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 stan-
dards and the technical regulations referred to in the manual. Its installation must be done by
a professional 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 pipe must be tight and its walls smooth, before connecting, it should
be cleaned o soot and any contamination. 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. Flue inspection should be carried out by a specialist
and any modications can be made by an authorized company so that they fullled the requirements
of PN-89/b-10425.

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 ope-
ration, 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 hardening of the paint) in the replace insert.
Before the rst ignition, remove all stickers or pieces of equipment that can be found in the combu-
stion chamber. During the rst ring in the insert, maintain the minimum temperature and slightly
open the door (approx. 1-2 cm), for the sealing material to be merged 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 emission of odour, always ventilate the room in
which the insert is installed.
Attention: 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 cham-
ber, the optimal amount of fuel is one that lls the combustion 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 that can be used is wood: oak,
hornbeam, ash, beech, 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, the use of coniferous wood is not advised. Green wood or poorly
dried fuel is not good because it has limited energy properties. Using such can result in greater
emissions of creosote in the ue pipes. Fuel for the inserts cannot include: minerals (e.g. coal), tropical
wood, (e.g. mahogany), chemical products or liquids, such as oil, alcohol, benzene, naphthalene,
laminated boards, impregnated or compressed pieces of wood with glue, garbage. If other fuels are
allowed, such information will be placed on the nameplate.
Housing of the replace insert: should allow access of air required for ventilation and air circulation
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 Infrastructure 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 feeding fuel and lockable
doors. They are designed for trimming or locating into a niche. Hardwood to be burnt includes:
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.

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.
DET AILS FOR FRANEK 10 - 10 kW
Eective area of grilles, inlet / outlet: The recommended eective area of inlet and outlet grilles for
cast iron air inserts up to 10 kW is:
air inlet (lower venting grilles) > 500 cm (eective area of the grille or the sum of grilles).
air outlet (upper venting grilles) > 700 cm (eective area of the grille or the sum of grilles).
DET AILS FOR FRANEK 12 - 12 kW
Eective area of grilles, inlet / outlet: The recommended eective area of inlet and outlet grilles for
cast iron air inserts up to 12 kW is:
air inlet (lower venting grilles) > 700 cm (eective area of the grille or the sum of grilles).
air outlet (upper venting grilles) > 900 cm (eective area of the grille or the sum of grilles).
DET AILS FOR FRANEK 14 - 14kW
Eective area of grilles, inlet / outlet: The recommended eective area of inlet and outlet grilles for
cast iron air inserts up to 14 kW is:
air inlet (lower venting grilles) > 800 cm (eective area of the grille or the sum of grilles).
air outlet (upper venting grilles) > 1000 cm (eective area of the grille or the sum of 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. alternately
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.

4. Mounting and installation of a replace insert
Installing a replace insert should be performed by a person with licenses for performing this type
of assembly work. It is a condition of safe use of the replace insert. The installer should conrm
the correct execution of the assembly by signing the stamped warranty card. Failing to full this
requirement makes the buyer lose the right under the warranty claims against the manufacturer of
the replace insert.
4.1. Preparation for installation;
Every replace insert is delivered ready for installation and trimming. After unpacking, check the
completeness of the equipment according to this manual.
Additionally, you should check the operation of:
• mechanisms for controlling the ow of air into the combustion chamber;
• the proper operation of the front door closing mechanism (hinges, handle).
4.2. Installation of a replace insert;
Installing a replace insert should be carried out in accordance with the relevant construction law,
re regulations and general regulations, in particular:
• Before choosing the location of the replace insert, examine all issues related to its placement in
terms of construction and re protection provisions;
• Check the mechanical strength of the substrate on which the replace insert is to be located, taking
into account the total weight of the insert and its housing;
• The replace insert must be installed on a non-combustible substrate with proper load- bearing
features and the oor at the door of the replace must be protected by a non- combustible material
belt with a width of 30 cm;
• Durability of the housing of the ue and smoke ducts must have a re resistance of at least 60 min.;
• • Installation of the replace insert can be made after a positive result of an expertise of the smoke
duct;
• The smoke ducts must meet the basic criteria, namely:
- it must be made of materials that weakly conduct heat;
- n the case of the insert with a diameter of the ue of 200 mm, the minimum cross-section must be
4 dm2;
- the ue duct can not have more than two inclinations of 45° to the duct height of 5 meters and 20°
at the duct height of over 5 m;
• The size of the ue draught must be:
- the minimal draught - 6 ± 1Pa;
- the mean recommended draught - 12 ± 2Pa;
- the maximum draught - 15 ± 2Pa;
• The mounting structure and the trim of the replace insert should be made of nonc-ombustible
materials and insulating materials, such as replace wool with aluminium coating, heat-resistant
insulating panels.
• The principles of good circulation and air balance in the room where the replace is to be installed
should be followed:
- distance of the insulation from the insert walls - 12-15 cm,
- - when using the air distribution system to other rooms, in order to obtain free circulation of air,
ensure that it could return to the room where the replace is installed after it is cooled down. Failing
to stick to this rule may disturb the cycle of the insert and prevent distribution of the heated air.
The room where the replace is installed must have a volume of not less than 30 m3and have a sup-
ply of the right amount of air into the stove of the replace. It is assumed that burning 1 kg of wood
in the replace with a closed combustion chamber requires approximately 8m3of air.

13
Distribution of hot air from the replace.
There are two ways to distribute the hot air in the room: gravitation and forced.
Gravitation hot air distribution system
When we heat an area of not more than the room where the replace is and adjacent rooms, choose
the gravity system. In this case, hot air will move upwardly into the chamber by way of the heating
pipes, the so- called thermal buoyancy. If you implement this system, remember to properly insulate
and keep the distribution pipes reasonably short (up to 3 meters). At the same time, hot air can not
be distributed to too many rooms. If the distance is more than 3 meters from the ue, hot air is not
able to overcome resistance and it does not reach the outlets or its speed is too low, with the result
that gravity ow is not sucient.
The advantage of this system are relatively small nancial costs to be incurred for installation. Disa-
dvantage - high temperature, which, in the absence of proper ltration, can cause serious adverse
health phenomenon, scorching dust (pyrolysis).
Forced hot air distribution system
The system requires the installation of a supply device - a turbine that sucks hot air heated by the
replace insert and pumps it to all branches of the system. Therefore, in this case, a ue pipe that
connects the insert with the air-supply device is used with the maximum possible cross-section and
the minimum length.
The DGP installation requires:
• ducts, pipes, passages, reducers, distribution boxes, lters, all made of galvanized steel;• kratki

• replace grilles or diusers as the end of distribution ducts;
• insulated exible ducts characterized by the minimal resistance up to 250 ° C (fully nonammable);
• supply device - a turbine.

5. Commissioning and operation of a replace insert
5.1. General comments;
Fireplace inserts are designed for burning wood with a moisture content of 20% and lignite briqu-
ettes. The use of coal, coke, coal derivatives, plastics, garbage, rags and other ammable substances
is prohibited. Conditionally, it is permitted to burn certied wood briquettes made from sawdust or
pellets. Practical evaluation of the humidity of wood fuel used is as follows. Wood which is to have
moisture content in the range of 18-20% must be seasoned for a period of 18-24 months or be sub-
ject to drying. With the reduction of moisture in the wood, the caloric value increases, which means
cost savings - up to 40% of the total mass of wood needed for one heating season. Using wood with
too high moisture content, excessive consumption of energy needed to evaporate the moisture may
be needed and condensate may be created in the ue or the combustion chamber, resulting in nega-
tive impact on space heating. Another phenomenon observed with the use of wood with too great
moisture content is the phenomenon of the formation of creosote - sludge (steam from wet wood
and soot) being destructive to chimneys, which can cause inammation and re of the chimney.
5.2. Starting the replace;
Before trimming the replace, conduct a few test ignitions, during which you should check the opera-
tion of the moving parts of the insert. Newly installed replaces must be operated with the power of
approx. 40% of the nominal power in the rst two weeks of use, with the temperature gradually incre-
ased. This way of the use of the insert enables gradual removal of internal stress, thereby preventing
thermal shocks. It has a very large impact on subsequent insert parts durability and the durability of
the ceramic Acumotte linings. During the rst few startups, the insert can emit the scent of enamel,
silicone sealant and other materials used to perform the installation. This is a normal phenomenon
which disappears after a few cycles.
Note: Do not use the replace insert when it is not trimmed, except for the test rings.
5.3 Operating the replace;
Note: During all activities related to maintenance and operation of the insert, remember that
the steel parts of the insert may have high temperatures and therefore protective gloves
should be used.
Firing
In order to start a re in the replace insert, open the insert door using the handle, place the kindling
(dry paper, sawdust or other approved replace kindling types are recommended), lay shredded
wood on it and then wood logs. We do not recommend the use of synthetic relighters because they
contain chemicals which can give o specic odours. Then, set the air intake to the replace in the
fully open position (the regulator is below the insert door), ignite the kindling, wait until the kindling
is burning. close the front door of the replace.
Note: It is forbidden to use other materials than those provided in the instructions. Do not use
ammable chemical products to ignite, such as oil, gasoline, solvents and others.

15
Combustion air is supplied only from the outside.
The standard insert has a built-in air intake from the
outside - intake connector diameter of  125 mm. The
separation of air to the combustion chamber takes place
in the space (air chamber) below the lower insert plate.
The heater has a triple system of ventilation of the
combustion chamber: primary air (under the grate) - con-
troller no. 1, secondary controller (rear wall) - controller
2 and the air curtain (on the glass) - controller 3. The
primary air is cold air directed under the grate (ash pan)
from three sides of the grate. This contributes to impro-
ving the conditions of combustion. Combustion takes
place simultaneously on the whole surface. Regulation of
primary air supplied under the grate (the ash pan) is done
through the controller below the insert door, rst on the
left (controller no. 1).
The secondary air is already heated and transferred
through holes in the rear wall of the furnace to the
appropriate height - the afterburner system of ue gases
is responsible for the combustion of gases and reducing
the emission of harmful substances into the environ-
ment. Increases the eciency of the insert.
Due to the use of this solution, inserts achieve very good CO performance (low CO emission).
Regulating the amount of secondary air is carried out through a second controller, located below the
cover of the insert, rst on the right (controller no. 2)
The third, independently controlled circulation, is air curtain - the clean glass system without air
intake from the room.
This is a special aeration windows enabling keeping it clean. Air is drawn from the space (air cham-
ber) below the bottom plate of the insert, and it is supplied through special ducts on the sides of the
replace (where it is heated) into the chamber on the top cover of the replace and evenly distribu-
ted on the glass, so that it remained clean. Regulation of the amount of air inlet onto the curtain is
carried out through the controller located above the combustion chamber, visible after opening the
door of the furnace (controller no. 3)
Operation principle.

Air circulation / adjustment
Triple aeration enables combustion of gases and particles in fuel gases. It improves the insert ecien-
cy, saves wood, making combustion in the insert clean and economical.
Adjusting aeration of the combustion chamber is independent of all three systems.
Due to that the user has a better control over combustion.
Combustion, loading
After lighting the re and partial burning of the rst batch used to ignite and produce a layer of
ignition grate, add wood to the combustion chamber of the insert, arranging fuel to evenly ll the
chamber according to the expected time of ring, as specied by the user, basing on individual
experiences, but not more than 1 / 3 of the total capacity of the combustion chamber.
During burning, the replace insert front door is to be closed. The intensity of the combustion
process in the replace insert must be adjusted with a regulator on the air inlet.
Combustion chamber cleaning
Control the level of lling the combustion chamber with ash, as in the case of excessive levels, the
ow of combustion air is limited. Removing ash from the replace is to be done after the insert is
extinguished and cools down, while respecting compliance with re regulations. In order to remove
ash from the combustion chamber, close the air intake using the regulator, open the insert door slow-
ly and remove the ash by using suitable accessories, a replace vacuum cleaner or an ash separator.
The manufacturer recommends emptying the ash drawer after each use.

17
Operational safety
During operation and use of the replace insert, stick to the rules that assure the basic security
conditions:
• Refer to the owner’s manual of the replace insert to strictly observe its provisions;
• The insert must be installed and ignited by an installer having appropriate qualications, experience
in operating replace inserts;
• Do not leave things sensitive to temperature near the insert glass, do not extinguish the re in
the stove with water, do not operate the insert with the glass broken, ammable items can not be
present in the vicinity of the insert;
• Do not allow children unaccompanied by an adult to stay in the vicinity of the replace;
• Apply the principle of slow opening the front door, additionally, if the draught regulator is used on
the ue of the insert, always remember to open it.
• Any repairs must be done by an installer with relevant licenses and the insert manufacturer’s spare
parts should be used;
• Any changes to the structure, the installation, the use rules without the written permission of the
manufacturer are unacceptable.
5.4 Maintenance of the replace insert;
Maintenance activities of the replace insert and smoke ducts consist of ensuring compliance with
the following guidelines.
Periodic or ordered maintenance of the insert include:
• ash removal, cleaning the glass, cleaning the combustion chamber, cleaning the ueduct;
- The manufacturer recommends emptying the ash drawer after each use.
• periodic cleaning the combustion chamber of the insert (the frequency of this operation depends
on the species of wood used and humidity);
• cleaning the combustion chamber requires the use of a poker, a scraper, a brush or ash vacuum
cleaners or separators
• the glass should be cleaned using a formulation intended for the purpose.
Do not use abrasive cleaning preparations, as this will scratch the glass;
• cleaning the ue ducts should be carried out by a chimney sweeper and documented in the insert
documentation (duct cleaning is to be performed minimum twice a year).
The replace does not allow for self-assembly / disassembly of any of the steel parts of the insert.
Independent replacing may be considered in the case of consumable parts, that is:
- the sealing
- grate
and whenever necessary:
- pane
- fence
Note: All and any maintenance can be performed only when the replace insert is fully cooled
down.
6. Anomalies in the operation of the replace insert
During operation of the replace, some anomalies can happen, suggesting irregularities in the ope-
ration. This may be caused by improper installation of the replace without sticking to the existing
legislation or the provisions of this manual or due to external causes, e.g. the environment. The most
common causes of the insert malfunctions along with their solutions are listed below.

18
a) Smoke return with the replace door open:
- too sudden opening of the door (open the door slowly);
- - if an air vent has been installed as a draught regulator - open the air vent every time you open the
insert door;
- insucient air supply to the room where the replace is installed (provide adequate ventilation
in the room or bring air into the combustion chamber in accordance with the guidelines in the
manual);
- atmospheric conditions;
- too little chimney draught (inspect the chimney ue).
b) Insucient heating or extinguished stove:
- a small amount of fuel in the stove (ll the stove according to the instructions);
- too high moisture content used for burning (use wood with a moisture content of 20%);
- too little chimney draught (inspect the chimney ue).
c) Insucient heating, despite a good combustion in the combustion chamber:
- low-calorie„soft” wood (use wood according to the recommendations in the manual);
- too high moisture content used for burning (use wood with a moisture content of 20%);
- too chipped wood.
d) Excessive dirt on the glass of the insert:
- low intensity of burning (do not use frequent ring at a very low ame, use only dry wood as fuel);
- the use of coniferous resinous wood as fuel (dry hardwood timber described in the manual of the
insert should be used as fuel). e) The proper functioning of the insert can be disrupted by weather
conditions (humidity, fog, wind, atmospheric pressure), and sometimes by nearby localized tall
buildings. In the case of repeated problems, please contact an expert chimney company to conrm
the cause of this situation and to nd the best solution to the problem.
NOTE: In the case of slow burning in low temperatures, excess of organic products of combu-
stion is generated (soot and water vapour), forming creosote that can ignite in the smoke duct.
In such a case, rapid combustion takes place (large ame and high temperature) - referred to as
the chimney re. In the case of such a phenomenon:
• close the air intake from the outside;
• check the correctness of closing the front insert door;
• notify the nearest re brigade unit.

The warranty scope shall not cover the following:
- pane - heat-resistant ceramics (resistant to temperatures up to 800 ° C);
- all defects arising due to non-compliance with the provisions of the manual and, in particular,
those referring the fuel and kindling used;
- any defects caused during transportation from the distributor to the buyer;
- any defects caused during installation, construction and commissioning of the replace insert;
- damage resulting from thermal overload of the liner (related to inconsistency with the provisions
of the manual of the insert).
The guarantee is extended for the period from the date of ling the complaint to the date of the
notication of the buyer of the repair being done. This time will be conrmed in the warranty card.
Any damages caused by improper handling, storage, poor maintenance, incompatible with the
conditions laid down in the operation and maintenance manual and due to other reasons not attri-
butable to the manufacturer, will void the guarantee, if the damage contributed to the qualitative
change of the insert.
Note: It is forbidden to use coal as fuel in any of our inserts. Burning coal in each case involves a
loss of the guarantee. Any customer reporting a failure under warranty is always required to sign a
declaration that they did not use coal and other fuels prohibited in our insert. If there is suspicion of
the use of the above-mentioned fuels, the replace has to be assessed to investigate the presence of
prohibited substances. If the analysis shows the use of them by the customer, any rights under the
guarantee are lost and the customer is obliged to cover all costs associated with the claim (including
the costs of the expertise). This warranty card is the basis for the purchaser to perform warranty
repairs free of charge.
Any guarantee card without a date, stamps, signatures, as well as including any amendments made
by unauthorized persons expires.
Duplicates of warranty cards are not issued!!!
