Conditionally, it is permitted to burn certified wood briquettes made from sawdust or pellets, however
in small quantities only.
Practical evaluation of the moisture content of wood fuel used is as follows. Wood which is to have
moisture content in the range of 18-20% must be seasoned for a period of 18-24 months or be subject
to drying. With the reduction of moisture in the wood, the calorific value increases, which means cost
savings - up to 30% of the total mass of wood needed for one heating season. Using wood with too
high moisture content, excessive consumption of energy needed to evaporate the moisture may be
needed and condensate may be created in the flue or the combustion chamber, influencing the space
heating.
Another negative phenomenon observed with the use of wood with too great moisture content is the
phenomenon of the generation of creosote - sludge being destructive to chimneys, which can cause
inflammation and fire of the chimney.
Therefore, it is recommended to use hardwood oak, beech, hornbeam, birch. Conifers have lower en-
ergy values and using them causes intense soot on the glass.
NOTE: Do not use the fireplace insert when it is not trimmed, except for the test firings.
STARTING THE FIREPLACE
Before trimming the fireplace, conduct a few test ignitions, during which you should check the opera-
tion of the vent and other moving parts of the insert. Newly installed fireplaces must be operated with
the power of approx. 30% of the nominal power in the first two weeks of use, with the temperature
gradually increased. This way of the use of the insert enables gradual removal of internal stress, thereby
preventing thermal shocks. This has a very significant effect on the later performance of the insert.
During the first few startups, the insert can emit the scent of enamel, silicone sealant and other materi-
als used to perform the installation. This is a normal phenomenon which disappears after a few cycles.
OPERATING THE FIREPLACE
In order to start a fire in the fireplace insert, open the insert door using the handle, place the kindling
on the grill (dry paper is recommended), lay shredded wood on it and then wood logs. We do not rec-
ommend the use of synthetic firelighters because they contain chemicals which can give off specific
odours.
Then open all the inlet holes in the front ash pan and ignite the kindling and then close the front door
of the fireplace.
NOTE: It is forbidden to use other materials than those provided in the instructions. Do not use flam-
mable chemical products to ignite, such as oil, gasoline, solvents and others.
After the fire is ignited, the wood burning chamber of the insert should be filled with fuel in a way
that fits the chamber appropriately for the specified firing time on the basis of individual experience.
During burning, the fireplace insert front door is to be closed. Prolonged maximum combustion tem-
peratures can lead to overheating of cast iron components and damage. Consequently, the intensity
of the fuel combustion process in the fireplace insert should be controlled by the rotary vent speed
control that is in the flue pipe of the fireplace and the corresponding apertures in the ash pan. Control
the level of filling the ash pan tray with ash, as in the case of excessive levels, cooling the grate is limited
and the flow of combustion air is limited. To empty the ash pan drawer, slowly open the front door, pull
out the drawer from the fireplace insert and empty it, keeping in mind the fire regulations.
NOTE: During all activities related to maintenance and operation of the insert, remember that the
parts of the insert may have high temperatures and therefore protective gloves should be used. During
operation and use of the fireplace insert, stick to the rules that assure the basic security conditions:
• Refer to the owner's manual of the fireplace insert to strictly observe its provisions;
• The insert must be installed and ignited by an installer having appropriate qualifications;
