SAFETY DEVICES

• SMOKE EXTRACTOR FAN BREAKDOWN
If the extractor fan stops, the electronic card automatically blocks the fuel supply.
• BREAKDOWN OF THE FUEL LOADING MOTOR
If the geared motor stops, the thermo-stove or insert keeps on working (only the smoke extractor) until the minimum working smoke
temperature goes down and stops.
• ELECTRICITY TEMPORARY FAILURE
After a short lack of electricity, the equipment will restart automatically. In the event of a lack of electricity the thermo-stove or insert hydro
may give off a small amount of smoke inside the room for a period of time of 3-5 minutes. THIS DOES NOT ENTAIL ANY HEALTH RISK. This
is a reason why Bronpi advises, whenever possible, to connect the primary air inlet pipe to the exterior of the house in order to assure that the
thermo-stove or insert does not give off smokes after a short power loss.
• ELECTRICAL PROTECTION
The thermo-stove or insert is protected against abrupt electricity oscillations through a general fuse placed in the back side.
(4A250V Retarded) (See drawing D2).
•
SMOKE OUTLET PROTECTION
The electronic pressure switch blocks the operation of the thermo-stove or insert in the event of an abrupt change of the
pressure inside the combustion chamber (door opening, breakdown of the smoke extraction motor, smoke returns etc). If this
happens, the machine will go into an alarm state (see drawing D3).
• PROTECTION IN THE EVENT OF HIGH TEMPERATURE OF PELLET (80ºC)
In the event of overheating of the internal part of the tank, this device stops the operation of the machine. The restart
needs to be done manually by an authorised technician (see drawing D4).
The replacement of the 80ºC safety device is not included in the warranty unless the technical assistance
centre can demonstrate a faulty component.

FLOW SENSOR (OASYS TECHNOLOGY).
Your thermo-stove or insert has a flow sensor (see drawing D6) placed inside the inlet of the primary air pipe that
detects the proper circulation of combustion air and the smoke exhaust. In case of insufficient air inlet (due to
incorrect smoke outlet or improper air intake), the sensor sends a "block" signal to the thermo-stove or insert.
The OASYS TECHNOLOGY (Optimum Air System) ensures a constant combustion by controlling automatically
the draught according to the characteristics of the flue (curves, length, diameter, etc) and the environmental
conditions (wind, humidity, atmospheric pressure, etc). To that end, the fitter must access the technical menu the
geographical altitude of the equipment installation place.

HYDRAULIC PRESSURE TRANSDUCER
If the pressure of the heating system is lower than 0.4 bars, the boiler will cease feeding fuel and
ultimately close down and stop.. If the pressure inside the heating system exceeds 2.5 bars, the display
will show the alarm "WATER PRESSURE FAILURE". To reset the safety device press button no. 4 (On/Off)
on the display for, at least, 3 or 4 seconds (see drawing D7).
Warning: the 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 activate.
In order to get a proper performance of the product, the ideal pressure of the installation should be set in, approximately, 1.0-1.4 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 of the heating circuit.
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 is likely to be inadequate in case of high water volumes.
INSTALLATION, OPERATING AND SERVICING INSTRUCTIONS
• WATER OVERHEATING PROTECTION (90ºC)
If the water temperature inside the circuit reaches near about 90ºC,
the fuel loading is blocked. If the temperature gauge is activated, the
restart needs to be done manually by an authorised technician (see
drawing D5).
The replacement of the 90ºC safety device is not included in the
warranty unless the technical assistance centre demonstrates a
faulty component.
