Riello G20 Installation, Use And Maintenance Instructions page 26

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.
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
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 verify-
ing:
– Smoke temperature at the chimney;
– Content of CO (%);
2
– Content of CO (ppm);
– Smoke value according to opacity smokes index according to
Bacharach scale.
