• Setthemaximumpressuretothedesiredvaluebyrotatingthepres-
sure regulator adjustment screw (4) with a 10 mm spanner. Turning
clockwise increases and anti-clockwise reduces the pressure.
• Settheminimumpressuretothedesiredvaluebyrotatingtheredmi-
nimum pressure adjustment screw (3). Turning clockwise increases
and anti-clockwise reduces the pressure.
• Replaceyellowpressureregulatorcap(2)andthemodulationcab-
les.
NOTE: For I3+ category adjusted appliances, where adjustment of the
maximum pressure is not allowed and gas supply pressures do not ex-
ceed 29 mbar for G30 (butane) and 37 mbar for G31 (propane), set the
maximum pressure regulator adjustment screw to its maximum position,
then set the minimum pressure regulator adjustment screw as above.
ATTENTION! To disable unauthorized persons’ interference, the yellow
cap on the gas valve should be painted with a red paint to seal it.
