MACHINE DESCRIPTION
The boiler was designed to produce hot water
using solid biomass as the fuel.
The boiler was designed and built according to
standard EN 303-5.
The boiler was designed for connection to heat-
ing systems.
We will now give a short description of the
boiler functioning principle.
The combustible stored in the tank reaches the
crucible via the auger.
Combustion starts here using a resistor and air
brought inside by the fan on the smoke outlet.
The combustion chamber is immersed in water
contained in the cavities.
The heat is exchanged by conduction and radi-
ated from the flame and by convection through
the path taken by the smoke towards the chim-
ney flue.
The water, once heated, will flow in the system
via the circulator.
The boiler is equipped with a:
• Circulator
• Expansion tank 10 l (include a possible expan-
sion tank on the circuit)
• Safety valve 3 bar;
• Gauge to check system pressure
• Automatic cleaning system for crucible and
smoke exchanger
• Ash collection drawer
• Electronic control unit with electronic panel
with buffer control

FUEL USED
The boiler can burn granular type fuel, such as
pellets, olive waste and hazelnut shells
(no corn).
The fuel used must be good quality with the fol-
lowing minimum requirements:
• Chips or granules without any chemical addi-
tives
• Dimensions Max. length 20 mm and diameter
4 mm < Ø < 6 mm
• Heat power 21.60 MJ/kg =
5160 kcal/kg = 6,00kWh/kg
at 16.74 MJ/kg = 3999 kcal/kg = 4.65kWh/kg
• Density from 1.12 kg/dm
• Humidity under 10%
• Ash from 0.19% to 4.0%
The use of poor quality fuel damages the boiler
functions and can cause the warranty to expire
and with that the manufacturer's liability.
Edilkamin designed, tested and programmed
its products to guarantee the best performance
using Cat. A1 pellets according to Standard EN
14961-2:
N.B.: To guarantee problem-free combustion,
the fuel must be kept in a dry place with no
damp and far from heat sources.
