Foreword
The Installation Manual and Operators Instructions must accompany this appliance.
As well as instructions for installation and information about use, you will also find
advice concerning safety and maintenance.
Please read this booklet carefully before installation and before firing the unit.
Save this booklet and pass to any subsequent user who can also profit by it.
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 sight of the fire blazing in the stove.
Our heaters are produced in accordance with ISO 9002, using state-of-the-art pro-
duction methods.
In the unlikely event of a malfunction, you can always rely on DOVRE’s after-sales
service. Any unauthorised modification of the appliance is forbidden and use only
replacement parts recommended by the manufacturer.
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.
2.Safety
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.Installation guideline
3.1. Preparatory measures
The stove 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
thestove.
3.1.1. The chimney
The chimney (the flue) 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. 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 accumulate inside the
flue (and clog the flue!).
•The chimney's internal dimensions must not be too large in order to prevent the
fumes 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.
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 outlet and should be designed in a

640CB -760CB 5 03.27999.000
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.
3.1.2. 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.
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.
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 grill installed for these appliances.
If your stove is equipped with the (optional) connection set to feed combustion air
from outside the room, you do not need an additional air supply. However, ensure
sufficientventilation of the room from which you supply air.
3.1.3. Floor, walls
A safe distance should be kept between the stove and combustible materials such as
wooden walls and furniture. If you purchased a freestanding stove, this distance
should be at least fortycentimetres.
The appliance shall be installed on floors with an adequate load-bearing capacity.
Combustible floors require sufficient protection against radiant heat by means of a
fireproof protective plate. Rugs and carpets must be kept at a distance of at least
eighty centimetres from the fire.

3.2. Preparing the stove
Please inspect the stove for damage caused during transport immediately after deliv-
ery and notify your distributor in case there are any defects. Do not put the stove
into operation in the meantime.
In order to avoid damaging the stove during installation and to make handling of the
stove easier, it is recommended to remove previously all loose parts (fire-resistant
bricks, 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.
The stove will be supplied with the following parts:
•A connection collar with fixings
•A blanking plate with fixings
•A “cold handle” for the door
•A “cold handle” to pull out the ashtray
•A scraper for the ashes
3.2.1. Smokeoutlet
Your stove is suitable for two
connections: a top or a rear
connection.
Upon supply, the top and rear
exhausts have been left open.
Depending on the position cho-
sen, one opening can be cov-
ered with the blanking plate
supplied (2); the other one can
be equipped with the connec-
tion collar supplied (1) (see pic-
ture). Use the fixings supplied
and be sure to tightly seal the
connection collar and the blank-
ing plate to the stove by means
of the kit or paste supplied.
In order to make the connection
easier, the top plate (3) may
simply be removed from the
stove and replaced afterwards.
The blanking plate (2) is de-
signed such that, in case of rear
mounting, it seems to be an
integral part of the top plate; in
case of top mounting, it can
cover the rear opening without
disturbing the outer appearance.

3.2.2. 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 the
sketch.
3.3. Finishing
When the stove is placed in the final position and hermeti-
cally connected to the chimney, you can replace all of the loose parts.
Your stove is now ready for use.
Attention: never light a fire with the inner plates or refractory stones removed.
3.4. Packaging materials
Packaging materials should be disposed of in a responsible way and in accordance
with governmental regulations.
4.Instructions for use
4.1. Fuel
The only suitable fuel for this stove is wood. No other fuels are allowed to be burnt,
as they can inflict serious damage to your stove.
Do not burn any treated wood 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, your chim-
ney, and for the environment. They also could cause 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.

640CB -760CB 8 03.27999.000
4.2. Air supply adjustment
For the supply of combustion air, the stove is equipped with three vents at the rear,
of which two 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 bot-
tom of the combustion chamber and passes through the ash removal port. Secon-
dary air (2) reaches the top of the glass panel. Permanent air supply to the rear side
of the combustion chamber (3) under the flame plate assures perfect post-
combustion.
4.3. 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 and turn the air slides wide open.
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 eventually stabi-
lized and is glowing enough, you can put the logs or the brown coal briquettes on
the fire.
4.4. Burning wood
The best way to control the fire is to completely close the primary air slide, which
you use to get the fire started, and to regulate the air supply with the secondary air
slide only. In case the air supply through the secondary air slide seems insufficient,
or if you would like to fan the fire, you can partially open the primary air slide for a
while.
Always keep the stove doors tightly closed. Never leave the doors open when the fire
is burning.

640CB -760CB 9 03.27999.000
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 at a 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 primary air slide for a while.
Open stacking will make the logs burn
very intensely, as the oxygen can eas-
ily reach every part of the fire. This
method of stacking is applied when
burning wood for a short while. Com-
pact 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 burning for
a longer while.
Low intensity fires cause tar and creosote to deposit in the chimney after a long pe-
riod of time. Tar and creosote are highly combustible substances. Thicker layers of
these substances might catch fire when the temperature in the chimney increases
suddenly and steeply. Therefore it is necessary for the fire to regularly burn very
intensely, so that thin layers of tar and creosote immediately disappear.
Low intensity fires 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.
4.5. Low heating (for devices suitable for continuous use)
To use the device as a 'continuous fire', you can select the primary and secondary air
scoops in such a way you get the right burning speed. Always make sure there's
enough glow on the heating bottom.
4.6. Ash removal
The bottom of the fire compartment is equipped with a port to eliminate the ashes.
open stacking compact stacking

640CB -760CB 10 03.27999.000
5. Maintenance
It takes little effort to keep your stove in good condition.
Regularly check whether the sealing cord still closes the doors tightly enough.
The painted or enamelled cast iron mantle can be cleaned with a moist, soft cloth,
when it is almost cold. Make sure no aggressive, acid products get in touch with
enamelled parts.
Minor paint damage can be touched up with a can of spray paint. Your dealer can
supply you with the correct spray product. For enamel damage, small repair kits of
appropriatecolour are available from your dealer.
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 from
your dealer. Your installer can also supply you with appropriate products. However,
never use abrasive or corrosive cleaning products.
Toclean the air ducts, you may remove the top plate; it lies loosely on the stove and
is not attached with screws or bolts.
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 fire plate for better and more thorough cleaning. Eventually remove the
refractory stones first.
You should have your chimney swept by an expert before the heating season begins.
It is also useful to check the chimney for soot during the heating season and to
check for blockage of the chimney flue prior to re-lighting after a prolonged shut
down period. 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.
Open the port (see picture) and sweep the redundant ashes into the ashtray by
means of the scraper. With the "cold handle", you can pull the ashtray from the stove
(see picture).
Relatively speaking, burning wood produces little ash and it will not be necessary to
remove it each time daily. The ash in the cavities between the ribs of the fire plate
does not need to be removed, since wood burns better on a bed of ash.
4.7. Extinguishing the fire
Stop fuelling the fire and let it burn out.
Damping a fire by closing the air slides involves the release of noxious gases. You
should let the fire burn out and keep an eye on it as long as it is still glowing.
4.8. Weather conditions
Attention!
Mist and heavy fog will block the chimney's fume outlet and may lead to smoke
emission into the living room.
It is best not to use the stove under these weather conditions.
