Automatic boiler for pellets – User manual

3) Cleaning of the heat exchanger
Cleaning itself is done by intensively swinging the lever on the side of the boiler back and forward at least 20
times.
Anticipated interval: …………………………… after burning approximately 200 kg of fuel or once a
week
Note:
This applies to the boiler equipped with a semi-automatic heat exchanger cleaning. It is also necessary
to pay attention to cleaning the surface of the burner while doing the heat exchanger cleaning, in order to prevent
the burner's air holes from clogging up.
4) Cleaning of the ceramic grate (fig. 5)
Is achieved by rotating the component by 90° when it is cooled down. After the dust particles fall out, place the
ceramic parts carefully back in place.
Anticipated interval: ……………………………………once every 2 months
Note:
Carry out the cleaning when the temperature of combustion products exceeds 220°C.
2.2 FILLING THE FEEDER F1 WITH PELLETS
Check if the feeder is filled with prescribed fuel.
Filling the fuel transportation ways with fuel:
- the boiler has no system to detect amount of fuel in the burner.
- Boiler operation is controlled by time sequences which are set in the operations of feeders F1 and F2.
- To ensure proper boiler functionality, the feeder F1 has to be filled with fuel to a degree that the fuel
starts fall out from the feeder into the connecting hose prior to initial start of the boilers operation.
- Consequent filling of the conveying routes is done automatically, provided that the amount of pellets in
the bin is sufficient.
- The conveying routes shall be filled by operating F1 and F2 feeders, see MENU 1.1, 1.2 (chapter 5.3.1 -
Direct control)
2.3 BOILER IGNITION - ELECTRIC IGNITION
For application of electrical ignition it is
necessary
for the boiler to be equipped with a burner furnace with a
heating coil that is used to ignite the pellets, the electric ignition also has to be enabled in Menu 6.
We ignite the boiler by pressing the START button. The display will show the following notice:
> ON <
-Elect. light up-
> START! <
We confirm the commencement of the ignition sequence by pressing → ENTER.
The boiler will commence an automatic ignition sequence, which is indicated by a flashing sign AUTO.
Operation of electric heating coils is indicated by a flashing sign >I<.
Note:
Progress of the electric ignition proceeds according to timing parameters set up by a service engineer
when the boiler is started up.
Note:
If the electric ignition process is activated, it will automatically run through to its full extent. This fact is
a very important condition for a reliable operation of the boiler because it is determined only indirectly from the
following behaviour of the boiler whether is it burning or not.
