Safety Components - Riello RLS 120/E FGR Installation, Use And Maintenance Instructions

Fan
Check to make sure that no dust has accumulated inside the fan
or on its impellers, as this condition will cause a reduction in the
air flow rate and provoke polluting combustion.
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.
Flame sensor
Clean the glass cover from any dust that may have accumulated.
To remove the sensor, pull it forcefully towards the outside; it is
only pushed in.
Measuring the flame signal
The burner is fitted with a sensor to check that a flame is present.
The display (Fig. 47) will display the intensity of the flame signal.

GAS OIL OPERATION
Pump
The depression must be less than 0.45 bar.
Unusual noise must not be evident during pump operation.
If the pressure is found to be unstable or if the pump runs noisily,
the flexible hose must be detached from the line filter and the fuel
must be sucked from a tank located near the burner.
This measure permits the cause of the anomaly to be traced to
either the suction piping or the pump.
If the problem lies in the suction line, check the filter is clean and
that air is not entering the piping.
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.
Nozzles
It is advisable to replace nozzles once a year during periodical
maintenance.
Do not clean the nozzle openings.
Hoses
Check that these are in good conditions.
Fuel tank
Approximately every 5 years, suck any water on the bottom of the
tank using a separate pump.

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-
sistance Centre in order to carry out the necessary adjustments.
