HYDRAULIC SYSTEM
Certain concepts referring to the Italian Standard UNI 10412-2 (2009) are described in this chapter.
As previously described, when installing, all national, regional, provincial and council Standards in force provided by the country in which the
appliance has been installed must be complied with.
During installation of the generator it is MANDATORY to adjust the system with a manometer in order to display the water pressure.

INSTALLATION AND SAFETY DEVICES
The installation, relative system connections, commissioning and inspection of correct functioning must be carried out perfectly, in full
compliance with Standards in force, national, regional and municipal, as well as these instructions. For Italy, installation must be carried out by
professionally qualied sta (Ministerial Decree dated 22.01.08 n°37).
The manufacturer declines all responsibility for damage to objects and/or persons caused by the system.
TYPE OF SYSTEM
There are 2 dierent types of system:
Open vessel system and closed vessel system.
The product has been designed and made to work with closed vessel systems.
Pay attention to the correct sizing of the system:
generator power compared to the thermal requirement
possible need for a buer tank
SAFETY DEVICES FOR CLOSED VESSEL SYSTEM
In accordance with the UNI 10412-2 (2009) regulation in force in Italy, all the closed systems must be tted with: safety valve, pump control
thermostat, temperature indicator, pressure indicator, automatic circuit breaker block switch (block thermostat), circulation system,
expansion system, and safety dissipation built-in to the generator with thermal safety valve (self-activated), if the appliance does not have a
temperature self-adjustment system.
J
CHECK THAT THE PRELOAD OF THE EXPANSION VESSEL IS SET TO 1.5 BAR.

12 ENGLISH
DISTANCES OF SAFETY DEVICES ACCORDING TO THE STANDARD
The temperature safety sensors must be in place on the machine at a distance no greater than 30 cm from the ow connection. Whenever the
generators lack a device, those missing can be installed on the generator ow pipe, within a distance no greater than 1 m from the machine.
COMMISSIONING CHECKS
Before connecting the boiler:
a) wash all system piping thoroughly in order to remove any residues which might compromise the correct functioning of certain system
components (pumps, valves, etc.).
b) The company recommends installing a magnetic lter in the generator return, to increase the operational life of the boiler, make it easier
to remove impurities and increase the overall eciency of the system.
It is also advisable to perform an inspection using appropriate instruments, to check for any stray currents that may cause corrosion.
c) check to verify that the ue has adequate draught, that it is not narrowed and that other appliances do not discharge into the ue. This is to
prevent unexpected power increases. The ue tting can be mounted between the boiler and the ue only after this inspection. An inspection
of the connections with pre-existing ues is recommended.
ANTICONDENSATION DEVICE MANDATORY
Make sure a suitable anti-condensate circuit has been realised, which guarantees an appliance return temperature of at least 55°C. The
automatic thermostatic valve, for instance, is used in solid fuel boilers as it prevents cold water from returning into the exchanger. A high
return temperature allows eciency improvement, reduces formation of smoke condensation and prolongs the generator’s life span. The
manufacturer recommends using the 55°C model with 1”hydraulic connections.
For the products with the *PWM pump control thermostat, installation is considered equivalent to the realisation of a suitable anti-condensate
circuit in the case where::
- the heat generator pump is the only one in the installation, or
- there is a plate heat exchanger between the heat generator and the installation, or
- there is a hydraulic compensator or an inertial storage tank (buer) between the heat generator and the installation

cHecks and measures for commissioning
caution!
for correct generator operation, tHe Hydraulic system pressure must be between 0,6 and 2,5 bar.
Whenever the pressure detected by the digital pressure switch is lower than 0,6 or over 2,5 bar, the boiler goes into alarm mode.
By taking the pressure of the water within standard values, the alarm can be reset by pressing the ON/OFF key for 3 seconds
(The alarm can be reset only if the fumes motor has stopped and 15 minutes have passed since the alarm was displayed)
tHe pellet load motor does not function:
It is normal that there is air inside the circuit due to lling the system.
On the 1st ignition cycle, the movement of the water causes the air bubbles to move and be bled by the system automatic venting. This can
cause the pressure to drop and the minimum pressure switch to intervene, which interrupts operation of the pellet conveying motor and
therefore operation of the heat generator.
The system must be bled several times to eliminate the air and loaded when the pressure is too low.
It is not an anomaly, but normal phenomenon, due to lling. Following lling, the system must always be bled using the relevant vents in the

note for correct operation
Pellet hopper lid
Fire door
stoVe positioning
To ensure the stove works correctly, it should always be positioned so that it is perfectly level, using a spirit level.
bulb tHermostat reactiVation
The gure below shows the rearm position. It is recommended
to contact the qualied technician if one of the rearms should be
triggered, so as to verify the cause.
fuse
If the stove is not powered, have the condition of the fuse checked
by a qualied technician.
The following indications must be respected for correct pellet
stove operation:
Both during the functioning and when the stove is not in use,
all the machine doors (pellet hopper, re door, ash drawer) must
always remain closed. The machine doors can only be opened
for the time required to load the pellet and for maintenance.
Failure to comply with the above during operation will cause the
display to show the following:
“CLOSE HOPPER  STOVE DOOR"
This indication means that you have 60" to close the hatch/door
and the pellet lid.
If not,during ignition thestovewill gointo"DEPRALARM"mode,
while during normal operation the stove will go into "COOLING
 WAITING TIME"mode and then re-start automatically when
the correct conditions are present (stove cold, etc.).

THE USE OF POOR QUALITY PELLETS OR ANY OTHER MATERIAL DAMAGES THE FUNCTIONS OF THE GENERATOR
AND MAY INVALIDATE THE WARRANTY AND RELIEVE THE MANUFACTURER OF ALL RESPONSIBILITY.
Keep clean
DO NOT PLACE THE BAG DIRECTLY ON THE STOVE WHEN LOADING THE HOPPER!
ALWAYS USE A SCOOP TO LOAD THE HOPPER. DO NOT RUB AGAINST OR PLACE WEIGHTS ON THE HOPPER SEAL,
KEEP THE HOPPER LID SEAL SUPPORTING SURFACE CLEAN AT ALL TIMES. CHECK THE CONDITIONS OF THE SEAL
FREQUENTLY. IN CASE OF DETERIORATION, CONTACT YOUR LOCAL AUTHORISED TECHNICIAN.
PELLET TANK  PRESSURE CLOSURE.
During the operation of the stove, the pellet tank cover must always remain closed.
PELLETS AND LOADING
Pellets are made by subjecting wood shavings i.e. the rejects of pure unpainted wood from sawmills, carpentry products and products from
other activities connected to wood working and transformation, to very high pressures.
This type of fuel is fully ecological as no glues are used for its compaction. In fact, pellet compactness is guaranteed over time by a natural
substance found in wood: lignin.
In addition to being an ecological fuel, making best use of wood residue, pellets also have a series of technical advantages.
While wood has a caloric value of 4.4 kWh/kg (with 15% moisture, therefore after approximately 18 months of curing), that of pellets is 5
kWh/kg.
Pellet density is about 650 kg/m3and water content is equal to 8% of its weight. For this reason pellets do not need to be cured to obtain a
sucient heat yield.
The pellets used must be class A1 certied according to standard
ISO 17225-2 (ENplus-A1, DIN Plus or NF 444 of the following
category: “High quality NF biocombustible wood pellets”).
UNI EN 303-5 with the following characteristics: water content
≤ 12%, ash content ≤ 0.5% and lower caloric value >17 MJ/kg (in
the case of boilers).
The Manufacturer recommends using pellets with a diameter of
6mm with its products.
PELLET STORAGE
To guarantee combustion without problems, the pellets must be
kept in a dry place.
Open the tank lid and load the pellets using a scoop.
