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 in­stalled, 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.

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 ap­pliance.

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-commen­ded.

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.

highest point of the roof
with a distance of 3 m.

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.

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 mid­dle.

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.

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
