Burner pressure adjustment
Since this unit has flame modulation, there are two fixed pressure values: the minimum and maximum, which must be
those given in the technical data table according to the type of gas.
• Connect a suitable pressure gauge to the pressure point "B" located downstream of the gas valve.
• Disconnect the pressure compensation tube "H".
• Remove the protection cap "D".
• Operate the boiler in TEST mode, turning the selector to TEST.
• Adjust the maximum pressure with the screw "G", turning it clockwise to increase and anticlockwise to decrease the
pressure.
• Disconnect one of the two faston connectors from the modureg "C" on the gas valve.
• Adjust the minimum pressure with the screw "E", turning it clockwise to decrease and anticlockwise to increase the
pressure.
• Refit the faston connector removed from the modureg on the gas valve.
• Make sure the maximum pressure has not changed.
• Reconnect the pressure compensation tube "H".
• Refit the protection cap "D".
• To end TEST mode, turn the selector to a different position from TEST or wait 15 minutes.
