Foreword
The Installation Manual and Operators Instructions must accompany this appliance. As well
as instructions for installation and information about use, you will also nd advice concerning
safety and maintenance.
Please read this booklet carefully before installation and before ring the unit.
Save this booklet and pass to any subsequent user who can also prot by it.
Introduction
Your DOVRE purchase has made you the owner of a high quality product that symbolizes
a new generation of energy-saving and ecologically safe heaters, producing convection heat
as well as radiant heat with optimum efciency. Through the application 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 re blazing
in the stove. Our heaters are produced in accordance with ISO 9002, using state-of-the-art
production means. In the unlikely event of a malfunction, you can always rely on DOVRE’s
after-sales service. This heater is designed to be installed in a living room and to be hermeti-
cally connected to a ue (chimney).
If the stove is professionally installed, connected to a well-functioning chimney and suf-
ciently 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 manufacturer cannot
be held liable for problems caused by faulty installation.
Safety
The heating unit is best installed, commissioned, and checked by a competent installer 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 re in the stove with the highest possible intensity right after it is in-
stalled, so as to cure the heat-resistant paint nish. 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 instructions in the
chapter concerned.
In case of a chimney re, immediately close all air intake vents of the appliance and alert the
reman.
Broken glass should be replaced before using the heater again.
The stove is specically designed for burning certain kinds of fuels. In the technical speci-
cations under cover you can nd 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.
29

Installation guideline
Preparatory measures
The replace should be hermetically connected to a well-functioning chimney, sufciently
enclosed to keep combustible materials (oor and walls) at a distance, and should be installed
in a room with sufcient ventilation.
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 re department and/or an insurance company about specic demands
or regulations.
Please read the technical specications under cover in this manual before installing the ap-
pliance.
The chimney
The chimney (the ue) has a double function:
It draws air, that is necessary for good combustion, into the stove.
It functions as an exhaust pipe for combustion gases via thermal or natural draught. Ther-
mal draught is caused by the difference in heat between the air in- and outside the ue.
The heated air in the ue is lighter than the colder air outside the ue and consequently
rises up, along with the combustion gases. Natural 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 specic usage. You should consider an expert’s opinion on
this matter.
The chimney should meet the following conditions:
The ue should be made of reproof material. Ceramic or stainless steel is re-commen-
ded.
The chimney should be airtight and thoroughly cleaned and should guarantee a sufcient
draught (a draught or negative pressure of 15 to 20 Pa is ideal under normal circumstan-
ces).
It should run as vertically as possible. Changes in direction or horizontal segments will
disrupt the smoke ow and may cause soot to cumulate inside the ue (and clog the
ue!).
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
specication under cover. Larger dimensions can be used if the ue is well insulated.

The ue’s diameter should be the same throughout its whole length. Wider, or especially
narrower segments will disrupt the smoke ow and are best avoided. The same is true
for a cover plate or exhaust hood on top of the chimney. The exhaust hood must not nar-
row the chimney’s outlet and should be designed in a way that wind will not hinder, but
promote the smoke ow.
Especially if the ue runs through unheated rooms or outside the house, further insula-
tion is necessary. Metal chimneys, or parts of the chimney outside heated rooms should
always have double-walled, insulated ues. The part of the chimney 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 buildings or trees, the chimney should be higher.

Ventilation
The burning of wood, charcoal or gas involves oxygen consumption. It is of the utmost impor-
tance that the room in which the stove is installed should be sufciently ventilated.
Insufcient ventilation may disrupt the combustion process and cause the smoke ow through
the chimney to be interrupted, which may lead to smoke emissions into the room.
If necessary, you can install a ventilation grille to provide a constant ow of fresh air in the
room. This precaution is particularly necessary in well-insulated rooms with mechanical ven-
tilation.
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.
If your appliance is provided with a connection kit (available as an option) for supplying the
combustion air from outside the room, you do not need to provide your appliance with any
extra air intake.
Ensure that there is sufcient ventilation in the area from which you draw the air.

Floor, walls
A safe distance should be kept between the stove and combustible materials such as wooden
walls and furniture. Fot this distance see annex.
The appliance shall be installed on oors with an adequate load-bearing capacity.
Combustible oors require sufcient protection against radiant heat by means of a reproof
protective plate. Rugs and carpets must be kept at a distance of at least eighty centimetres
from the re.
32

Preparation
Please inspect the replace for damage caused during transport immediately after delivery and
notify your distributor in case there are any defects. Do not put the appliance into operation
in the meantime.
In order to avoid damaging the replace during installation and to make its handling easier,
it is recommended to remove previously all loose parts (re-resistant bricks, grille, ashtray,
...) from the stove. Note the location of those parts while removing them, so that you have no
difculties in re-assembling the parts later on.
Opening and closing the door
The door can be opened and closed by means of the handle in the mid-
dle.
The smoke outlet
Your stove is suitable for two connections: a top or a rear connection.
Upon supply, the top
and rear exhausts have
been left open. Depen-
ding on the position
chosen, one opening
can be covered with
the blanking plate sup-
plied; the other one can
be equipped with the
connection collar supp-
lied (see picture). Use
the xings supplied and
be sure to tightly seal
the connection collar
and the blanking plate
to the stove by means
of the kit or paste sup-
plied.
33

Assembling the bafe plate
Assembling outside combustion air connection back or bottom (if necessary)
You can connect the external air supply from either beneath or behind the base (diameter 100
mm).
The air intake in the base plate must be closed
with the cast iron cover plates supplied.
Use the plastic sealing ring supp-
lied to seal the base

Finishing
When the stove is placed in the nal position and hermetically connected to the chimney, you
can replace all of the loose parts.
Your stove is now ready for use.
Attention: never light a re with the inner plates or refractory stones removed.
Packaging materials
Packaging materials should be disposed of in a responsible way and in accordance with go-
vernmental regulations.

Instructions for use
Fuel
The only suitable fuels for this stove are wood, brown coal briquettes and charcoal. No other
fuels are allowed to be burnt, as they can inict serious damage to your stove.
Do not burn any treated wood either, such as scrap wood, dyed wood, impregnated or pre-
served wood, plywood or chipboard. The fumes of these, as of synthetic materials, old papers
and household waste, are highly polluting for both your stove and your chimney, and for the
environment. They also could cause chimney res.
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 percent 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 smel-
ling gases to be released and a thick layer of tar will deposit on the stove panels and in the
chimney.
Brown coal briquettes
Brown coal briquettes burn in more or less the same way as wood 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 deter-
mined. For instance anthracite “A” has to contain less than 10% of volatile substances, anthra-
cite “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 content is re-
commended. A combustible with a high ash content has a lower net heating value. Moreover,
the ashes have to be removed more frequently and the re will go out faster. The recommen-
ded calibre is 12/22 or 20/30.
Air supply adjustment
For the supply of combustion air, the stove is equipped with two vents which are adjustable
by means of two levers at the bottom of the front panel of the stove (see picture). Through
special air ducts, primary air (1) is led to the bottom of the combustion chamber. Secondary
air (2) reaches the top of the glass panel.
32

Lighting a re
In order to create sufcient draught and to prevent smoke from emanating into your living
room, the chimney should be warm enough before lighting a re. A cold chimney can be hea-
ted up by lighting a ball of paper above the re plate.
To kindle the re in the stove you can use paper and/or relighters and small pieces of wood.
Slightly open the door and pull the air slides wide open.
It is important that the kindled re should burn intensely. You can then throw larger pieces of
wood onto the re, and close the doors. When the re has eventually stabilized and is glowing
enough, you can put the logs or the brown coal briquettes or the coals on the re.
Burning wood
The best way to control the re is to completely close the lower air slide, which you use to
get the re started, and to regulate the air supply with the upper air slide only. In case the air
supply through the upper slide seems insufcient, or if you would like to fan the re, you can
partially open the lower air slide for a while.
Add extra fuel when necessary. Never add too much fuel. It is best to ll the stove for one third
and to top it up on a regular basis.
Always open the lling door slowly. Before lling up, the charcoal bed should be carefully
spread open. If necessary you can open the lower air slide for a while.
Open stacking will make the logs burn very intensely, as the oxygen can easily reach every
part of the re. This method of stacking is applied when burning wood for a short while.
Compact stacking will make the re burn slower, as the air can only reach the outer parts of
the re. This stacking method is best used when burning for a longer while.
33

Low intensity res cause tar
and creosote to deposit in
the chimney after a long pe-
riod of time. Tar and creo-
sote are highly combustible
substances. Thicker layers
of these substances might
catch re when the tempe-
rature in the chimney incre-
ases suddenly and steeply.
Therefore it is necessary for
the re to regularly burn very intensely, so that thin layers of tar and creosote immediately
disappear.
Low intensity res also cause tar to deposit on the stove panels 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.
Burning coal
FOR BURNING WITH COAL, THE AIR INTAKE ABOVE THE DOOR (2) (= SECON-
DARY AIR INTAKE) MUST BE CLOSED AT ALL TIMES.
When the ignition re has sufciently stabilized and when there is a sufcient blaze, then a
scoop of coal can be added to the re.
Use the front door when lling. Once the coals have ignited, the addition of coals can be
completed. Make sure that you do not put out the re by adding too much coal at once. After
the coals have been burning well for some time, adjust the level of the primary air-inlet. Just
prior to relling, open the primary air-inlet completely. Now use the shaking grate and shake
until glowing bits fall into the ash drawer. After that, add coal.
After a couple of minutes, adjust the primary air-inlet to the desired position. Add a maxi-
mum amount of coal until you can just make out the glow of the previous lling.
When the re basket or the cast-iron plate ns are red-hot, you are heating too intensely.
Low heating (for devices suitable for continuous use)
To use the advice as a “continuous re”, you can select the primary ans secondary air scoops
in such a way you get the right burning speed. Always make sure there’s enough glow on the
heating bottom.
34

Ash removal
With the included “cold” hand, the shaking
grate can be moved. The ash drawer must be
timely emptied. The ashes must not obstruct
the passage of the combustion airow, and in
no case should the ash touch the underside of
the grating. If not, the grating will overheat and
will be damaged.
Relatively speaking, burning wood produces
little ash and it will not be necessary to remove
it each time daily.
Extinguishing the re
Stop fuelling the re and let it burn out.
Damping a re by closing the air slides involves the release of noxious gases. You should let
the re burn out and keep an eye on it as long as it is still glowing.
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 replace under these weather conditions.
35

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 supply you
with the correct spray product.
During the rst 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 tho-
roughly clean the stove on the inside.
If necessary, replace the sealing ropes and use re cement to ll up possible leaks. Remove the
replate 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. Checking 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.
