INSTALLATION
GENERAL
The ue gas exhaust and hydraulic connections must be carried out by qualied personnel who must issue installation conformity
documentation compliant with national standards.
The installer must provide the owner or person acting for him, according to the legislation in force, with the declaration of conformity,
supplied with:
1) the use and maintenance manual of the appliance and of the system components (such as for example, the smoke ducts, chimney, etc.);
2) photocopy or photograph of the chimney plaque;
3) system booklet (where applicable).
The installer must ask to be issued with a receipt stating that the documentation has been provided, and must keep it with a copy of the technical
documentation relating to the installation.
For installation in a condominium, prior approval from the condominium's administrator must be requested.
Where required, check the exhaust gas emissions after installation. Should a sampling point be installed, it must be airtight.
COMPATIBILITY
Do not install in rooms with a re hazard. It is also forbidden to install it in living areas with the following characteristics:
1. where there are liquid fuel appliances with continuous or discontinuous operation that draw the combustion air into the room in which they
are installed.
2. wheretherearetype B gasappliancesintendedforheating,withorwithout domestichot water productionandin adjacent and communicating
rooms.
3. where the depression measured in situ between the external and internal environment is greater than 4 Pa.
N.B.: Watertight appliances can also be installed in the cases indicated in points 1, 2 and 3 of this paragraph.
INSTALLATIONS IN BATHROOMS, BEDROOMS AND STUDIO FLATS
Installation in bathrooms, bedrooms and studio ats is only allowed for sealed or closed hearth appliances with ducted combustion air taken
from the outside.
oor protection
POSITIONING AND SAFETY DISTANCES
The support surfaces and/or points must have a suitable capacity to bear the overall weight
of the appliance, accessories and coverings. If the oor is made of a combustible material,
we recommend using a non-combustible material to protect the front part from any burnt
material which might fall during routine cleaning operations. The generator must be level
to function properly. The side walls, the rear walls and the oor support surface should be
made of non-combustible material.
One must also bear in mind all laws and national,
regional, provincial and town council regulations in force
in the country in which the appliance has been installed,
as well as the instructions contained in this manual.
Air inlet
Under any condition, including in the presence of extractor hoods and/or of controlled forced ventilation systems, the pressure dierence
between the generator installation rooms and the outside must always be equal to or less than 4 Pa.
MINIMUM DISTANCES
Installation next to ammable or heat-sensitive materials is permitted only if the special
safety distances specied on the label at the beginning of the manual (pag.2) are
observed. If the materials are not ammable, you must keep a side and rear distance of at
least 100 mm (without the inserts). For products equipped with rear spacers, wall-mounting
installation is permitted exclusively for the rear side.
PREPARATIONS FOR MAINTENANCE
To carry out extraordinary maintenance operations on the product, it may be necessary to move it away from the adjacent walls. This must be
done by a technician authorised to disconnect the combustion product evacuation ducts and then reconnect them. For heaters connected to the
hydraulic system, the connection between the system itself and the product must be made in such a way that, when an authorised technician is
about to carry out extraordinary maintenance operations, it is possible to move the heater at least 1 metre away from the adjacent walls.

EXAMPLES OF CORRECT CONNECTION TO THE CHIMNEY
In the presence of type B gas appliances with intermittent operation not intended for heating, they must have their own aeration and/or
ventilation opening.
The air inlets must meet the following requirements:
they must be protected with grids, metal mesh, etc., but without reducing the net useful section;
they must be made so as to make the maintenance operations possible;
positioned so that they cannot be obstructed;
The clean and non-contaminated air ow can also be obtained from a room adjacent to that of installation (indirect aeration and
ventilation), as long as the ow takes place freely through permanent openings communicating with the outside.
The adjacent room cannot be used as a garage, or to store combustible material or for any other activity with a re hazard, bathroom,
bedroom or common room of the building.
FLUE GAS EXHAUST
The heat generator works in depression and is equipped with an outlet fan for ue gas extraction. There must be a single exhaust system for
the generator. Using a ue that is shared with other devices is not allowed.
The components of the ue gas exhaust system must be chosen in relation to the type of appliance to be installed in compliance with:
UNI/ TS 11278 in the event of metal chimneys, with particular attention to that stated in the specication;
UNI EN 13063-1 and UNI EN 13063-2, UNI EN 1457, UNI EN 1806 in the event of non-metallic chimneys.
The length of the horizontal section must be minimal and, in any case, no longer than 3 metres, with a minimum upward slope of 3%
There must not be more than 4 direction changes including the one due to the use of the "T" element.
A“T” tting with a condensation collection cap must be provided at the base of the vertical section.
If the exhaust is not inserted in an existing ue, a vertical section with a windproof end piece is required (UNI 10683).
The vertical duct can be inside or outside the building. If the smoke duct is inserted in an existing ue, it must be certied for solid fuel.
If the smoke duct is outside the building, it must always be insulated.
The smoke ducts must have at least one airtight inlet for ue gas sampling.
All the sections of the ue gas duct must be accessible to inspection.
Inspection openings must be provided for cleaning.
If the generator has a fume temperature lower than 160°C+ ambient temperature caused by the high yield (contact technicians) it
MUST be resistant to humidity.
A ue system that does not respect the previous points or, in general, that does not comply with the regulations, may cause condensation
phenomena inside it.
CHIMNEY CAP
The chimney caps must meet the following requirements:
they must have a useful outlet section no less than double that of the chimney/ducted system on which it is installed;
they must be adapted in order to prevent the penetration of rain and snow in the chimney/ducted system;
they must be built so that, in the event of winds coming from all directions and from any angle, the expulsion of combustion products
is in any case ensured;

CONNECTION TO THE MAINS ELECTRIC SUPPLY
The generator is supplied with an electric power cable to be plugged into a 230V 50 Hz socket, possibly with a circuit breaker switch. The
socket must be easily accessible.
The electrical system must be compliant with standards. The eciency of the earthing circuit must be checked. Unsuitable earthing of the
system can cause malfunctioning for which the manufacturer will not be held liable.
Power supply variations beyond 10% can cause faulty operation of the product.

11ENGLISH
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).
Extraame S.p.A. 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.
CHECK THAT THE PRELOAD OF THE EXPANSION VESSEL IS SET TO 1.5 BAR.
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.
Pay attention to the correct sizing of the system:
generator power compared to the thermal requirement
possible need for a buer tank

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 2.7 BAR.
If the pressure measured by the digital pressure switch is lower than 0.6 or higher than 2.7 bar, an alarm will be generated.
By taking the pressure of the water within standard values, the alarm can be reset by pressing the /1 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
circuit and having the machine perform the "air vent" function. (Following commissioning and with the machine cold, activate the "air vent"
function again. - see "SETTINGS" chapter)
BULB THERMOSTATS  RESET

(pellet hopper, door, ash drawer) must remain closed at all times.
They can be opened only for the time required to load the fuel
and for maintenance.
"CLOSE HOPPER  STOVE DOOR"
This indication means that you have 60" to close the hatch/
door and the pellet lid.
If not, during ignition the stove will go into "DEPR ALARM"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.).
STOVE POSITIONING
To ensure the stove works correctly, it should always be positioned so that it is perfectly level, using a spirit level.
RESETTING
The gure below shows the reset position (95°C). It is recommended
to contact the qualied technician if one of the resets should be
triggered, so as to verify the cause.
FUSE
If there is no power supply to the stove, check the state of the fuse
located in the box between the stove switch and the power cord
connection.

PELLETS AND FEEDING
Pellets are made by subjecting wood shavings i.e. the rejects of pure wood (without paint) sawmill, carpenter products and products from
other activities connected to working and transforming wood, to very high pressures.
This type of fuel is fully ecological as no glues are used to hold it together. Indeed, the compactness of the pellets over time is guaranteed by
a natural substance found in wood: lignite.
As well as being an ecological fuel, as wood residues are made the most of, the pellet also has technical advantages.
While wood has a caloric value of 4.4 kWh/kg. (with 15% humidity, thus after 18 months of seasoning), the caloric value of the pellet is 5
kWh/kg.
Pellet density is about 650 kg/m3and water content is equal to 8% of its weight. For this reason the pellets do not need to be seasoned in order
to obtain a suciently adequate heat yield.
THE USE OF POOR QUALITY PELLETS OR ANY OTHER MATERIAL DAMAGES THE FUNCTIONS OF THE GENERATOR
AND MAY INVALIDATE THE WARRANTY AND FREE THE MANUFACTURER FROM RESPONSIBILITY.
PELLET HOPPER  PRESSURISED CLOSURE.
During stove operation, the pellet hopper lid must always be closed.
Keep clean
Do not place the bag Directly on the stove to loaD the tank.
always use a scoop to loaD the tank. Do not rub or place weights on the tank seal. keep the tank cover
seal supporting surface clean at all times. check the conDitions of the seal frequently. if DamageD,
contact your local authoriseD technician.
The pellets used must comply with the characteristics described by the
following standards:
EN PLUS class A1, ISO 17225-2 class A1
and
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 always recommended using pellets with a diameter of 6
mm with its products.
PELLET STORAGE
In order to ensure problem-free combustion pellets must be stored in a
dry place.
Open the tank lid and load the pellets using a scoop.
