Combustion head calibration
Before securing the burner to the boiler check for model RS 130/E,
whether the maximum delivery of the burner at high fire operation
is contained in area A or in area B of the firing rate. See Fig. 3.
If it is in area A then no operation is required.
If, on the other hand, it is in area B:
unscrew the screws 1)(Fig. 12) and disassemble the blast
tube 2);
move the fixing of the rod 3)(Fig. 12) from position
C
to posi-
tion
D
, thereby causing the shutter 4) to retract;
now refit the blast tube 2)(Fig. 12) and the screws 1).
Once this operation has been carried out (if it was required), se-
cure the flange 11)(Fig. 11) to the boiler plate, inserting the gas-
ket 8).
Use the 4 screws, also supplied with the unit, after first protect-
ing the thread with an anti-locking product.
The seal between burner and boiler must be airtight.

Electrode and ignition pilot adjustment
To verify the correct position of the electrode (Fig. 13), you need
to extract the internal part of the head 2)(Fig. 14).
Place the electrode and the ignition pilot as shown in Fig. 13.
The ignition pilot works correctly at pressures ranging from 5 -
12” WC.
Proceed as follows:
loosen the 4 screws 3) (Fig. 11) and remove the hood 1);
remove the screws 2) from the two guides 5), (only for long
blast tube version);
install the extensions 15) and re-screw the screws 2), (only
for long blast tube version);
remove the two screws 4);
pull back the burner on the guides 5) of about 4”;
disconnect the electrode lead, then pull back the burner to the
screws 2) (Fig. 11);
remove the screw 1) (Fig. 14) and extract the inner part 2) of
the head;
check the correct position of ignition electrode, as shown in
Fig. 13.
Re-install the inner part of the head with reverse proce-
dure.
