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

8ENGLISH
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

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 PELLET STOVES
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.

12 ENGLISH
PELLETS AND FEEDING
Pellets are made by applying high pressure to sawdust, or wood waste products (not containing paint) from sawmills, carpentry and other
activities related to processing and working with wood.
Given that it does not use any glue to hold it together this type of fuel is completely environmentally friendly. In fact the compactness of the
pellets over time is guaranteed by a natural substance found in the wood itself: wood coal. In addition to being an environmentally friendly
fuel in that it pushes wood residues to the limits pellets also have technical advantages.
While wood has a caloric value of 4.4kWh/kg. (with 15% humidity after around 18 months of seasoning) the caloric value of pellets is 5 kWh/
kg.
Pellet density is 650kg/m3 and the water content is equal to 8% of its weight. For this reason they do not require seasoning in order to arrive
at a suciently adequate degree of heat yield.
THE USE OF EXPIRED PELLETS OR ANY OTHER MATERIAL WILL AFFECT THE FUNCTIONALITY OF YOUR
GENERATOR AND MAY LEAD TO THE TERMINATION OF THE WARRANTY AND CESSATION OF ANY ACCOMPANYING
RESPONSIBILITY ON THE PART OF THE MANUFACTURER
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.
CHECKS AND PRECAUTIONS FOR FIRST IGNITION
IMPORTANT!
IN ORDER FOR THE GENERATOR TO WORK PROPERLY, THE HYDRAULIC SYSTEM’S PRESSURE MUST BE BETWEEN
0.6 AND 2.5 BAR.
If the pressure detected by the digital pressure switch is below 0.6 or above 2.5 bar, it triggers a boiler alarm.
Bringing the water pressure within the standard values, it is possible to reset the alarm by pressing the button /1 for 3 seconds
(The alarm can be reset only if the fumes motor has stopped and 15 minutes have elapsed from the display of the alarm)
THE PELLET LOADING MOTOR DOES NOT WORK:
Due to the lling of the system, it is normal that there is air inside the circuit.
During the 1st ignition cycle, water movement causes the displacement of air bubbles and their out-ow from the automatic vents out of the
system. This can cause the pressure to drop and activate the minimum pressure switch, which stops the motor that transports the pellets and,
therefore, the heat generator.
Vent out the system, if necessary even multiple times, to remove the air, and reload it if the pressure is too low.
It is not a malfunction, but a normal occurrence due to its lling. After lling, the plumber must always thoroughly vent the system, using the
special vents in the circuit and running the "air breather" function on the machine. (After the rst ignition and with a cold machine, re-activate
the function "air breather" - see chapter "OTHER FUNCTIONS”)
BULB THERMOSTATS  RESET:
Check by pressing the reset buttons (85 - 100°C) located on the back of the appliance, before contacting a technician (see section RESET).

OPERATION AND LOGIC
IGNITION
Once the points listed previously have been checked, press key 1 for three seconds to ignite the stove.
15 minutes are available for the ignition phase. After ignition and having reached the control temperature, the stove interrupts the ignition
phase and passes to STARTING.
STARTING
During the start-up phase, the stove stabilises combustion, increasing it progressively, to then start ventilation and pass on to WORK.
WORK
During the work phase, the stove reaches the set power; see following item.
SET POWER ADJUSTMENT
Set the operating power (from 1 to 5).
Power 1 = minimum level - Power 5 = maximum level.
SET H2O TEMPERATURE ADJUSTMENT
Set the boiler temperature between 65 - 80°C .
PUMP OPERATION
The pump activates water circulation when the temperature of the water inside the stove reaches 60°C. As the pump always functions above
60°, an always open heating area is recommended to make product functioning homogenous, preventing overheating blocks. Normally this
area is dened“Safety zone”.
BURN POT CLEANING
At pre-set intervals the stove performs burn pot cleaning, switching the machine o.
When the cleaning phase is nished, the stove will re-start automatically and continue its work going back to the power level selected.
MODULATION and HOFF
As the water temperature approaches the set point, the boiler starts to modulate automatically bringing itself to the minimum power.
If the temperature increases beyond the set point, it will automatically switch o indicating HOFF and will automatically go back on when
the temperature drops below the set point.
SWITCHOFF
Press key 1 for three seconds.
When the operation has been performed, the appliance automatically enters the switch-o phase, blocking the supply of pellets.
The ue gas exhaust motor will remain on until the stove temperature has dropped below the factory parameters.
REIGNITION
The stove can only be re-ignited automatically or manually when the cooling cycle conditions and the preset timer have been satised.
J
NO IGNITION
FIRST IGNITION COULD EVEN FAIL AS THE AUGER IS EMPTY AND IS NOT ALWAYS ABLE TO LOAD THE BURN POT
WITH THE REQUIRED AMOUNT OF PELLETS ON TIME TO REGULARLY START THE FLAME.
IF THE PROBLEM OCCURS AFTER ONLY A FEW MONTHS WORKING, CHECK THAT ROUTINE CLEANING STATED IN
THE STOVE BOOKLET, HAS BEEN CARRIED OUT CORRECTLY.
DO NOT USE ANY INFLAMMABLE LIQUIDS FOR IGNITION!
DO NOT ALLOW THE BAG OF PELLETS TO COME INTO CONTACT WITH THE BOILING HOT STOVE DURING THE FILLING PHASE!
IN THE EVENT OF CONTINUOUS NO IGNITION, CONTACT AN AUTHORISED TECHNICIAN.

The thermo-stove is equipped with a kit for the production of
domestic hot water consisting of a plate heat exchanger, a motorised
diverter valve and a ow switch.
Domestic water production = 11 l/ min (t 30°C)
In absence of a request for domestic water, the heat generator heats
the system water. In the event of a request for domestic water, the
power of the generator is all used to produce domestic hot water
(heat is not supplied to the heating system).
In order to ensure proper operation in the domestic mode, the
thermo-stove must be switched on, in steady state conditions and
in operation.
If the heat generator is in the HOFF, TOFF, STANDBY, FINAL
CLEANING and OFF conditions, it cannot supply heat for the
production of hot water.
In the HOFF, TOFF conditions, the stove is switched o because
it has satised all heat requests, in this case a request for domestic
water will make the stove switch on again but one must wait for
the time required for it to reach steady state conditions.
In the event of STANDBY, the stove is switched o because it has
satised the additional thermostat (STBY clamp), in this case a
request for domestic water will not make the stove switch on again
until the additional thermostat is in request conditions because
the contact has priority over any request. Even in this case one
must wait for the time required for steady state conditions.
Avoid sampling hot water with very limited ow rates. Flow rates
below 3 litres per minute can make the thermo-stove switch from
the OPERANT state to the HOFFstate with consequent appliance
shutdown.
It is recommended to always leave a heating zone open in order to
ensure the dissipation of any excess heat produced by the thermo-
stove.
In order to prevent burns, one must t a thermostatic mixing valve,
in order to limit the temperature of the domestic water sent to the
utilities.
One must provide a suitable water ltration and softening system
according to the specic hardness of the water in the place where
the heat exchanger is installed.
The excessive deposit of limescale, as well as reducing the eciency
of the plate heat exchange, can compromise its operation.
Replacement of the plate heat exchanger in the event of excessive
fouling it not covered by the warranty.
The kit for the production of domestic hot water (plate heat
exchanger, motorised diverter valve and ow switch) is controlled by
a board integrated in the stove (system expansion board kit), which
allows various hydraulic congurations up to a maximum of four
heating zones, a puer and an auxiliary boiler.

MODES
SUMMER - WINTER: the mode allows setting SUMMER or WINTER
operation.
In the SUMMER mode the room thermostats relating to the heating
system and the puer are always satised; the thermo-stove works to
satisfy the DHW.
In WINTER mode, all requests are considered (DHW, heating system
and puer).
DHW
DHW is controlled via the integrated instantaneous DHW exchanger
(PH11=ON) and always has priority over all other requests.
HEATING
The activation of the outputs relating to heating is aected by the
operating modes (Summer/Winter) and by the presence or absence
of the puer.
With the puer deactivated, the outputs are activated when there is a
request and the temperature of the water in the boiler is hot enough.
With the puer activated, the outputs are activated when there is a
request and the temperature of the puer is hot enough.
One can enable the 4th Heating Zone. By setting parameter PH13
on “1”.
To activate the puer contact the dealer.
(Default setting PH13=0 = disabled).
PUFFER
With the puer active (set PH12=ON) the thermo-stove operates to
satisfy the requests of the puer and DHW (always priority). Default
setting: PH12= OFF - disabled.
To activate the puer contact the dealer.

ADDITIONAL THERMOSTAT
N.B. : Installation must be performed by an authorised technician.
There is a possibility to thermostat a room adjacent to the room where the stove is positioned: just connect a thermostat following the procedure
described in the next step (it is recommended to position the optional mechanical thermostat at a height of 1.50 m from the oor) . Stove
functioning with the external thermostat connected in the TA clamp can be dierent on the basis of the activation or disabling of the STBY
function.
The TA clamp leaves the factory jumpered, therefore it is always with closed contact (on request).
ADDITIONAL THERMOSTAT FUNCTIONING WITH STBY ACTIVE
When the STBY function is activated, the LED ashes. When the contact or external thermostat is satised (open contact / temperature
reached), the stove will switch o. As soon as the contact or external thermostat switches to the "not satised" status (closed contact/
temperature to be reached) it will re-ignite.
N.B.: stove operation depends on the temperature of the water inside the stove and relative factory setting restrictions. If the stove
is in H OFF (water temperature reached), any additional contact or thermostat request will be ignored.
ADDITIONAL THERMOSTAT FUNCTIONING WITH STBY DEACTIVATED
When the STBY function is disabled, the LED is xed.
When the contact or external thermostat is satised (open contact / temperature reached), the stove will go to minimum. As soon as the
contact or external thermostat switches to the "not satised" status (closed contact / temperature to be reached) the stove will start to work
again at the pre-set power.
N.B.: stove operation depends on the temperature of the water inside the stove and relative factory setting restrictions. If the stove
is in H OFF (water temperature reached), any additional contact or thermostat request will be ignored.
ADDITIONAL THERMOSTAT INSTALLATION
Switch the appliance o using the master switch positioned on the rear of the stove.
Remove the plug from the socket.
Refer to the electrical layout to connect the two thermostat cables to the relative clamps positioned on the rear of the machine, one is
red and the other black (TA
clamp). Every model can have a dierent position of the relative clamps in the rear of the machine. The
image is given as an example.
