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
The boiler is designed for heating central heating water and
for use as a central heating boiler.
2.2 Operating the heating system
The heating system may only be operated and cleaned by
demonstrably trained persons (as per check-list). Children,
unauthorised persons or persons with a mental impairment
may only enter the boiler room under the supervision of an
authorised person. When unsupervised, the boiler room/fuel
store must be locked and the key kept in a place where it is
inaccessible to such persons.
2.3 Guarantee and liability

4 Safety systems PRO-04-00-00-00-01-BADE
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 10°C above specified temperature
The drive motor stops the fuel feed system and the flue
draught fan shuts down.
Safety level 2 Boiler temperature over 95°C
All heating pumps and the cylinder charging pump are
switched on to carry heat away from the boiler.
Safety level 3 Boiler temperature over 100°C
The STL (safety temperature limiter) trips and switches all
boiler control functions off while the 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 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.
Outer casing door open
The drive motors stop feeding the boiler with fuel
The flue draught fan switches to maximum extraction speed
If the outer casing door is closed again within 60 seconds,
combustion is continued
On the 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.

PRO Operating Instructions
13
On the fuel store outfeed unit Required in all countries
In addition, between the end of the fuel outfeed 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 outfeed 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.
Overfill prevention The overfill prevention function is triggered by the fill level
sensor in the fuel chute or the contact switch on the overfill
prevention cover. If the fill level sensor trips, the auger A1
stops and the auger G1 continues running. If the sensor
remains on for longer than 10min, the overfill fault is
generated. If the overfill prevention cover switch trips, the
auger A1 is stopped after 3 seconds and the overfill fault
registered immediately.
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. A
visual and audible warning device must be triggered when the
temperature exceeds 70°C.
Manually operated fire extinguishing facility
This fire extinguishing facility is for the purpose of combating a
fire seated in the fuel storeroom in the area of the outfeed 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 outfeed
equipment.
Note: The sprinkler system must be connected
on all systems regardless of local
regulations.
