OPERATION
Pilot flame ignition
Depress the button and ignite the pilot flame, fig. 1
keeping the button fully depressed for a few seconds
(fig.1). In controls with enabling for electrical
ignition, the pilot can be ignited automatically by
depressing the button . Release the knob and
check that the pilot flame stays lit. If it goes out,
repeat the ignition operation.
Main burner ignition
Depress the transverse button (fig.2) (manual
versions).
The gas passage to the main burner is opened by fig. 2
powering the automatic solenoid valve.
The valve with step ignition device reaches the
maximum flow after about 10 seconds.
Pilot flame ignition
Fully depress the knob (fig.1) to keep the main
burner closed and the pilot flame lit.
Shutdown
Fully depress the knob (fig.3).
fig. 3
CAUTION: the restart interlock device prevents igni-
tion of the appliance until the flame failure device has
stopped gas flow. At the end of this period (after clo-
sing the magnet unit) it is possible to carry out the
re-ignition operation.
INSTALLATION
Main gas connection
The connection is made using gas pipes with Rp 1/2 ISO 7 (or Rp 3/4) threading. Torque:
25 Nm. If, alternatively, flanges (available on request) are used, first screw the pipes onto
the flanges and then the flanges to the control. Recommended torque for the flange
fixing screws: 3 Nm.
Connection to the pilot burner
Pipes with a 4 mm, 6 mm or 1/4 diameter can be used. Use a nut and olive of appropriate
dimensions. Tighten to 7 Nm torque.
Electrical connections
All the electrical connections should be made in compliance with the provisions of the electrical
standards in force. Check that the voltage and frequency of the coils, indicated on the control,
are correct. Check that all the connections, in particular the earth, are carried out to industry
standards.
The 24Vac versions must be powered by an isolating transformer (with very low safety voltage).
Carry out the connections in accordance with the rules for the appliance.
To access the supply and earth terminals, unscrew the screw and remove the cover. To
access the electric ignition enabling terminals “W” (where applicable), unscrew the screw “M”
and remove the enabling device. The limit thermostat “LS” should be inserted into the ther-
moelectric circuit.
CAUTION: after making the connections, check gas tightness and electrical insulation.

SETTINGS AND ADJUSTMENTS
Measurement of the inlet and outlet
pressure
The inlet and outlet pressures of the gas can
be measured by unscrewing the provided test
point sealing screws.
Replace screws with 2.5 Nm torque.
Gas flow-rate adjustment to the pilot
Adjustment screw (PILOT ADJ.).
Screw in the screw to reduce the flow, or
unscrew it to increase flow.
Outlet pressure adjustment
Adjustment screw (REG. ADJ.).
Remove the protective cap, screw in the
adjustment screw (REG. ADJ.) to increase the
outlet pressure, or unscrew it to decrease flow.
Adjustment of the step ignition minimum
flow with…
