attention to the condition of the gaskets and replace them before or after each heating season or if
you notice wear.
ASH REMOVAL
Ash should be removed before each start-up of the cooker. If the cooker is not in regular use the ash
should be removed after lighting and cooling down of the cooker.
This is done by emptying the ash container located below the grate. The ash should be emptied regu-
larly to prevent ash falling out of the firebox. Do not allow the ash to fall over the hurdle. Ash should
be removed from a cold cooker.
SELECTED MODELS WITH TILE OPTION
Tiles - Due to the manufacturing process, tiles have unique characteristics for each production batch.
Therefore, they may show slight discolouration, shade differences or hairline cracks on the surface.
These features do not constitute a defect and do not affect the function of the product. Nor can they
constitute grounds for a complaint about the cooker. When storing, transporting and installing the
tiled stove, it is absolutely necessary to protect the surface of the tiled covering from mechanical da-
mage.
CONSERVATION OF TILES
Use a dry cotton cloth or paper towels to clean the tiles. Do not: spray detergents on the tile surface
and use a damp cloth (especially on a warm cooker).
Moisture can make the small hairline cracks on the ceramic surfaces more visible, especially on light
colours, this action can also cause joints to crack. It is forbidden to use abrasive materials that are sharp
and can scratch the surface of the tiles, as well as caustic agents.
Note: Any maintenance work must only be carried out when the appliance is in a cooled state.

be due to improper installation of the appliance without observing the applicable building regulations
or the provisions of this manual, or for independent reasons, such as the environment.
The most common causes of malfunction of the appliance are listed below, together with
how to solve them.
a) Smoke retreat with door open :
- opening the door too rapidly (open the door slowly); close the primary air damper
- if a flue pipe is fitted as a draught regulator, open the flue pipe every time the door is opened;
- inadequate air supply in the room where the appliance is installed (ensure adequate ventilation in
the room or supply air to the combustion chamber in accordance with the instructions in the manual
if this is possible for the model selected);
- atmospheric conditions: low pressure, fog and precipitation, rapid changes in temperature;
- insufficient draught (have the flue pipe checked by a chimney sweep).
b) Phenomenon of insufficient heating or extinction :
- low amount of fuel in the firebox (load the firebox according to the instructions);
- too much moisture in the wood used for combustion (use wood with a moisture content of up to
