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 sta pays 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 sta, which must provide the buyer with a declaration of conformity for the system and
will assume full responsibility for nal 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 Standards present
in the country the appliance has been installed.
Extraame S.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 sta 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.

THE FUEL
12
Chapter3
THE FUEL
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: lignin.
As well as being an ecological fuel, as wood residues are made the most of, the pellet also has technical
advantages.
Pellet density is about 650 kg/m3and water content is equal to 8% of its weight. For this reason the pellet
does not have to be seasoned in order to obtain a suciently adequate heat yield.
The pellet used must comply with the features described by the Standard:
Ö-Norm M 7135
DIN plus 51731
UNI CEN/TS 14961
Extraame recommends the use of pellets with a diameter of 6mm with its products.
ATTENTION !
THE USE OF EXPIRED PELLETS OR ANY OTHER MATERIAL DAMAGES THE FUNCTIONS OF
YOUR PRODUCT AND CAN DETERMINE THE INVALIDITY OF THE WARRANTY AND THE
ANNEXED RESPONSIBILITY OF THE MANUFACTURER.
N.B. It is important to periodically check the residue pellet inside the tank to avoid it
nishing completely, which results in the boiler switching o.
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
responsibilityofthemanufacturer. Extraameinvites the user tousepelletincompliancewiththedescribed
features and the Standards in force.
gure 3.1
PELLET FEEDING
During rst product use, feed the
pellet inside the tank, as illustrated
in the gure, until completely full.

SAFETY DEVICES 13
Chapter4
SAFETY DEVICES
FLUE EXHAUST BREAKAGE
If the suction device stops, the electronic board immediately blocks the pellet supply.
PELLET FEED MOTOR STOP
If the motor reducer stops for any reason, the machine goes into alarm mode and the fumes motor
continues to function in order to expel all combustion gas until the minimum cooling level is reached.
DOOR MICRO SWITCH
(see gure 4.5)
When the product door is opened, a safety micro switch blocks fuel feeding.
NO IGNITION
If a ame is not developed during the ignition phase, the appliance will go into no ignition alarm mode.
TEMPORARY POWER CUT
If the power cut is less than 10 seconds, normal functioning will continue when the current returns. If the
power cut is longer than 10 seconds, the“black out” alarm will occur when the current returns, taking the
product to complete cooling. When cooling has ended it will re-start in automatic mode.
ELECTRIC SAFETY
The stove is protected against strong current changes by a master fuse that is found in the rear part of the
stove. (2.5A 250V Delayed).
FLUE EXHAUST SAFETY DEVICE
An electronic pressure switch blocks stove functioning and takes it to alarm conditions.
PELLET TANK TEMPERATURE SAFETY VIA 85°C BULB
(see gure 4.7)
If there is overheating inside the feed-box this device blocks pellet feed motor functioning; restoration is
manual and must be performed by an authorised technician.
The restoration of 85°C safety device is not under warranty unless the after-sales centre can show
the presence of a faulty component.

SAFETY DEVICES
14
Chapter4
WATER OVERHEATING SAFETY VIA 100° C BULB
(see gure 4.3)
When the temperature of the water inside the product is in proximity of 100°C, pellet feeding is blocked.
If the bulb trips, restoration of the safety device is manual and must be performed by an authorised
technician.
The restoration of 100°C safety device is not under warranty unless the after-sales centre can show
the presence of a faulty component.
MINIMUM AND MAXIMUM PRESSURE PRESSURE SWITCH
(see gure 4.6)
A minimum and maximum pressure pressure switch is installed in series with the pellet motor electric
power supply. If the pressure in the system is below 0.6 bar, the electric power supply is blocked to the
pellet feed motor. If the pressure in the system exceeds 2.5 bar, manual rearm of the pressure switch is
triggered: restoration of the safety device is manual and must be performed by an authorised technician.
Attention:anypresenceofairinthesystemcouldcausetheminimumormaximumpressurepressure
switch to intervene. If the minimum pressure pressure switch intervenes blocking pellet feed into the
machine, alarms may occur connected to the lack of fuel.
ATTENTION !
For regular functioning of the product an ideal system pressure of 1.1 bar is recommended (cold
system). Moreover, there must be no air in the system. Extraame recommends the installation
of suitable air vent devices in the system. Any air venting operations from the system or
the product is not covered by the warranty.
DEVICES NOT ON THE LIST
During installation of the stove it is MANDATORY to insert a manometer into the system in order to display
the water pressure.
INSTALLATION AND SAFETY DEVICES
The installation, relative plant connections, commissioning and inspection of correct functioning must
be carried out perfectly, in total compliance with Standards in force, both national and regional, as well as
these instructions.
For Italy, installation must be carried out by professionally authorised sta (Ministerial Decree dated
22.01.08 n°37).
Extraame S.p.A. declines all responsibility for damages to objects and/or persons caused by the
plant.
SAFETY DEVICES FOR CLOSED VESSEL PLANT
According to the UNI 10412-2 (2006) Standard in force in Italy, the closed plants must have:
Safety valve
Pump control thermostat
Acoustic alarm activation thermostat

DISTANCES OF SAFETY DEVICES ACCORDING TO THE STANDARD
Component Distance
Temperature safety sensors On the machine or not exceeding 30 cm
Devices missing because not standard (see table
on next page) Not exceeding one metre, on the ow pipe
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 thermo product ow pipe,
within a distance no greater than 1m from the machine.
The domestic heating appliances with automatic feeding must:
be equipped with a fuel block thermostat (gure 4.1, 4.3), or
be equipped with a cooling circuit prepared by the manufacturer of the appliance.
Thecoolingcircuit mustbeactivatedbyaheat safetyvalve suchto guaranteethat the limittemperature
set 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.
AUTOMATIC THERMOSTATIC MIXER VALVE MANDATORY
The automatic thermostatic mixing valve is applied in solid fuel boilers as it prevents cold water return in the
exchanger (gure 4.8).
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.
An elevated return temperature, allows eciency improvement, reduces formation of smoke condensation
and prolongs the boiler life span.
Valves on the market have dierent calibrations. Extraame 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 ow.
Extraame recommends not to use this device whenever the DHW is produced through an instant heat
exchanger.
