Electrical connection
The electrical installation and connection
work must only be carried out by an
authorised electrical specialist.
All applicable rules and regulations must
be observed.
The electrical installation should include a
type A circuit breaker.
The applicable guidelines and
directives must be observed, as well as
the electrical circuit diagram supplied
with the burner!
• Make sure that the appliance is
connected to an efficient earthing system.
• Make sure that the earth wire is a couple
of cm longer than the other wires in the
power supply cable.
• Check to ensure that the power supply
voltage is as specified in the electric
diagram and in data plate.
• Burner fuse: 5 A.
Electrical connection (plug-in)
It must be possible to disconnect the
burner from the mains using an
omnipolar shutdown device complying
with the standards in force.
The burner and heat generator (boiler) are
connected to the terminal block of the
cabinet (fig.1).
Connecting the gas train
Connect the gas train to the plugs on the
burner.
The burners are produced with
connections suitable for power supply
380-400 V three-phase.
The burners with electric motors of an
output lower or equal to 3 kW can be
adapted to 220-230 V (please follow the
instructions on the backside); motors with
higher output can only work 380-400 V
three-phase. In case of request of burners
different from the above mentioned
standard, it is recommended to make
specific mention in the order.
Instructions: how to adapt electric
motors of an output lower or equal to 3
kW to 220-230 V power supply
It is possible to change the voltage of the
burner by operating as follows:
1. change the connection inside the

electric box of the motor, from star to delta
(see picture 3);
2. change the setting of the thermal relay,
referring to the absorption values indicated
in the motor nameplate. If necessary,
replace the thermal relay with another one
of suitable scale.
This operation is not possible on motors
above 3 kW.
For more information, please contact the
Ecoflam staff.

Ionization current measurement
With the burner switched off, connect a DC
microammeter. When the burner is running,
and is properly adjusted, the value read must
be steady and never be smaller than 3 µA.
min. 3 μA
Position of electrodes
Setting the ionisation probe and
ignition electrode: see diagram
Always check the position of the
electrodes after service or substitution
or assembly of LPG kit as wrong position
might cause ignition problem.
Checks before commissioning
The following must be checked before
initial commissioning:
• That the burner is assembled in
accordance with the instructions given
here.
• That the burner is pre-set in accordance
with the values in the adjustment table.
• Setting the combustion components.
• The heat generator must be ready for
operation, and the operating regulations
for the heat generator must be observed.
• All electrical connections must be correct.
• The heat generator and heating system
must be filled with water and the
circulating pumps must be in operation.
• The thermostats, pressure regulator, low
water detectors and any other safety or
limiting devices that might be fitted must
be connected and operational.
• The exhaust gas duct must be
unobstructed and the secondary air
system, if available, must be operational.
• An adequate supply of fresh air must be
guaranteed.
• The heat request must be available.
• Sufficient gas pressure must be
available.
3
• The fuel supply lines must be assembled
correctly, checked for leaks and bled.
• A standard-compliant measuring point
must be available, the exhaust gas duct up
to the measuring point must be free of
leaks to prevent anomalies in the
measurement results.
