SETTINGS AND ADJUSTMENTS
All adjustments must be made on the basis of the specific characteristics of the appliance.
Check inlet and outlet pressure using the pressure test points and . After testing, carefully seal test points with
the provided screws. Recommended torque: 2.5 Nm.
Adjusting maximum and minimum outlet flow
These adjustments must be made when the thermostatic bulb is cold.
Maximum flow (versions without pressure regulator) - fig. A.
Turn the knob to position 7. Screw in the adjustment screw fully, turn the adjustment screw anticlockwise to
increase the gas flow.
CAUTION:
After screwing in fully, do not unscrew the adjustment screw more than two turns.
Overriding the flow adjustment function
Screw in the adjustment screw fully, unscrew it two complete turns and seal it. Alternatively, the gas flow
adjustment function may be excluded by substituting the adjustment screw with the plug code 0.972.057.
In this case the plug must be fixed firmly.
Maximum flow (versions with pressure regulators) - fig. A'
Turn the knob to position 7. Screw the adjustment screw clockwise to increase gas flow.
Overriding pressure regulator
Rotate the adjustment screw completely in a clockwise direction.
Minimum flow
Starting from position 7, slowly turn the knob clockwise to the minimum flow position (just before the main burner
shut-off). Turn screw anticlockwise to increase the flow. It is possible to use screws with calibrated holes (available
on request) to replace the maximum and minimum flow adjustment screws. In this case, it is necessary to tighten these
screws to a torque of 7 Nm.
Adjustment of gas flow to the pilot burner
Turn screw clockwise to reduce the flow.
Overriding the pilot flow adjustment function
Screw in adjustment screw fully and then unscrew it two complete turns.
Seal the adjustment.
Changing the gas family or group
Check that the appliance is suitable for operation with the gas family or group desired.
Following the instructions given above, adjust the outlet pressure to the values given in the appliance's instruction
booklet. With Family III gas: override the maximum flow adjustment or the pressure regulator according to the version.
Override the adjustment of the gas flow to the pilot burner.
IMPORTANT:
At the end of all setting and adjustment operations, check gas seals and the efficiency of the appliance.
It is particularly important to check that flame lift or light back to minimum and maximum outlet pressures are absolutely
impossible. After carrying out all adjustments, fit the provided seals and/or block the setting screws with paint.
