4.2. In case of fuel gas smell appearance
Turn off the fireplace
Open windows and doors
Seek instructions or help from a qualified person or
your serviceman
In case that the chimney has caught fire (which can be
diagnosed by some of the following ways: visually - there can
be seen glittering sparks or flame on the upper output side of
the chimney, by hearing –muffled roar, blare or rumble
inside the chimney, and by touching only if it is possible
because of a danger of burn –unusually high temperature of
the chimney flue) stop the fireplace operation. All openings
on the fireplace (burner's door) must be closed and sealed.
Possible additional openings on the chimney (door for
cleaning and possible spare openings) should also be closed
and made sure they will not self-open because of the
increased pressure of the gases in the chimney. During
burning and later after self quenching and cooling the
chimney should be constantly monitored and all noticed
critical spots should be controlled. It is strictly forbidden to
cool the chimney directly by water in order to put it out since
by doing that we will certainly cause a chimney explosion and
fire in the building. It is allowed, in case of need, to cool
endangered objects in the vicinity of the burning chimney if
you think that they can be caught by fire. Beside all these
safety measures you should also inform a fireman on duty of
the competent fire station by dialling number 123.

5.4. Fireplace description
The fireplace is constructed so as to operate with pellet. The
construction of the fireplace is made of steel, carried out by
plate welding. It consists of an inner ardent and outer
protective mantle, a circuit of the torch and pellet storage.
The ardent mantle is made of cooper plates 4 /W4/HII / DIN
17155.
The fireplace is equipped with a ventilator for equal
distribution of warm air, with the fluidity of ca 60m3/h. In this
way the warmth is equally distributed in the room where the
fireplace is installed.
The motion of flue gases from the torch rises up in the space
chamber where they cool down exchanging the temperature
with the mantle, and then pressed by another wave of flue
gas move to another space: exchange chamber. The mantle of
the chamber is a barrier around which the flue gases move,
exchanging their temperature, which is at the other side
taken by the ventilator and spread around the room. This
enables the warmth to be most efficiently used before it is
vacuumed into the funnel.
The furnace is constructed as a compact module. An electric
heater is used as an igniter that turns on and off
automatically. The heater is placed close to the electric
turbine. Controlled air supply is carried out by the electric
turbine by regulating the number of rotations of the turbine.
The supply of electrical energy is in accordance with all safety
regulations. The device is supplied with electrical energy per
plug device, that is in the case of fireplace supplied over a
inseparable cable (directly connected to voltage) per breaker.

USER MANUAL
www.kovan.ba

The conductor wire is ensured with a protective cable,
sections 3x1.5mm2.
All components of the fireplace that are exposed to high
temperatures are protected with fire proofed colors that
resist temperatures up to 700 degrees of Celsius. All other
parts are protected with an anticorrosive color in two
mantles. The outer mantle is protected with plastificaition.
There is no emission of gases into the room the fireplace is
placed in.
5.5. Applied regulations
During designing and construction of the fireplace, following
directives and regulations are applied:
Construction of the fireplace is harmonized in
compliance with European directives 98/37/EC,
97/23/EC and European standards EN 292-1:1991, EN

burner. Before letting the fireplace in operation, check the
patency of the chimney, flue pipe, as well as any devices for
protection from the wind.
6.4. Preparing for installation
The fireplace is supplied wrapped in protective foil. Beneath
the sheet, on top of the fireplace, you can find the
corresponding instructions and the guarantee card.
Place the fireplace on the planned installation location.
Connect the fireplace to the chimney so that there’s allowed
a slight drop to the fireplace or a horizontal position.
Connect the fireplace to electrical supply.
6.5. Electrical connection
DANGER OF ELECTRIC STRIKE
Before work on electrical parts, the
boiler must always be turned off from
the electrc power supply by physical
separation of the socket device from the
source of electric power

USER MANUAL
www.kovan.ba
18
All regulatory, controlling and safety appliances of boiler have
been wired and tested in the factory.
On an accessible place of the boiler ensure a connecting place
with a 1-phase outlet.
The place of the outlet should be properly selected so that
the socket device is always easily accessible.
Danger: In case of damage to the power
cable it is necessary to replace it with a
correct cable. Cable replacement should
be delegated to a competent person or
to the producers service.

USER MANUAL

Electric circuits of the fireplace are secured by an electric
safety fuse with a melting string of 2A. In case of fuse failure,
a professional qualified person needs to check the causes and
then carries out the fuse replacement with genuine fuse for
the same nominal electricity. Improvisation and „ patching “of
the fuse is strictly forbidden.
Note:
Electrical connection must
match the current regulations
for electrical installations in
households
You must have a protective
conductor
In the case of a direct power
cable connect, it is necessary to
install a switching device that
provides a reliable turning off of
the fireplace. The distance
between the contacts of the
device should allow the
exclusion of the overvoltage
category III conditions, in
accordance with the norms

Electric switch on/switch off the boiler
Switching on: Switch on the fireplace by plugging the
electrical cable into an accessible 1-phase outlet on the wall.
The illuminated display shows that the fireplace is under
voltage. Wait for a few seconds that the system needs to set
up. Afterwards, by the function keys you pass through the
access menu and perform any necessary adjustments.
Switching off: By pressing the button for switching off, the
fireplace goes in the switcing off process. That is the
procedure which, depending on the fireplaces working mode
lasts for a few minutes. After the switcing off process, when
displaying OFF on the display, the fireplace can also be
physicall separated from the electrical power source.
6.6. Putting into operation
Check if the type of pellet described in this manual matches
the type of pellet in your storage. The storage can be filled to
the top with pellet. Refill the storage with pellet when
needed.
Ignition and heating
The fireplace needs to be cleaned of ash and slug.
If an additional temperature regulator has been installed set
the wanted room temperature. All customers who have an
additional temperature regulator should activate it in the
fireplaces menu.
