Notes on safety for the maintenance

The periodic maintenance is essential for the good operation,
safety, yield and duration of the burner.
It allows you to reduce consumption and polluting emissions and
to keep the product in a reliable state over time.
The maintenance interventions and the calibration
of the burner must only be carried out by qualified,
authorised personnel, in accordance with the con-
DANGER tents of this manual and in compliance with the
standards and regulations of current laws.
Before carrying out any maintenance, cleaning or checking oper-
ations:

Maintenance programme

9.2.1

Maintenance frequency

The gas combustion system should be checked at
least once a year by a representative of the man-
ufacturer or another specialised technician.
9.2.2

Checking and cleaning

The operator must use the required equipment
during maintenance.
Combustion head
Open the burner and make sure that all components of the com-
bustion head are in good condition, not deformed by the high
temperatures, free of impurities from the surroundings and cor-
rectly positioned.
Clean the combustion head in the fuel exit area, on the diffuser
disc.
Burner
Check for excess wear or loose screws and clean the outside of
the burner.
Fan
Check to make sure that no dust has accumulated inside the fan
or on its blades, as this condition will cause a reduction in the air
flow rate and provoke polluting combustion.
Photoresistance
Clean the photoresistance.
Electrodes
Check the correct position of electrodes.
Boiler
Clean the boiler as indicated in its accompanying instructions in
order to maintain all the original combustion characteristics in-
Maintenance
Disconnect the electrical supply from the burner
by means of the main system switch.
DANGER
Turn off the fuel interception tap.
DANGER
Wait for the components in contact with heat
sources to cool down completely.
Nozzles
It is advisable to replace nozzles every year during regular main-
tenance operations.
Do not clean the nozzle openings; do not even open them.
Filters
Check the filtering baskets on line and at nozzle present in the
system. Clean or replace if necessary.
If rust or other impurities are observed inside the pump, use a
separate pump to lift any water and other impurities that may
have deposited on the bottom of the tank.
Pump
Please check that the supply line and filters are clear. The use of
a pump vacuum gauge will assist in this. This measure permits
the cause of the anomaly to be traced to either the suction line or
the pump.
If the problem lies in the suction line, check to make sure that the
filter is clean and that air is not entering the piping.
Hoses
 Check periodically the flexible pipes conditions. They have
to be replaced at least every 2 years.
 In case of use of gas oil and bio fuel blends, it is strongly rec-
ommended to inspect even more frequently the hoses and
replace them where contamination has occurred.
 Check to make sure that the hoses are still in good condi-
tion.
In case of use with gas oil containing up to 30%
Bio blend, it will be essential to use flexible oil
lines suitable for bio fuel use.
WARNING Please contact Riello for further information.
Fuel tank
If water or contamination is present within the fuel tank, it is es-
sential that this is removed before the equipment is to be used.
This is extremely important when gas oil containing Bio diesel is
in use. If in doubt about how to achieve this then please contact
the fuel or oil tank supplier.
tact, especially the flue gas temperature and combustion cham-
ber pressure.
