A person operating the boiler should be aware that some boiler surfaces are
hot, and safety gloves must be worn before touching them!
You should also use protective goggles (hot surfaces are marked with a pic-
togram).
Flue gases emitted from an obstructed stack are hazardous. The stack and the
connector should be kept clean; they should be cleaned according to the manu-
facturer instruction. Boiler flue gas ducts should be kept clean.
Use only recommended types of fuel.
Before firing the boiler, load the fuel tank (fuel storage) so it is possible to
close the lid. When fuel is loaded to the hopper check the loaded fuel for sto-
nes, metal components and similar objects that may block the screw conveyor
mechanism. Then switch the controller to
MANUAL MODE*
for a period of time
after which the transport augers fill the feeder tubes with fuel. Then set the au-
tomatic firing process on the controller (ceramic burner). In the boiler automatic
mode, a set temperature (boiler water temperature) value must be set on a con-
troller along with the operating time and intervals in the moving grate operation.
This action should be performed in accordance with procedures specified in
the operating manual of the controlled (Configuration of User Parameters). The
amount of air supplied by the blower fan should be adapted to intensity of fuel
combustion in the furnace.
Monitor the boiler during firing until the water supply temperature reaches
45°C. This is important because the boiler can go off due to varying quality of
fuel. When the fire in the boiler is extinguished, clean the furnace and air the
boiler ducts during firing, and restart firing.
After a single firing the boiler operation is, in general, maintenance free, and
the burning process is continuous. Further boiler operation is limited to reple-
nishing of the fuel tank and removing deposited ash from the ash-box drawer.
