Maintenance
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.
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 its accompanying instructions in
order to maintain all the original combustion characteristics in-
tact, especially the flue gas temperature and combustion cham-
ber pressure.
Combustion
Check there are no occlusions or obstructions in the fuel supply
or return lines, in the air suction areas, and in the combustion
product waste pipe.
Carry out an analysis of the combustion flue gases.
Significant differences with respect to the previous
measurements indicate the points where most care should be
exercised during maintenance.
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 combus-
tion 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
9.2.3
Safety components
The safety components must be replaced at the end of their life
cycle indicated in Tab. H.

WARNING
In case of use with gas oil containing up to 10%
Bio blend, it will be essential to use flexible oil
lines suitable for bio fuel use.
Please contact Riello for further information.
