WARNING NOTES
4.Burners
is device should only be used in boilers for
applications that are connected to hot water boilers,
ovens or other similar equipment and are not
exposed to atmospheric agents (rain, dust, etc.).
Other forms of use are inadequate and, therefore, It
is dangerous.
e burner should be installed in the appropriate
locations according to the regulations in force and
in all cases where adequate ventilation is available to
ensure proper combustion.
Do not reduce or cover the ventilation opening of
the burner or the boiler room where the boiler is
installed and the burner air intake grill opening, as
hazardous oxide mixtures and explosive gas forms
may form.
Before connecting the burner, check the information
on the system feed (electrical, gas, motor, or other
fuel) related information on the label on the front.
Do not touch the hot parts of the burner. Usually in
the areas near to the ame and the fuel preheating
system components are hot during operation of the
device and remain hot for some time.
If the burner is no longer used, the following
operations must be carried out by authorized
technicians;
a)Disconnecting the power supply line from the
main switch, disconnecting the power supply,
b)Closing the fuel supply using the shuto valve and
removing the valve release lever,
c)Picking up parts of potentially hazardous parts,
5. Special Alerts
Check that the connection of the burner to the heat
generator is secure, as it will occur in the ame
combustion chamber. e following procedures are
required to be tested by authorized technicians at
least once a year and once before commissioning the
burner;
a) Adjustment of burner fuel level, adjustment of the
capacity of the heat generator.
b) Adjustment of the combustion air ow at least
to ensure combustion eiciency of the burner at
the minimum air ow rate declared by the current
regulations.
c) Check that NOx and unburned gases causing air
pollution do not exceed the permissible limit values
according to the current legislation.
d) To check that the safety devices and control
devices are working properly.
e) Checking the condition of the duct where the
combustion products are discharged.
f) Aer the setting operations have been carried out,
the mechanical safety locks of the adjusting devices
must be made,
g) To check that the burner operating and
maintenance manual is in the boiler room.
If the burner is continuously failing, do not try
to reset it more than twice. Call your nearest
authorized service agent to resolve the problem.
According to the regulations in force, the operation
and maintenance of the equipment should only be
carried out by authorized services.
6. Electrical Connection
e equipment is only electrically safe if properly
connected to the appropriate earthing line
according to current electrical safety legislation.
It is necessary to check that the necessary safety
requirements have been fulfilled. If you are in
doubt, have a certified electrician check the system.
Because the manufacturer is not responsible for
damage caused by poor grounding connection.
e suitability of the electrical circuits for
maximum loads of the equipment must
be checked by authorized services. Have the
certified electrician check that proper wiring is done
according to the maximum power drawn by the
burner as shown on the technical labels, especially
if the cable diameters are suicient for the power
drawn.
According to the current safety legislation, it is
necessary to use a polarity switch to connect the
main power supply.
e burner power supply must have neutral
grounding. If the ionization current is controlled
from an ungrounded neutral, a connection must be
made between the terminal 2 (neutral) and ground
