The firebox can also be filled from the cooktop (Fig 12). Lift the cooktop lid using a wrench and load the fuel.
It is not recommended to burn organic or other waste in the stove (plastic bags, bones, etc.) because this causes
formation of tar deposits on the flue duct walls, which can cause a fire.
Each time you load the fuel, we recommend that you let the fire burn at maximum strength for at least half an
hour, because the first to burn out are all the volatile constituents of the fuel that are usually the main causes to
condensate formation in the stove.
After plenty of hot fragments have formed, load the portions of coal in two or three steps at 15 minute intervals.

9. USING THE GRATE IN THE UP AND DOWN POSITION
For cooking, baking and heating during transitional season, the grate is in up position (Fig. 11) to ensure that
the flame directly reaches the cooktop and saves cooking, baking and heating costs.
The stove is delivered with the grate in the down position. To move the grate from down to up position, take the
following steps:
-
Remove the cooktop from the stove and open the firebox and ash pan door.
-
Use your hand, through the ash pan opening and ash pan, to lift the front of the grate and pull it out of
its holder.
-
Place the grate on the supports (4 pcs) welded inside the boiler firebox, at the front and in the back (2 +
2 pcs) (Fig. 1, Item 23). Place the grate at an angle (slanted) so that the back of the grate can be fitted
first, and then lower the front of the grate. Put the cooktop back on the frame.
-
The grate is placed in the down position (Fig. 9 and 10) the same way as it is placed in the up position.
Notes:
-
Grate in the down position enables better heating of water, heating more radiators and larger living
areas, but cooking is more difficult.
-
When the grate is in the up position, water is less heated, and less radiators and a smaller living area
can be heated, but cooking is much easier.
-
Baking is the same in both positions of the grate.
10. AUTOMATIC REGULATION
Stove power is adjusted using the thermostat (power regulator, combustion regulator), which is located in the
ash pan door and which automatically sets the regulator damper depending on the regulation knob setting (Fig.
1, Items 10 and 19) and the temperature of water in the boiler. Regulation knob has several positions that are
written on the knob as specified in Table 1:

In the power regulation system, air regulator (damper) fully controls combustion air supply if other openings
are closed.
