Boiler operation
The equipment goes into operation automatically
when heat is required due to its built-in automatic
ignition.
The heat requirement can be weather-driven, and
can be used in conjunction with a remote sensor
(optional) from any heating circuit. It is also
possible to generate demand using a room
thermometer. The boiler can also switch on the
equipment via its heat requirement.
The control or local data of the boiler capacity can
be adjusted or changed.
The regulation prevents boiler temperatures falling
too low as this can affect the life expectancy of the
boiler.
Boiler temperatures that are too high are not
permitted for operational safety reasons.
Any elongation fissures on the insulation plates or
combustion chamber bricks do not affect their
functioning and therefore do not represent a claim
against the guarantee.
4.6
Safety devices
These must be dimensioned and installed to
conform to ÖN B8133.
The safety valve in the boiler circulation serves as
a safety last resort against malfunctions of the
equipment.
All legal safety regulations must be adhered to on-
site via the authorised specialist company. All
legal safety regulations must be adhered to on-
site via the authorised specialist company.
Earthing or potential equalisation must be carried
out on the machinery for the whole heating
system according to EN 60204-1 by an authorised
specialist company.
4.6.1
Safety temperature limiter STL
Should the boiler temperature exceed 95°C, the
equipment must be switched off for safety
reasons. The safety temperature limiter locks in
this event.
Possible causes may be:
Performance decrease in the boiler was
interrupted abruptly. This can occur due to
the switching off of a pump or sudden
shutting of the heating circuit mixer.
The load pumps are being controlled by the
HERZ
Control.
The
so-called
excess
temperature flue gas would be automatically
activated by the HERZ Control. This avoids
higher boiler temperatures.
The boiler is too large.
The fuel level is set too high.
Loss of power supply
Etc.
Firstly the cause of the failure must be found and
corrected and only then can the safety
temperature limiter be unlocked.
The boiler temperature must be under 75°C
before unlocking.
Only after this can the malfunction be rectified. To
do this the covering of the safety temperature
limiter must be unscrewed. Through gentle
pressure using a sharp object the safety
temperature limiter can be unlocked again. After
the cover unscrewed the rectification of the fault
must be carried out via the control box. The safety
temperature limiter is located right from the
operating terminal.
4.7
Start-up
The first start-up must be carried out by HERZ
factory customer service or an authorised
specialist (Otherwise the guarantee becomes
invalid).
Besides this the low pressure in the flue pipe
connecting piece of the boiler is measured after
firing with the designated solid fuels at least one
hour during running time and an advance flow
temperature of 70-85°C is achieved.
It can thereby be determined whether feed
pressure for the correct operation of the boiler
(formerly described as draw requirement“) has set
itself. If the existing chimney has not been
measured correctly or if the calculated chimney
values have not been met (inappropriate
connection, entry of secondary air, connection
piece too long, etc.) deviating values will result
and it will not be possible to operate the boiler
correctly.
During start-up and handover to the operator, the
functioning of all control and safety equipment
must also be monitored and the operation and
maintenance of the boiler and equipment must be
explained to the operator in detail.
The hydraulic balancing of the equipment (pipe
installation) must be carried out by an authorised
specialist company (installer). It is also the duty of
the installer (according to ÖNORM 12170) to
create documentation for the complete system
and this must be deposited in the boiler room.
