PELLET

- Quality standard
Only wood pellets certified by these standards or certifications should be used:
Standards:
• Ö-Norm M 7135 | Din 51731 | EN-14962-2 (all repealed and included in ISO-17225-2)
• ISO-17225-2
Quality certifications:
• DIN+
• ENplus: on the web site (www.pelletenplus.es) you can check all manufacturers and distributors with certificate.
It is strongly recommended that the pellet is certified with quality certifications because this is the only way to guarantee the constant quality of the
pellet.
Moreover, it must comply with the following requirements:
• Diameter: The pellet diameter should not be either lower than 6 mm or higher than 8 mm.
• 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.
• Additional requirements to combustible materials:
- Ash sintering point: The ash sintering point should be higher than 1100°C.
- Ash fusion point: The ash fusion point should be higher than 1200°C.
- Ash softening point: The ash softening point should be higher than 1150°C.
Transport and storage
-
However, the most important thing is to fulfil 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 "EN15234 pellets transportation and storage" . Please, only choose suppliers who transport and storage
pellets according to these rules.
Pellet supply
-
Open the tank cover on the top of the equipment and empty directly the pellet bag taking care of not overflowing. You should also avoid that the fuel
spills out and falls outside the hopper because it would fall into the equipment.
In case of HydroBoreal and HydroBoreal-A model boilers with a joined tank, to supply fuel to the tank, you must open the tank cover and empty the
pellet bag directly. If necessary, an additional ladder or platform will be required.
Remember that in order for the capacity sensor to activate the pellet loading motor of the joined tank automatically, the installer must have
electrically connected the tank engine to the boiler electronic board, as well as modify the parameters of the boiler to activate this option.
Otherwise, the fuel capacity sensor will warn you of the lack of fuel but it will not run the joined tank.
How to connect the annexed tank (optional only for HydroBoreal and HydroBoreal-A
-
models)
First of all, inside the annexed tank you will find two symmetrical and therefore different pieces, as shown in the
drawing, which serve to fix the auger to the tank.
hopper and having to make two new holes), the filling mouth to the corresponding height according to the model of our boiler (bottom in the case
of model of 27 kW and top in the model of 23 kW) to match the height of the tank. Once the filling mouth is positioned, we will have to cover the
resulting space left in the hopper, for which we cut through the cut line the unscrewed sheet of the hopper in the previous step, proceeding to screw the
piece into the two existing holes and having to make two new holes in the hopper again. In order to cut the part, you do not need any auxiliary tool,
only by repeatedly bending the part through the pre-cut line, due to the punching of the part, it will eventually get separated.
INSTALLATION, OPERATING AND SERVICING INSTRUCTIONS
You must choose the position of the auger in the annexed tank depending on
whether you want to place the tank to the left or right of the boiler, ie if the tank
is going to be placed to the right of the boiler, the auger should be positioned
towards the left of the tank and therefore you must use the correct part and
discard the one that does not serve.
Then, in order to connect the tank annexed to the boiler, we need to install the filling mouth, to do this, once the side
(right or left) where to place the tank is chosen, we must break the punching in the side chamber of the boiler, to later
access the side of the hopper where we will find a metal plate screwed to it with four self-tapping screws.
We proceed to unscrew this plate and, in its place, position/screw (taking advantage of two holes made in the
