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 legislation and requirements applic-
able in 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 authorised installer. Installers will be aware
of the applicable regulations and requirements.
The appliance is designed for heating pur-
poses. All surfaces, including the glass and
connecting tube, can become very hot (over
100°C)! When operating, use a so-called "cold
hand" or an oven glove.
Ensure that the appliance is adequately
guarded if young children, disabled people, the
elderly or animals are present in the vicinity.
Safety distances from flammable materials
must be strictly adhered to.
Do not place any curtains, clothes, laundry or
other combustible materials on or near the appli-
ance.
When in use, do not use flammable or explos-
ive substances in the vicinity of the appliance.
Avoid chimney fires by having the chimney
swept regularly. Never burn wood with the door
open.
In the event of a chimney fire: close all the
appliance's air inlets and alert the fire service.
If the glass in the appliance is broken or
cracked, it must be replaced before the stove
is used again.
Do not exert force on the door, do not allow chil-
dren to pull on the opened door, never stand or
sit on the opened door and do not place heavy
objects on the door.
Ensure that there is adequate ventilation in the
room in which the appliance is installed. If vent-
ilation is insufficient, combustion will be incom-
plete whereby toxic gases can spread through
the room. See the chapter "Installation require-
ments" for more information on ventilation.
Installation
requirements
General
The appliance must be connected tightly to a well-
functioning flue.
For connection measurements: see "Technical
data" appendix.
Ask the fire service and/or your insurance com-
pany about any specific requirements and reg-
ulations.
Flue
The flue 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 cal-
culations 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.

6Subject to change because of technical improvements.
The flue or chimney must be airtight and well-
cleaned and guarantee sufficient draught.
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 com-
bustion 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 nominal diameter: see "Technical data"
appendix. If the smoke channel is well insu-
lated, 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) nar-
rower segments disrupt the outward flow of com-
bustion gases.
In fitting a cover plate/exhaust cap to the flue:
make sure that the cover does not restrict the flue
outlet and that the cap does not impede the out-
ward 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 flue should 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 from
the flue: use the measurements given in the fol-
lowing figure. A = the highest point of the roof
within a distance of 3metres.
Room ventilation
For good combustion, the appliance needs air (oxy-
gen). This air is supplied via adjustable air inlets from
the area in which the appliance is installed.
If ventilation is insufficient, combustion will be
incomplete, which may lead toxic gases to
spread through the room.
As a rule of thumb, the air supply should be
5.5cm²/kW. Extra ventilation is needed when:
The appliance is in a well-insulated area.
There is mechanical ventilation, for example a cent-
ral extraction system or an extraction hood in an
open kitchen.
You can provide extra ventilation by having a vent-
ilation louvre fitted on the outside wall.
Make sure that other air consuming appliances (such
as tumble-driers, other heating appliances or a bath-
room 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 out-
side air supply. A connection kit is supplied for
this purpose. This makes additional ventilation
unnecessary.
Floor and walls
The floor on which the appliance is placed must have
sufficient bearing capacity. The weight of the appli-
ance is given in the appendix “Technical Data
appendix”.
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 lino-
leum, carpets/rugs and similar materials below
the fireproof protective plate.
Keep sufficient distance between the appli-
ance and combustible materials such as
wooden walls and furniture.

Subject to change because of technical improvements. 7
The connecting tube also radiates heat. Ensure
that there is sufficient distance or a shield
between the connecting tube and combustible
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 dia-
meter is permissible.
Carpets and rugs must be at least 80cm away
from the fire.
Use a fireproof floor plate to protect a flam-
mable floor from any ash which may fall in front
of the stove. The floor plate must comply with
national standards.
For the dimensions of the fireproof protective
plate: see the appendix "Distance from com-
bustible material".
For further requirements with respect to fire
safety, see the appendix "Distance from com-
bustible material".

Installation
General preparation
Please check the appliance immediately after deliv-
ery for damage during transport or any other dam-
age or defects. The appliance is attached to the
pallet with screws at the bottom.
If you detect transport damage or any other
damage or defects, do not use the appliance
and notify the supplier.
Remove removable parts (fire-resistant inner
plates, fire grate, top plate, ashtray) from the appli-
ance before starting installation.
It is easier to move the appliance and to avoid
damage if the removable parts have been
removed.
Note the location of the removable parts, so
that you can re-position the parts in the correct
place later on.

Preparing the outside air
connection
If the appliance is installed in a room with insufficient
ventilation, you can install the outside air connecting
kit to the appliance.
The air supply tube is 100mm in diameter. If the tube
is smooth, it may be no longer than 12metres. If
accessories such as bends are used, the maximum
length (12m) must be reduced by 1m for each access-
ory 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 appliance in the correct place, and
make sure it is level. The appliance is designed
with adjustable feet, which may already be moun-
ted on the appliance or be included. Use these
adjustable feet so that the appliance can be placed
perfectly level.

3. Connect the appliance to the flue hermetically.
4. For outside air supply connection: connect the out-
side air supply to the connection kit which is fitted
to the appliance.
5. Re-position all removed parts to the correct places
in the appliance.
Never use the appliance without the fire-res-
istant inner plates.
The appliance is now ready for use.
Use
First use
When you use the appliance 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 win-
dows and doors for a while in the area in which the
appliance is located.
Fuel
This appliance is only suitable for burning natural
wood; sawn and chopped wood that is sufficiently dry.
Do not use other fuels, as they can cause serious
damage to the appliance.
The following fuels may not be used as they pollute
the environment, and because they heavily pollute 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. Wood with a mois-
ture content of 20% provides 4.2 kWh per kg wood.
Wood with a moisture content of 15% provides 4.4
kWh per kg wood. Freshly felled wood has a mois-
ture content of 60% and only provides 1.6 kWh per
kg wood.
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 appliance door and in the flue. The
water vapour will condense in the appliance 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 chim-
ney fire.
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
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 to three layers of kindling crosswise on
top of the logs.
3. Place a firelighter between the bottom layer of kind-
ling and light the firelighter according to the instruc-
tions on the packaging.

4. Close the appliance door and open the primary
and secondary air inlets; see the following figure.
5. Allow the fire develop into a good blaze until there
is a glowing bed of charcoal. You can then add fuel
and adjust the appliance, see the chapter "Stoking
with wood".

Burning wood
After you have followed the instructions for lighting:
1. Slowly open the door of the appliance.
2. Spread the charcoal evenly across the bottom of
the stove base.
3. Stack a few logs on the charcoal.
Open stacking
09-20500-017
If the logs are stacked openly, the wood will burn
quickly as the oxygen can reach each log easily. If
you want to use the stove for a short while, make an
open stack.

12 Subject to change because of technical improvements.
Compact stacking
09-20500-018
If the logs are stacked tightly, the wood will burn more
slowly as the oxygen can only reach some logs eas-
ily. 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 to a maximum of a third.
Maximum amount of wood
To stoke continuously at the rated power, wood must
be added every 45 minutes. If you use a smaller
amount of wood each time, you can add wood more
often. Each stove is designed to work with a specific
maximum amount of wood. If you use a larger quantity
of wood, the heat output increases: As a result, the
hearth can become overloaded and parts can be dam-
aged.
Permitted maximum quantity of fuel for wood with a
moisture percentage of 15%:
BOLD 7 KW has maximum filling of 1.5 kg wood per
45 minutes. Do not fill the combustion chamber more
that one third full, and never stack wood above the
openings for secondary air.
Controlling combustion air
The appliance has various features for air control; see
next figure.
09-20021-095

3
The appliance has one air slide that regulates both the
primary air and the secondary air inlet. If the air slide is
in position 3, the primary and the secondary air inlet is
open. As the air slide is further closed, the primary air
inlet and then the secondary air inlet is closed. If the
air slide is completely closed in position 1, a small air
vent remains open to allow for post-combustion under
the baffle plate.
09-20021-096

Subject to change because of technical improvements. 13
The primary air inlet regulates the air under the grate
(1).
The secondary air inlet regulates the air for the glass
(air wash) (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 burn at a low setting frequently, tar and
creosote may be deposited in the flue. Tar and
creosote are highly combustible substances.
Thicker layers of these substances may catch
fire if the temperature in the flue increases sud-
denly. By allowing the fire to burn very
intensely regularly, layers of tar and creosote
will disappear.
Low intensity fires can also cause tar deposits
on the stove window and door.
When the outside temperature is mild, it is bet-
ter 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 using the air vent.
The 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.
Topping up with a few logs regularly is better than
adding many logs in one go.
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 sub-
stances 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 ash
After wood has been burnt, a relatively small amount
of ash remains. This ash bed is a good insulating layer
for the stove base plate and improves combustion. It
is a good idea to leave a thin layer of ash on the stove
base plate.
The flow of air through the fire plate must not be
obstructed, however, and no ash may be allowed to
accumulate behind a cast-iron inner plate. Remove
the excess ash regularly.
09-20021-097
21
1. Open the door of the appliance.
2. Use the scraper supplied to sweep the excess ash
into the ash pan.
3. Using the glove supplied, remove the ash pan and
empty it.
4. Replace the ash pan and 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.
Resolving problems
Refer to the appendix "Diagnostic diagram" to resolve
any problems in using the appliance.

14 Subject to change because of technical improvements.
Maintenance
Follow the maintenance instructions in this chapter to
keep the appliance in good condition.
Flue
In many countries, you are required by law to have
your chimney checked and maintained.
At the start of the heating season: have the chim-
ney swept by a recognised chimney sweep.
During the heating season and after the chimney
has not been used for a long time: have the chim-
ney checked for soot.
At the end of the heating season: close off the chim-
ney and plug with newspaper.
Cleaning and other regularly
maintenance
Do not clean the appliance when it is still
warm.
Clean the exterior of the appliance with a dry lint-
free cloth.
You can clean the appliance interior thoroughly at the
end of the heating season:
If necessary, first remove the fire-resistant inner
plates. See the chapter "Installation" for instruc-
tions 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 that
are subject to wear and tear. Vermiculite inner plates
are fragile. Do not knock the inner plates with logs.
Check the fire-resistant inner plates frequently and
replace them when necessary.
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 sur-
roundings and this may cause the plate to warp
or crack.
Never use the appliance without the fire-res-
istant inner plates.
Cleaning the 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 tis-
sue.
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 appliance again.
Ensure that no stove glass cleaner runs
between the glass and the cast-iron door.
Enamelled stove maintenance
Never clean the appliance while it is still hot. The
most effective way to clean the enamelled surface of
the stove is with a mild green soap and lukewarm
water. Use as little water as possible, rub the surface
dry and prevent the formation of rust. Wire wool or
other abrasives should never be used. Never place a
kettle directly onto an enamelled stove; use a stand to
prevent damage. Attention: Do not allow aggressive
acidic products to get onto enamelled components.

Subject to change because of technical improvements. 15
Lubrication
Although cast-iron is slightly self-lubricating, you will
still need to lubricate moving parts frequently.
Lubricate the moving parts (such as guide sys-
tems,hinge pins, latches and air slides) with heat
resistant grease that is available in the specialist
trade.
Touching up damaged paint
Small areas of damaged paint finish can be touched-
up with a spray can of special heat-resistant paint,
available from your supplier.
Touching up the enamelled surface
Enamelling is a process carried out by traditional meth-
ods, meaning that it is possible that small colour dif-
ferences and damage may occur. The appliances
undergo a visual inspection in the factory, that is to
say, the inspector looks at the surface for a period of
10 seconds from a distance of 1 metre.
Any damage that does not stand out is regarded as
OK. A special heat-resistant paint is supplied with the
appliance to touch up any minor damage caused dur-
ing transport.
Apply the heat-resistant paint in thin layers and leave
to dry well before using the appliance.
Some enamel colours are temperature-sensitive. It
can happen that the colour changes during use.
The original colour will return after the appliance
has cooled down.
If enamelled surfaces become very hot, hairline
cracks can occur. This is a normal phenomenon
and has no impact on the functioning of the stove.
Ensure that the stove is not overburdened. If it
does become overburdened then the surface
gets very hot possibly resulting in lasting dam-
age to the enamel.
Checking the seal
Check whether the door sealing rope is still in good
condition and works well. The sealing rope is sub-
ject 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 appliance, as any moisture in the sealant
will form bubbles, resulting in a new air leak.
Adjust door closing
Check if the door closes properly. If required, the clos-
ing of the door can be set looser or tighter by adjusting
the distance between the locking cam and the door.
Proceed as follows:
1. Open the door. The locking cam (2) is now freely
accessible; see next figure.
2. Unscrew the two screws (1) with which the lock-
ing cam is attached.
3. By removing the packing plate (3) behind the lock-
ing cam (2), the door closes more tightly. If the
door closes too tightly then insert an additional
packing plate behind the locking cam.
4. Tighten the two screws and check the closing of
the door once again.

Replacing the glass
If the glass in the appliance is broken or
cracked, it must be replaced before the stove
is used again.
Proceed as follows:
1. Unscrew the four glass fixings with parts (3) and
(4) and remove the glass (2), see following figure.
2. Check the glass seal and, if necessary, fit a new
sealing rope.
3. Place the new glass in the grove and tighten the
glass fixings.
