements", for the correct position of the
opening).
2. Close the air connection hermetically to the wall.
Installing and connecting
1. Position the stove in the correct place, and make
sure it is level.
2. Connect the appliance airtight to the flue
(chimney).
8Subject to change because of technical improvements

3. In the case of connection to outside air: connect
the outside air supply to the connector fitted to the
appliance.
4. Re-position all removed parts in the correct places
in the stove.
Never light a fire in the appliance without the
fireproof inner plates.
The appliance is now ready for use.
Use
First use
When you use the stove for the first time, make an
intense fire and keep it going for a good few hours.
This will cure the heat-resistant paint finish. This may
result in some smoke and odours. You could open
windows and doors for a while in the area in which the
stove is located.
Fuel
The appliance is a multi fuel stove. This stove is
suitable for burning natural wood; sawn and split wood
that is sufficiently dry. The appliance is also suitable
for the burning of brown coal briquettes and anthracite
coal.
Do not use other fuels, as they can cause serious
damage to the stove.
You are not allowed to use the following fuels, as they
pollute the environment and because they heavily soil
the appliance and flue, which may lead to a chimney
fire:
Treated wood, such as scrap wood, painted wood,
impregnated wood, preserved wood, plywood and
chipboard.
Plastics, scrap paper and domestic waste.
Wood
Hardwood, such as oak, beech, birch and fruit tree
wood is the ideal fuel for your stove. This type of
wood burns slowly with calm flames. Softwood
contains more resins, burns faster and sparks
more.
Use seasoned wood that contains no more than
20% moisture. The wood should have been
seasoned for at least 2 years.
Saw the wood to size and split it while it is still
fresh. Fresh wood is easier to split, and split wood
dries more easily. Store the wood under a roof
where the wind has free access.
Do not use damp wood. Damp logs do not produce
heat as all the energy is used in the evaporation of
moisture. This will result in a lot of smoke and soot
deposits on the stove door and in the chimney. The
water vapour will condense in the stove and can
leak away through chinks in the stove, causing
black stains on the floor. It may also condense in
the chimney and form creosote. Creosote is a
highly flammable compound and may cause a
chimney fire.
Brown coal briquettes
Brown coal briquettes have approximately the same
burning characteristics as wood.
Ensure there is a good charcoal bed before you
start burning brown coal briquettes.
For lighting the fireplace, follow the instructions in
the "Lighting" paragraph.
Anthracite coal
Anthracite coal is categorised on the basis of
characteristics, sometimes prescribed by law, such
as the percentage of volatile substances. The ash
content of anthracite coal is between 3% and 13%.
The lower the ash content, the higher the net heating
value and the less often you have to remove ash.
Preferably use category A anthracite coal with a
low ash content.
Use the recommended size 12/22 or 20/30.
For lighting the fireplace, follow the instructions in
the "Lighting" paragraph.
Lighting
You can check whether the flue has sufficient draught
by lighting a ball of paper above the baffle plate. A cold
flue often has insufficient draught and consequently,
some smoke may escape into the room instead of up
Subject to change because of technical improvements 9

the chimney. You can avoid this problem by lighting
the fire as described below.
1. Stack two layers of medium sized logs crosswise.
2. Stack two layers of kindling crosswise on top of
the logs.
3. Place a firelighter cube in the lower layer of
kindling and light the cube according to the
instructions on the packaging.
4. Close the door of the appliance and open the
primary air inlet and the secondary air inlet of the
appliance; see the following figure.
5. Allow the fire develop into a good blaze until there
is glowing bed of charcoal. You can then add fuel
and adjust the appliance, see the chapter "Stoking
with wood".
Open Closed
Burning wood
After you have followed the instructions for lighting :
1. Slowly open the stove door.
2. Spread the charcoal evenly across the bottom of
the stove base.
3. Stack a few logs on the charcoal.
Open stacking
If the logs are stacked openly, the wood will burn
quickly as the oxygen can reach each log easily. If
10 Subject to change because of technical improvements

you want to use the stove for a short while, make an
open stack.
Compact stacking
If the logs are stacked tightly, the wood will burn more
slowly as the oxygen can only reach some logs
easily. If you want to burn wood for a longer period,
make a compact stack.
4. Close the door of the appliance.
5. Close the primary air inlet and leave the secondary
air inlet open.
Fill the appliance up to one third capacity.
Burning brown coal
briquettes
Brown coal briquettes burn in almost the same way as
wood. Using the primary air inlet, ensure sufficient
supply of air under the fire. For further information see
the paragraph "Burning wood".
Burning brown coal briquettes creates a lot of ash.
Regularly remove excess ash. See the paragraph
"Removing ashes" for instructions.
For the properties and use of brown coal
briquettes: consult your brown coal briquettes
supplier or see the brown coal briquettes'
packaging.
After you have followed the instructions for lighting:
1. Slowly open the stove door.
2. Spread the charcoal evenly across the bottom of
the stove base.
3. Place the brown coal briquettes on the charcoal
bed.
4. Close the door.
5. Regularly remove ashes from the stove base
riddling the grate. Use the cold handle to operate
the riddling rod.
Burning anthracite coal
Always close the secondary air slide when
burning anthracite coal.
Set the fuel choice air valve to the closed
position.
After you have followed the instructions for lighting:
1. Open the primary air slide completely.
2. Slowly open the stove door.
3. Spread the charcoal evenly across the bottom of
the stove base.
4. Spread a shovelful of coal on the charcoal bed and
wait with the next shovelful until the coals start to
glow.
5. Now add more coal.
Be careful not to smother the fire by adding too
much coal at once.
You have added as much as you can once the
glow of the previous load is only just visible.
6. Close the door.
7. Allow the coals to burn well for a few minutes and
control the air supply using the primary air slider.
If the fire basket or the cast-iron plates start to
glow red you have overfed the fire.
8. Regularly remove ashes from the stove base
riddling the grate. Use the cold handle to operate
the riddling rod.
Controlling combustion air
The appliance has various features for air control; see
following figure.
Subject to change because of technical improvements 11

The primary air slide controls the air flow under the
grille (1).
The secondary air slide controls the air flow for the
glass (airwash-system) and air supply via the vents in
the back wall (2).
The back wall has permanent vents (3) below the
baffle plate that allow for post-combustion.
Advice
Never burn wood with an open door.
Regularly burn wood with intense roaring fires.
If you frequently have low intensity fires, tar
and creosote may be deposited in the chimney
. Tar and creosote are highly combustible
substances. Thicker layers of these
substances may catch fire if the temperature in
the chimney increases suddenly. By allowing
the fire to burn very intensely regularly, layers
of tar and creosote will disappear.
Low intensity fires also cause tar deposits on
the stove window and door.
When the outside temperature is not very low,
it is better to burn wood intensely for a few
hours instead of having a low intensity fire for a
long period of time.
Control the air supply with the secondary air inlet.
The secondary air inlet not only supplies air to
the fire but to the glass as well, so that it does
not quickly become dirty.
Open the primary air inlet for the time being if the air
supply by the secondary air inlet is inadequate or if
you want to fan the fire.
It is better to add a small amount of logs regularly
than to add many logs at the same time.
Extinguishing the fire
Do not add fuel and just let the fire go out. If a fire is
damped down by reducing the air supply, harmful
substances will be released. For this reason, the fire
should be allowed to go out naturally. Keep an eye on
the fire until it has gone out. All air inlets can be closed
once the fire has died completely.
Removing ashes
After the wood has been burnt, a relatively small
amount of ashes is left over. This bed of ashes is a
good insulating layer for the stove base plate and
improves combustion. It is good to leave a thin layer
of ashes on the stove base plate.
However, the flow of air through the fire plate must not
be obstructed and no ash may be allowed to
accumulate behind a chamotte inner plate. Remove
the excess ash regularly.
After the brown coal briquettes and anthracite coal
has been burnt, a relatively large amount of ash is left
over. No ash may be allowed to accumulate
underneath the fire grate and the ash should never
reach the bottom of the grate. This will cause the grate
to overheat and be damaged.
12 Subject to change because of technical improvements

1. Use the riddling rod to free the grate (3) of excess
ashes.
If the appliance is still warm, use the "cold
hand" to operate the riddling rod.
2. Open the stove door.
3. Using the scraper (1) sweep the remaining ashes
through the grid.
4. Remove the ash pan (2) using the glove provided.
5. Empty the ash pan.
6. Put the ash pan back into the appliance.
7. Close the door of the appliance.
Fog and mist
Fog and mist hinder the flow of flue gases through the
flue. Smoke can blow back and cause a stench. If it is
not strictly necessary, it is better not to use the stove
in foggy and misty weather.
Solving problems
Refer to the appendix "Diagnostic diagram" to resolve
any problems in using the stove.
Maintenance
Follow the maintenance instructions in this chapter to
keep the stove in good condition.
Chimney
In many countries, you are required by law to have
your chimney checked and maintained.
At the beginning of the heating season: have the
chimney swept by an expert.
During the heating season and after the chimney
has not been used for a long time: have the
chimney checked for soot deposits.
After the heating season: seal off the chimney with
a ball of paper.
Cleaning and other regular
maintenance activities
Do not clean the stove when it is still warm.
Clean the exterior of the stove with a dry lint-free
cloth.
You can clean the stove interior thoroughly at the end
of the heating season:
If necessary, first remove the fire-resistant inner
plates. See the chapter "Installation" for
instructions on removing and installing the inner
plates.
If necessary, clean the air supply ducts.
Remove the baffle plate at the top of the appliance
and clean it.
Checking fire-resistant inner plates
The fire-resistant inner plates are consumables and
subject to wear . Check the fire-resistant inner plates
frequently and replace them when necessary.
Subject to change because of technical improvements 13

See the chapter "Installation" for instructions on
removing and installing the inner plates.
The insulating vermiculite or chamotte inner
plates may develop hairline cracks, but this
does not affect their performance adversely.
Cast-iron inner plates last a long time if you
remove frequently the ash that can accumulate
behind them. If accumulated ash behind the
cast-iron plate is not removed, the plate will no
longer be able to dissipate the heat to the
surroundings and this may cause the plate to
warp or crack.
Never use the stove without the fire-resistant
inner plates.
Cleaning glass
Dirt clings less easily to well-cleaned glass. Proceed
as follows:
1. Remove dust and loose soot with a dry cloth.
2. Clean the glass with stove glass cleaner:
a. Apply stove glass cleaner to a kitchen sponge,
rub down the entire glass surface and give the
cleaning agent time to react.
b. Remove the dirt with a moist cloth or kitchen
tissue.
3. Clean the glass again with a normal glass cleaning
product.
4. Rub the glass clean with a dry cloth or kitchen
tissue.
Do not use abrasive or aggressive products to
clean the glass.
Wear household gloves to protect your hands.
If the glass in the appliance is broken or
cracked, it must be replaced before you can
use the appliance again.
Make sure that no stove window cleaner runs
between the glass and the cast-iron door.
Lubrication
Although cast-iron is slightly self-lubricating, you will
still need to lubricate moving parts frequently.
Lubricate the moving parts (such as guide
systems,hinge pins, latches and air slides) with
heat resistant grease that is available in the
specialist trade.
Touching-up the paint finish
Small areas of damaged paint finish can be touched
up with a spraying can of special heat-resistant paint
finish available from your supplier.
Checking the seal
Check whether the door sealing rope is still in good
condition and works well. The sealing rope is
subject to wear and will need to be replaced over
time.
Check the appliance for air leaks. Close any
chinks with stove sealant.
Allow the sealant to harden fully before lighting
the stove, as any moisture in the sealant will
form bubbles, resulting in a new air leak.

Appendix 4: Diagnostic diagram
Problem
Wood will not stay lit
Gives off insufficient heat
Smoke emissions into the room when adding wood
Fire in stove is too intense, is hard to adjust
Deposit on the glass
Possible cause Possible solution
Insufficient draught A cold flue usuallyfails to create sufficient draught. Follow the
instructions for lighting in the "Use" chapter; open a window.
Wood too damp Use wood with no more than 20% moisture.
Logs too large Use small pieces of kindling. Use split logs no larger than 30 cm in
circumference.
Wood stacked incorrectly Stackthe logs in a way that allows adequate air flow between the
logs (open stacking, see "Burning wood")
Chimney does not work properly
Check whether the chimney meets the requirements: at least 4
metres high, right diameter, well insulated, smooth inside, not too
many bends, no obstructions in chimney (bird's nest, too much soot
deposit), hermetically tight (no chinks).
Chimney stack incorrect Sufficiently high above the roof, no obstacles in the vicinity
Air inlets set incorrectly Open the air inlets completely.
Stove connected to the chimney
incorrectly Connection should be hermetically tight.
Vacuum in area in which the stove is
installed Switch off extraction systems.
Insufficient supply of fresh air Provide an adequate air supply; if necessary use outside air
connection.
Adverse weather conditions?
Inversion (reversed air flow in chimney
because of a high outside temperature),
extreme wind speeds
We recommend you don't use the appliance in the case of inversion.
If required, install an extra hood on the flue to increase the draught.
Draught in the living room Avoid draught in the living room, do not place the appliance near a
door or heating air ducts.
Flames touch the glass Make sure the wood is not positioned too close to the glass. Slide the
primary air inlet cover closer to the "Closed" position.
Stove is leaking air Checkthe door sealsand stove joints.
