Installation, start-up, maintenance
7. Equipment to be operated only with
safety devices activated and in good
working order.
8. The system must be checked
annually – or more frequently if
necessary, depending on system
conditions - for externally visible
damage and for the correct operation
of safety devices.
9.Safety functions and safety times
must not be impaired, rendered
inoperational or modified by additional
external wiring.
Tasks carried out on the electri-
cal system
• All tasks involving the electrical
system must be carried out by expert
electricians.
• Before any work is carried out, the
system must be disconnected from
the power supply and secured against
unexpected reconnection.
• Work on live systems may only be
carried out under the supervision of a
second person who would be able to
disconnect the power supply in the
event of danger.
• The electrical system must be
routinely checked as part of
maintenance. Damage of any kind
(e.g. loose connections, damaged
cable insulation) must be rectified
immediately.
Safety instructions for assembly
Always disconnect the system from
the power supply!
Before assembly work begins, switch
off the master and emergency switches
and secure them against the possibility
of being switched back on.
Danger!
Failure to comply could result
in a harmful or fatal electrical shock.
Risk of severe injury and danger of
death.
Safety instructions for initial
commissioning
The initial commissioning of the heating
installation must only be carried out by
the constructor, manufacturer or
another of the experts described. All
regulating, control and safety devices
must be checked for correct operation
and – where adjustment is possible –
for correct adjustment.
Before initial commissioning, it is
necessary to check electrical circuits for
correct fusing, and the measures for
protection against accidental contact
with electrical equipment and wiring.
Safety instructions for
maintenance
• The operator must be informed of all
work to be carried out before it begins.
• Assembly, commissioning /
adjustments, repair and maintenance
carried out only by experts trained and
authorised for the work concerned.
This also applies in particular to work
on the electrical system and the gas/
oil supply.
• Protective clothing must be worn while
work is being carried out on the
system.
• Specified adjustment, maintenance
and inspection work must be carried
out at the specified intervals.
• Before any work is carried out on the
system, the system must be
disconnected from the power supply
and secured against unexpected
reconnection.
• The fuel supply must be closed before
work is carried out on the system.
• All safety devices of the system must
be checked on a regular basis as
specified by national requirements,
regulations, standards and legislation.
• Damaged system parts must be
replaced immediately. If parts are to
be replaced, it is only permitted to use
genuine parts, or replacement parts
that have been approved or
authorised by the manufacturer.
• The installation of additional
components that were not subjected
to model series or individual testing at
the same time as the system is not
permitted.
• Do not modify the system or fit
attachment or conversion parts
without the authorisation of the
manufacturer.
• Loose connections must be checked
for firm seating after they have been
reconnected.
• If seal connections are opened, the
sealing surfaces must be cleaned
thoroughly at the time of reassembly.
Ensure a perfect connection;
damaged seals must be replaced with
new ones. Check for leaks once
reassembly is complete.
• Repairs to limiting devices, automated
equipment, flame monitoring
equipment and other safety devices
must only be carried out by the
manufacturer or its appointed
representatives. The expert charged
with carrying out maintenance work
must replace complete components or
assemblies with those of the same
type.
• Safety devices must be checked for
correct operation following their
replacement or repair and after any
maintenance work has been
completed.
• Only use the burner with furnaces that
are suitable for the flame dimension
concerned, i.e. in which the flame may
burn out unhindered.
• Any change to the furnace pressure
(e.g. as a consequence of
modifications to the flue system), and
any modification that would result in a
change in the supply of air to the
burner (e.g. a retrofitted
soundproofing shroud), requires
reconfiguration of burner regulation.
• Persons present in the proximity
during burner operation must be
equipped with suitable measures for
protection against harmful noise
levels.
After all maintenance and repair
work:
1. Function test.
2. At all load points, check O
2
- (CO
2
-) /
CO -/ NOx- values, soot emissions
and exhaust gas losses.
3. Create a measurement report, leave
a copy with the system.
