2. PRODUCT DESCRIPTION
This model of boiler is equipped with an innovative and patented biomass burner that is capable of burning
not only wood pellets, but also biomass (maze, grape seed, etc...).
An automatic cleaning system, controlled by an electronic control box, always keeps the burner clean and
obtains great efficiency and reliable use. The modulating operation varies according to the boiler temperature
that has been set and results in optimal environment heating. During initial start up phase (approximately 10
min.) the burner automatically fills with fuel, while the resistors, heating up, ignite the flame. Once flame has
been detected by the combustion fume sensors, normal operation begins and, thanks to the microprocessor,
fuel intake can be changed, obtaining flame modulation. The electronic box controls continually check
temperature sensors, electric motors, and safety devices, in case of anomalies, it will stop functioning and
signal it on the display (see alarm code paragraph). Room heating is guaranteed by a circulator mounted inside
the boiler that will start once the temperature reaches 40°C. Below this temperature the boiler activates the
anti-condensing function, therefore stopping the circulator.
Production of domestic hot water is guaranteed by a motorised deflector valve, also fitted inside the boiler, and
managed by the boiler probe that signals the position and ensures the hot domestic water boiler has priority.
3. PELLET QUALITY
There are various types and qualities of pellets on the market and it is important that the ones you use are not
of abysmal quality. A poor, cheap quality pellet could contain glues, resins or chemical substances that could
seriously jeopardise the functioning and the safety of the product, by inciting blockage of ashes and smoke
discharger, forming corrosive gas, reducing machine performance, release polluting substances into the
atmosphere and window incrustation. Regulations on this matter have established that products using this type
of fuel must be fed with good quality pellets, compact and not very powdery. We recommend that you ask your
retailer for a suitable type of pellet, that are in compliance with DIN51731 standards or M7135 standards
including any updates.
The characteristics of wood pellet that should be used are: of a 6÷8 mm diameter, approx. 5÷20 mm length,
have an 8% humidity and a heating potential of 18200 KJ/Kg.
The manufacturer does not assume any responsibility for the use of poor quality pellets and therefore
the is non responsible if the boiler malfunctions as a result.
Store pellets at least 1 metre away from the boiler in a dry and sheltered part of the home.
SETTING THE FUEL
Before switching the appliance on, select on the display the kind of fuel you are going to use:
- Select “fuel 1” to use certified wood pellets (DIN PLUS / ö-Norm M7135) or good quality wood pellets having
a low humidity value (<13%) and a low ash residual.
- Select “fuel 2” to use non-certified wood pellets (for example made with bark and branches) having a high
humidity value (>13%) and a high ash residual.
- Select “fuel 3” to use a corn (humidity max 15%) mixed with wood pellets.
- Select “fuel 4 ” to use a biomass fuel: corn mixed with wood pellets, finely chopped (∅4mm minimum) or
whole olive pits, almond/hazelnut/pine nut husks ( ∅4mm minimum), pelletized vine pruning, cherry pits
(∅4mm minimum), miscanthus pellets, agripellets.
- List “fuel 5” remains available for the technician/dealer to set particular fuels that are not mentioned in the
above list.
In order to obtain a correct functioning and a high efficiency of the stove, it is necessary to select
the most suitable fuel list.
In order to obtain a correct functioning and a high efficiency of the stove, it is necessary to select
the most suitable fuel list. All chopped fuels (olive pits, husks, etc..) must have a minimum
diameter of 4mm.
