Thank you for the condence shown to us by purchasing the replace insert manufactured by
kratki.pl. Before tting and using the insert, please read these instructions.
General information
NOTE! To avoid the risk of re, the device must be installed in accordance with the current standards
and the technical regulations referred to in the manual. Its installation must be done by a profession-
al or a qualied person. This device complies with the EN 13229 and is CE certied.
Always obey the laws of the place where the device is installed. First, make sure that the ue is
suitable.
The device must be installed in accordance with the current standards of the construction law.
The insert must be set at a safe distance from any ammable products. It may be necessary to protect
the walls and the materials around. The unit must stand on a solid, non-combustible base. The ue
must be tight and its walls smooth, before connecting, it should be cleaned of soot and contamina-
tion. The connection between the ue and the insert must be tight and made of non-combustible
materials protected against oxidation (an enamelled or a steel pipe).
If the ue produces weak draught, consider laying new pipes. It is also important for the ue not to
produce excessive draught, you must then install a draught stabilizer in the ue. Alternatively, there
are also special ue endings regulating draught. Control of the ue draught should be carried out by
a chimney specialist, any modications can be made by an authorized company, in order to have the
requirements of PN-89/b-10425 fullled.
The rst ignition WARNING!
At the rst ignitions, the device should function at slow run, to enable the parts’normal dilation.
Door handles and other handles are warm during operation of the insert. During operation, you
should use protective gloves. Acrid smoke and smell coming from the insert during the rst ignition
are not a cause for concern - this phenomenon is caused by paint burning (polymerization or harden-
ing of the paint) in the replace insert.
Before the rst ignition, remove all stickers or pieces of equipment that can be found in the combus-
tion chamber. During the rst ring in the insert, maintain the minimum temperature and slightly
open the door (approx. 12 cm) for the sealing material to be connected with the varnish. All materials
must slowly adapt to high temperatures.
During the rst few usages, each insert emits an unpleasant smell, caused by paint burning. This
smell will disappear after a short time. During the smell emission, always ventilate the room in which
the insert is.
Important: before lighting a large re, light a small one be two or three times. This will enable the
insert structure to be rmed and the paint to be hardened.

Do not put wood to the full of the chamber, the optimal amount of fuel is one that lls the com-
bustion chamber in about 1/3 of its volume. Before adding wood, wait until the ames are lower,
do not add wood while burning as well as too much grate.
Fuel: due to the design of our equipment, the recommended fuel can be: oak, hornbeam, ash,
beech wood, etc. It is also acceptable to use brown coal briquettes and charcoal. The best fuel
is dried wood (at least 18 -24 months in a well-ventilated and dry place); cut and crushed logs.
Because of the very rapid ignition
it is not advise to use coniferous wood. Not dried wood or not well
dried wood is not a good fuel, because it has limited energy properties. Using such can result
in greater emissions of creosote in the ue pipes. It is not allowed to use: minerals (e.g.: coal),
tropical wood (e.g.: mahogany), chemical products or liquids, such as oil, alcohol, benzene, naph-
thalene, laminated boards, impregnated or compressed pieces of wood with glue, garbage. If other
fuels are allowed, such information will be placed on the nameplate.
The housing of the replace insert: should allow access of air required for ventilation and air circu-
lation in the housing by applying grilles selected according to the insert power (in the lower part
of the envelope - under the insert) and an outlet grille (at the top of the envelope - over the insert).

1. General comments
a) Before installing a replace insert have an expertise executed and commissioning of the ue in
terms of its technical characteristics and the technical condition - leaks, blockages.
b) Installation and commissioning of the replace insert should be done by an installation company
having adequate licenses for this purpose and experience.
c) The replace insert should be located as close to the ue as possible. The room in which it will be
installed must have an ecient ventilation system and the necessary amount of air required for the
proper functioning of the insert.
d) While moving, do not grab the handle of the insert, as it may get damaged.
e) Before using the insert, remove stickers from the glass.
f) Technical parameters of the insert apply to the fuel specied in this manual.
g) It is essential to comply with ue service intervals (at least 2 times a year).
h) pursuant to the current law, a replace can not be the sole source of heat but it can only supple-
ment the existing heating system. The reason for this type of regulation is the need to ensure the
heating of the building in the event of prolonged absence of people. Installation of a replace
insert must be carried out in accordance with the provisions of standards in force in this eld, the
requirements of construction law and the applicable re safety standards. Detailed rules for the
structural safety, re safety and safety in use are contained in the Construction Act of 7 July 1994
(Journal of Laws No. 156, item 1118 of 2006, as amended), Regulation of the Minister of Infrastruc-
ture of 12 April 2002 on technical conditions which should be met by buildings and their location
(Journal of Laws No. 75, item 690 of 2002, Journal of Laws No. 109, item 1156 of 2004), the PN-EN
13229:2002 standard “Fireplace inserts with open res using solid fuel. Requirements and Tests.”
2. Intended use
The replace inserts manufactured by Kratki.pl use solid fuels with manual loading of fuel and
lockable doors. They are designed for trimming or locating into a niche. They are designed to
burn hardwood i.e. hornbeam, oak, beech, acacia, elm, maple, birch, with humidity <20% (lignite
briquettes and wood briquettes are also acceptable). They serve as an additional source of heat in
the rooms in which they are installed. Installation of an insert should be structured in a way that will
allow assembly and disassembly of the replace, without having to destroy or damage it. It should
also ensure access of air needed to circulate around the insert by using replace grilles.
Selection of grilles.
Intake and outlet grilles: In the lower part of the trim of a replace insert, provided an air hole (s) to
supply air required for heating through the trim - air intake (lower
an air hole (s) to supply air required for heating through the trim - air intake (lower
grilles). To ensure proper exhaust of hot air from the hood, provide exhaust holes in it with ventilation
grilles - air outlet (upper ventilation grilles). The holes are nished using grilles of cross-sections
depending on the insert power, from 40 to 60 cm2 per 1 kW of the replace insert.
Note: Because of the high temperatures in the housing of the insert, the grilles in the hood and the
air distribution crowning the system in the house have to be metal. Only grilles without blinds are
allowed in the replace hood.
Eective area of the grilles: The recommended eective area of the inlet / outlet grilles for surface
inserts (steel or cast iron) to 10 kW, it is the air intake (lower ventilation grilles) / the air outlet (upper
ventilation grilles) cm2 ≥ 500 cm2 (eective area of the grille or all of the grilles) for inserts to 15 kW,
it is the air intake (lower ventilation grilles) / the air outlet (upper ventilation grilles) cm2 ≥ 700 cm2
(eective area of the grille or all of the grates), and for inserts over 15 kW, it is the air intake (lower
ventilation grilles) / the outlet air (upper ventilation grilles) cm2 ≥ 800 - 1200 cm 2 or more (eective
area of the grille or all of the grilles).
Decompression grilles: Very high temperatures are recorded inside the hood, therefore, inside the
hood, approx. 40 cm from the ceiling of the room, a decompression shelf should be tted i.e. a ceiling
over the insert. It prevents heating of the ceiling of the room, heat losses and forces the installation

of proper exhaust grilles under it to emit exhaust heat from the chamber above the replace.
Grilles (decompression ones) are mounted on both sides of the housing on opposite sides, e.g. alter-
nately higher and lower than the decompression shelf. They enable intensive air ow - circulation,
which cools the surface of the ceiling. The size of the grilles - their eective area is not important.

Solutions used in the Nadia series of replace inserts enable changing the standard left-hand door
opening to the right-hand one. First, protect the safety element of the insert door against accidental
falling down from hinges (1). Following opening the door to an angle of 90°, lift it to release the lower
hinge (2) (3). Next, remove the glass and rotate it by 180° (4) (5) (6). The glass is mounted with two
slats which must be removed by unscrewing ten M5 hexagon socket screws. After reversing and
reinstalling the glass, start to reverse the limiter (7) (8). The limiter is a symmetric part dismantled by
unscrewing two M5 hexagon socket screws. The element is mounted in the lower part of the door.
Fireplace door modied in this way should be rotated by 180 ° and installed in the insert as illustrated
in (9) (10) (11). After installing the door, secure them with the safety element (12).
