commencing with the installation, use and maintenance of the product, carefully read this guide. All local, national and European
regulations regarding the installation and use of the appliance must be met. The Manufacturer recommends carrying out all the
maintenance operations described in this manual.
This appliance must only be used as intended by the manufacturer. Any other use is considered incorrect and therefore hazardous;
consequently, the user shall be totally liable for the product if used improperly. Installation, maintenance and repairs must be carried
out by professionally qualified personnel, certified according to Decree no. 37 of 22 January 2008 and in compliance with current
regulations. In case of repairs only original spare parts supplied by the manufacturer must be used. Incorrect installation or poor
maintenance can injure or damage people, animals or things; in this case the manufacturer shall be relieved of all responsibility.
Before beginning any cleaning or maintenance operation switch off the appliance by means of the 0/I main switch and disconnect

3 –GENERAL DESCRIPTION
3.1 OPERATING TECHNOLOGY
Your appliance has been built to fully satisfy all your heating and practical requirements. Top-grade components and functions
managed with microprocessor technology guarantee high reliability and optimal performance.
3.2 THE PELLET
The appliance is fuelled by pellets, that is, cylinders of compressed sawdust; it his allows you to fully enjoy the heat of the flame
without having to manually stoke the combustion.
The pellets have a 6 mm diameter and a length between 10 e 20 mm. They have a max moisture content of 8%; a thermal value of
4000/4500 Kcal/kg and density of 630-640 kg/m³. It must be approved according to UNI EN 14961-2 A1 A2.
It is strictly forbidden to use any pellet type other than that specified above. The use of fuel that does not comply with the
above specifications not only immediately invalidates the warranty for the appliance but can also create dangerous
situations. Do not use the appliance as an incinerator, at the risk of voiding the warranty.
3.3 PELLET REFUELLING
The feedbox is situated in the top part of the appliance. The
load capacity specified in the technical data can vary
according to the specific weight of the pellets.
Take special care when loading the tank as the screw feeder
at its base is in motion. Take care when topping up with fuel
as the loading area can get very hot.
ATTENTION: It is normal to find some pellets remaining in the tank
even if the appliance shuts off because the pellets have run out.
Attention: when filling up the tank, take care not to drop any pellets into the internal parts of the appliance, as, in
extreme cases, this could generate live flames.
The manufacturer recommends emptying the tank and vacuuming the screw feeder zone once a month and during the
summer period.
Only pellets complying with the above specifications are to be loaded into the tank; in no case whatsoever must foreign
substances or objects be introduced into the tank, the brazier or any part of the generator.

4 –INSTALLATION
4.1 APPLIANCE LOCATION
Follow the general guidelines set out in paragraph 1.1 to the letter. Above all keep in mind that the flooring of the
room in which the stove is being installed must withstand the weight of the stove with the added weight of the pellet
load and the water contained in it.
ATTENTION: The room where the appliance is installed must be well-ventilated and
free from humidity and salty air. A high level of humidity or saltiness in the room can
lead to the onset of rust or corrosion which will not be covered by warranty.
If inflammable materials are located in the vicinity of the appliance (e.g.:
matchboarding, furniture, curtains, pictures and paintings, sofas) it is mandatory to
comply with the minimum distances illustrated (see figure at right)
Installation in the vicinity of heat-sensitive materials is only permitted if suitable
insulating and fireproof protection is placed between the object and the appliance
(ref. Uni 10683). If the flooring is made of wood or any other combustible material, it
is mandatory to install a fireproof floor protector plate between the appliance and the
floor. Installation in the vicinity of heat-sensitive materials is only permitted if suitable
insulating and fireproof protection is placed between the object and the appliance
(ref. Uni 10683). Failure to observe this instruction will immediately invalidate the
warranty.
The installer must issue a certificate of conformity for the installation which includes the design plans and the
following documents:
a) Report containing the type of materials utilised.
b) Project as defined in Article 5 of Ministerial Decree n° 37 22 January 2008.
d) References to existing partial or previous declarations of conformity (e.g. electrical wiring).
e) Copy of the certificate of recognition of the professional technical qualifications.
These documents must, by law, be kept together with the use and maintenance booklet. The customer is responsible
for verifying, directly or indirectly, that the installation has been carried out to perfection in accordance with relevant
regulations in force. Do not install the appliance in unsuitable rooms such as bedrooms, bathrooms, garages and/or
lock-ups. It is forbidden to place the appliance in environments with an explosive atmosphere.
ATTENTION, the appliance is not simply a household appliance: if the instructions set out in this booklet are not
followed and/or if installation of the appliance is not executed perfectly and/or the provisions in force are not strictly
complied with, dangerous conditions could arise for both objects and persons. It is the user’s responsibility to verify
the presence, in the room, of a vent necessary for supplying oxygen to the generator.
The installer must provide the final user with verbal instructions on the correct use of the appliance when the
appliance is set at work for the first time.
4.2 UNPACKING THE APPLIANCE
The appliance is supplied packaged on a pallet; before positioning and installing it dismantle the appliance from the pallet as
described.

The circulating pump installed in the appliance has the following features:
ATTENTION: flexible tubing with a minimum length of 70 centimetres must be used for all connections, as this
will facilitate moving the appliance for servicing.
ATTENTION: a connection must be made between the safety valve and the outlet to prevent damaging
materials surrounding the boiler when the valve is activated.
ATTENTION: To avoid continual startups and shut offs, the size of the plant must be such as to guarantee power
absorption that is not less than the power generated by the boiler running at reduced power.

APPARECCHIO
APPLIANCE
Over 61°C, the generator circulating pump is always active as the heat must be dispersed; consequently, the solenoid valve in the
zone with the greatest absorption must be opened for the following reasons:
• to prevent the generator from continually starting up and shutting off caused by the inevitable loss of heat to the header and/or
due to system tubing.
• to prevent the generator from raising the water temperature by just a few degrees each time it is switched off then back on until it
shuts down due to exceeding the maximum threshold temperature.
To adjust the ambient temperature in which the valve opened, we recommend connecting the room temperature thermostat to the
CHRONOTHERMOSTAT MODEM terminal that allows the machine to be shut off via an external contact and therefore also
restarted.
This ensures that the generator only activates if there is a real request for heat from the zone in which the chronothermostat is
installed.
Several parallel-connected room temperature thermostats can be installed in the CHRONOTHERMOSTAT MODEM. This will
ensure that the zone requesting heat automatically activates the generator.
In the event of frequent startups and shut offs due to the heat produced by the generator not being absorbed, the manual reset
safety thermostat trips and blocks the generator.
N.B. Use chronothermostats having at least 2°C hysterisis.
The system must always be capable of absorbing all the power that the generator is capable of delivering. If you do not observe this
requirement , the generator could be subjected to numerous stops and starts. It is recommended not to exceed three lighting cycles
per day.

ATTENTION: The water temperature in the boiler tubes in this case is not adjustable and depends on the system's delivery
temperature, that is the temperature set in the generator. The boiler tubes can be installed on the water return circuit. It is
recommended to install a water softener in the domestic water system in order to maintain the boiler at its peak efficiency.

APPARECCHIO
APPLIANCE
In order to guarantee correct absorption of the heat produced by the generator it is advisable to use a boiler tube with volume and
heat exchange capacity suitable for the power of the generator. The boiler tube must have a minimum capacity of 300l. In any case
the boiler tube must be capable of absorbing all the power that the generator is capable of delivering. If this rule is not observed, the
generator could raise the water temperature to such a point as to activate the safety limit thermostat which stops the fuel from
dropping into the burner and therefore forces the appliance to shut off.
The installer is required to install a valve that switches over to the system, powered by the appliance’s control unit, which trips when
the boiler tube is thermally “satisfied ”. Consequently, the system must be designed in such a way that the hot water produced by
the generator can reach the various rooms by acting on the zone valves.
ATTENTION: it is mandatory to earth the generator. If this instruction is not observed serious damage, which
is not covered by warranty, will result to the body of the appliance. Have a skilled electrician check the
earthing. There must be no electric potential (Volt) between the generator earth and the system’s real earth
(earth plate). To prevent electrochemical corrosion of the appliance body do not use galvanised pipes and
