Bronpi boilers have several safety systems that guarantee a safe and an appropriate operation and
protect both the boiler and the user. Some of them are described below. If in doubt, see sections 7.5 and
7.6.
2. Symbol Description
This symbol highlights those parts of the text that try to avoid mistakes when handling the boiler. The
omission of these instructions could cause material damages and harm your health in case of wrong
handling.
This symbol highlights those parts of the text that try to help with a better understanding of the boiler
regulation or the heating circuit.
3. Safety Recommendations
 Do not open the combustion chamber or the ash pan door during the working process.
 Do not allow making operations with the boiler to people who are not familiar with it or do not have training
related to the installation and to the Bronpi boilers.
 Prevent children from being alone in the heating room without any supervision!
 Keep animals away!
 If you notice visible damages (e.g. water leaks, thermal deformations, smoke or fire traces, mechanical
imperfections, etc.) you should neither continue with the service nor restart it. The faults need to be
repaired. In case of any doubt, please contact a specialized technician or the technical service.
 If the installation remains stopped during a long period of time you should guarantee an absolute antifreeze
protection in every part where the water is stored in.
 Bronpi boilers should not be submitted to any external mechanical load (e.g. tray, rise means, support, or
similar.) This remark also applies to its individual components (door, cover, etc.)
 During the working process you can only touch the door handles. The temperature could reach very high
values in some other parts (smoke pipe, ash pan door, etc.)
 Use fireproof gloves when restocking the combustible material.
 Bronpi boilers will exclusively be used under prescriptions given by the planning, installation, rules, laws,
and instructions related to the product. Either the manufacturer or distributor is not responsible for the
damages or the consequences attributable to an incorrect installation, application, or handling or to an
insufficient maintenance or cleaning.
 Regarding the legionnaire’s disease, current general technical rules must be respected.
3.1. Safety Devices

Ignition Failure
If it does not appear a flame during the ignition process, the equipment will show in the display the message
“IGNITION FAILURE.” If you try again to ignite the machine, the display will show the message “WAITING
COOLING.”
This function serves to remind that before carrying out the starting up it is necessary to check that the burner is
completely clear and clean.
 Smoke Pipe Breakdown
If the extractor stops, the electronic card automatically blocks the pellet or the olive stone supply.
 Fuel Load Motor Breakdown
If the geared motor stops, the boiler keeps on working (only the smoke extractor) until the minimum working
smoke temperature goes down and stops.
In the case that the geared motor spins continuously, the boiler will cut its electrical supply. In the event of this
happening, the boiler will go into an alarm state.
 Electricity Temporary Failure
After a short lack of electricity, the equipment restarts up automatically. In the event of a lack of electricity
the boiler could give off a reduced amount of smoke during a period of time of 3-5 minutes. THIS DOES NOT
ENTAIL ANY SAFETY RISK. This is why Bronpi advises, whenever possible, to connect the primary air inlet pipe
with the exterior of the house in order to assure that the boiler cannot give off smokes after the mentioned lack of
electricity.
 Electrical Protection
The boiler is protected against abrupt electricity oscillations through a general fuse placed in the back part of
the boiler. (4A250V Retarded) (Picture 1).
 Exhaust Stack Protection
An electronic pressure switch blocks the operation of the boiler in the event of an abrupt change in the
pressure inside the combustion chamber (door opening, smoke extraction motor breakdown…). In the event of this
happening, the boiler will go into an alarm state. (Picture 2).
 Protection for High Temperature Inside the Fuel Storage Tank (Hopper -80 ºC)

In the event of an overheating of the internal part of the tank, this device blocks the operation of the boiler.
The restart needs to be done manually, dismantling its black protection and pressing the white switch. This manual
restoration needs to be done by an authorised technician (Picture 3.)
The restoration of the 80 ºC safety device is not included in the warranty unless the support service
demonstrates a faulty component.
 Water Over Temperature Protection (90 ºC)
When the water temperature inside the boiler circuit is near about 100ºC, the fuel loading is blocked.If the
temperature gauge goes off, the restart needs to be done manually, dismantling its black protection and
pressing the white switch. This manual restoration needs to be done by an authorised technician.
The restoration of the 90 ºC safety device is not included in the warranty unless the support service
demonstrates a faulty component.
 Hydraulic Pressure Transducer
If the pressure inside the hydraulic installation is lower than 0.4 bars, the fuel loading motor electricity supply
gets blocked. If the pressure inside the installation exceeds 2.5 bars, the display will show the alarm “WATER
PRESSURE FAILURE”. The restoration of the safety device will be done by pressing button no. 4 (On/Off) during, at
least, 3 or 4 seconds (Picture 4.)
Warning: the occasional presence of air in the installation can provoke the intervention of
the pressure transducer. If the device intervenes blocking the fuel load in the machine, the alarms
related to the lack of fuel may activates.
In order to get a proper performance of the product, the ideal pressure of the installation should be tared in,
approximately, 1.0 bars when the installation is cold; furthermore, it is necessary the absolute absence of air. Bronpi
Calefacción advises to have an adequate air purged circuit inside the installation. The occasional operation
of air purging inside the installation or the product is not included in the warranty.

 Installation Safety Devices
It is COMPULSORY to have a pressure gauge to visualize the water pressure during the installation.
Warning!!!
The closed expansion tank of the installation should have a dimension between 4 and 6% of
the total volume of installation; this is why the standard closed expansion tank could be
inadequate in case of higher water volumes.

5. Fuels
In order to guarantee a proper combustion, it is necessary to fulfill all quality standards in all fuels.
The use of fuels in disagreement with the specifications mentioned below implies the cancellation of
the warranty and the responsibility bounded to the product.
If you use fuels according to the present specification, we guarantee an impeccable working and good
performance values of the installation. In the event of not knowing any distributor who meet these criteria, we would
kindly inform you about the distributors that you may be interested in.
5.1. Pellet
- Quality standard
Only wood pellet certified under the standards Ö-Norm M7135 or DINplus should be used.
Besides these rules, BRONPI CALEFACCIÓN, S.L. stipulates the following requirements for wood pellet:
o Diameter: The pellet diameter should not be either lower than 6 mm or higher than 8 mm.
o Minimum length: The weight proportion corresponding to those wood pellets with a length
lower than 10 mm should not exceed 20% of the total combustible mass.
o Additional requirements to fuels:
 Ashes sintering point: The ashes sintering point should be higher than 1100°C.
 Ashes fusion point: The ashes fusion point should be higher than 1200°C.
 Ashes softening point: The ashes softening point should be higher than 1150°C.
- Transport and storage
However, the really important thing is to fulfill the transportation rules, since it is possible to damage good quality
pellets just by handling them in the wrong way during the transportation or the pouring in the hopper. The pellets
transportation to the final customer, or to the intermediate distributor, and the subsequent distribution are ruled by the
“ÖNorm 7136 pellets transportation and storage.” Based on this rule, it is the symbol “DIN approved pellets
logistics specialised company”. Please, only choose suppliers who transport and storage pellets according to the
“ÖNorm 7136 Transport” or certified with the symbol “DIN approved pellets logistics specialised company.”

5.2. Olive stone
- Humidity: The level of humidity in the pit should be between 6 and 8%. If the fuel does not have the
appropriate humidity it could generate some oils during the combustion. This will make the chambers of
the stove get dirty and it generates corrosion.
- Dimensions: The grain size of the pit should be between 3 and 4 mm. The combustion burner has to
be the right one for the olive stone combustion. Normally, the olive stone generates a bigger waste of
ashes and non-burnt pieces than the pellet. This is why it is so important to clean the burner daily and
to do a deep cleaning of the stove every 6 months rather than once a year.
6. Start-up
Configuration of the electronic regulation is very important regarding energy saving. During the starting-up,
it is convenient to have the first configuration done by a specialised technician. At the same time, in order to
guarantee an optimal output, the boiler and its components have to be received in situ by an authorised
specialised technician.
Before connecting the boiler to the voltage, you need to check every point of the following list:
- Assembly instructions observation:
Has every assembly step been properly done according to the instructions?
- Ash pan control:
Check there are not foreign bodies inside both the chamber where the ash pan is placed and the interior.
Also, check the vermiculite parts placed on the door and inside have not moved during the shipment.
While the boiler is working, none of its parts or instruments should be inside the ash pan or the loading
compartment. Close the door and check that you can close it perfectly.

Ash pan chamber

- Combustion chamber control
Please check that there are no objects inside the combustion chamber and place inside the appropriate
burner for the chosen working mode of the boiler as it is shown in the following pictures. Note that the
incorrect placement of the burner may cause problems in the combustion.
- Burner
- Plug in
Once all these points have been checked, please connect the socket with a grounded socket base of
~230V/ 10A retarded.
It is important to take into account the following points:
o The system should have been run according to the rule VDE 0100.
o The connection with the electric power network should not be done through an
extension lead (fire risk!)
Combustion chamber door

o It is advisable to install an automatic switch.
o Compare the machine nameplate data with the data calculated from your power
network.

7.3.2 Menu 1. Choosing Fuel
It establishes the fuel that we are going to use, either pellet or olive pit. In the
event of using wood pellet we will select “TYPE 1” while if we are going to use
olive stone we will select the option “TYPE 2”. Due to the existence of several fuel
qualities, Bio-Bronpi boilers allow to choose a third type of fuel “TYPE 3”. With this option, we try to get
a good combustion although the fuel has lower quality. However, it is necessary to reach some
mínimum quality requirements. For this reason, in the case of using adulterated fuel, with high humidity,
low density, anomalous size or with presence of impurities… Bronpi Calefacción S.L. will not be
responsible for the damaged caused by this.

7.3.3 Menu 2. Summer/Winter Mode
This menu has two options: “SUMMER” and “WINTER.”
In the event of selecting the “winter” mode we need to take into account that the boiler will allow us to
use simultaneously the heating system together with the SHW (Sanitary Hot Water) heating system. We always need
to give priority to the SHW heating system and it needs to be directly installed to our Bronpi boiler. In the event of
having connected the boiler only with our heating circuit, the boiler will work, anyway, in the same way and it will only
regulate the performance with the values we want. It is advisable to use this working mode during the coldest
periods.
In the event of selecting the “summer” mode, a proper operation is only guaranteed when we have installed
an SHW heating system. This is due to the fact that during the summer season the boiler considers unnecessary the
use of heating systems, so it will be only work in the case of demanding hot sanitary water. When our installation
does not have the SHW heating system it is advisable to select the “winter” mode.

In the upper left margin it is shown, by default, the word “OFF”; however, by pressing buttons no.1
or no.2 we should be able to change it to “ON” mode in order to inform the boiler that we are trying to introduce some
of the three programmes: daily, weekly or weekend.
After this, we need to choose the programme that we want to introduce: daily, weekly or weekend. To do so,
from the previous screen, we need to press repeatedly buttons nº5 and nº6 until we reach the desired option.
7.3.5.2 Sub-menu 04.02. Daily Programme
Let’s consider, for example, that we want to set up the daily programme. In this case, we need to go
