1. 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 efficiency. 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 fire 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 hermetically connected 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 manufacturer cannot be held liable for problems caused by faulty installation.
2. 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 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 instructions 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 ce rtain 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 fireplace should be hermetically connected to a well-functioning chimney, sufficiently enclosed to keep combustible materials (floor and walls) at a distance, and
should be installed in a room with sufficient 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 fire department and/or an insurance company about specific demands or regulations.
Please read the technical specifications under cover in this manual before installing
the appliance.
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 ou tside the flue 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 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.
2900 4 03.27896.100
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 outlet and 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 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.
3.1.2. Ventilation
The burning of wood, charcoal or gas involves oxygen consumption. It is of the utmost 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
mechanical ventilation.
The DOVRE fireplace has been designed to produce most heat by means of convection. 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 the same 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 fireplace and the surrounding material, and that the inlet and outlet area of convection
air are sufficiently large.

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.
3.1.3. Floor, walls
Combustible material must be sufficiently protected. The floor under the fireplace and the
walls around it must not contain elec tric wires.
The appliance shall be installed on floors with
an adequate load-bearing capacity.
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.
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.

3.2. 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 appliance 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.
See picture 1 for how to handle the aplliance for transport.
See picture 2 for loosing the screws for tansport-securty.
3.2.1. Assembly of the legs (see picture 3)
Fix the adjustment bolts under the legs. These will allow to adjust the fireplace
level.
3.2.2. Assembly of the smoke dome and of the flue collar
The smoke dome must be fixed to the top of the device and attached by means of the clamps supplied.
Assure proper sealing by means of the kit or paste supplied.
It is recommended to install the smoke dome with its
exhaust backwards. In case of proper draft, it may be
turned up to 90° to the left or to the right if required
for installation. In case of lower draft, an angle of
maximum 60° is recommended.
The flue collar can be installed either horizontally or
vertically. Fix the flue collar on the smoke dome. Assure proper sealing with kit or paste.
3.1.4. 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 combustible material. That distance may be reduced to 40 cm if the combustible material 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.

3.3. Installation of the fireplace
3.3.1. Positioning and connection
Put the fireplace at proper height. Make sure that it is stable and level and that the
side panels are perpendic ular to the bottom
plate. Put the fireplace far
enough from the walls, so
that minimum 5 cm of free
air passage remains between the back of the fireplace and the wall after
adding the necessary insulation.
Make an airtight connection between fireplace and
chimney, according to
good pra ctice.
Before further installation of the fireplace, check for sufficient draft in the chimney
and for proper connection between the smoke duct and the appliance.
For that purpose, you can light a small intense fire with paper and small dry kindle.
In case of a brick smoke duct, wait until the duct is dry enough.
3.3.2. Mounting
Start with the masonry round the base of the fireplace. In that
masonry, the air supply grids (optional) will be installed. Minimum air supply opening is 250 cm². The grids may be installed
on all sides.
It is important that air flows freely into the convection chamber. If you use an air vent (to convey outside air into the convection chamber), remember to build in the adjustment knob.
It is recommended to cover the inner side of the convection
chamber with extra reflecting insulation material. That prevents loss of heat radiation to outside walls or adjacent rooms, as well as deterioration of any inside wall insulation.
Make sure that the doors of the hearth move freely over the plate in front of the fireplace.
Continue building the chimney up to the smoke dome. Assure a gap of at least 2
mm between the fireplace and the masonry to allow for dilatation of the fireplace. If
necessary, use heat-resistant strips.
Upper structure support
The masonry over the fireplace must not rest on the fireplace. That is why a support
is used. Between the steel support and the smoke dome, you must leave a free
space of at least 3 mm. That will prevent tensions in the material that might tear the
upper structure. The steel support may rest on the side structure or be attached to
the wall by means of threaded rods.
