2 Important notes BS-01
Your boiler has been designed and produced in accordance
with the latest technical advances and all applicable safety
regulations. Nevertheless incorrect operation, the use of
unapproved fuels or the failure to carry out necessary
maintenance and repairs can result in personal injury or
damage to property. You will avoid dangerous situations by
only using the boiler for the purpose for which it was designed
and by operating, cleaning and maintaining it correctly. Only
start up the heating system when it is in perfectly safe working
order.
2.1 Intended use BS-01
The boiler is designed for heating central heating water and for
use as a central heating boiler.

prevent damage to your heating system.
Power switch
The power switch must remain switched on at
all times and may only be switched off when
the system is not in operation.
Mains plug
Risk of fatal injury from electric shock.
The mains power supply is brought to the
boiler via the plug marked Mains. That plug
and other components of the system remain
live even when the Power switch on the
control panel is switched off.
Repair work
Repair work may only be carried out by
authorised technicians.
Touching live electrical components can cause
fatal injury.
Even when the Power switch is "OFF" some
components of the system are still live.
Therefore, when carrying out repair work it is
imperative that the power supply to the
heating system is disconnected by means of
the "mains plug" or a circuit breaker.
Emergency: In the event of electric shock, disconnect the power supply
immediately. Administer first aid. →Call the duty doctor.
Fault rectification
If faults occur, the causes must first be eliminated
on the basis of the information message on the
display (F0...) before resuming operation by
means of the "Quit" button.

Do not store any flammable items in the close
vicinity of the boiler.
Follow the local regulations.
when heating
Attention Danger of deflagration!
When the boiler is running please don’t open
the boiler door or cleaning openings
Filling the storeroom
Combustible gases in storeroom!
When filling the fuel storeroom from a tanker
truck or using a pressure-filling system, it is
imperative that the boiler is shut down.
If this rule is ignored, flammable and
poisonous gases can be drawn into the
storeroom.
Entering the storeroom
Attention LIFE DANGER!
In all biogenic substances may occur during
storage in the formation of gases. You can
enter the storeroom after 2 hours lifting.
Storerooms with a high level might be measured
(the quality of air) from authorised stuff before you
enter he room.
Risk of injury!
Only enter the store room when the system
is switched off. Always shut off the power
supply before entering.
Affix a sign to the storeroom door.
Keep the storeroom doors locked.
Protection against freezing
Anti-freeze function.
The system can only perform its freezing
prevention function if sufficient fuel is
available and there are no faults.
Fire extinguisher
Provide a fire extinguisher.
There must be a fire extinguisher placed
immediately outside the boiler room door.

4 Safety systems PH-01
To prevent the boiler overheating, the controller reduces the
heat output in certain situations. If the boiler still threatens to
overheat, the controller responds according to a set of defined
safety levels.
Safety level 1 15°C above specified temperature
The drive motor stops the fuel feed system and the flue
draught fan shuts down.
Safety level 2 Boiler temperature above 90°C
All heating pumps and the cylinder charging pump are
switched on to carry heat away from the boiler.
Safety level 3 Boiler temperature above 100°C
The STL (safety temperature limiter) trips and switches all
boiler control functions off while the heating circulation pumps
continue to run. The system remains switched off even if the
boiler temperature drops back below 90 °C. The system must
not be started up again until any faults have been rectified and
the boiler has been checked.
Power failure The controller, the flue draught fan and all circulation pumps
switch off due to lack of electricity if there is a power cut. The
glowing fuel bed on the grate continues burn with the natural
draught of the flue. As this operating mode is not ideal, a larger
amount of ash collects on the grate as well. As soon as the
electricity supply is restored, the controller takes control of the
heating system again.
Opening ash box or firebox door •The drive motors stop feeding the boiler with fuel
•The flue draught fan switches to maximum extraction
speed
•After the ash box/firebox door is closed, normal
operation is resumed
On stoker duct The stoker duct and feeder box are designed to be completely
air-tight as far as the fire safety flap. That means that any burn-
back is extinguished by lack of air. The fire safety flap is tested
and approved as a burn-back prevention device. A positioner
motor opens and closes the flap. Fuel delivery does not start
until the flap is completely open. If the event of a fault or a
power failure, the flap closes automatically of its own accord.
When the boiler is in operation, the controller prevents burn-
back into the stoker auger by replenishing the fuel. In addition,
a sensor monitors the temperature in the vicinity of the stoker
auger. In that way, burning fuel is continually pushed back out
of the auger duct. This burn-back prevention system always
functions unless the electricity supply to the boiler system is
cut off.

13
On the fuel store outfeed unit Required in all countries
In addition, between the end of the fuel out feed unit and the
burn-back prevention device there is a sprinkler unit that is
used instead of the temperature monitor with fuel stores with
a capacity not exceeding 50 m³ and is triggered at 55°C.
When the sprinkler is triggered, the sloping out feed auger
enclosure – which also serves as a burn-back inhibiting device
– is completely flooded. The quantity of water required to do so
is at least 20 litres. If the temperature drops back below 55°C,
the flooding is stopped.
The sprinkler system must be connected on all
systems regardless of local regulations.
Overfill prevention The overfill prevention function is triggered by the switch on the
overfill cover. The fuel out feed unit then runs in reverse for 5
seconds and then for 5 seconds forwards. If the cover switch
trips again, the out feed unit immediately stops.
Fuel stores > 50 m³ Requirement in Austria
A temperature monitor connected to a warning device must be
installed in the fuel storeroom at the point where the fuel
conveyor exits the fuel store and enters the boiler room. The
warning device must be triggered when the temperature
exceeds 70°C.
Manually operated fire extinguishing facility (HLE)
This fire extinguishing facility is for the purpose of combating a
fire seated in the fuel storeroom/bunker/silo in the area of the
out feed unit and is manually actuated. It consists of conduit
piping with a minimum size of DN 20 and is to be fitted in the
fuel storeroom immediately above the fuel conveyor close to its
exit point through the wall or ceiling and positioned so as to
obtain the maximum possible fire extinguishing effect. The
conduit piping is to be connected directly to a pressurised
water supply and provided with a stop tap located in the boiler
room. That tap must be identified by a sign carrying the
inscription "Fuel storeroom fire extinguisher". The design of
the fire extinguishing facility must be such that it cannot be
damaged by the delivery of fuel into the fuel store or by the fuel
out feed equipment.
