CO It is advisable to not exceed 10% of CO
2
to avoid the risk that small changes of the adjustments due, for
instance, at draught variation, may cause combustion with
insufficient air and consequently formation of CO.
CO Not exceeding 100 mg/kWh (93 ppm).
IONIZATION CURRENT
The minimum current necessary for the
control box operation is 3 µA.
The burner normally supplies a higher cur-
rent value, so that no check is needed.
However, if you want to measure the ioni-
zation current, you
connector fitted to the red wire and insert a
