3.2. Safe distance bet ween the fireplace i nsert and flammable materi al
If you have installed a fireplace insert within the room with flammable objects, flammability Class B,
C1 a nd C2, t he safety d istance from the front (or side g lass surfaces) is 8 00 mm; f or the o ther
directions, the safety distance is 400 mm . If the insert is i nstalled within a room w ith flammable
objects, flammability class C 3, the safety distances m ust be doubled . Kindly pay a ttention to the
information provided in Supplement 1 and 2. The most important installation dimensions are
shown in the product name plat e.
3.3. Safe distance bet ween the smoke flue a nd flammable mater ial
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 appl ied to construction m aterials, flammable Class B, C1 and C2. (see Chart 3).
Kindly pay attention to the information provided in S upplement 2. More accurate classification is
available only if testi ng is performed for the particular product.
3.4. Directions for safe operation
For firing or kindling, never use any flammable liquid! It is fo rbidden 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 o nly! Never allo w children in the room unattended. The
surface of the fireplace insert is o verheated, 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 b e 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 f ireplace i nsert m us t b e o perat ed i n c o mpliance with t he d irections a nd

4. INSTALLA TION AND CONNECTION TO TH E CHIMNEY
Caution! For i nstallation, relevant local regulations must be strictly adhered, including the
regulations related to nati onal and Europea n standards for thi s type of dev ice.
4.1. Connection to the chimney or chimney insert
Connection of the fireplace insert to the chimney vent is subjected to approval by speci alist chimney
company (Č SN 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 p roper 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 malfunct ion of t he 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 w hile proper c himney draught i s not pr ovided, flue g ases may s pread 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 ef fect is too high (over
20 Pa) it is recommended to install a suitable blocking device (for example, flue tube with a block).
Excessive c himney d raught may cause troublesome oper ation, for example, too inten sive b urning,
high fuel consumption , damage on the heating device, etc.
Caution! I t is recommende d to c onnect fire place inserts wi th rear o utlet t o the c himney 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 chim ney vent. A joint chimney
vent may be used for the co nnection only if the sa fety regulations valid in the country of
installation allow doing so . It is forbidden to connect th e stove (stove insert ) to the same vent
used for a gas appliance. The minimum working height o f the vent is 5 m . Depending on local
conditions, it is possible t o connect the stove in the ve nt with a working hei ght under 5 m
providing that the flue way calculation dem onstrates that such a height is sa tisfactory.
Caution! (Provisions CSN 7 3 42 01: 2008)
The smoke flue vent diam eter must not exceed the diam eter of the chim ney vent; it must not
be narrowed towards the chim ney, either. If the calculati on demonstrates that the vent
diameter of the smoke flue an d chimney can be sm aller than the flue neck diameter of the
device, the diamet er of the smoke flue will be reduce d just after the flue neck of the device, by
means of a short transiti on or abrupt.
4.3. Directions for smoke f lue installation and safety
Connect the smoke outlet neck w ith the chimney in the s hortest possible way so that the length o f
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 m m. Pay special attention to t he fact that the jo ints must agree
with the flue outflow. The joint between the smoke flue and the smoke outlet neck must be drilled
together and fixed w ith a rivet o r pin; the s ame is a pplied for the smoke p ipes and the e lbow. T he
hole (entrance point) in the c himney must be provided w ith a metal stress ring ( proper d iameter).
The smoke flue should ascent towards the sm oke 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 f loor (ceiling) load capacity. T he load
conditions for the part icular type of t he device must be m et (depending on the p articular 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 g round plan dimensions on the
sides and i n the rear b y at least 4 00 mm; the o verlap in the f ront (the direction of t he feeding
opening) is 800 mm. If a metal base is used, t he thickness must be at least 2 mm.
For safet y distances from the outer surfa ce of the insert body a nd 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 pur pose of cleaning.
