Operating Instructions and Installation Instructions

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.
