H1 = Running time counter
SB = Fault alarm
Note:
If, in the case of a Riello front-mounted burner, a running
time counter (H1) is connected by means of a cable
longer than 3 m, a 47 nF capacitor must be fitted bet-
ween B4 and earth to prevent EMI.
The same applies to the installation of a fault alarm (SB);
in this case a 100 nF capacitor must be fitted between S3
and earth, if the cable length exceeds 3 m.
