2.4 Safety concept
The detailed safety concept of the boiler control system ensures continuous monitoring and control of all op-
erating states and all connected sensors, fans and drives.
The primary aim is to control the combustion process and to comply with the safety requirements, including
EN 303-5 (“Boilers - Part 5: Boilers for solid fuels, manually and automatically fired, nominal heat output up
to 500 kW”).
If required, the following functions are also controlled automatically:
- Heat removal (with boiler pump)
- Boiler cleaning (grate and heat exchanger cleaning)
- Filling the storage tank
- Control of the pellet feed to the combustion chamber
- Automatic ignition
- Flue gas fan control
- Potential-free contact for external fault evaluation.
Control, communication and monitoring functions are automatically activated by appropriate configuration
during installation/commissioning.
All operating states as well as the current operating parameters are shown on the touch display. If operating
faults occur, the error messages appear on the display and warning signals sound.
All information and error messages are automatically saved in the archive and can be retrieved from there for
error assessment.
Software can be updated at any time via the existing USB port.
NOTE
Necessary safety devices in accordance with EN 12828 (“Heating systems in build-
ings”), which are not part of the scope of delivery, must be provided by the customer.
All safety devices must be professionally installed and checked for proper function at
least once a year. Expansion vessels, expansion pipes, safety valves and blow-out
pipes must be protected against freezing, e.g. by being installed in a frost-proof boiler
room.
The safety temperature limiter (STB) is a component that interrupts the control operation of the boiler. This
protects the boiler itself, or the system connected to it, from damage. Accordingly, the STB only becomes ef-
fective if the actual temperature controller should fail.
The boiler can only continue to operate if the safety temperature limiter is switched back on manually. The
boiler safety group also protects the heating circuit.
The blow-out line consists of the lines between the safety valve and the boiler.
The following applies to the blow-out line:
Nominal diameter [DN] Max. Length [m] Max. Number of bends [pieces]
20 2 4
25 2 4

2.5 Fuel and water quality requirements
2.5.1 Pellets
Wood pellets are a modern, environmentally friendly and standardized wood fuel. They are mainly pressed
from the bark-free sawdust from sawn timber production. The strength of the wood pellets is ensured by the
lignin contained in the wood, supported by the small addition of natural binding agents such as starch.
Quality classes of the pellets
The BRUNNER BPH pellet heating system may only be operated with wood pellets
that comply with the DIN EN 14961-2/ A1 standard or the international DIN EN ISO
17225-2 standard and have a diameter of 6 mm.
Only purchase wood pellets from suppliers who can guarantee their high quality.
The following certificates stand for assured pellet quality (wood pellets for use in small fires):
ENplus-
certification
mark:
ENplus A1 quality certificate with
ID number of a certified
German pellet dealer:
2.5.2 Heating water
Heating water
In modern heating systems, the quality of the heating water has a significant influence on the functionality
and service life of the heating system due to the combination of different heat generators and components
such as high-efficiency pumps or modern sensor technology. For this reason, there are corresponding na-
tional specifications such as VDI 2035 in Germany, ÖNORM H 5195-1 in Austria and similar regulations.
BRUNNER therefore recommends filling and refilling the heating system with appropriately treated water.
Drinking water analyses for the respective supply area can be requested from the responsible water supply
companies.

3 Planning advice
3.1 Requirements for the installation site
The boiler may only be installed in a dry environment.
The permissible ambient temperatures are between +4°C and +30°C.
The floor must be level, sufficiently stable and non-flammable. Stability and stability must be ensured from
the start. If the ceiling load is not sufficient, suitable measures must be taken to distribute the load.
The installation room must have adequate local lighting.
The combustion air must be technically free of chemical substances containing fluorine, chlorine, sulphur,
etc.
During operation, the boiler unit is closed and there is no risk of injury due to imbalance of rotating parts.
The boiler must not be installed in rooms in which:
- the required combustion air supply is not guaranteed.
- highly flammable or explosive substances are stored, manufactured or processed.
- in the case of room air-dependent operation, room air systems such as extractor hoods or controlled
ventilation systems are installed. This is only permitted if the safe operation of the boiler is ensured, if
- the ventilation and air conditioning systems only circulate air within a room;
- the ventilation and air conditioning systems have safety devices that automatically and reliably
prevent negative pressure in the installation room;
- simultaneous operation of the fireplace and the ventilation and air conditioning systems is pre-
vented by safety devices;
- the total negative pressure does not exceed 4 Pa - the negative pressure is created by the
combustion air flow of the boiler and the volume flows of the ventilation systems in the installa-
tion room and in the rooms connected via the ventilation network.
Inform the responsible district chimney sweep about the installation of the boiler be-
fore planning the system.
Ask him for advice regarding the planned installation room, connection and suitability
of the chimney and an adequate supply of combustion air.
3.2 Minimum clearances
It is necessary to adhere to the minimum clearances when setting up the boiler in order to ensure accessibility for main-
tenance and service work on the boiler.
Exhaust systems must be easily accessible for the chimney sweep for measuring, checking and cleaning work. A suit-
able stand area should therefore be planned.

Distances to fuel stores
The Model Firing Ordinance (MFeuV) is decisive for the minimum distances between fireplaces and flue systems to
combustible components or fuel stores.
Distances to fuel stores conform §12 (3):
If fireplaces are set up in the rooms in accordance with Paragraph 2 No. 2 to 4, these must:
- be outside the required collecting areas for leaking fuel and
- have a distance of at least 1 m from containers for heating oil or diesel fuel.
A distance of 0.1 m is sufficient if it has been proven that the surface temperature of the fireplace does not exceed 40°
C.
