The combustion of inferior quality fuels may cause an increased amount of ash
as the product of the combustion process. Furnace cleaning mechanism performs
recurring blows and movement of grates. The combustion of inferior quality fuels
can cause ash build-up on the furnace plate (fixed part). In such a case you must re-
move the furnace housing and remove the ash to the ash drawer. Ash accumulation
is not a defect in the operation of the burner, but a consequence of combustion of
inferior quality fuels. Control of the fuel feeder and blower fan is done automatically
depending on the demand for the heat output. The frequency of the grate moving
should be adjusted depending on the quality of the fuel used.
Any activities related to revision of the auger feeder can only be perfor-
med when the boiler is disconnected from the mains.
When the above recommendations related to boiler cleaning are not obse-
rved, this may result not only in significant heat losses but also hinder flue gas
circulation in the boiler, resulting in turn in smoke emission from the boiler.
Proper maintenance and systematic maintenance prolongs life of the boiler
and its accessories.
NOTICE: At least once a month check the accumulation if dust in the air
chamber (see fig.7, item14), possibly shutoff the boiler and clean the furnace
– the pellet burner.
When the boiler is equipped with a flue gas temperature sensor, its surfa-
ce must be cleaned regularly to ensure correct temperature readouts in the
flue gas pipe, and control over the burning process.
Periodical cleaning of a flue pipe is also of importance for correct operation
of the boiler.
8.4. END OF BURNING
At the end of heating season or in cases of the planned boiler shutdown, switch
off the burner by selecting the
extinguish mode
on the controller and remove the
residues after combustion to the ash box.
NOTICE: It is forbidden to use water in the boiler room to extinguish fuel!
In the event of the emergency extinguishing, the fired fuel must be removed
into metal containers and removed from the boiler room, or sand should be po-
ured over fuel burning in the furnace.
When the boiler is put off and cooled, remove all residues of burned fuel from
the furnace, and perform cleaning and maintenance operations for the whole bo-
iler. Required maintenance (lubrication with oil) of inner partitions of the furnace
chamber and moving components should be performed.
Do not discharge water from the boiler and the system for the break in the
heating season. If the boiler has been excluded from the work, the feeder mecha-
nism, moving grate, blower fan and circulation pump should be run once a week.
This prevents jamming the moving parts.
