THE RANGE OF MODELS WITH TILES
Tiles – due to their production process, each individual production batch of the tiles has its unique
features. This can result in minor colour changes, shading or crazing visible on their surface. These
features are not faults and do not affect the functioning of the product. They may not be the basis
for lodging any claims, either. The surface of the tile sections must be protected against mechanical
damage during storage, transport and installation.
TILE MAINTENANCE
Use dry cotton cloth or paper towels to clean the tiles. Do not spray detergents onto the tiles surface or
use damp cloths (especially on the warm stove). Moisture can make the small crazing on the ceramic
surface become more visible, particularly for bright colours, and it can also cause grout fracturing. The
use of sharp and abrasive materials which can leave scratches on the tile surface, as well as corrosive
agents, are not allowed.
Caution: Any maintenance work may be performed when the appliance is in a cooled-down state
only.

SPARE PARTS

If after many years you find exchanging some parts necessary, contact the supplier or any representa-
tive of our company. To order a spare part, submit the information listed in the rating plate located on
the back of the guarantee certificate, which must be kept even when the guarantee has terminated.
If you have this information, and our factory documentation, the supplier will be able to deliver all
spare parts in a short time.
POSSIBLE IRREGULARITIES DURING THE OPERATION OF THE APPLIANCE
During the operation of the appliance there can occur some irregularities which indicate that it is
working improperly. This can be caused either by the incorrect installation of the appliance - without
adhering to the valid construction provisions or the instructions in this Manual, or for reasons beyond
one's control, e.g. the natural environment.
The next section shows the most-frequent reasons for the incorrect operation of the appliance, and
how to remedy such occurrences.
a) Back-puffing when the door is open:
- the door is opened too abruptly (open the door slowly); slide the primary air damper towards the
closed position
- if a flue damper is fitted as a chimney-draught control, open the flue damper each time you open
the door;
- Insufficient air supply to the room in which the appliance is installed (provide adequate ventilation
in the room or supply air to the combustion chamber in accordance with the instructions in the
Manual, if possible for the right model);
- weather conditions: low pressure, fog and precipitation, sudden temperature changes;
- insufficient chimney draught (have the chimney flue inspected by a chimney sweep).
b) Too-low heating, or the fire goes out:
- too little fuel in the hearth (load the hearth according to the Manual);
- too-high humidity of the wood used for burning (use wood with a humidity of up to 20%); a large
portion of the energy obtained is lost in the process of water evaporation;
- insufficient chimney draught (have the chimney flue inspected by a chimney sweep).
c) Insufficient heating in spite of proper burning in the combustion chamber:
- low-calorific softwood (use wood which meets the guidelines in the Manual);
- too-high humidity of the wood used for burning (use wood with a humidity of up to 20%);
- too fragmented wood, too-thick wood billets:
d) Excessive glass-dirt accumulation:
- low-intensity burning (when burning with a very-low flame, use dry wood fuel only);
