Combustion air flow

Operation
1.
After reaching the heating water temperature, adjust the combustion air supply. Output control is made by the choke on the stoking door
which regulates the air supply over the fuel by means of the draft regulator or adjusting screw of the choker. The draught regulator has to
be adjusted so as the choker of the stoking door is slightly closed at 3-4 mm at the moment the desired temperature of heating water is
reached.
2.
According to heat needs and burning intensity, it is necessary to refuel during the boiler operation. Hot layer suitable for adding the fuel is
about 15 cm. Before adding the fuel, make manual cleaning - from below, through a hole in the lower part of the grate, and through the
stoking door for firewood. Before refuelling, release the orifice of the hole in the bottom part of the lining of the combustion chamber so as
to allow continuous fuel burning off. Max. fuel filling height is determined by the upper edge of the inclined grate.
3.
Before refuelling, it is recommended to open the shorting flap located above the stoking door choker, and after refuelling, close it again.
4.
The ash door must be permanently closed during the operation.
5.
If necessary, clean the ash-pan (the gloves needed).
6.
In case the shut-off valves are installed, the safety valve must be mounted between the boiler and the shut-off valve.
7.
We recommend to clean the filter after the heat test and then before the heating season starting.

Maintenance
1.
Check and if necessary remove ash from the ash-pan because full pan prevents the proper distribution of combustion air under the fuel
and causes unequal burning of the fuel on the grate. Remove all fuel remnants in the furnace and in the burn-off hole before each new
firing. Because of achieving high temperatures during combustion, the lining of the combustion chamber is not clogged and there is no
necessity to dismount it fully. We recommend once every14 days extrusion of its front middle part (see fig. No15 - pos. 7) and clean-up the
space under the nozzle of tertiary air.
2.
The ash must be put into incombustible containers with lids. During the work, it is necessary to use protective equipment and ensure
personal safety.
3.
1x per week, clean the boiler walls inside the furnace, boiler smoke drafts and smoke adapter with a brush (cooled down boiler, the
temperature does not exceed 40 °C). For the ash removal from the smoke adapter, use the cleaning cover at the its bottom part. When
dismantling the cleaning cover, loosed the screw securing the latch to avoid its damage. After cleaning the smoke adapter, mount the
cleaning cover back and pay attention to the tightness of the cleaning cover and the smoke adapter.
4.
If using fuels with higher development of gas leading to tar depositing on the walls of the fuel space, remove it by scraping or burning dry
hard wood (or coke) at the boiler max. operating temperature.
5.
After the heating season, clean the space behind the choker of the tertiary air inlet, treat the pivots of the smoke flap, shorting flaps and all
doors.
6.
Cracks caused by tension or slight corrosion on the refractory lining are caused by temperature fluctuations and the temperature over 1000
°C in the combustion chamber. Decisive for the functionality of the device is the dimensional stability of the components. Cracks do not
affect the functionality and can be considered, similar to the tiled stove, normal.
7.
If there are impurities on the cover parts and control elements, it is best to remove them with a soft damp cloth. We recommend gentle
cleansers without solvents. Solvents such as alcohol, gasoline or thinners should not be used because they could damage the surface of
the device.
8.
We recommend to clean the glass part of the stoking door more often and do not let the creation of the too thick layer of sediment. We
recommend to use products for cleaning glass of fireplaces and stoves. When cleaning, follow the detergent manufacturer's instructions.
