Maintenance
Nozzles
It is advisable to replace nozzles every year during regular main-
tenance operations.
Do not clean the nozzle openings.
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 light oil containing bio diesel is
in use. If in doubt about how to achieve this then please contact
the fuel or oil tank supplier.
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 As-
sistant in order to carry out the necessary adjustments.
Leave the burner working without interruptions for 10 min. and set
rightly all the components stated in this manual.
Then carry out a combustion check verifying:
– Smoke temperature at the flue;
– Percentage of CO
2
;
– CO content (ppm);
– Smoke value according to opacity smokes index according to
Bacharach scale.
