WARNINGS AND SAFETY DEVICES
INTRODUCTION
The boilers produced by our establishment are built with attention to the individual components in a
way to protect both the user and the installer from any accidents. It is therefore recommended that after
any intervention on the product, that authorised staff pay particular attention to the electric connections,
especially the stripped parts of the wires. These must not escape from the terminal board in any situation,
thus preventing possible contact with the live parts of the wire.
The instruction manual is an integral part of the product: make sure that it always accompanies the
appliance, even if transferred to other owners or user or is transferred to another place. If it is damaged or
lost, request another copy from the area technician.
This boiler must be destined for the use for which it has been expressly realised. The manufacturer is
exempt from any liability, contractual and extracontractual, for injury/damage caused to persons/animals
and objects, due to installation, adjustment and maintenance errors and improper use.
INSTALLATION
Installation of the boiler and auxiliary equipment in relation to the heating system must comply with all
current Standards and Regulations and to those envisioned by the law. Installation must be carried out
by authorised staff, who must provide the buyer with a declaration of conformity for the system and will
assume full responsibility for final installation and as a consequence the correct functioning of the installed
product.
It is necessary to bear in mind all laws and national, regional, provincial and town council normatives
present in the country the appliance has been installed.
ExtraflameS.p.A. cannot be held responsible for the failure to comply with such precautions. Before
installation, wash the pipes of the system well in order to remove any residues that could compromise the
correct functioning of the appliance. During installation, inform the user regarding:
a. In case of water leaks, he must close the water supply and promptly warn the after-sales technical
service.
b. The system working pressure must be checked periodically. If the boiler is not used for a long period of
time, it is recommended that the after-sales technical service is contacted to carry out at least the following
operations:
- Position the master switch on position 0.
- Close the water taps of both the heat system and the domestic hot water system;
- Empty the heating system and the domestic hot water system if there is risk of freezing.
COMMISSIONING
After the packaging has been removed, check the integrity and completeness of the contents.
If this does not comply, contact the dealer where the appliance was purchased.
During commissioning of the product, check the correct functioning of all devices, both safety and control,
which make up the boiler. All electrical components that make up the boiler must be replaced with original
spare parts exclusively by an authorised after-sales centre, thus guaranteeing correct functioning.
Before leaving the system, the staff in charge of commissioning must check boiler functioning for at least
one complete work cycle. The boiler must be serviced at least once a year, programming it in advance with
the technical after-sales service.

Chapter 2
THE FUEL
THE PELLETS
Pellets are realised 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 absolutely ecological as no glues are used to hold it together. In fact, the compactness
of the pellets is guaranteed through time by a natural substance that is 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.
Pellet density is 650 kg/m3 and water content equal to 8% of its weight. For this reason it is not necessary
to season the pellet to obtain a sufficiently adequate heat yield (on the contrary, wood has 15% humidity
after about 18 months’ seasoning).
To guarantee combustion without problems, the pellet must be kept in a dry place. The diameter goes
from a minimum of 5mm to a maximum of 8mm. Extraflame recommends using 6mm pellet.
PELLET FEEDING
During first product use, feed the pellet inside the tank, as illustrated in the figure, until completely full.
Pellet tank
1. Open the tank lid
figure 2.2
2. Empty pellet inside the
tank
figure 2.1
figure 2.3
It is important to periodically check the residue pellet inside the tank to avoid it finishing
completely, which results in the boiler switching off.
WARNINGS
The use of expired pellets or any other unsuitable material can damage certain boiler components and
jeopardise its correct functioning: this can determine the invalidity of the warranty and the relative
responsibility of the manufacturer. Extraflame invites the user to use pellet in compliance with the described
features and the normatives in force.
THE FUEL
15
Chapter 2
PELLET FEED ADJUSTMENT
The pellet used must comply with the features described by the Standard:
™ Ö-Norm M 7135
™ DIN plus 51731
™ UNI CEN/TS 14961
* Extraflame recommends using pellet with 6 mm diameter.
Using pellet with features different to those listed above or for the features of the smokes evacuation plant,
it is possible that the boiler presents alterations respect to its optimal functioning.
If the problem occurs after only a few months working, check that routine cleaning stated
in the boiler booklet, has been carried out correctly.
The boiler is equipped with an adjustment system which intervenes directly on the pellet flow inside the
burner, optimising the combustion process. There can be 2 types of problems correlated to the amount of
fuel: lack of fuel or excess fuel.
Lack of fuel D the pellet is burnt too quickly, preventing the formation of an homogenous base inside the
burner. The boiler may not be able to develop the declared power.
Excess fuel D the pellet is not burnt completely, continuing to build up inside the burner. The boiler may
excessively overheat or create blocking problems.
The regulation to be performed is a percentage. Therefore a modification of this parameter will lead to a
proportional variation of all boiler feeding speeds.
Controls procedure:
™ Press key 3 (menu/ok) to access the menu.
™ Press key 3 (menu/ok) to access the “USER MENU”.
™ Select “PELLET ADJUST MENU” using buttons 4(-) and 5(+) and press key 3 (menu/ok) to confirm.
The value “00”will appear on the display: keys 4(-) and 5(+) can be used to adjust the percentage increase/
decrease desired by 5 points per time (the parameter can be varied with a maximum travel from –50 to
+50).
Increase/decrease the percentage value by 5 points and try the boiler with the new calibration for at least
2 hours.
™ If combustion improves but is not yet optimal, act as previously for a further 5 points. Repeat the
operation until the problem is solved.
™ If combustion worsens, act in reverse order in the adjustment.
When the adjustment has been made, press button 1(esc) to confirm and escape.

THE FUEL
Chapter 2
WOOD
The prescribed fuel is wood, dry, pieces with 80-150mm diameter, seasoned for at least 2 years, containing
12-20% humidity, with heat power of 15-17 MJ/kg and logs about 330m long.
The fuel must be fed in neatly in order to form a wood stack as uniform as possible, avoiding air spaces and
which allows natural sliding towards the brazier once fuel is consumed. During every feed, check for air
chambers between the logs intervening with the appropriate provided tool to eliminate them.
Maximum performance and boiler duration is achieved using wood seasoned for at least 2 years. The
interdependence between the contained water and the fuel heat power is indicated in the following table.
The wood useful energy volume significantly decreases compared to the quantity of water.

WARNINGS!!!
The use of expired fuel or any other material, damages the functions of your boiler
and can determine the invalidity of the warranty and the annexed responsibility of the
manufacturer.
FUNCTIONING REVERSE FLAME
Burning fuel with the traditional system defined “direct flame” whether it happens in a chimney, or
thermo kitchen or boiler, all the fed fuel will burn together as it is covered by the flame, from the bottom
upwards.
For this reason it will not be possible to make it last long as, if the combustive air is adjusted to a minimum,
a combustion with low oxygen is obtained, with emission of smokes containing a high quantity of carbon
monoxide (CO) with the consequent loss of performance for non-burning.
Whereas, by inserting an adequate quantity of air, the wood duration will depend on the pieces of the
same and the potential of the hearth used.
It will also be very difficult to obtain an adequate insertion of combustive air to obtain a good combustion
without using an excessive amount of air and, as known, it tends to lower the combustion performance
due to the so called losses for sensible heat in the smoke.
These last two are determined by the fact that all combustive air inserted in the hearth which does not
take part in the combustion, is however heated by the flame and escapes from the chimney taking a
certain quantity of heat with it, which will therefore be wasted.
With regard to the real combustion, this will happen with a flame developing at a temperature of about
750-800°C to which certain substances contained in wood such as fir resin, larch, pine etc. will not be able
to burn completely and will tend to form soot and tar, causing a progressive blocking of the flue.
In a “reverse flame” boiler, also called “total gasification” combustion happens with a completely different
systems, such to almost completely avoid the inconveniences described previously.
The combustive air, subdivided in primary and secondary, is inserted through a fan which, if immediately
THE FUEL
17
Chapter 2
connected upstream of the smoke exhaust pipe (VACUUM BOILER) it will place the feeding chamber in
depression, sucking in the smoke through a loophole which opens at the bottom of the same chamber.
Functioning is as follows: wood directly in contact with the coal will over-heat, immediately developing a
gas as phenomenon of pyrolysis, the primary air inserted by the fan through appropriate openings will filter
the wood pieces fed until the coal is reached, igniting these gasses and determining its partial combustion;
in this way, a flame mainly composed of carbon monoxide which is a fuelling gas, is obtained.
The flame, in passing through the slot which communicates the feeding chamber with the lower chamber,
is reached by the secondary air (again inserted by the fan) which completes the combustion.
During this phase, there is a notable increase in the flame temperature, which can exceed 1100°C, allowing
all the substances to burn which, in a traditional system
would remain partially non-burned; also, the necessary excess air will be very reduced (about 20-30%)
against more than 100% necessary in other systems, limiting to the maximum losses for sensible heat in
the smoke.
Whereas, in the upper chamber, there will be hardly any flame as this is forced by the fan to go through
the central slot, the pile of wood fed is not covered by the flame and does not catch fire as it would in a
traditional system.
The wood is only consumed when it leans on the coal left by the previous combustion, therefore (purely
theoretically) the pile could be indefinitely high as long as the boiler continuous to function connected to
a plant which absorbs all its power without interruptions.
In fact, this situation, is only manifested in very rare cases, therefore, the load capacity is limited to allow
only a few hours functioning.
By further increasing the autonomy, notable inconveniences would be caused as, at a certain point, once
the request for heat on behalf of the heating plant ceases, the boiler should stop to avoid boiling therefore
switching off the fan which introduces the combustive air; but even with the fan at a still, the wood left in
the boiler would tend to ignite at the top, developing a certain quantity of gasses which would remain unburned depositing inside the feeding compartment and on the surfaces run by the smoke, the less volatile
substances, forming tar scales which can, in certain cases, obstruct the same smoke passages.
The wood would be consumed anyhow, without its heat power being used, causing a drastic total
performance reduction of the boiler; also, the smoke humidity would mainly remain inside the same boiler,
condensing and causing, in the long run, its corrosion.
For this reason, the dimensioning must be carried out correctly to avoid long pause periods which, as we
have seen, would cause notable inconveniences.
For no reason should the boiler be OVERSIZED respect to the plant requirement.

BOILER CONFIGURATION
The Extraflame boilers have the possibility to manage different external devices through the circuit board.
One of these devices can be a gas boiler which is defined as auxiliary boiler (AUX BOILER). It is called
auxiliary as its functioning is managed by the circuit board of the biomass boiler or due to an exact choice
on behalf of the user or due to a block of various nature (fuel exhaustion, an alarm, a manual or automatic
switch-off given by the weekly programmer).
The boiler configuration allows to choose in which way to use the auxiliary boiler.
There are 3 possible settings:
™ BIOMASS BOILER
™ BIOMASS / AUX
™ AUX BOILER
BIOMASS BOILER: Only the biomass boiler works with this configuration.
BIOMASS/AUX: With this configuration, the biomass boiler always has priority with respect to the auxiliary
boiler. If for any reason (fuel exhaustion, any alarm except for HIGH WATER TEMP etc) the biomass boiler
blocks and cannot restart its normal functioning, the auxiliary boiler is activated. The biomass boiler circuit
board will supply power to the auxiliary boiler and will decide ignition/switch-off of the latter depending on
the analysed requests of the various devices on the plant and connected to the circuit board (ex. domestic
storage, puffer, etc...).
The ignition of the auxiliary boiler is always delayed by about 20 minutes.
Once the biomass boiler functioning is restores, the electronic board will again exclude the auxiliary boiler
functioning. By switching off the biomass boiler through key 1, the auxiliary boiler also switches off.
AUXILIARY BOILER: With this configuration, the biomass boiler remains off but powered. In this way, the
biomass boiler circuit board can supply power to the auxiliary boiler and will decide ignition/switch-off of
the latter depending on the analysed requests of the various devices on the plant and connected to the
circuit board (ex. domestic storage, puffer, etc...).
If the boiler is switched on and set on BIOMASS BOILER or BIOMASS/AUX, after having set AUX BOILER
the biomass boiler will enter the FINAL CLEANING phase.
The ignition of the auxiliary boiler is always delayed by about 20 minutes.
To switch the auxiliary boiler off, act directly on the master switch of the same or set the BIOMASS BOILER
or BIOMASS/AUX.

TIMES CONFIGURATION ECONOMY PUFFER
The “Economy puffer” function maintains the puffer at lower temperatures compared to the technician
puffer setting, respecting time periods decided by the final customer. The logical functioning is based on
the principle to use the pellet only to maintain the puffer at lower temperatures than usual.
In a few words, the customer will use wood during the normal use of the boiler, with the puffer at higher
temperatures (setting between 70°C and 78°C); whereas, during periods where he is unable to carry out
loading, the boiler will use the pellet to maintain the puffer at a minimum, (setting between 40°C and
60°C).
example:
time 18:00
time 12:00
time 07:00
time 07:30
wood loading
economy puffer time period start
economy puffer time period end
wood loading
puffer setting
set puffer between 70° and 78°
set puffer between 40° and 60°
set puffer between 70° and 78°
With this example, the boiler will work for a lower puffer temperature set from 12:00 to 07:00.
For times outside the time period, the boiler will consider the original puffer setting, decided by the
technician, independent of the type of fuel used.
The “Economy puffer” functioning can only be used if the boiler is in Wood/Pellet mode.
The puffer set and economy puffer set can only be set by the authorised technician.
The “Economy puffer” function cannot be used with the boiler set in wood mode.
Should the boiler recognise a fuel obtained from wood, it will automatically deactivate
the economy puffer set, considering the original puffer set.

PRODUCT FUNCTIONALITY
Extraflame S.p.A. has foreseen two functionings for the combined boiler, in relation to the type of fuel
selected: WOOD and WOOD/PELLET.
Before switching the boiler on the following points must be verified:
™ Check the fuel feed:
™ The combustion chamber and the ash drawers have to be free and clean.
™ The burners must be completely free and clean.
™ Check that the power supply cable is connected correctly.
™ The bipolar switch in the rear part must be positioned on 1.
WOOD FUNCTIONING CYCLE
In this configuration the boiler will be manually ignited with wood following the procedure described
below.
1. Prepare a quantity of wood made up of logs and twigs inside the wood feeding compartment equal
to about a fourth of its total capacity so as to form a uniform bed near the burner, avoiding empty spaces
between the various pieces.
2. With the aid of materials like fire starters and paper, cause a flame.
It is forbidden to use flammable liquids to ignite the boiler. Extraflame S.p.A. does not
assume any responsibility with regard to damages to objects and/or persons.
3. Hermetically close both doors.
From the moment the flame has been sparked off, the front door will have to remain
closed until the boiler has completely cooled down.
4. Press button 1(esc) for 3 seconds: the boiler will pass to “IGNITION” and there it will remain until it will
have recognised the presence of flame.
5. Once recognised the flame, the boiler will pass to “START WOOD”, phase which allows the boiler to
uniform fuelling.
6. Once this phase is completed, the boiler will pass to work phase: at this point, open the upper door
without removing the safety catch, wait about 30 seconds, then open completely. Complete feeding
the wood, paying particular attention to the layout, as uniform as possible, of the fuel, avoiding empty
spaces between the pieces.
The feeding operations must be carried out in a maximum time of about 10 minutes at
the end of which the boiler will display “CLOSE DOOR”. During this phase, an acoustic
signal indicates the opening of the door: first intermittently, then continuously. If feeding
requires more time, close the door and open it again.
During the work phase, the boiler will heat the water inside to satisfy the heat requirements deriving
from the plant.
NOTE: The boiler works varying on 5 different power levels which cannot be adjusted as the adjustment is
automatic in relation to the set temperature set.
During the work phase, the boiler works to reach the desired temperature, decreasing the functioning
power as it nears the set set; if the temperature exceeds the set set by at least 5°C (c.h. set + 5°C), the
boiler switches off displaying “HOFF WOOD! DONT OPEN THE DOORS” on the display and will wait for
re-ignition until the temperature has not decreased by at least 5°C below the set threshold (c.h. set 5°C).
26
PRODUCT FUNCTIONALITY
Chapter 4
In case of request on behalf of the domestic storage or the puffer, the boiler reaches a
temperature which can result higher respect to the set set by the user.
During the “HOFF WOOD” phase, the fuelling is choked, reducing the air intake. This causes un-burning
and dirtying of the heat exchanger . In order to guarantee good boiler functioning, it is useful to feed
quantities of wood depending on the heat requirements of the building, in order to limit as much as
possible the state of “HOFF WOOD”.
7. The switching off of the boiler will happen automatically at the end of fuelling displaying “WOOD
LOADING END” on the display”.
WOOD/PELLET FUNCTIONING CYCLE
During this mode, the following information will be displayed alternately:
™ FUEL SETTING
™ ACTIVE FUEL
™ FUNCTIONING STATE
Fuel setting D “WOOD/PELLET”
Active fuel D “ACTIVE WOOD” if working with wood, “ACTIVE PELLET” if working with pellet.
Functioning state D See description below relating to the active fuel.
PELLET CYCLE
1. Press button 1(esc) for 3 seconds: “START” will be displayed on the display. In this phase, the appliance
cleans the burner through a shaking of the grate which acts as bottom.
2. Following,
the
boiler
will
pass
to
“IGNITION”:
in
this
phase,
the
appliance feeds the pellet inside the burner to start the fuelling process.
NOTE: The first time the product is used, even if the tank is full of pellet, there is the possibility that in
the first ignition cycle the pellets are not fed. This is because the pellet feed worm screw is empty. If at
the end of the first cycle the boiler still has not developed a flame, it will start from the START phase.
If at the end of the second cycle the boiler still has not developed a flame, the following writing will
appear on the display “ALARM NO FLAME”. In this case press button 1(esc) for 3 seconds until “FINAL
CLEANING” appears on the display, remove and restore current from the rear master switch and repeat
steps 1 and 2.
3. If points 1 and 2 have been carried out correctly, the moment the boiler develops the flame, the boiler
will pass to “BURNING”, flame settling phase before starting work.
4. Completed the burning phase, the boiler will pass to “WORKING” phase, where the
boiler will heat the water inside to satisfy the heat requirements deriving from the plant.
NOTE: The boiler works varying on 5 different power levels which cannot be
adjusted as the adjustment is automatic in relation to the set temperature set.
During the work phase, the boiler works to reach the desired temperature, decreasing the functioning
power once nearing the set set; if the temperature exceeds the set set by at least 5°C (c.h. set + 5°C), the
boiler switches off displaying “H-OFF” (automatic switch-off ) and will wait for the re-ignition until the
temperature has decreased by at least 5°C below the set threshold (c.h. set - 5°C).
PRODUCT FUNCTIONALITY
27
Chapter 4
In case of request on behalf of the domestic storage or the puffer, the boiler reaches a
temperature which can result higher respect to the set set by the user.
5. The last phase is the switch-off, which can be realised through manual control, button 1(esc) for 3
seconds, or through the weekly programmer. The display displays “FINAL CLEANING” and the boiler
stops definitely. Once completely cooled off, it displays “OFF”..
SWITCHING PELLET D WOOD
If the boiler detects the ignition of wood, it switches from pellet to wood:
™ Function “START WOOD” is activated which blocks the pellet feeding and completely burns the pellet
residue in the burner.
™ After a pre-established time, the boiler passes to “WOOD” mode, with its normal functioning, described
in the previous paragraph.
SWITCHING WOOD D PELLET
If the boiler detects a decrease in temperature correlated at the end of the wood feed, “CHANGE TO
PELLET” will be displayed on the display. In this phase it is possible to proceed as follows:
™ Feed the wood to continue the normal wood functioning
™ Wait for a further cooling of the boiler and the automatic passing to pellet which will start from
“START”, previously described.
During wood functioning it is possible to exclude/restore an eventual pellet re-ignition by pressing button
1(esc). In case of exclusion, “PELLET EXCLUDED” will appear on the display, and in case of feed exhaustion,
the boiler will pass to “WOOD LOADING END”.

PUMPS ANTI-FREEZE CYCLE
This function avoids the plant water freezing when the boiler is switched off. When the temperature read
by some of the boiler probes falls below a determined temperature value the circuit board will activate all
of the outputs relative to the pumps/electro-thermal controls.
Pumps/electro-thermal controls will stop when the temperature rises.
PLANT ANTI-FREEZE CYCLE
If the boiler anti-freeze function is not sufficient to stop the lowering of the water, the system antifreeze function activates, which ignites the boiler. The boiler will remain switched on until a determined
temperature level has been reached.
SAFETY AREA 1
This function activates if the water temperature inside the boiler exceeds 87°C: even if there is no request
for heat, the electro-thermal pump/control relating to area 1 is enabled.
The stopping of the electro-thermal pump/controls will happen when the temperature decreases.
It is fundamental that the installer foresees the presence of an important heating area in the home (AREA
1) in which at least one radiator is never closed.
ANTIBACTER CYCLE
This function only activates with boiler on and allows to neutralise the bacteria of Legionnaire’s disease.
This bacteria in the water reacts differently in relation to the water temperature:
™ Below 20°C the Legionnaire’s disease can live but in quiescence condition (it does not multiple but it
does not die).
™ Between 20 and 50°C the Legionnaire’s disease multiplies, with particularly high speed between 35
and 46°C, therefore right in the temperature area of normal domestic hot water use.
™ Between 50 and 55°C the Legionnaire’s disease can live but in lethargy condition (it does not multiple
but it does not die).
™ Between 55 and 60°C the Legionnaire’s disease is eliminated in about 6 hours.
™ Between 60 and 66°C the Legionnaire’s disease is eliminated in about 35 minutes.
™ Above 66°C the Legionnaire’s disease is eliminated in about 3 minutes.
To remedy this problem, if when the boiler is switched on the temperature of the water inside the domestic
storage is lower than 65°C for a period longer than 48 hours, the domestic storage water is heated (70°C for
at least 5 minutes) even in the absence of heat request, to neutralise the bacteria.

SAFETY DEVICES
FLUE EXHAUST BREAKAGE
If the exhaust stops, the electronic board blocks the functioning and sends the boiler in alarm.
PELLET FEED MOTOR BREAKAGE
If the motor reducer stops, the boiler continues to function until the minimum cooling level is reached.
NO IGNITION
If a flame is not developed during the ignition phase, the appliance automatically attempts ignition
again.
If no flame develops also in this case, the appliance will signal ignition failure alarm on the display.
TEMPORARY POWER CUT
If the lack of current is lower than 10 seconds, the boiler ignores everything and starts its normal functioning
in the state it was in. If the time interval is higher than 10 seconds, the machine will display the “BLCK-OUT
COOLING” alarm (see display table).
ELECTRIC SAFETY
The boiler is protected against strong current changes by a master fuse that is found in the rear part of the
boiler. (12.5 A 250V Delayed).
PELLET TEMPERATURE SAFETY DEVICE
If there is overheating inside the tank, this device blocks the pellet feed motor; restoration is manual and
must be performed by an authorised technician who will check the cause of the overheating.
PELLET PIPE THERMAL SAFETY
If the thermal sensor of the pellet pipe detects an increase in the temperature in the same pipe, it activates
a pipe cleaning cycle.
MECHANICAL SAFETY WITH FIRE-CUT ROTARY VALVE
At the base of the feed tank there is a fire-cut rotary valve which prevents an eventual flame propagation
to the pellet tank.
DOOR OPENING SAFETY
The boiler doors must never be opened during functioning or when the boiler is still hot!! The opening of
the doors during functioning causes the boiler to block with the relative signal on the display.
SAFETY DEVICES
33
Chapter 7
WATER BOILING SAFETY DEVICE
In case there is scarce amount of water in the boiler
or insufficient heat absorption on behalf of the plant
due to circulation block, overheating until boiling
point of the same water may be caused. A manual
re-arm thermostat block the pellet feed motor. The
manual restoring of the thermostat is carried out by
pressing the buttons located at the rear of the boiler
and covered by spin on caps.
The intervention of the after-sales centre for boiler
over heating is not covered by warranty in case the
machine has not been connected to an adequate
storage, with volume of at least 1000 litres (see
“WARRANTY” chapter).

SAFETY DEVICES
Chapter 7
Temperature safety sensors must be in place on the machine at a distance no greater than 30 cm from the
flow connection of the generator.
Whenever the generators lack a device, those missing can be installed on the generator flow pipe, within
a distance no greater than 1 metre from the machine.
Domestic type heating appliances with manual or manual-automatic feed inserted in closed vessel
heating plants, must be equipped with an internal cooling circuit prepared by the appliance manufacturer,
activated by a thermal safety valve which does not require auxiliary energy and such to guarantee that the
limit temperature set by the Standard is not exceeded. The connection between the power supply unit and
the valve must be free from interceptions; interception is allowed if the valve is activated by a specific tool.
The pressure upstream from the cooling circuit must be at least 1.5 bar.
MOUNTING OF HEAT DISCHARGE VALVE (NOT SUPPLIED)
The solid fuel heat generators must be installed with safety devices determined by laws in force. For this
purpose, the boiler TC 30 is equipped with a safety exchanger.
The safety exchanger must be connected on one side to the water network (A) and the other to the drainage
network (C). The heat discharge valve (compulsorily supplied by the installer for closed vessel plant for
manual and automatic-manual feeding appliances), which bulb will be connected to attachment B, once
the safety temperature is reached enables the cold water to enter the copper coil contained in the boiler,
discharging the thermal excess through pipe C towards a conveniently installed discharge. The pressure
upstream from the cooling circuit must be at least 0.15 MPa (1.5 bar).

The automatic thermostatic mixing valve finds applications in solid fuel boilers as it prevents cold water
return in the 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 efficiency improvement, reduces formation of smoke condensation and
prolongs the boiler life span.
Valves on the market have different calibrations. Extraflame advises use of model 55°c with 1” hydraulic
connections. Once the valve calibration temperature is reached, route 2 is opened ad the boiler water goes
to the system via the flow.
Lack of installation of the device voids the heat exchanger warranty (see “WARRANTY”
chapter).
INSTALLATION AND SAFETY DEVICES
Installation, respective plant connections, commissioning and correct functioning check, must be carried
out buy professionally authorised staff (M.D. 22 January 2008 nr. 37), in compliance with the regulations in
force, both national and regional, as well as with these instructions.
Extraflame S.p.A. declines all responsibility for damages to objects and/or persons caused
by the plant.

Chapter 8
BOILER CLEANING
Before carrying out any maintenance operation, the boiler must be in “OFF” state and completely cold. At
this point, remove power supply to the boiler by directly acting on the rear switch.
Never discharge the water from the plant, even partially, in order to avoid malfunctioning. Periodically
check the good functioning and integrity of the pipe and/or smoke exhaust device.
In case of work or maintenance of structures located near smoke pipes and/or smoke exhaust devices and
their accessories, switch off the appliance and, once completed work, have the efficiency checked out by
professionally qualified staff.
Do not clean the boiler and/or its parts with easily flammable substances (ex. petrol, alcohol, etc…).
Do not leave containers of flammable substances in the room where the boiler has been installed.
Do not clean the thermal control unit whilst the boiler is working.
At the end of every heating period, it is necessary for the boiler to be inspected by professionally qualified
staff in order to maintain the plant perfectly efficient.
An accurate maintenance is reason for savings and safety, in fact the presence of soot and scales on the
exchange walls, reduce boiler efficiency and do not allow to maintain the declared performances. If the
power supply cable is damaged, it must be replaced by authorised after-sales assistance.
DAILY CLEANING
The use of the lever located on the left side of the boiler, guarantees good functioning of the same avoiding
the forming of layers of ash which opposes to the normal turning of smoke.
For this reason Extraflame recommends to repeat the movement indicated in the figures below at least 4/5
times a day.
