9.1 Gas valve setting
— Check that the inlet pressure is correct for
G20 gas;
Move the Summer/Winter Selector to Chimney
Sweep
position for at least 3 seconds, then let
the selector return to the Summer position. The
green led fl ashes rapidly and the burner ignites at
maximum rate for a defi ned period of time to allow
all of the checks to be made. The produced heat
is carried off by the heating system;
Wait for at least 10 seconds and check that the
pressure corresponds to the highest value indi-
cated in the “Power Pressure” table of the specifi c
model. If it is necessary to correct the pressure,
use the following procedure:
• make sure that the modulation coil is
energised;
• remove protection cap “C”. Take off the
silicon tube from the “VENT” on the gas
valve (item 3 in the fi gure);
• adjust maximum pressure by turning
knob “B”, with a 10 mm. spanner. Clock-
wise to increase, counterclock wise to
decrease;
• remove electrical connector on modulation coil;
• keeping knob “B” locked, adjust minimum pressure unscrewing screw “A” very
slowly, using a 4 mm screwdriver;
• refi t electrical connector on the modulator and check settings;
• turn off the burner by turning the Summer/Winter selector to the central position.
The green led fl ashes slowly.
• Refi t the silicon tube in the “VENT” on the gas valve (item 3 in the fi gure). ATTEN-
TION: after this operation, the value indicated by pressure gauge could decrease due
to pressure compensation. This is normal and does not require any adjustment.
Important: lock the adjustment device after any setting operation.
