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, who 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 normatives
present in the country the appliance has been installed.
ExtraameS.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.

Chapter 3
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/m and water content equal to 8% of its weight. For this reason it is not necessary
to age the pellet to obtain a suciently adequate heat yield (on the contrary, wood has 15% humidity after
about 18 months’ageing).
To guarantee combustion without problems, the pellets must be kept in a dry place. The diameter goes
from a minimum of 5mm to a maximum of 8mm. Extraame recommends using 6mm pellet.
PELLET FEEDING
During rst product use, feed the pellet inside the tank, as illustrated in the gure, until completely full.
Pellet tank
1. Open the tank lid
2. Empty pellet inside the
tank
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
responsibilityof the manufacturer. Extraameinvitestheuserto use pellet incompliancewith the described
features and the Standards in force.

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
* Extraame recommends using pellet with 6 mm diameter.
Using pellet with features dierent 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 ow 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 Dthe pellet is burnt too quickly, preventing the formation of a homogenous base inside the
burner. The boiler may not be able to develop the declared power.
Excess fuel Dthe 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 modication of this parameter will lead to a
proportional variation of all boiler feeding speeds.

C.HEAT. CONFIGURAT
The Extraame boilers have the possibility to manage dierent external devices through the circuit board.
One of these devices can be a gas boiler which is dened as an auxiliary boiler (AUX C.HEAT). 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-o given by the weekly programmer).
The boiler conguration allows to choose in which way to use the auxiliary boiler.
There are 3 possible settings:
BIOMASS C.HEAT
BIOMASS / AUX
AUX C.HEAT.
BIOMASS C.HEAT: Only the biomass boiler works with this conguration.
BIOMASS/AUX: With this conguration, 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-o of the latter depending on
the requests analysed by the various devices in the plant and connected to the circuit board (e.g. domestic

hot water storage, puer, 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 o the biomass boiler through key 1, the auxiliary boiler is also switched o.
AUX. C. HEAT.: With this conguration, the biomass boiler remains o but powered. In this way, the
biomass boiler circuit board can supply power to the auxiliary boiler and will decide ignition/switch-o of
the latter depending on the requests analysed by the various devices in the plant and connected to the
circuit board (e.g. domestic hot water storage, puer, etc.).
If the boiler is on and set at BIOMASS C.HEAT or BIOMASS/AUX, after having set AUX C.HEAT switch the
biomass boiler o using button 1 to start functioning of the auxiliary boiler.
The ignition of the auxiliary boiler is always delayed by about 20 minutes.
To switch the auxiliary boiler o, act directly on the master switch of the same or set the BIOMASS C.HEAT
or BIOMASS/AUX.

SWITCHON AND FUNCTIONING CYCLE
Before switching the boiler on the following points must be veried:
the combustion chamber must be free and clean.
The burners must be completely free and clean.
Check hermetic closure of the re doors.
Check that the power supply cable is connected correctly.
