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
Delivery pressure must correspond with the table on Tab. F to
page 19. 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 suc-
tion 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
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 condi-
tion.
The hoses supplied with this burner set for
Kerosene use are not suitable for use with Gas oil
containing a Bio blend.
WARNING
Please refer to the spare part list for the specific
hoses suitable for bio fuel use.
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.
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.
Boiler
Clean the boiler as indicated in the appliance accompanying in-
structions in order to maintain all the original combustion charac-
teristics intact, especially the flue gas temperature and
combustion chamber pressure.
Combustion
In case the combustion values found at the beginning of the inter-
vention do not respect the standards in force or, in any case, do
not correspond to a proper combustion, contact the Technical
Assistant and have him carry out the necessary adjustments.
Allow the burner to work for 10 min. and then check the
combustion readings with the parameters indicated within the
appliance instruction manual. Then carry out a combustion
check verifying:
– Smoke temperature at the chimney;
– Content of CO
(%);
2
– Content of CO (ppm);
– Smoke value according to opacity smokes index according to
Bacharach scale.
