Congratulations! You have just bought the fireplace insert HAAS + SOHN, a top-quality product.

Thank you very much for your interest and purchase. Kindly read the Manual to find out about the
function, correct use and handling. We recommend you to read the instructions carefully in order to
avoid any risk related to likely damage. Proper operation and maintenance affects the service life of
the product as well. In addition, proper operation and fuel supply is connected with fuel savings and
environment protection. The technical specifications are shown in the Technical Card (included in
the booklet).

The manufacturer provides guarantee providing you adhere to the directions and recommendations
in the instructions for operation and maintenance. Keep the Operating Instructions and the Technical
Card safe to be able to refresh your knowledge at the beginning of the new heating season.

The General Instructions for Operation, Installation and Maintenance are valid for any type of
the fireplace inserts supplied by HAAS + SOHN. The Technical Card provides detailed
technical parameters for the particular type.

1. TECHNICAL SPECIFICATIONS
Fireplace inserts are designed for heating in habitable rooms, recreation buildings, work stations and
other places to provide thermal comfort. A fireplace insert is used as a closed fireplace while the
visual effect - the perception connected with flame - is similar to the sensation of live fire. In
comparison with conventional open fireplace, the insert is characteristic with higher thermic
efficiency. Another advantage of fireplace insert is the high safety level – no danger from flying
brands while flue gases spreading throughout the heated area is limited.

1.1. General requirements on fireplace insert installations

A fireplace insert is either integrated in the fireplace composition or –without casing – may be
installed in another way at the particular position. It is located in the particular interior on request and
specification by the customer or on architect’s design, viewing the concrete arrangements within the
room(s) to be heated. The installation and the connection to the vent must be approved by an
authorised chimney-sweep company ahead of time. It is recommended to give an order for the
installation and lining at a specialist stove-building company. For a basic layout of a single-shell
fireplace insert see Supplement 1.

Caution! Fireplace inserts may be installed only in rooms and positions risk-free in terms of
the position, building conditions and intended use. The walls and the ceiling at the
installation area must be free of electric lines. For the rooms with a fireplace insert installed,
sufficient air supply for the firing process must be provided. The base area – the place of the
installation – must be proper construction and size to allow standard operation of the hearth.

1.2. Heating concept

Fireplace inserts are designed for burning wood, eco-fuel cakes and coal cakes (specific types only)
in a burning-through way, characteristic with very good firing conditions.
The air within the room is heated thus the thermal comfort is provided by heat convection, in part by
heat radiation as well. This way, you can heat up even very cold, long-time unheated rooms very
quickly. The heat convection means that the cooler air sucked- in at the area of the bottom part of
the insert is heated inside the convective area (comprising of double shell of the heating device or its
casing, where the heating process takes place). From there, the heated air is led back in the room
via the holes in the upper part of the casing or the insert. The radiation heat is generated by means
of surface areas of the stove (metal, ceramics, glass). Due to the construction, the biggest radiation
heat source is the glass door.

1.3. Construction design

Fireplace inserts are welded of steel profiles, thickness 2-5 mm. In the middle of the insert, there is a
firing chamber that may be closed with the door (equipped with a self-acting element). The door is
provided with special large-area glass sheet, thermal resistance up to 800 °C.

3 4

The inner space of the firing chamber is usually lined with fireclay brick shapes. The brick shapes
are not jointed with any filler (the reason is a protection of the bricks against damage by thermic
dilatation). The upper part of the firing chamber is equipped with partitions designed for directing
flue gases into a smoke outlet. The partitions may be fixed or movable. Such movable partition may
serve as a supporting holder for fireclay brick shapes. At the bottom part of the firing chamber, a
simple, fixed cast grate is installed. Before the grate, a barrier is usually provided, to prevent from
burning pieces falling out or onto the door (front glass). Under the grate, there is a space designed
for ashpan. The remaining space at the bottom part of the stove may be used for spare fuel. With
certain models, the smoke flue neck may be adjusted for upper or rear outlet of the smoke: you just
release the clamps and rotate the neck of the smoke flue set in the required direction.
The fireplace insert may be a single- or twin-shell model. The twin-shell type is designed to provide
direct support to the convective stream flowing through the outer construction of the insert body. The
convection holes at the bottom part of the insert allow the air inlet in-between the insert and the
casing. The steel construction of the fireplace insert is protected with special refractory paint.

Caution! Fireplace inserts are not designed for continuous heating but for periodical –
interrupted (i.e. temporary) operation.

2. FIRING PROCESS

2.1. Fuel quantity and firing process adjustments

Burning wood, wood cakes (or coal cakes – optional) in fireplace inserts is based on burning through
the fuel, which means that such firing takes place throughout the whole go of the fuel at a time. In
order to provide optimal conditions for easy kindling and burning up, you need enough air being led
under the fuel in fire, through the grate: this is the so-called primary air, and it must be always
adjustable. By increasing temperature of the fuel burning through, certain gaseous components of
the fuel evolve that – unless additional air is supplied – would be of no avail in terms of heat energy:
therefore, additional air must be provided at the flame level where the firing process connected with
those gaseous components may continue. Now, at this stage, the primary air is – in fact – not
necessary, while secondary air supply is required, or tertiary air may be added as well,
respectively. The secondary air supply, usually adjustable, improves the firing process and
contributes to the door glass self- cleaning. The tertiary air supply is designed for general
improvement of the burning process and is usually fixed (one cannot regulate it anyhow). If the
proportion of the air volumes led into the particular sections of the firing chamber is correct, the
burning efficiency is increased while emission of pollutants in the environment is reduced. The
layout of the air supply regulative elements is shown in the Technical Card (a part of the
documentation supplied with the fireplace insert).
The heating capacity of the heating device depends on the fuel quantity burnt per defined time, fuel
quality and firing process efficiency. The data shown in Chart 2 (heating values) may help you to
make a picture of attainable capacity: let’s assume that you burn 1 kg of wood per hour, wood
moisture is 20%. Further, with higher wood moisture its heating capacity goes down.
In the testing room conditions, adjustability of the heating device was tested, within 30 – 100% of
nominal performance. For the regulation, the chimney effect and the fuel quantity were applied. In
practice, the heating capacity may be regulated by means of air supply regulating elements
(especially the primary air inlet). There is no simple and explicit way to determine the firing process
adjustment by means of regulators. There are many aspects to consider – fuel moisture, type of
fuel, chimney effect, exterior pressure conditions, etc. Therefore, the firing process (the flame
intensity and quality) should be re-adjusted for particular conditions.
You will be able to adjust the firing process to achieve best efficiency after a short time of operation.
A detailed chart showing how to adjust the air supply regulating elements is included in the Technical
Card. The figures in the chart are the testing results verified by the State Testing Laboratory. The

Our tips for wood burning

• Any time you set the fire, let the primary air regulator open long enough to allow the fuel
burning properly.

• Before you re-load, it is recommended to open the primary air regulator wide.

• While burning wood, make sure the wood is dry, maximum moisture 20%.

Our tips for coal cake burning (selected models only)

• To achieve optimisation of the firing process, load the cakes directly onto the grate holes: this
way, you support the burning in best possible way.

• Make sure you do not overload: for the heat capacity you may use, i.e. to maintain the heat, a
couple of cakes is enough: otherwise the device would suffer from excessive heat. Coal cake

fuel efficiency may reach 6 kWh/1 kg, i.e. by some 40% more than wood!

2.2. Fuel

For fireplaces, you may burn logs, wood cakes and coal cakes (some models only). The moisture of
the wood to be burnt should be lower than 20%, optimally 10%. The rule of thumb is: the less water
in the fuel, the higher heating capacity you achieve. For the recommended wood moisture, you may
reach it safely if you store the wood in a well ventilated shelter for at least two years. The water
content in coal cakes should be specified by the manufacturer. The cakes should be stored in a dry
room otherwise they disintegrate. It is recommended to store the wood intended for burning in pieces
approx. 3-6 cm (diameter), 20–30 cm (length). It is forbidden to load and burn coal or charred
coal. In the fireplace, never burn flammable liquids or waste. It is forbidden to burn papering,
chipboards, plastic materials, penetrated wood, wood shavings or saw dust. Burning such materials
not only is detrimental to the environment but shortens the service life of the heating device as well:
you might seriously damage the device or the chimney as well.

Note: The bark, a part of wooden logs, is no issue at all.

3. SAFE OPERATION

3.1. General requirements

While installing and operating stove insert, it is obligatory to adhere to the fire prevention
regulations (related to this type of devices) in force in the country of installation.

The device is designed for standard environment. In case of any temporary change establishing any
temporary danger of fire or explosion (for example, while installing linoleum flooring, PVC, painting,
etc.) it is crucial to put the heating device out of operation IN TIME, BEFORE ANY POTENTIAL
DANGEROUS SITUATION MAY OCCUR. At the end of the work, do not start using the fireplace
again until the room conditions are brought back to normal (it is recommended to provide fresh air by
draught).

3.2. Safe distance between the fireplace insert and flammable material

If you have installed a fireplace insert within the room with flammable objects, flammability Class B,
C1 and C2, the safety distance from the front (or side glass surfaces) is 800 mm; for the other
directions, the safety distance is 400 mm. If the insert is installed within a room with flammable
objects, flammability class C3, the safety distances must be doubled. Kindly pay attention to the
information provided in Supplement 1 and 2. The most important installation dimensions are
shown in the product name plate.

3.3. Safe distance between the smoke flue and flammable material

The safety distance from the door frame lining and similar constructions made of flammable
materials, and from pipeline installations, incl. insulating elements is 200 mm (minimum). The
safety distance from the other parts of the constructions made of flammable materials is minimum
400 mm. This is applied to construction materials, flammable Class B, C1 and C2.(see Chart 3).
Kindly pay attention to the information provided in Supplement 2. More accurate classification is

available only if testing is performed for the particular product.

3.4. Directions for safe operation

For firing or kindling, never use any flammable liquid! It is forbidden to burn any plastic material,
wooden material combined with chemicals (chipboard, etc.) or domestic (unsorted) refuse containing
plastic, etc.

The insert must be operated by adults only! Never allow children in the room unattended. The
surface of the fireplace insert is overheated, especially the glassy components: any contact
will cause serious burnt. During the operation, occasional monitoring is required. For safe

operation and handling the regulation elements and the door closing devices, use the protective
glove (a part of the supply) .
Do not put any objects or tools on the insert while in operation or hot: flammable material may cause
fire.
The ashpan must be manipulated with utmost care. The ash may be very hot so there is danger of
serious burnt. Hot ash must not be in contact with flammable material – for example, while pouring it
into waste container.

The fireplace insert must be operated in compliance with the directions and
recommendations in the Operating Instructions. It is forbidden to modify the insert in any
way unless approved by the manufacturer.

4. INSTALLATION AND CONNECTION TO THE CHIMNEY
Caution! For installation, relevant local regulations must be strictly adhered, including the

regulations related to national and European standards for this type of device.

4.1. Connection to the chimney or chimney insert

Connection of the fireplace insert to the chimney vent is subjected to approval by specialist chimney
company (ČSN 73 4201:2008), or to approval according to relevant regulations in force in the
country where the installation is made. Kindly pay attention to the information provided in

Supplement 2.

To provide proper function and operation, proper chimney effect in the smoke flue neck is
required. For the minimum stack draught, see the Technical Card for the particular product.

Insufficient chimney effect results in malfunction of the insert, excessive dirt on the glass, and
excessive clogging in the smoke flue system. The general heat capacity of the device is reduced. If
you feed the fire while proper chimney draught is not provided, flue gases may spread throughout
the room. For this reason, it is strictly recommended to have regular check done by a specialist
chimney company and maintain the heating device regularly. If the chimney effect is too high (over
20 Pa) it is recommended to install a suitable blocking device (for example, flue tube with a block).
Excessive chimney draught may cause troublesome operation, for example, too intensive burning,
high fuel consumption , damage on the heating device, etc.

Caution! It is recommended to connect fireplace inserts with rear outlet to the chimney by
direct connection (without an elbow element). Any other method of the connection should be
approved by a specialist chimney company.

4.2 Connecting the stove insert to the venting unit
It is recommended to connect the stove (insert) to a separate chimney vent. A joint chimney
vent may be used for the connection only if the safety regulations valid in the country of
installation allow doing so. It is forbidden to connect the stove (stove insert) to the same vent
used for a gas appliance. The minimum working height of the vent is 5 m. Depending on local
conditions, it is possible to connect the stove in the vent with a working height under 5 m
providing that the flue way calculation demonstrates that such a height is satisfactory.
Caution! (Provisions CSN 73 42 01: 2008)
The smoke flue vent diameter must not exceed the diameter of the chimney vent; it must not
be narrowed towards the chimney, either. If the calculation demonstrates that the vent
diameter of the smoke flue and chimney can be smaller than the flue neck diameter of the
device, the diameter of the smoke flue will be reduced just after the flue neck of the device, by
means of a short transition or abrupt.

4.3. Directions for smoke flue installation and safety

Connect the smoke outlet neck with the chimney in the shortest possible way so that the length of
the smoke path is no longer than 1.5 m. The smoke pipes and the elbow piece must be tightly
connected, overlapping at least 60 mm. Pay special attention to the fact that the joints must agree
with the flue outflow. The joint between the smoke flue and the smoke outlet neck must be drilled
together and fixed with a rivet or pin; the same is applied for the smoke pipes and the elbow. The
hole (entrance point) in the chimney must be provided with a metal stress ring (proper diameter).
The smoke flue should ascent towards the smoke uptake at angle approx. 10°.

4.4. Installation of the fireplace insert within the room

Before any installation work is started, you need to verify the floor (ceiling) load capacity. The load
conditions for the particular type of the device must be met (depending on the particular weight),
including the weight of the casing. It is recommend to contact a statics specialist. The fireplace insert
must be installed on a heat insulating base that overlaps the stove ground plan dimensions on the
sides and in the rear by at least 400 mm; the overlap in the front (the direction of the feeding

opening) is 800 mm. If a metal base is used, the thickness must be at least 2 mm.
For safety distances from the outer surface of the insert body and the smoke flue, see
Chapters 3.2 and 3.3.
Caution! Make sure you provide space enough for easy approach to the heating device, smoke flue

and chimney for the purpose of cleaning.

7 8

4.5. Cleaning the heating device and chimney

It is necessary to provide approach to the piping (smoke path) for occasional cleaning by means of,
for example, a removable part of the casing at the area of the smoke flue. We recommend you to
advise of the requirement the company whose technicians will install the fireplace insert for you.
Further, approach in the chimney for occasional cleaning is required as well.
By regular cleaning of the smoke pipes and the firing space in the fireplace insert, you may optimise
the performance of the heating system and guarantee a trouble-free function and operation. By
regular chimney cleaning, you avoid inflammation of fouling solid particles caught on the chimney
walling.

4.6 Fire in the chimney
In case of fire in the chimney, put out the fire in the stove immediately: remove the burning
fuel remnants with a shovel (put them aside in a suitable non-flammable container) and call
the fire brigade immediately: Call the fire brigade or the integrated rescue system centre.

4.7.

External combustion air supply

For the firing process, enough fresh air supply is needed.. While firing wood, the device needs up to
15 m3 of fresh air per hour. In case of newly built houses, the insulating materials used in the house
result in low airiness coefficient, due to plastic windows, etc.). Another issue may be exhaust
devices or other heat installations in operation in the room or within the space where the fireplace is
installed. In such well-insulated houses, the quality of the firing process is lower, being accompanied
with tarring and smoke path clogging (and/or smoke penetration and spread in the room). Make sure
that the air supply in the room is sufficient, by open windows or door in the next, better ventilated
room. It is more convenient if you – along with the installation of the heating device – install a
ventilation hole to provide air supply, equipped with a regulating grate (should be protected against
clogging). It is recommended to verify whether the air supply is sufficient, by - for example – using

the procedure TPG 704 01 “Gas consumption devices and appliances with gas fuel installed in

buildings“.

4.8. External air supply system

Modern fireplace inserts are designed with an external combustion air supply. This way, enough air
is supplied for making the firing process perfect, especially in case of houses with low airiness
coefficient (well insulated from the external environment due to construction elements reducing
natural air circulation (plastic windows, doors etc.). Such external additional air supply should be
connected to the system chimney, whose part is a vent. This is offered by means of, for example, a
chimney system made by SCHIDEL. Another option is a connection with space where the air
circulation is sufficient – e.g. by means of a passage through the wall into the exterior. The best
solution for the particular house should be suggested by the specialist chimney company or the
company responsible for the installation of the fireplace insert.

5. OPERATING INSTRUCTIONS

5.1. Before first operation

If the fireplace insert is supplied without casing
Before the first putting into operation, you have to remove labels from the glass, accessories found in
the ashpan or inside the hearth, including transport clamps etc. Following the illustration in the
Technical Card, check that the movable partitions designed for directing the flue gases, fireclay brick
shapes or the barrier are located properly (they may have moved out of the position during the
transportation or installation work). If you find any wrong position, correct it; otherwise, the heating
device might not work properly.
When the fireplace insert has been positioned and connected to the chimney system, make (not very
big) fire, maintaining it for approx. one hour.

As soon as the device gets cold again, it is possible to install the outer lining.

If the complete fireplace set is supplied

Following the instructions for installation, place and connect the fireplace insert to the chimney
system (including the installation of protective sheets –if used – and insulation of the smoke piping).
After that, install the lining (follow the instructions and illustrations). Then, install the fireclay layer in
the hearth of the fireplace insert. For the very first fire, use smaller quantity of wood, maintaining the
fire for at least one hour.
The insert surface layer is provided with fire-resistant paint being softened during the first fire made
in the stove to become harder afterwards. During the soft phase, pay special attention to danger of
damage on the surface by touching it with fingers, tools, etc. For the very first use, the initial fire
should be very small, to “warm up” the device gradually: it is recommended to load smaller quantities
to establish lower temperature. All materials need the initial lower- temperature phase in order to “get
used to” the thermal stress. By such slow heating up, you avoid cracks in fireclay bricks, likely
damage on surface paint or material deformation in general. The odour generated during the paint

hardening process at the first putting into operation is just temporary – however, it is
recommended to ventilate the room intensively. If pets are present, move them to another room

for a while.
With the models equipped with the glass door comprising of three parts, check the segments for
gaps (which may be formed during the transport or the first use).
What to do if you find a gap between the glass segments: Partially release the holder nuts. Move
the glass segments (carefully!) closer to each other: the edges should touch slightly. Slowly and
carefully, tighten up the holder nuts.

5.2. Setting the fire

To set the fire easily, follow this procedure: Put 2 or 3 smaller wooden logs onto the bottom or on the
grate. Add paper or permitted fire lighters, then brushwood, small firewood and thicker logs (the last
layer). You should always load a bigger quantity (i.e. enough wood , which means up to approx. 2/3
of the height of the fireclay (vermiculite) lining. By loading such bigger quantity, you establish time
long enough in order to heat the chimney thus set the proper conditions for the chimney function.
Open the primary air regulator wide (maximum). Sometimes it is good to reduce the secondary air
supply at this moment – the fuel catches the fire better. After setting the fire, keep the stoking door
shut all the time. As soon as the wood flares up properly, use the air supply regulators to set not very
intensive, rather slow burning. To adjust the flame and the burning, you may apply the information
specified in the Technical Card or Chart 1.
You may poke the fire when needed, using the fire hook or the poking lever (if installed).

Caution! The stoking door (the firing chamber) and the ashpan door (if installed with your
particular model) must be kept shut all the time, except setting the fire, fuel reload or ash removal.

Caution! After every standby for a longer time, before you set the fire again, check the fireplace
insert for clearness and cleanness of the smoke flue, chimney and firing area.

5.3. Feeding the fire

To prevent the smoke spreading throughout the room during the fire feeding, the following is
recommended: Approx. 5 to 10 seconds before you open the stoking door, open the primary air
regulator wide. Then, open the stoking door a bit only, wait for a couple of seconds to allow the
smoke exhausting through the chimney. After that, open the door wide. Pay attention to the door any
time you open it: do not allow live cinder fall out. When you reloaded the wood, shut the stoking
door. When the fuel burns up (no carbon black flame) , bring the regulating system back in the
previous position (or close the regulator, respectively). While feeding the fire, make sure the wood
does not exceed the level of the fireclay (vermiculite) lining within the firing area. The quantity of the
fuel reloaded should be more or less the same as specified in the information provided about the
hourly consumption for the particular model of the heating device (see the Technical Card). If you
overload the stove with excessive fuel, you may cause permanent damage to the insert construction.

Caution! If you want to avoid unnecessary smoke spreading throughout the room during the
feeding, reload the wood after the previous load has burnt up to cinders.

5.4. Glass cleanness

The cleanness of the transparent glass depends on the type of the fuel, proper combustion air
supply (this is applied especially to the secondary air) , the chimney effect and – last but not
least – on the way how the fireplace insert is operated. It is recommended to load one layer of the
wood only: the logs should be laid evenly, farther from the glass (as far as possible). The rule is the
same for coal cakes as well (keep the distance 5 to 0 mm between them). If the glass is dirty, we
recommend to increase the firing intensity by opening the primary air regulator, which usually
supports the self-acting cleaning process.

5.5. Operation during temporary period and at worsened weather conditions

For temporary periods , for example, during the time when outdoor temperature is above 15

o

C,
during rainy and wet days, in case of gusty wind, etc. the chimney effect may worsen thus the smoke
is not led away in full as usual. Therefore, during such period, you should operate the fireplace
insert with smallest possible quantity of fuel, to allow improving the firing process and the chimney
effect by opening the air inlets in case you need to make adjustments.

5.6.

Fireplace insert function adjustment

Some models are provided with the so-called blind element that serves as the chimney effect
conditioner as well. After removal of such blind element, those models must be completed with
warm-water exchanger allowing connection to heating bodies to provide heat in adjacent rooms or
with a water back boiler. A warm water exchanger may be supplied as special accessory (detailed
instructions for operation and installation provided). Order the installation of fireplace insert with
warm water exchanger at specialist company (ask for installation following from the project
documentation).

Caution! A fireplace insert equipped with a warm water exchanger must not be operated
without the connection to the warm water distribution system or the water filled, or without
anti-freezing mixture, respectively.

For any installation of warm water pipeline, the requirements on heat systems and
networks in buildings valid in the country of installation must be adhered to.

Related regulations:
Heat systems in buildings – Safety devices
Heat systems in buildings – Design and installation
Heat systems in buildings – Hot water production
Heat systems in buildings – Designing hot water heat systems
Heaters using fossil fuel designed for dwelling space
Built-in heat devices and stove inserts using solid fuel

Caution! If you install a fireplace insert with a warm water exchanger, before lining and
before first fire, you must connect the exchanger in the heating system operated in order to
check the warm water distribution system for leak.

5.7. Ash removal

Depending on the length and the intensity of the firing process, you need to use a fire hook or poking
lever (if installed with the particular model) in order to knock the ash down the grate to the ashpan.

Monitor the content of the ashpan - do not allow too much ash in it. Excessive ash may block
the air supply under the grate thus causing problems at fire setting or burning.

Always empty the ashpan when cold. The best approach is to empty the ashpan just before you start
preparing the next fire. With some models, the ashpan is located just under the grate

(impossible to take it away on the side). If this is the case, empty the ashpan only if cold,
while the heating system is not in operation. Ash from wood may be used for composting or for

fertilizing.

Caution! Before you touch the ashpan to empty it, check it for fire brand. Prevent any likely
fire in the dustbin.

6. CLEANING AND MAINTENANCE

6.1. Cleaning

The fireplace insert (cold) needs cleaning at least once a year (after the season), or twice or more (
if needed). During the cleaning ,you should remove any dirt caught in the smoke flue, the firing area
and on the partitions. Loose parts of the fireclay lining should be repaired (i.e. replaced). Check the
fireclay lining for integrity even during the heating season. The gaps between the brick shapes are
designed for heat dilatation, to avoid brick cracking. Therefore YOU SHOULD NOT fill any sealing in
the gaps (as it used be before with older heating devices).

Cracked fireclay bricks do not lose the function unless they are completely fallen out of the
position!

In the course of the cleaning procedure, we recommend you to remove all movable partitions (for
easier access in the area above them). To clean the glass, apply standard cleaning agents designed
for cleaning stove, cooker or oven. Use a soft cloth or paper, or special agents designed for cleaning
fireplace glass.Only clean the glass when cold. For cleaning the painted surface, never use water: it
is recommended to clean such surface with sponge or soft flannel cloth.

Caution! With selected types of fireplace insert, the vertical side of the firing area is provided with
VERMICULITE. The same material is used for some chimney effect conditioners. The material is
irreparable. In case of any damage, just have it replaced. Vermiculate products are characteristic
with top heat-insulating parameters and good resistance to cracking. The resistance to abrasion is
somehow lower so it is recommended to keep this in mind while reloading and cleaning.

6.2. Sealing lines and tapes

Contact areas of doors and glass (or other parts of the heating device) are provided with a special
glass-ceramic sealing line (tape) that is resistant to high temperatures. We recommend you to check
the tape for integrity, and have it replaced if necessary.
After some time, any newly installed sealing tape lays flat so it is recommended to check the
tightness (the glass tightly installed in the door construction) after approx. 3 months of usage. If you
find any release, tighten the glass holders (carefully!)

6.3. Spare parts
In case of repair, use only original spare parts recommended by the manufacturer, see Chapter

10.3 (Recommended spare parts). Identify the spare part with use of the Technical Card (a part of

the supply).

7. WHAT TO DO IF... ...Do you do it yourself?

Problem Cause Corrective action

Chimney or smoke flue sealing
(malfunction, “false” air is being
added).

Contact a chimney sweep (ask them to check the
chimney). For example, new sealing for the chimney
door is needed. Adjust the positions of smoke pipes
or replace them if damaged.

Chimney effect bad or not
working

Ask the chimney or stove specialist technician for
inspection to find out the reason and the solution
(e.g. cleaning the chimney, remove the smoke flue
reduction elements, higher chimney, more air in the
room, etc.

The door of another heating
device connected to the same
chimney is open

Shut the door

Chimney cleaning holes are
open

Close the cleaning holes

Smoke flue elements or other
parts of the heating system are
dirty or clogged.

See 6.1.

Insufficient fresh air supply See 4.7.
Worsened weather conditions See 5.5.

Malfunction (weak fire, weak chimney effect) or excessive smoke

during reloading or during the firing

Wrong type of fuel was used for
burning

Provide proper kind of fuel, see 2.2.

Wrong position of the wood logs
inside Not enough fuel to set fire

Add more logs, see 5.2.

Impossible to heat up

the fireplace insert

within expected time

Primary air supply inlet is closed Open the primary air regulator or turn down the

secondary air regulator, respectively

Inadequate requirement on the
heat capacity (performance of
the fireplace insert is too low)

Contact the specialist Reduce the heat loss (for
example, provide better heat insulation)

Smoke flues and insert are dirty See 6.1.

Chimney effect is too low See 4.

The room is not heated

enough

Fireplace insert is operated in a
wrong manner

Heating device adjustment is not optimal, see 2.1.

clean the device outside

Sometimes is difficult to find the
reason but, usually one of the
following is found: wrong type of
fuel, wrong adjustment of the
firing process, weak or
temporarily weak chimney effect,
door sealing loosen

Rule: Clean the door from time to time (depends on
the type of the fuel used), see

5.4.

. If coal cakes are used, the door needs cleaning

more often than with wood
Chimney effect is too low See 4.
Too much fuel in the firing area Only load correct quantity, see 2.1. and5.3.

Window is getting dirty

Wet fuel was loaded Use only well-dried fuel, see 2.2.

8. FREQUENT PROBLEMS AND QUESTIONS

8.1. Cracked (released) fireclay (vermiculite) brick in the burning area

It is emphasised that cracked fireclay bricks do not lose their function unless they have fallen out, so
there is no reason to replace them while cracked only. In case of replace needed, order the
components at your sales representative or manufacturer’s address. Please specify the type and the
serial number and the fireclay ID number (see the Technical Card).
Procedure If you need to replace the side bricks, remove the upper partition or remove the fireclay
holders and take the damaged brick away. Sometimes, you need to remove the cast grate with
bricks at the bottom. For the installation, use the same procedure (reverse). Make sure you place the
components back in exact positions (follow the Technical Card).
Caution! Do not put the stove in operation if (even a part) of the lining within the burning area falls
out. There is danger of burning the construction through.

8.2. Broken glass
The door glass is made of special glass-ceramic material, characteristic with top heat resistance. Do
not use standard window glass!

Procedure: There is no need to dismount the whole door. You should only unscrew the holders and

remove the glass then easily. When you install the new piece, make sure the new glass is seated
evenly. The contact surface between the glass and the door must be provided with a sealing tape.
Do not replace the sealing tape if it is in good condition. Tighten the glass holders back slowly and
carefully to avoid cracking the new glass by excessive tension.
Caution! Some types of the fireplace insert are not provided with the sealing tape along the whole
perimeter.

8.3. Partitions to control the chimney effect
To clean the insert or replace fireclay (vermiculite) bricks, first remove the movable partitions (if
installed, see Technical Card) . This way, you make you way to the cleaning or replacement job.

Keep in mind that some types of the partitions are designed for holding the bricks at the position as
well. Make sure you do not tilt them or let them fall out and break. Install them back in their original
positions.

Disassembly: Lift the movable partition on one side a bit – this way, the other end is lowered. Move
the partition aside to allow taking it out of the device.
Assembly: Use the same procedure (reverse order). Insert the partition into the device and find the
previous position. Check the final position with the Technical Card!

13 14

8.4. Blind element substituted with exchanger (optional)
Disassembly: Use a wrench (proper size) to unscrew the nuts from the blind element. Remove it

from the insert construction.
Assembly: Before you install the exchanger, carefully clean the contact area. Remove any

remaining parts of the previous sealing after the blind element has been taken away. Provide
undamaged sealing under the exchanger. Tighten the nuts evenly to provide good tightness along
the whole exchange flange.
