Operation and maintenance
1.3.1
General notes
In order for the system to be
operated and maintained safely, it
must be operated and maintained
properly by qualified personnel
while heeding the warnings in this
documentation
and
the
instructions on the systems.
The system must not be
opened until “HEATING OFF”
is displayed as otherwise there
will be a risk of deflagration
(explosion).
In
unfavourable
operating
conditions, the temperatures of
parts of the housing may exceed
80 °C.
If the door to the ash pan is
opened during operation, the fuel
supply will be shut off and the
boiler will switch to the burnout
phase. After that, it will go into the
operating mode “HEATING OFF”.
1.3.2
Operation
General safety instructions
Covers which prevent contact
with hot or rotating parts or which
are required in order to direct the
flow of air correctly and thus
ensure the effective functioning of
the system must not be opened
during operation.
In the event of a fault or unusual
operating conditions such as the
emission of smoke and flames,
the system is to be switched off
immediately by operating the
emergency stop button. The
HERZ
Customer
Service
department is then to be notified
immediately.
If the main switch is operated on the boiler
room door or if there is a power failure, the
system will be taken out of operation
immediately. The remaining quantity of
residual fuel will burn independently without
giving off any toxic gases provided that the
chimney draught is sufficiently high. Therefore
the chimney must be designed and produced
in accordance with DIN 4705 or EN 13384.
When it is switched on again, the system is to
be checked in order to make sure that it is
fully functional and the safe operation of the
whole system must be guaranteed!
If the residual oxygen content in the flue gas
drops below the minimum of 5% required, the
fuel supply will be stopped automatically and
will not be activated again until the residual
oxygen content has risen to more than 5%
(message displayed: ACTUAL O2 [‰] 50)
The noise generated by the machine during
operation does not present any danger to
health.
1.3.3
Maintenance
General safety measures
Before starting to carry out any work on the
system, but especially before opening covers
protecting live parts, the system is to be properly
disconnected from the power supply. Besides the
main circuits, attention is also to be paid to any
existing additional or auxiliary circuits in the
process. The normal safety rules according to
ÖNORM are:
Disconnect all poles and all sides!
Ensure that the system cannot be switched on
again!
Check to ensure that no voltage is connected!
Earth and short-circuit!
Cover
adjacent
live
parts
and
locate
hazardous areas!
These
above-mentioned
measures must not be reversed
until the system has been fully
installed and maintenance has
been completed.
Personal dust masks and gloves
must be worn when carrying out
maintenance
work
in
the
combustion chamber or the ash
collector or on flue gas-carrying
parts, when emptying the ash
pan, etc.!
