7.5. Residual risks and preventing them
The risks arising from the use of the boiler under anticipated conditions and logically predictable incorrect use
have been minimized by available technical means.
Despite implemented construction and technical measures some residual risks are still present during the
boiler operation. These residual risks arise from analysis of risks determined by the technological process
during the various stages of the service life of the product.
These include in particular the risks of lack of concentration by the boiler user and failure to observe
safety precautions during operation.
To further reduce the risks and ensure greater security efficiency attention is drawn to possible occurrence of
residual risks that cannot be eliminated by any technical solutions.
a) Electrical risks
▪
connection, maintenance and repair of electrical parts of the boiler must be carried out only by
qualified personnel in accordance with applicable technical regulations and standards
▪
the electrical wiring must comply with applicable regulations
▪
the power cable and wiring of the boiler must be regularly checked and maintained at required
standards
▪
should there be any damage to the electrical part, the boiler must be shut down, disconnected from
the power supply and a repair by a qualified person must be ensured
▪
it is forbidden to interfere with the security circuit connections or tamper with parts that ensure safety
and reliability of the appliance
b) Thermal risks
▪
the boiler must not be exposed to higher operating pressure than specified
▪
it is forbidden to overheat the boiler
▪
the boiler must be protected against low-temperature corrosion by appropriate connection with
automatic return temperature protection
▪
only specified fuel can be burnt in the boiler
▪
it is prohibited to store flammable materials in close vicinity of the boiler
▪
when operating the boiler maximum attention must be paid to the risk of burns caused by heat source
c) Risks caused during fuel manipulation
▪
Solid particle emission occurs whilst handling the fuel. It is therefore recommended to use
appropriate protective equipment according to the dustiness of the fuel.
▪
relevant fire regulations must be followed and a suitable fire extinguisher must be available
d) Ergonomic risks
▪
the boiler must be positioned in the boiler room horizontally
▪
it is forbidden to reach into the screw feeder
▪
during boiler operation all doors, lids and covers must be closed properly
8. Boiler maintenance
The boiler maintenance can be carried out only by a trained authorized service company that is
familiar with these instructions.
1.) It is necessary to re-fuel the store in a timely manner. If there is only small amount of fuel remaining in
the store it must be immediately re-
filled to avoid „fake“ air intake or smoke entering the fuel store.
Attention needs to be paid so the fuel store lid is closed properly!
2.) If the boiler is set up correctly, the fuel is completely burnt when it reaches the edge of the rotary part of
the burner. The ash then falls into the ash drawer. The combustion chamber is self-cleaning and the ash
drawer needs to be emptied on average once a week if the boiler operates at average output (safety
gloves must be worn). Occasionally, a piece of slag might get stuck on the edge of the rotary part of the
burner. It is then necessary to remove it by using the rake.
