WARNING:
The solid fuel must not be used without water. It must be connected to an installation on which consumers (radiators) are
connected with a minimum power of 8 kW.
When the system is cold, the flap of the power regulator (combustion regulator, thermostat) located in the ashtray door
(fig.1 pos.10 and pos.19) should be open. Pull ahead the butterfly knob for opening and closing (fig. 1 pos.4 and fig. 16). That
way the butterfly knob is open and kindling is enabled. Later when the solid fuel is inflamed, we adjust the regulator flap on the
appropriate position that depends on the pulling power of the flue and the desired power, and the butterfly knob should be
pushed back. Then the butterfly knob is closed and full use of the combustion is enabled, thus better heating, cooking and
baking. During this, the door of the firebox and the ashtray (fig. 1 pos. 7 and pos. 9) must be closed if we want regulated
combustion. The butterfly knob for kindling is open only during the kindling of the solid fuel (10 to 15 minutes).
The firebox and ashtray doors can be open and closed manually, as well as with the bent wrench as shown on figure 6.
We stoke the solid fuel as all permanently burning solid fuels on solid fuels. When the grade is in lower position, we
perform kindling through the open door of the ashtray and the ember holder (fig.9 and fig.10). We open the ember holder (fig.1
pos.13 and fig.9) by raising and pulling. When the grate is in upper position through the open door of the firebox (fig.11) on the
grate we put paper, small pieces of chopped wood and kindle. When everything is burning well, we can fill the solid fuel with
wood if the grate is in upper position. If the grate is in lower position, do not put at once all the needed heating material for full
firebox, but divide it on two or three parts and put it in the firebox at intervals of 10-15 minutes on flaming heating material.
The solid fuel filled in this manner burns from 1 to 6 hours, depending on the intensity of combustion in the solid fuel and the
adjusted power regulator (thermostat).

The firebox can be filled from the upper side as well (fig.12). The cover is lifted by using a wrench and firewood is put. It is
not recommended to put some organic waste in the solid fuel (plastic bags, bones etc.) because in this case tar collects on
the walls of the flue channel and this can cause a fire.
After every filling it is recommended that the solid fuel burns with maximum power for at least half an hour since in the
beginning all volatile compounds in the fuel burn, which are actually the main causes for condensate creation in the solid fuel.

10. GRATE USE IN UPPER AND LOWER POSITION
For cooking, baking and frying in the transit period, the upper grate position is used (fig.11) so that the flame could directly
reach the hob thus saving the costs for cooking, baking and heating.
The solid fuel is delivered with a grate in lower position. In order to move the grate from the lower to the upper position, it
is necessary to do the following:
- Remove the hob from the solid fuel and open the door of the firebox and the ashtray.
- The grate should be pushed completely back with a rod for shaking the grate and then through an opening of the ashtray
door and the space for ash and the front part of the grate should be lifted by hand and should be pulled out from its bearing
(position). After this, the carrier of the grate is lifted and pulled out.
- The placement of the grate in upper position is performed in reverse order. The grate carrier is placed on the grate
holders (pieces 4) welded in the boiler firebox in front and on the back side (pieces 2+2) (fig.1 pos.23). In the grate carrier
