Safety notes
1.1
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.
Basic safety information
Due to its functionally limited electrical and
mechanical characteristics with regard to usage,
operation and maintenance, if the equipment is
not able to work according to its appropriate use
or improper interference occurs, it may cause
serious health and material damage. It is therefore
conditional that the planning and implementation
of all installations, transportation, operation and
maintenance will be carried out and supervised by
responsible, qualified persons.
When operating electrical systems, certain parts
of those systems will always carry a hazardous
electrical voltage or be exposed to a mechanical
load. Only appropriately qualified personnel may
carry out work on the system. They must be
thoroughly familiar with the content of this and all
other manuals. In order for this system to function
safely and without any problems, transportation,
storage, operation and maintenance must be
carried out properly and carefully. Instructions and
information on the systems must also be heeded.
1.2
Installation
General notes
In order to ensure that the system will function
properly, the relevant standards and the
manufacturer’s installation instructions are to be
heeded during the installation of the system!
Documents from the manufacturer relating to the
heating devices and components used are
available from HERZ on request.
1.3
Operation and maintenance
1.3.1
General notes
Don´t open the boiler doors until
“HEATING OFF” is displayed,
otherwise a risk of deflagration
(explosion) is given.
1
In
unfavourable
operating
conditions, the temperatures of
parts of the housing may exceed
80 °C.
If the door to the ash container is
opened during operation, the fuel
supply will be shut off and the
boiler will switch to the burnout
phase. Afterwards the boiler will
switch to the operating mode
“HEATING OFF”.

Operation
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 or flames, the
system is to be switched off
immediately by operating the
emergency stop button. Notify the
HERZ
Customer
Service
department immediately.
 If the boiler room door main switch is
operated or if a power failure occurs, the
system will be taken out of operation
immediately. The remaining quantity of
residual fuel will burn independently
without giving off any toxic gases, if the
chimney draught is sufficiently. Therefore
the chimney must be designed and
produced in accordance with DIN 4705 or
EN 13384. When the boiler is switched on
again, the system has to be checked in
order to make sure that it is fully functional
and a safe operation of the whole system
must be guaranteed!

Warning notes
 The generated system noise during
operation does not present any danger to
the operator´s health.
 If the residual flue gas oxygen content
drops below the required minimum of 5 %,
the fuel supply will be stopped
automatically and will not be activated
again until the residual oxygen content
has risen to more than 5 % (fault text:
MIN O2 [%] 5.0, see chapter 1.1.1)
1.3.3
recommended to be carried out regularly by
authorised personnel or by the HERZ Customer
Service department.
Spare parts must be obtained directly from the
manufacturer or a distribution partner. The
customer will not be exposed to any health risks
as a result of the noise generated by the machine.

Prevent the entering of debris such as stones
or metal particles into the system! Sand and
soil lead to higher level of ash and slagging
precipitation.

Bulk density (BD) in as-delivered condition
> 150 kg/m³
There may be a formation of slag according to the
fuel quality, which has to be removed by hand.
The property classes A1 and A2 represent fresh
wood and chemically untreated wood residues. A1
contains fuels with low ash content, which
indicates little or no bark and fuels with lower
water content, while class A2 has a slightly higher
ash content and/or water content. B1 extends
origin and source of class A and includes
additional materials, such as short rotation
plantation wood, wood from gardens and
plantations etc., as well as chemically untreated
industrial wood waste. Class B2 also includes
chemically treated industrial wood waste and used
wood.
In the case of non-compliance, any warranty
or guarantee will be rendered null and void.
The burning of unsuitable fuels could lead to
uncontrolled combustion. Operational faults
and consequential damage are likely to occur.
3.2
From a water content of about 25 % and a
calorific value < 3.5 kWh/kg a reduced output is
expected.
If a different fuel is named explicitly on the order
respectively the order confirmation, the system
can be operated with the mentioned fuel.
Note: The system is set to the agreed fuel at the
commissioning. This setting (ID-fan speed, fuel,
flow and backflow, cycle times, etc.) should not be
changed when using constant fuel quality.

Safety devices
SAFETY DEVICES
The safety devices must be dimensioned and installed according to ÖN B 8133.
The safety valve in the boiler circulation serves as a final safety device against malfunctions of the
equipment.
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 whole heating system according to EN 60204-1
by an authorised specialist company.
1 Safety temperature limiter
4 Burn-back safety unit
Should the boiler temperature exceed 95 °C, the
equipment must be switched off for safety
reasons. The safety temperature limiter (STL)
locks in this event.
The burn-back safety unit prevents a burn-back
into the fuel storage room. The unit separates the
burning chamber and the fuel storage room. The
burn-back safety unit is conducted like a fire flap
and opens only when fuel is fed to the boiler.
Possible causes may be:
 Performance decrease in the boiler was
interrupted abruptly. This can occur due to
the switching off 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.
At First the cause of the failure must be found and
be corrected, afterwards the safety temperature
limiter can be unlocked.
The boiler temperature must be lower than
75 °C before unlocking.
Only after the temperature fell below 75 °C the
malfunction can be rectified. To acknowledge the
malfunction unscrew the STL covering and put
gentle pressure, using a sharp object, to the STL.
2 and 3 automated extinguishing device
The Boiler features an automated extinguishing
device. The device consists of a thermal safety
valve, a thermostat valve (3) and a water tank (2).
If the feeding screw temperature gets exceeded,
the valve opens independently and flushes the
feeding pipe. This extinguishing device is used as
a safety device at burn back.
8
5 Safety valve
The safety valve automatically releases, when the
pressure or temperature exceeds preset limits.
The safety valve has to release at the maximum
allowable pressure (according to boiler plate).
6 Safety heat exchanger
The safety heat exchanger is a built in safety
device and has to be connected to a thermal
release valve and installed, according to applied
standards. The safety heat exchanger has to be
connected directly to a cold water pipe (pressure
≤ 3 bar)
7 Ash container and burning chamber safety
device
The ash containers are connected contact-free
(inductive sensor) to the boiler.
Fuel storage room temperature monitoring
The fuel storage room temperature monitoring is
placed directly above the transport screw. If the
storage room temperature exceeds its preset limit,
the boiler will switch to the operate condition
„HEATING OFF“ and displays a fault report.
Additionally a fault sensor output gets active.
Conduct alerting in accordance with national
standards.

MODE OF OPERATION
6.1
Feeding system
The fuel is fed from the fuel storage room by the
room discharge system to the burn back
protection device. Fuel passes the hopper first,
afterwards the back burn flap. The back burn flap
gets steered by a spring loaded servo motor. If the
servo motor operates current less, the back burn
flap will close independently. Next the fuel is fed
towards the burning chamber by the feeding
screw. The achieved fuel level is a crucial factor of
the boiler heat output and operating mode.
6.2
Feeding type
The operation of the firematic is based on a
pulse-no-pulse ratio, which controls the feeding
system. The feeding values are set up via the
menu “Fuel values” (only available in the service
area) and modulated by the combustion control
system.
6.3
Combustion air control
The supplied combustion air is differentiated
between primary and secondary air. The primary
air is initiated directly into the embers. The
secondary air gets used to actuate the developed
flame to a completely. The air supply is piped via
vents on the burner side (underneath side cover).
The ID-fan on the backside of the boiler generates
low pressure within the boiler. The secondaryand primary air get sucked out due low pressure.
The ID-fan speed is controlled according to the
boiler temperature and the lambda probe control.
6.4
Boiler operation
The boiler starts up automatically with its built-in
automatic ignition, when heat is required. The
heat requirement can be controlled by the weather
or by a remote sensor (optional), depending on
any heating circuit. A room thermometer can also
be used to generate an external requirement. The
boiler can also be started up by the requirement of
a hot water tank.
The boiler output can be controlled by set up
values and adjusted to local conditions.
The boiler control prevents too low boiler
temperatures to avoid effect on the durability of
the system. Too high boiler temperatures are not
permissible.
Expansion cracks at insulating plates, respectively
burning chamber stones, don´t affect their
capacities and don´t represent warranty claim.
6.5
6
Commissioning
The commissioning must be carried out by HERZ
factory customer service or an authorised
specialist.
A
pressure
measurement
is
conducted
additionally after boiler has been operated with
the actual fuel for > 1 hour and a flow temperature
of 70-85 °C.
The result of the pressure measurement
represents a characterisation of the draught
during normal operation and shows, if the required
draught has been reached. If a deviation occurs,
the existing chimney has not been dimensioned
correctly or dimensioning underlying installations
have not been carried out correctly (e.g.: faulty
connections, false air inflow, too long connection
pipe,...) and the boiler does not operate properly.
During initial operation and commissioning the
system controls and safety devices must be
checked and the handling of the boiler as well as
the system maintenance schedule must be
explained to the operator.
The hydraulic balancing of the equipment (pipe
installation) must be carried out by an authorised
specialist company (installer). The installer’s duty
according to ÖNORM 12170 is to create
documentation of the heating system. The
documentation has to be retained in the boiler
room.

Operating and impermissible
temperatures
Boiler temperature
The HERZ firematic boiler operates at a boiler
temperature between 65 to 90 °C. If the return
flow temperature is lower than 55 °C, flue gas will
condense on the inside of the boiler. So if the
boiler starts up, the operating temperature (from
65 to 90 °C) must be reached as quickly as
possible in order to avoid condensation. The back
flow temperature may also be lower than the
permissible value at correct boiler operating
temperature. This condition should be avoided by
a back flow temperature increase.
Note!
All guarantee or warranty claims are invalidated in
the event of damage by corrosion arising due to
impermissible operation temperatures.
13
7
Operating conditions
Back flow temperature
7
The back flow temperature must exceed 55 °C
(60 °C) as quickly as possible, depending on the
boiler type. Temperature level retention of the
back flow or the boiler temperature is achieved
using a so-called back flow bypass or back flow
temperature monitoring. In this case the flow is
admixed via a pump and a valve to the back flow.
Heating off
The boiler´s heat energy can only be used after
the back flow temperature has exceeded 60 °C.
Too high boiler temperatures
The HERZ firematic boiler can be operated with a
maximum boiler temperature up to 90 °C. If the
decrease of performance drops suddenly (mixers
shut-off, hot water tank load pump switches off)
the boiler´s saved heat energy can overheat the
boiler.
The firematic boiler has three different preinstalled safety devices to prohibit a further
temperature increase:

Overheat temperature (higher than 92 °C
boiler temperature)
At this temperature the connected consumer
pumps get switched on in order to conduct
overheat (consumer pump connection to the
HERZ controls is required). If the consumer
pumps aren´t connected to the HERZ
controls, a higher probability of overheating,
resulting in failure, is given.

Thermal release valve
The thermal release valve must be
connected to the built in safety heat
exchanger, according to applied standards.

Safety temperature limiter – STL
If the boiler temperature exceeds 95 °C, a
fault report gets indicated, the boiler gets
switched off and the safety temperature
limiter locks itself.
Flue gas temperature
The flue gas temperature depends on the boiler
operation conditions, the fuel, the ventilator setting
and the boiler type.
OPERATING
CONDITIONS
During this phase the boiler is switched off, i.e. the
burner is blocked.
Ready
The boiler- respectively the buffer temperature is
sufficiently high to provide the required heat load,
or the boiler temperature has reached the switch
off temperature.
Ignition preparation
During this phase the grate gets cleaned and the
lambda probe gets pre-heated.
Pre-aeration
During the pre-aeration phase the burning
chamber and the chimney get purged with fresh
air.
Cold start
If the boiler room temperature is lower than the
identified boiler room ignition temperature
(150 °C), the boiler performs a cold start and fuel
is fed to the burning chamber. At the same time
the fuel gets ignited by the ignition fan. An ignition
monitoring is conducted during this phase.
After successful ignition, the boiler switches to the
burning phase and the ignition fan stopping time
(1 minute) starts to cool down the ignition fan
heating element.
If ignition wasn´t possible prior the maximum
ignition period (3x set up time), the boiler will
switch off and the fault “IGNITION” (see fault 66)
will appear in the fault list.
Scorch phase
During the scorch phase the boiler control tries to
achieve an even fire bed. The length of the scorch
phase can be set in the fuel value settings (only
available in the service area). Pay attention to a
higher oxygen content at the combustion to
achieve an even fire bed faster.
Observe:
The chimney must be insensitive to moisture and
calculated and dimensioned according to
DIN 4705 or EN 13384. HERZ does not carry out
chimney calculations. The chimney calculation
must be calculated by authorised personnel. A
miscalculated or undimensioned chimney may
lead to a malfunction of the system.
14
Start up phase
During the start up phase the boiler operates at
nominal heat output. If the boiler set temperature
is reached, the boiler will switch to the regulation
phase.
Operating conditions
7
Regulation phase
Freezing protection
During the regulation phase the boiler is
modulated between nominal load and partial load.
If boiler oversupplies heat, i.e. if the boiler target
temperature + control hysteresis gets exceeded,
the boiler will switch to the operating condition
„ready”.
If the freezing protection operates, the back flow
bypass pump will switch on only if the boiler is in
operating mode “HEATING OFF” or “BURNER
STOP”. Otherwise (freezing protection disabled)
the boiler will start up and heat up to minimum
boiler temperature 65 °C.
Burn out phase
Lambda control
If the boiler will be switched off the remaining
quantity of residual fuel will burn independently.
Pay attention to the burn out phase time setup, if
chosen too short, fuel will not be burned
accordingly.
The amount of material and the rotation speed of
the ID-fan are controlled by the lambda control.
The control is able to detect marginal deviations of
the fuel quality and induces a combustion
improvement.
Burner cleaning
During the burner cleaning phase ash gets
removed off the grate. The boiler switches to the
burn out phase and remaining fuel gets burned
out. Afterwards the grate gets cleaned and the
boiler switches to normal operation. The burner
cleaning interval is calculated by the feeding
screw operating time. The cleaning interval is set
up with the parameter “cleaning interval” in the
service area.
Heat exchanger cleaning
The Heat exchanger gets cleaned automatically.
The cleaning interval and duration is set up in the
service area with the parameter “heat exchanger
cleaning interval“ respectively „heat exchanger
cleaning duration“.
Boiler output control
The boiler output gets modulated by the boiler set
temperature + control hysteresis (= regulation
end). If the regulation end is reached, the boiler
will switch to the burn out phase.
Flue gas temperature control
If the maximum flue gas temperature is exceeded,
the boiler output will be reduced. If the actual flue
gas temperature is lower than the maximum flue
gas temperature, the boiler will switch to normal
output control.

TEMPERATURE MANAGER
The heat demand of the individual modules (boiler, hot water tank, heating circuit, solar, etc.) is controlled by
the temperature manager. The below-mentioned scheme (see figure 8.1) explains the functionality of the
temperature manager. A module contains of an in- and output. Every module sends a required demand
temperature to the temperature manager. The sent required demand temperature is a sum of an internal
calculated temperature demand + set up increase. The heat supplier (= heat generator respectively
boiler/hot water tank), which receives the different module demand temperatures from the temperature
manager, must supply the required temperature demand to the different modules. The temperature manager
calculates the maximum demand temperature of all modules.
Example:
Heat supplier = boiler

Symbols explanation
In this section important symbols are explained.
The CHIMNEY SWEEPING FUNCTION provides a test mode for the chimney sweeper. The
boiler is operated steadily at nominal output and all consumer values are set to its maximum
during the chimney sweeper carries out its measurements. The measurements must be
carried out after “chimney sweeping mode” appears on the display and a developed
flame exists. If the maximum boiler temperature or the permissible chimney sweeping time
is exceeded, the chimney sweeping function will abort. The chimney sweeping time is
25 minutes by default, the remaining time counts after boiler status “chimney sweeping
mode” starts.
With the aggregate-test connected components can be tested individually. The symbol is
only visible, if:
 the code has been entered (see chapter 9.5, page 20) and
 the boiler is in the “heating off” operation mode (only at the boiler aggregate-test!)
If the Aggregate-Test is active, the symbol will turn green and the message “AGG-Test
ACTIVE” is shown on the display.
Information such as firmware-module, hardware-module, software version etc., of each
module (boiler, hot water tank, buffer, solar, heating circuit).
These symbols (navigation) can be used to navigate in each module (boiler, hot water tank,
buffer, solar, heating circuit, hydr. compensator, net pump, zone valve, ext. demand). An
alternative to the illustrated navigation method is the wiping to the right or left.

External requirement
The external requirement module provides an interface to an external foreign control loop (e.g. central
building control system). The requirement, which can be digital or analogue, is registered as a required
temperature (e.g. boiler must temperature by the boiler or buffer top temperature by the buffer) in the heat
supplier (e.g. boiler or buffer).

External requirement at digital input:
At a digital request the external set temperature gets transmitted as value to the heat supplier.
At an analogue request a calculated (= linearly interpolated) temperature gets transmitted to the heat
supplier (see figure 9.18). The graph in figure 9.18 gets regulated by the parameters „analogue must
temperature 4 mA“ and „analogue must temperature 20 mA“.
Puffer
External requirement at analogue input
figure 9.18: Analogue set temperature as a function of the applied current signal of the external
requirement
At the input of the external requirement module a current signal between 4 and 20 mA should be given,
because a current signal is compared to a voltage signal insensitive to electromagnetic disturbances and
voltage losses at the cables. With an internal resistor (500 Ohm) the current signal is converted into a
voltage signal.

MAINTENANCE SCHEDULE
(Some points have also been prescribed in accordance with TGPF H 118!)
For safety reasons, maintenance must only be carried out with the main
switch turned off. However first of all, the system must be switched off by
means of the On/Off button and you must wait for the burnout phase. If you
have to climb into the storage tank or bunker, always make sure that there
is a second person available to supervise you.
Potential carbon monoxide enrichment may put your life in danger.
