1.Introduction
Your DOVRE purchase has made you the owner of a high quality product that sym-
bolizes a new generation of energy-saving and ecologically safe heaters, producing
convection heat as well as radiant heat with optimum efficiency. Through the appli-
cation of a revolutionary combustion concept DOVRE heaters achieve astonishing
results in full compliance with strict environmental and safety norms. Also, you will
be enjoying the lovely sight of the fire blazing in the stove.
Our heaters are produced in accordance with ISO 9002, using state-of-the-art pro-
duction means.
In the unlikely event of a malfunction, you can always rely on DOVRE’s after-sales
service. Any unauthorised modific ation of the appliance is forbidden and use only
replacement parts recommended by the manufacturerr.
This heater is designed to be installed in a living room and to be hermetically con-
nected to a flue (chimney).
If the stove is professionally installed, connected to a well-functioning chimney and
sufficiently ventilated, you can take the long-term and trouble-free functioning of
your heater for granted.
Please consult an expert when installing and connecting the heater. The manufac-
turer cannot be held liable for problems caused by faulty installation.
2.Safety
The heating unit is best installed, commissioned, and checked by a competent in-
staller who is aware of national and local legislation.
The heater is designed to heat a room, which means that all surfaces, including the
front glass, can get very hot (> 100 °C).
Please do not place any curtains, clothes, laundry, furniture or other combustible
materials on or near the heater.
It is advised to make a fire in the stove with the highest possible intensity right after
it is installed, so as to cure the heat-resistant paint finish. This may involve some
odour production, which will however disappear after a while.
It is necessary to maintain and regularly clean the stove and the chimney for the
stove to function safely and for a long period of time. Please follow the cleaning in-
structions in the chapter concerned.
In case of a chimney fire, immediately close all air intake vents of the appliance and
alert the fireman.
Broken glass should be replaced before using the heater again.
The stove is specifically designed for burning certain kinds of fuels. In the technical
specifications under cover you can find detailed information concerning this topic. It
is absolutely prohibited to burn fuels other than these, as this may damage your
heater. Moreover, it is ecologically harmful.

3.Principle
The Dovre model is designed to provide a fireplace convection system without the
need to construct a masonry convection chamber. The principle of operation is
that the cooler air from the lower part of the room is drawn under the base of the
inner cast iron unit. Warm air is produced from the inner cast iron surfaces of the
appliance and this warm air develops between the surfaces of the steel convection
case and the outer surfaces of the cast iron combustion chamber. Flexible piping
may be used to carry the warm air from the appliance to outlet grills to be located
where heat is required. This can be either in the same room as the appliance or in
other rooms even at first floor level. It is essential to ensure that the warm air
flexible pipes are allowed to rise from the appliance.
The cooler room air entering the lower level moves the warm air by convection,
and fan assistance whilst the fans are operating, to be discharged into the room
through the space at the top of the applianceor via flexible pipework.

4.Installation guideline
4.1. Preparatory measures
The fireplace should be hermetically connected to a well-functioning chimney, suffi-
ciently enclosed to keep combustible materials (floor and walls) at a distance, and
should be installed in a room with sufficientventilation.
Please inform about national or local norms and regulations concerning this subject.
Your distributor will give you the necessary advice.
You can also consult the fire department and/or an insurance company about spe-
cific demands or regulations.
Please read the technical specifications under cover in this manual before installing
the appliance.
4.1.1. The chimney
The chimney (the flue) has a double function:
•It draws air, that is necessary for good combustion, into thestove.
•It functions as an exhaust pipe for combustion gases via thermal or natural
draught. Thermal draught is caused by the difference in heat between the air in-
and outside the flue. The heated air in the flue is lighter than the colder air out-
side the flue and consequently rises up, along with the combustion gases. Natu-
ral draught is caused by environmental phenomena, such as wind.
It is prohibited to connect several heaters to one chimney (for instance the central
heating boiler), unless local or national regulations allow this.
Please check which chimney is to be used for the stove you purchased and whether
your chimney is appropriate for this specific usage. You should consider an expert's
opinion on this matter.
The chimney should meet the following conditions:
•The flue should be made of fireproof material. Ceramic or stainless steel is re-
commended.
•The chimney should be airtight and thoroughly cleaned and should guarantee a
sufficient draught (a draught or negative pressure of 15 to 20 Pa is ideal under
normal circumstances).
•It should run as vertically as possible. Changes in direction or horizontal seg-
ments will disrupt the smoke flow and may cause soot to cumulate inside the
flue (and clog the flue!).
•The chimney's inside dimensions must not be too large in order to prevent the
smoke from cooling off too much. For recommended chimney dimensions, see
the technical specification under cover. Larger dimensions can be used if the flue
is well insulated.
•The flue's diameter should be the same throughout its whole length. Wider, or
especially narrower segments will disrupt the smoke flow and are best avoided.

2020/2220/2520/2210/2510/2200/2500 6 03.27883.100
The same is true for a cover plate or exhaust hood on top of the chimney. The
exhaust hood must not narrow the chimney's outletand should be designed in a
way that wind will not hinder, but promote the smoke flow.
•Especially if the flue runs through unheated rooms or outside the house, further
insulation is necessary. Metal chimneys, or parts of the chimney outside heated
rooms should always have double-walled, insulated flues. The part of the chim-
ney outside the roof should always be insulated.
•The chimney should be high enough (at least four metres) and should end in a
zone that is clear of nearby buildings, trees or other obstacles. The rule of
thumb here is: 60 cm above the ridge of the roof. If the distance between the
ridge and the chimney measures more than three metres, see the dimensions
stipulated in the illustration below. Depending on the presence of nearby build-
ings or trees, the chimney should be higher.
4.1.2. Ventilation
The burning of wood, charcoal or gas involves oxygen consumption. It is of the ut-
most importance that the room in which the stove is installed should be sufficiently
ventilated.
Insufficient ventilation may disrupt the combustion process and cause the smoke
flow through the chimney to be interrupted, which may lead to smoke emissions
into the room. Mainly in case of a fireplace, together with the combustion gases, lots
of room air will be extracted through the chimney; that makes supply of sufficient
fresh air and ventilation extremely important.
If necessary, you can install a ventilation grille to provide a constant flow of fresh air
in the room. This precaution is particularly necessary in well-insulated rooms with
mechanicalventilation.
The DOVRE fireplace has been designed to produce most heat by means of convec-
tion. Heat is mainly transmitted through the back panel, the lateral panels, and the
smoke dome. Both the material (cast iron) and shape (increased heating surface by
means of corrugation) improve heat transmission to the surrounding air. As this air
is heated, it will rise and a natural hot air flow, i.e. convection, will develop. Up to
your choice, that hot air may be led to thesame room or to another room.
For optimal heating and leading the convection air, the airflow must not encounter
any obstacles. Hence, it is important that there is enough space between the fire-
place and the surrounding material, and that the inlet and outlet area of convection
air are sufficiently large.

2020/2220/2520/2210/2510/2200/2500 703.27883.100
Convection air may be led to arrive from both the room and outside (other room,
cellar, exterior) to the bottom side of the fireplace. In case convection air is supplied
(directly or indirectly) from outside, it may also be useful as a supply of fresh air for
combustion.
At any rate, assure proper home air management and sufficient air supply into the
room.
Ensure not to use other air-consuming appliances, such as heaters, cooking hoods,
bathroom ventilators, in the same room or in the house while the stove is burning;
or make sure to have an extra ventilation grille installed for these appliances.
4.1.3. Floor, walls
The appliance shall be installed on floors with an adequate load-bearingcapacity.
Combustible material must be sufficiently protected. The floor under the fireplace
and the walls around it must not contain electric wires.
Under the appliance
Under the appliance, any combustible material must be removed or specially
shielded by means of a 6 cm concrete slab and 10 cm insulation. The legs of the
appliance may rest directly on the concrete slab and insulation must be applied in-
between the legs.
Floor round the appliance
A floor made of combustible material must be properly shielded in the following
areas:
Front: height of the lower part of the fire chamber + 30 cm, but 60 cm at least.
Sides: height of the lower part of the fire chamber + 20 cm, but 40 cm at least.
Walls, ceiling
Combustible walls behind, next to, or above the fireplace must be shielded with at
least a 10 cm stone or brick wall and 10 cm insulation. Fireproof materials should be
covered with at least 6 cm insulation.

4.1.4. Combustible material round the fireplace
Within the radiation area of the fireplace
Assure a distance of at least 80 cm between the opening of the fireplace and com-
bustible material. That distance may be reduced to 40 cm if the combustible mate-
rial is sufficiently shielded and well ventilated.
Outside the radiation area of the fireplace
Assure a distance of at least 5 cm between the mantle
built around the fireplace and combustible material. A
small surface contact between combustible material and
the mantle (e.g. wall cladding) is allowed if the mantle of
the fireplace is sufficiently insulated.
A wooden ornamental rafter must not be installed within
the radiation area of the fire. Outside the radiation area,
there must always be a ventilation gap of 1 cm all around
to prevent heat from building up (see picture).
No combustible material must be present within 50 cm from the convection outlet
areas.
4.2. Preparation
Please inspect the fireplace for damage caused during transport immediately after
delivery and notify your distributor in case there are any defects. Do not put the ap-
pliance into operation in the meantime.
In order to avoid damaging the fireplace during installation and to make its handling
easier, it is recommended to remove previously all loose parts (fire-resistant bricks,
grille, ashtray, ...) from the stove. Note the location of those parts while removing
them, so that you have no difficulties in re-assembling the parts later on.
4.2.1. Changing the direction of the door-opening
It is possible to change the direction of the door open-
ing. On each side you have already the system.
4.2.2. Removing the clapet
You can remove the clapet and the tige by holding it upward and moving it a little
over the baffle-plate. When you loose the bolt in the topplate you can remove the
baffle plate.

4.2.3. Fitting frame surround
The decorative frames, 3 and 4 sides versions are fitted to the applaice after installa-
tion. Ensure that sufficient space is allowed to both sides of the recess.

4.2.4. Assembling the “cold handle”
Assemble the different parts of the handle, I.e. a screw
M8x50, a wooden handle and a nut, as indicated on thes-
ketch.
4.2.5. Electrical connection
For protection, the unit must always be connected to power. The appliance is sup-
plied with a speed control to vary the running speed of the fans. This can be left trail-
ing or fitted o the wall mounting supplied.

2020/2220/2520/2210/2510/2200/2500 11 03.27883.100
4.3. Installation
The appliance is designed to be built into a new or existing chimney breast installa-
tion to provide space heating by radiant an convected heat.
4.3.1. To be built into a new chimney
Build the new fire place around the appliance ensuring that no materials are built
onto the appliance. Before constructing the fireplace facing wall (section between top
of appliance and underside of raft lintel, fit a support lintel supported by the side
walls and build the face wall using lightweight insulated building blocks backed with
insulated panels.
Never build directly onto the appliance.
If flexible warm air ducts are to be used, install air grills at the outlet locations to
allow passage of warm air to the specific area.
Where the fireplace backs onto another room or is in the corner of a room, backing
onto two rooms, grills van be fitted in the adjoining room or rooms.
Never use grills made from plastic or other combustible materials.
Ensure that the weight of the main chimney or chimney flue liners is not directly sup-
ported by the appliance. Flue liners must be supported independently of the appli-
ance.
4.3.2. To be built in a existing chimney
The recess should be formed using an appropriately designed raft lintel to support
the existing brickwork structure and chimney. The minimum clearance between the
back of the appliance and the rear should be 1,5 cm. It is recommended to fix insu-
lating panels to the sides, back and top of the appliance.
Never allow marble, granite or masonry to be in direct contact with the metal outer
box of the appliance. Always use insulation.
Prepare the opening ensuring that adequate support is provided for thechimney and
existing brickwork structure. Ensure that enough height is allowed to adequately
connect the appliance to the main chimney. If necessary, construct a raft lintel to
form the top of the recess to support the chimney and surrounding masonry. This
could be pre-formed with a minimum diameter 150 mm clearance hole incorporated
for the connecting minimum diameter 150 mm flue pipe.
If the recess is too wide, use insulated building blocks to reduce the width.
Clean thouroughly the floor, wall and top of the recess.
Stand the appliance in the recess and use a spirit level to ensure the unit is level and
plumb.
If an exiting masonry is installed, the appliance should be connected to the chimney
using minimum diameter 150 mm, stainless steel pipe. It is important to ensure that
the connection to the chimney is carried out in such a way that any soot particles are
allowed to fall un-hindered back into the appliance.
Ensure that the weight of the main chimney or chimney flue liners is not directly sup-
ported by the appliance. Flue liners must be supported independently of the appli-
ance.

2020/2220/2520/2210/2510/2200/2500 12 03.27883.100
4.4. Finishing
When the appliance is installed in the right place, its connection with the chim-
ney made airtight, and the masonry mantle completely mounted, all loose parts
are installed in the appliance.
Your fireplace is now ready to be used.
Depending on the materials used for mounting, it is recommended to wait for
some time until all masonry is dry before lighting a fire.
Attention: never light a fire with the inner plates or refractory stones re-
moved.
4.5. Packaging materials
Packaging materials should be disposed of in a responsible way and in accor-
dance with governmental regulations.

5.Instructions for use
5.1. Fuel
The only suitable fuels for this stove are wood, brown coal briquettes and charcoal
(when you use a coal-basket). No other fuels are allowed to be burnt, as they can
inflict serious damage to your stove.
Do not burn any treated wood either, such as scrap wood, dyed wood, impregnated
or preserved wood, plywood or chipboard. The fumes of these, as of synthetic mate-
rials, old papers and household waste, are highly polluting for both your stove and
your chimney, and for the environment. Theyalsocouldcause chimney fires.
Wood
Hard woods, such as oak, birch-and fruit-trees, are the ideal fuels for your stove.
The wood must have dried for at least two years in a covered and well-ventilated
place. Split logs will dry faster. Dry wood should contain no more than twenty per-
cent moisture.
Wet logs are unsuitable for burning, as they do not produce enough heat and all of
the energy is lost in the process of evaporation. Moreover, the burning of wet wood
causes badly smelling gases to be released and a thick layer of tar will deposit on
the stove panels and in the chimney.
Browncoal briquettes
Brown coal briquettes burn in more or less the same way aswood does. You should
only burn briquettes on a bed of charcoal in your stove.
Charcoal
There are several categories of anthracite coal. Some characteristics may be legally
determined. For instance anthracite “A” has to contain less than 10% of volatile sub-
stances, anthracite “B” less than 12%. The ash content may range from 3 to 13%.
For a good operation of your appliance, the use of anthracite “A” with a low ash con-
tent is recommended. A combustible with a high ash content has a lower net heating
value. Moreover, the ashes have to be removed more frequently and the fire will go
out faster. The recommended calibre is 12/22 or 20/30.
5.2. Lighting a fire
In order to create sufficient draught and to prevent smoke from being emitted into
the room, the chimney should be warm enough before lighting a fire. A cold chim-
ney can be heated up by lighting a ball of paper above the fire plate.
To kindle the fire in the stove you can use paper and/or firelighters and small pieces
of wood.
Slightly open the door.
It is important that the kindled fire should burn intensely. You can then throw larger
pieces of wood onto the fire, and close the doors. When the fire has stabilized and is

2020/2220/2520/2210/2510/2200/2500 16 03.27883.100
glowing enough, you can put the logs, the charcoal or the brown coal briquettes on
the fire.
5.3. Burning wood
Always keep the stove doors tightly closed. Never let the doors open when the fire is
burning.
Add extra fuel when necessary. Never add too much fuel. It is best to fill the stove
for one third and to top it up on a regular basis.
Always open the filling door slowly and for a short space of time. Before filling up,
the charcoal bed should be carefully spread open. Check whether the coals are glow-
ing enough just behind the log retainer, so that the added fuel will immediately
catch fire. If necessary you can open the lowerair slide for a while.
Open stacking will make the logs burn very intensely, as the oxygen can easily reach
every part of the fire. This method of stacking is applied when burning wood for a
short while. Compact stacking
will make the fire burn slower, as
the air can only reach the outer
parts of the fire. This stacking
method is best used when burn-
ing for a longer while.
Low intensity fires cause tar and
creosote to deposit in the chim-
ney after a long period of time.
Tar and creosote are highly com-
bustible substances. Thicker lay-
ers of these substances might
catch fire when the temperature
in the chimney increases sud-
denly and steeply. Therefore it is necessary for the fire to regularly burn very in-
tensely, so that thin layers of tar and creosote immediately disappear.
Low intensity fires also cause tar to deposit on the stove panes and doors.
When it is not too cold outside it is better to let the stove burn intensely for just a
few hours a day.
5.4. Burning coal
You need a coal-basket for burning coal.
WHEN BURNING CHARCOAL THE AIR SLIDE ABOVE
MUST ALWAYS BE KEPT CLOSED.
As soon as the fire is sufficiently stable and there is
enough glow, the first shovel of coals can be put onto
the fire. Complete the filling once the coals have
caught fire. Make sure you do not quench the fire by
open stacking compact stacking

2020/2220/2520/2210/2510/2200/2500 17 03.27883.100
Before adding some extra coals, use the shaker grate or the supplied shovel, and shake
till the glowing parts fall into the ash plate; then add the coals.
After a few minutes, add some more coals until you can only see the glow of the previous
filling.
When the fire basket or the cast-iron plate fins are red-hot, you are heating too in-
tensely.
5.5. Ash removal
If your fireplace is equipped with an ashtray (optional), it
must be emptied before the ashes reach the lower edge of
the combustion grid. With the cold handle supplied, you can
tilt the grid upwards and remove the ashtray fromthe device.
Relatively speaking, burning wood produces little ash and it
will not be necessary to remove it each time daily.Moreover,
wood burns better on a bed of ash.
5.6. Extinguishing the fire
Stop fuelling the fire and let it burn out.
You should let the fire burn out and keep an eye on it as long as it is still glowing.
5.7. Weather conditions
Attention!
Mist and heavy fog will block the chimney's smoke outlet and may lead to smoke
emissions into the living room.
It is best not to use the fireplace under these weather conditions.

2020/2220/2520/2210/2510/2200/2500 18 03.27883.100
6.Maintenance
It takes only little effort to keep your appliance in good condition.
Regularly check whether the sealing cord still closes the doors tightly enough.
Minor paint damage can be touched up with a can of spray paint. Your dealer can
supplyyou with the correct spray product.
During the first use after repainting your unit might give off some slight odour.
However, this will disappear quickly.
The glass can be cleaned with a number of glass cleaning products available on the
market. Your installer can also supply you with appropriate products. However,
never use abrasive or corrosive cleaning products.
At the end of the heating season, seal off the chimney with a ball of paper. You can
then thoroughly clean the stove on the inside.
If necessary, replace the sealing ropes and use fire cement to fill up possible leaks.
Remove the fireplate for better and more thorough cleaning.
To remove the doors, disassemble the hinges as shown.
You should have your chimney swept by an expert before the heating season begins.
It is useful to check the chimney for soot during the heating season as well. Check-
ing and maintaining the chimney is a statutory requirement.
When all of the above advice is heeded, you will be able to fully enjoy your stove.
