WHAT IS THE PELLET? 11
Chapter 3
WHAT IS THE PELLET?
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/m3 and 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 6 mm with its products.
ATTENTION!

RESPONSIBILITY OF THE MANUFACTURER.
PELLET STORAGE
To guarantee combustion without problems, the pellets must be kept in a dry place.
PELLET FEEDING
To feed the pellet, open the tank lid located on the upper part of the stove, and empty the bag of pellets
being careful they do not fall out.

Chapter 4
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 stove 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
When the stove 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,
displaying “NO ACC”.
TEMPORARY POWER CUT
If the power cut is less than 10 seconds, normal stove functioning will continue when the current returns.
If the power cut is longer than 10 seconds, the stove“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
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 13
Chapter 4
WATER OVERHEATING SAFETY VIA 100° C BULB
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
A minimum and maximum pressure pressure switch is installed in series with the pellet motor electric
energy power supply. If the pressure in the system is below 0.6 bar, the electric energy 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:anypresenceof air inthe systemcouldcause the minimumormaximum pressurepressure
switch to also 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 the ideal system pressure must be calibrated at approx.
1.1 bar with cold system. Moreover, there must be no air in the system.
Extraame recommends suitable air vent circuit 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 adjust the system with a manometer 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
22.01.2008 n°37).
Extraame S.p.A. declines all responsibility for damages to objects and/or persons caused by the plant.
