2.4 Functional description
Low-emission and energy-efficient pellet boilers are characterized by the fact that the individual stages of
wood combustion: wood gasification - wood gas combustion - burnout take place separately from each other
in terms of space and time.
INFO
The numbering of the components refers to the boiler description drawings from the
previous chapter “Overview of components”.
Depending on the time programming, the pellets are transported from the annual pellet hopper to the pellet
storage hopper via the pellet feed connection. Feeding takes place via the dosing screw, the cell wheel, the
feed screw by means of an infinitely variable drive, onto the sliding grate.
After the pellets are ignited, the combustion air supply is regulated by a differential pressure sensor as the
combustion chamber temperature rises to ensure optimum degassing of the pellets and afterburning of
the wood gas in the combustion chamber and in the insulated flame chamber. The hot flue gas is then fed
through a single-pass high-performance heat exchanger, which enables particularly low flue gas tempera-
tures and thus ensures optimum utilization of the calorific value through flue gas condensation. The heating
water is heated particularly efficiently as a result. The fly ash is also separated here and transported into the
waste water via motor-driven turbulators and an additional water flushing device.
The remaining wood ash remains on the sliding grate and falls automatically into the ash box (6) due to the
linear movement of the grate
Combustion control
Combustion is controlled via the lambda probe and the differential pressure sensor. This allows the combus-
tion air quantity and combustion quality to be optimally regulated. The combustion air volume is adjusted dy-
namically depending on the required boiler output and the fuel. A speed-controlled fan is used to convey the
combustion air. Deviations in the fuel composition (calorific value, bulk density) can thus be almost complete-
ly compensated for in favor of low-emission and energy-efficient combustion.
2.5 Safety concept
Boiler control
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
14 Instructions for Use BPH 4/17 (2.29) © 2023 Brunner GmbH

- 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.
Safety devices
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.
Safety temperature limiter (STB)
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.
Blow-out pipe
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
Boiler safety group
The boiler safety group protects the boiler against overpressure. The boiler safety group consists of a safety
valve, a pressure gauge and an automatic air vent.
The safety valve is installed in the boiler safety group. A safety valve in accordance with EN ISO 4126 is in-
stalled at the factory as a safety device against overpressure. The safety valve must be installed in the im-
mediate vicinity of the boiler. The boiler safety group is part of the pellet boiler BPH 4/17.

Pressure expansion vessel
Closed heating systems must be equipped with a pressure expansion vessel. The volume of the pressure
expansion vessel must be dimensioned so that the pressure at the highest and lowest temperature in the
system is not impermissibly exceeded or fallen short of. Dimensioning should be carried out in accordance
with EN 12828 (“Heating systems in buildings”).
The pellet boiler BPH 4/17 is equipped with a pressure expansion vessel with a volume of 18 liters as stan-
dard. If a higher volume is required by calculation, the heating system must be equipped with an additional
pressure expansion vessel.
Prerequisite for proper functioning of the pressure expansion vessel:
- the pressure expansion vessel must be located near the heat generator and - with some exceptions - near
the lowest point of the heating system
- the pressure expansion vessel must always be connected to the return pipe
- the pressure expansion vessel and the associated connection pipe must not be thermally insulated.
2.6 Fuel and water quality requirements
2.6.1 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:
16 Instructions for Use BPH 4/17 (2.29) © 2023 Brunner GmbH

2.6.2 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.
