2.1 Safety Information
Non-permitted use!
Incorrect use of the boiler can cause severe injuries and damage!
The instructions and information provided in the instructions
should be observed!
Details on procedure for operation, maintenance and cleaning, as
well as troubleshooting for the boiler are included in the
individual instructions. Any further work should be carried out by
authorised heating engineers or by Fröling customer services.
External influences!
Negative external influences, such as insufficient combustion air or
non-standard fuel can cause serious faults in combustion (e.g.
spontaneous combustion of carbonisation gases or flash fires) which
can in turn cause serious accidents!
Instructions and information for versions and minimum values, as
well as norms and guidelines for heating components in the
instructions must be observed!
Severe injuries and damage can be caused by an inadequate flue gas
system!
Problems with the flue system, such as poor cleaning of the flue pipe
or insufficient chimney draught can cause serious faults in
combustion (such as spontaneous combustion of carbonisation gases
or flash fires)!
You can only be guaranteed of optimum performance from the boiler if the
flue gas system is running smoothly!

2.2 Permitted uses
The boiler should only be operated when it is in full working order.
It should be operated in accordance with the instructions, observing
safety precautions, and you should ensure you are aware of the
potential hazards. Ensure that any faults, which might impact safety are
traced and removed immediately.
The P2 Pellet Boiler is intended exclusively for heating up
heating water. Use only the fuels specified in 2.2.1 below.
The manufacturer or supplier is not liable for any damages
resulting from non-permitted uses.
2.2.1 Permitted fuel
Wood pellets from natural wood with a diameter of 6mm
Applicable standards:
Austria: ÖNORM M 7135 - HP 1 and/or DINplus certification
program
Germany: DIN 51731 - HP 5, DINplus certification program and/or
ÖNORM M 7135 - HP 1
Applies generally:
Before refilling the store, check for pellet dust and clean if necessary.
Non-permitted fuels!
Burning non-permitted fuels lead to a build-up of aggressive
sedimentation and condensation, which can lead to damage to the
boiler and also voids the warranty!
2.2.2 Who can operate the boiler
Only trained operators are permitted to operate the boiler.
No unauthorized access to the boiler room.
Danger: Personal injury and damage to property.
It is the responsibility of the operator to ensure that unauthorized persons,
especially children, are kept away from the boiler.

2.3 Design Information
It is generally forbidden to carry modifications to the boiler or to change
or deactivate safety equipment.
In addition to the operating instructions and the applicable regulations
for the country in which the boiler will be operated for installation and
operation of the boiler system, all fire, police, and electrical regulations
must be observed.
2.3.1 Official approval and obligation to report
Each heating system must be officially approved.
When installing or modifying a heating system, you must inform the
inspectors from the supervisory authority and get authorisation from the
building authorities.
Austria: Report to the construction authorities of the community or
magistrate
Germany: Report new installations to an approved chimney sweeper and to
the building authorities.
2.3.2 Requirements for heating water
The requirements for heating water are based on the following
standards:
Applicable standards:
Austria: ÖNORM H 5195-1
Germany: VDI 2035
If the system is topped up or refilled:
Prepare (soften) the water to prevent boiler scaling.
2.3.3 Ventilating the Boiler Room
The openings for the supply air and the exhaust air should be arranged
as nearly opposite each other as possible to achieve a good thermal
draught effect.
The supply air must be drawn in directly from outside. The exhaust
air must be discharged directly outside.
Provided they are not contradicted by the relevant building regulations
room where the boiler is to be installed, the following standards apply:
Applicable standards:
- TRVB H 118
- ÖNORM H 5170

Rule of thumb:
Provide a supply air cross-section of 2 cm
2
per kW of boiler rated output,
as per ÖNORM H 5170, but a total cross-section of at least 200 cm
2
2.3.4 Heating System Installation/ Standards
The following standards govern the installation of heating systems:
Applicable standards:
ÖNORM / DIN EN 12828 Heating Systems in Buildings
The following prior standards still apply:
Austria: - Closed systems as per ÖNORM B 8131
- open systems as per ÖNORM B 8130
Germany: - closed systems as per DIN 751 Part 2
- open systems as per DIN 751 Part 1
A storage tank with the proper dimensions will guarantee the best boiler
operating values during the entire heating period.
Return feed lift
If the heated water return feed is under the minimum return
temperature, a portion of the heated water outfeed will be mixed in.
Below dew point / condensation forms during operation without
return feed lift!
Condensation water and fuel residue combine to form an aggressive
condensate, leading to damage to the boiler!
Regulations demand the use of a return feed lift!

Safety
Design Information

2.3.5 Chimney connection / chimney system
The standard EN 303-5 specifies that the entire flue gas system must be
designed to prevent, wherever possible, damage caused by seepage,
insufficient feed pressure and condensation.
It should be noted here that flue gas temperatures of less than 160 K
above room temperature can occur within the permitted operating range
of the boiler.
The flue gas temperatures (when cleaned) and the additional flue gas
values can be found in the technical specification sheets.
Page 12, Boiler data for constructing the flue gas system
Install the connection to the chimney via the shortest path, as far as
possible under 30 – 5°. Insulate the connector.
The entire flue gas system (chimney and connection) must be worked
out as per ÖNORM / DIN EN 1338 -1 or prior standards ÖNORM M
7515 / DIN 705-1.
In addition, local and other legal regulations apply!
The chimney must be approved by a smoke trap sweeper or
chimney sweeper.
As per TRVB H 118 (only in Austria) an explosion flap must be
installed in the flue pipe or in the chimney.
Draught limiter
We recommend that you install a draught limiter 1
Install the draught limiter directly under the mouth of the flue line,
as there is always low pressure there.

2.4.1 Devices for preventing the boiler from overheating
Thermal discharge safety device
At around 100 °C a valve opens and sends cold water to the safety
heat-exchanger to decrease the temperature.
Safety Temperature Limiter STL
Stops combustion at a max. boiler temperature of 100 °C. The pumps
continue to run!
As soon as the temperature has gone back down, the STL (1) can
be mechanically unlocked.
Safety valve
Protection against over-heating/ excessive pressure:
When the boiler pressure reaches a maximum of 3 bar, the safety valve
opens and the heating water is released in the form of steam.
2.5 Safety information for installation room
1) Danger of fire due to flammable materials!
No flammable materials should be stored near the boiler.
2) Damage due to impurities in combustion air!
Do not use any hydrogen halides or any cleaning agents containing
chlorine in the room where the boiler is installed.
3) Keep the air suction opening of the boiler free of dust.
) The room where the boiler is installed must be frost-proof.
