All electric components that make up the product must be replaced with original spare parts exclusively by an authorised after-
sales centre, thus guaranteeing correct functioning.
SAFETY
The generator must not be used by persons (including children) with reduced physical, sensory and mental capacities or
who are unskilled persons, unless they are supervised and trained regarding use of the appliance by a person responsible for
their safety.
Children must be checked to ensure that they do not play with the appliance.
Do not touch the generator when you are barefoot or when parts of the body are wet or damp.
The safety and adjustment devices must not be modied without the authorisation or indications of the manufacturer.
Do not pull, disconnect, twist electric cables leaving the stove, even if disconnected from the electric power supply mains.
It is advised to position the power supply cable so that it does not come into contact with hot parts of the appliance.
The power supply plug must be accessible after installation.
Do not close or reduce the dimensions of the airing vents in the place of installation. The airing vents are essential for
correct combustion.
Do not leave the packaging elements within reach of children or unassisted disabled persons.
The hearth door must always be closed during normal functioning of the product.
When the appliance is functioning and hot to the touch, especially all external surfaces, attention must be paid
Check for the presence of any obstructions before switching the appliance on following a prolonged period of inactivity.
The generator has been designed to function in any climatic condition (even critical). In particularly adverse conditions
(strong wind, freezing) safety systems may intervene that switch the generator o. If this occurs, contact the technical after-
sales service and always disable the safety systems.
In the event the ue catches re, use suitable systems for suocating the ames or request help from the re brigade.
This appliance must not be used to burn waste
Do not use any ammable liquids for ignition
During the lling phase do not put the bag of pellets to into contact with the product
The majolicas are top quality artisan products and as such can have micro-dots, crackles and chromatic imperfections.
These features highlight their valuable nature. Due to their dierent dilation coecient, they produce crackling, which
demonstrate their eective authenticity. To clean the majolicas, it is recommended to use a soft, dry cloth. If a detergent or
liquid is used, the latter could penetrate inside the crackles, highlighting them.
ROUTINE MAINTENANCE
Based on Decree 22 January 2008 n°37 art.2, routine maintenance means interventions aimed at reducing degradation due to
normal use, as well as dealing with accidental events entailing the need of rst interventions, which however do not modify
the structure of the system upon which one is intervening or its intended use according to the requirements laid down by the
technical standards in force and by the manufacturer's use and maintenance manual.

HYDRAULIC SYSTEM
Certain concepts referring to the Italian UNI 10412-2 (2009) Standard are described in this chapter.
As previously described, when installing, all national, regional, provincial and town council Standards in force provided by the
country in which the appliance has been installed must be complied with.
During installation of the stove 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 total compliance with Standards in force, both national, regional and municipal, as well as these instructions.
For Italy, installation must be carried out by professionally authorised sta (Ministerial Decree dated 22.01.08 n°37).
The manufacturer declines all responsibility for damages to objects and/or persons caused by the system.

The domestic heating appliances with automatic feeding must: be equipped with a fuel block thermostat or with a cooling
circuit set up by the appliance manufacturer.
The cooling circuit must be activated by a thermal safety valve, in order to ensure that the limit temperature set forth by the
Standard is not exceeded.
Connection between the power supply unit and the valve must be free from interceptions.
The pressure upstream from the cooling circuit must be at least 1.5 bar.
TYPE OF SYSTEM
There are two dierent types of system:
Open vessel plant and closed vessel plant.
The product has been designed and realised to work with closed vessel systems.
CLOSED VESSEL PLANT
System in which the water it contains is not in direct or indirect communication with the atmosphere. Generally, the closed
vessel system has one of the following expansion vessels:
Pre-loaded closed expansion vessel with membrane impermeable to the passage of gases.
Automatic closed expansion system with compressor and membrane impermeable to the passage of gases.
Automatic closed expansion system with transfer pump and membrane impermeable to the passage of gases.
Expansion system without diaphragm.
GENERALITY
The closed systems must have:
Safety valve
Pump control thermostat
Acoustic alarm activation thermostat
Temperature indicator
Pressure indicator
Acoustic alarm
Adjustment automatic circuit breaker switch
Automatic circuit breaker switch (block thermostat)
Circulation system
Expansion system
Safety dissipation system incorporated with the generator with thermal safety valve (self-activated), whenever the
appliance does not have a temperature self-adjustment system
SAFETY VALVES
The load capacity of the safety valve must allow the discharge of a quantity of vapour, not lower than: Q / 0.58 [kg/h] where: Q
is the useful outlet power to the generator water expressed in kilowatt. The diameter of the minimum net transversal section
of the valve inlet must not be lower than 15 mm. The valve load pressure, equal to the calibration pressure, increased by the
overpressure, cannot exceed the maximum exercise pressure of the heat generator. The designer must check that the maximum
pressure existing in every point of the system, does not exceed the maximum exercise pressure of its every component . The
safety valve must be connected to the upper part of the heat generator or outlet pipes, very close to the generator. The length
of the piping between the generator coupling and the safety valve must not exceed 1 m.The piping connecting the safety valve
to the heat generator must not be interrupted and must not have, in any point, a cross-section lower than than that of the safety
15

ENGLISH
valve inlet or than the sum of the inlet cross-sections, in the event of several valves serving a single pipe. The discharge piping
of the safety valve must be realised in order not to prevent the regular functioning of the valves and not to cause damages to
persons; the discharge must ow immediately near the safety valve and be accessible and visible.The diameter of the discharge
piping must not however be lower than that of the outlet connection of the safety valve. For diameter of outlet connection it is
intended the minimum internal diameter on the valve outlet upstream of the eventual internal threading.
CLOSED EXPANSION VESSEL
Warnings: check that the preload of the expansion vessel is set to 1.5 bar.
The vessel maximum exercise pressure must not be lower than the calibration pressure of the safety valve, increased by
overpressures, characteristic of the same valve, bearing in mind the eventual level dierence between vessel and valve and
the pressure generated by the functioning of the pump. The capacity of the expansion vessel/s is evaluated depending on the
total system capacity as results from the project. The closed expansion vessels must comply with the provisions concerning the
design, manufacturing, conformity assessment and use of pressure appliances. Intercepting objects or section decreases must
be inserted/practiced on the connection piping, which can be constituted by system portions. The insertion of a three-way
intercepting valve which allows connection between the vessel and the atmosphere for maintenance Operations, is allowed.
Such device must be protected against accidental manoeuvres. The connection pipe must be realised in order not to present
scales or deposits storage points. In case of more heat generators which feed the same plant or the same secondary circuit, each
heat generator must be connected directly to the expansion vessel or plant expansion vessels unit, altogether dimensioned
for the total volume of water contained in the same plant or the same independent circuit. Where it is necessary to separate
the individual heat generator from the expansion vessel or expansion vessels unit, a three-way tap must be applied on the
connection piping between the generator and the vessel, in order to ensure, in every position, the connection of the generator
with the expansion vessel or with the atmosphere.The expansion vessels, the connecting pipes, the bleed pipes and drain pipes
must be protected from freezing, where this phenomenon occurs. The solution used for this purpose is described in the design.
COMMISSIONING CHECKS
Before connecting the boiler:
a) wash all system piping in order to remove any residues which might compromise the correct functioning of certain system
components (pumps, valves, etc.).
b) check to verify that the ue has adequate draft, is not narrowed and that other appliances do not discharge into the ue.
This is to prevent unexpected power increases. Only after this control can the ue tting be mounted between the boiler and
the ue. A check of the connections with pre-existing ues is recommended.
AUTOMATIC THERMOSTATIC MIXER VALVE (MANDATORY)
It is required to create an adequate anti-condensation circuit that ensures a return temperature for the appliance of at least 55°
C. The anti-condensation valve, for example, is applied in solid fuel boilers as it prevents the return of cold water in the heat
exchanger.
Routes 1 and 3 are always open and, together with the pump
installed on the return, they guarantee water circulation
inside the biomass boiler exchanger.
A high return temperature allows eciency improvement,
reduces formation of smoke condensation and prolongs the
life span of the generator.
Valvesonthemarkethavedierentcalibrations.Themanufacturer
advises use of model 55°c with 1" hydraulic connections.
Once the valve calibration temperature is reached,
route 2 is opened and the boiler water goes to the system via
the ow.

INSERTO COMFORT IDRO INSTALLATION
The insert is supplied with a sliding metal base that allows it to be installed in a pre-existing ue.
The sliding base allows the easy extraction of the insert both for feeding pellets into the feed-box and for any maintenance or
cleaning at the end of the season. If there is no pre-existing ue, it can be built using the insert support pedestal (optional kit);
in fact, the latter attaches the insert to the oor.

AIR CIRCULATION PIPES
Create air recirculation inside the structure that covers the insert for correct operation. This prevents the appliance from over-
heating.
To guarantee this, just make one or more openings in the lower and upper parts of the covering.
The following measurements must be respected:
LOWER PART (COLD AIR INLET) WITH TOTAL MINIMUM SURFACE 550 CM².
UPPER PART (HOT AIR OUTLET) WITH TOTAL MINIMUM SURFACE 550 CM².
Reference A
Hot convection air 550 cm²: The heat accumulated inside the covering
must be vented to prevent excessive overheating of the insert.
THE FLUE OUTLET PIPE MUST ALWAYS MAINTAIN A MINIMUM DISTANCE OF 50 MM FROM INFLAMMABLE PARTS.
Reference B
Forced ventilation:
The tangential fan distributes the heat developed by
the insert into the environment.
Reference C
Room air inlet 550 cm²:
To allow air recirculation an air inlet point must be
envisioned, which is preferably positioned in the lower
part of the structure in order to encourage convection.
The air must be withdrawn from the machine's working
environment.
