9 Maintenance & Service
9.1 Notes on safety for the maintenance
Periodic maintenance is essential for the good operation,
safety, yield and duration of the burner.
It allows you to reduce consumption and polluting emis-
sions and to keep the product in a reliable state over time.
Before carrying out any maintenance, cleaning or check-
ing operations:
The maintenance interventions and the calibra-
tion of the burner must only be carried out by
qualied, authorised personnel, in accordance
with the contents of this manual and in com-
pliance with the standards and regulations of
current laws.
Disconnect the electricity supply from the burn-
er by means of the main switch of the system;
Isolate the fuel supply.

9.2 Maintenance programme
The combustion system should be checked ;
- at least once a year if Kerosene is being used by
a representative of the manufacturer or another
specialised technician.
- at least every 6 months if Gas Oil is being used
by a representative of the manufacturer or
another specialised technician.
Combustion head
Open the burner and make sure that all components of
the combustion head are in good condition, not deformed
by the high temperatures, free of impurities from the sur-
roundings and correctly positioned.
Clean the combustion head in the fuel exit area, on the
diuser disc.
Burner
Check for excess wear or loose screws and clean the out-
side 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 reduc-
tion in the air ow rate and provoke polluting combustion.
Photocell
Clean the photocell
Electrodes
Check the correct position of electrodes
Nozzles
It is advisable to replace nozzles every year or 6 months
depending on what fuel is being used. (see 9.2.1)
Do not attempt to clean the nozzle
Filters
Check the lter elements in-line and at the nozzle. Clean or
replace if necessary. If rust or other impurities are observed
inside the pump, use a separate pump to li any water and
other impurities that may have deposited on the bottom of
the tank.
Pump
Please check that the supply line and lters are clear. The
use of a pump vacuum gauge will assist in this. This meas-
ure 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 lter is clean and that air is not entering the piping.
9.2.2 Checking & cleaning
Flexible Hoses
• Check the condition of the exible pipes
periodically. They have to be replaced at least
every 2 years.
• In case of use of gas oil and biofuel blends, it is
strongly recommended 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 condition
The hose(s) supplied with this burner are suitable
for use with Kerosene, Gas oil and Biofuel blends of
FAME up to 100%
In case of use of a dierent Biofuel then please con-
tact EOGB for further information (a fuel specica-
tion may be requested)
Fuel tank
If water or contamination is present within the fuel tank, it
is essential that this is removed before the equipment is to
be used. This is extremely important when gas oil containing
Biodiesel is in use. If in doubt about how to achieve this then
please contact the fuel or oil tank supplier.
Boiler
Clean the boiler as indicated in the appliance accompany-
ing instructions in order to keep all the original combustion
characteristics intact, especially the ue gas temperature
and combustion chamber pressure.
Combustion
In case the combustion values found at the beginning of
the intervention do not respect the standards in force or in
any case, do not correspond to a proper combustion, con-
tact the Technical Assistant and allow them to carry out the
necessary adjustments.
Allow the burner to work for 10 minutes. and then check the
combustion readings with the parameters indicated within
the appliance instruction manual.
Then carry out a combustion check verifying:
• Flue gas temperature at the chimney;
• Content of CO2 (%);
• Content of CO (ppm);
• Smoke value according to opacity smokes index
according to Bacharach scale.
