Safety Components - Riello 40 FS5 Installation, Use And Maintenance Instructions

Pressure switches
Check that the air pressure switch and the gas pressure switch
are set correctly.
Gas leaks
Make sure that there are no gas leaks on the pipe between the
gas meter and the burner.
Gas filter
Change the gas filter when it is dirty.
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 measure-
ments indicate the points where most care should be exercised
during maintenance.
If the combustion values measured before starting maintenance
do not comply with applicable legislation or do not indicate effi-
cient combustion, consult the Tab. N on page 31 or contact our
Technical Support Service to implement the necessary adjust-
ments.
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:
– Percentage of CO (%);
2
– CO content (ppm)
– NOx content (ppm)
– Ionisation current (µA)
– Smoke temperature at the flue
