Combustion Adjustment - Riello GS5 Installation, Use And Maintenance Instructions

COMBUSTION ADJUSTMENT

In conformity with Efficiency Directive 92/42/EEC, the application of the burner on the boiler,
adjustment and testing must be carried out by observing the instruction manual of the boiler,
including verification of the CO and CO
the average temperature of the water in the boiler. It is advisable to set the burner according to
the type of gas used and following the indications of the table:

IMPORTANT
Do not turn the starting electrode but leave it as shown in the drawing; if the starting electrode is put
near the ionization probe, the amplifier of the control box might be damaged.

IONISATION CURRENT
The minimum current necessary for the
control box operation is 5 µA.
The burner normally supplies a higher cur-
rent value, so that no check is needed.
Should you want to measure the ionisation
current anyway, you must open the con-
nector (CN1) (see wiring diagram page 5) inserted in the red wire and insert a microammeter.
