4.4. Refuelling
The container should be refuelled regularly to maintain contin-
uous operation of the boiler. Fuel should be added when the
coal layer in the container reaches height min. 30 cm from the
bottom of the container - at the latest. Smoke and dust may be
emitted from the container in case of too low fuel amounts. If
there is no fuel the controller will shutdown whole system and it
will be necessary to
fi re up a boiler. To refuel:
1. Turn o ff the fan.
2. The open fl ap of the fuel container.
3. Add fuel to the container.
4. Make sure that there are no contaminants, which can lock
operation of the feeder (debris, rocks, parts of wood metal).
5. The close tightly fl ap of the container.
6. Switch on the fan.
NOTE! During operation of the boiler fuel container should
be always tightly closed!
4.5. Stop of boiler operation
1. Switch to manual mode.
2. Turn o
ff the fan and feeder.
3. Switch on the fuel feeder in manual mode for several min-
utes, taking a considerable amount of fuel out, to remove
whole heat from the burner.
4. Switch o ff controller.
5. Close tightly all doors, fl aps, damper on fl ue to damp the
system.
6. After dozen or so minutes check whether the fuel has not
reignited.
7. Remove residues of coal and ash from the boiler if the heat is
completely extinguished.
8. Remove remaining fuel from the container and feeder.
4.6. Boiler shutdown when the heating season is fi nished
To shutdown the boiler after the heating season you should
repeat operations listed in the
Stop of boiler operation and then:
1. Remove fuel from container and feeder.
2. The clean whole boiler from inside,
fl ue gas ducts and
chimney.
3. Leave open doors and lifted the cover of fuel container dur-
ing standstill of the boiler to dry boiler interior and ensure
continuous air
fl ow.
4. Commission execution of inspection of boiler condition.
NOTE! Do not drain the water from boiler and heating sys-
tem when the heating season is
fi nished or during breaks
in heating (except time necessary for possible repairs). It
protects boiler against accelerated corrosion. However, it is
necessary to drain the water from the system if break in
boiler heating occurs during frosts. It will prevent freezing
of water and damage of the system.
4.7. Cleaning and maintenance
Maintaining cleanness of the boiler is a necessary condition for
its e
ff ective, trouble-free operation. Even small layer of deposit
will cause decrease of heat transfer from fl ue gas and reduces
boiler e ffi ciency as a result. It can be also a reason for boiler
damage.
Therefore, the boiler should be regularly and precisely
cleaned at least once a week. After shutdown and cooling down
of the boiler you should: 1. remove ash from combustion cham-
ber and ash-pan, 2. remove soot from combustion chamber and
ash-pan using wire brush, 3. after opening of upper and bottom
