Adjustment of pressure at burner
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 pressure point "B" downstream of the gas
valve
• Disconnect the pressure compensation tube "H" and remove the protection cap
"D", undoing screw "A".
• Operate the boiler in TEST mode.
• Set the heating power to 100.
• Adjust the max. pressure with screw "G", clockwise to increase it and anticlockwise
to decrease it
• Disconnect one of the two fastons from modureg "C" on the gas valve.
• Adjust the min. pressure with screw "E", clockwise to decrease it and anticlockwise
to increase it.
• Reconnect the faston detached from the modureg on the gas valve.
• Check that the maximum pressure has not changed.
• Reconnect the pressure compensation tube "H".
• Refit the protection cap "D".
• To end the TEST mode, repeat the activation sequence or wait 15 minutes.
After checking or adjusting the pressure, make sure to seal the adjust-
A
ment screw with paint or a specific seal.

Heating power adjustment
To adjust the heating power, switch the boiler to TEST mode (see sec. 3.1). Press the
heating buttons fig. 1 (details 3 and 4 - ) to increase or decrease the power (min. = 00 -
max. = 100). Press the RESET button within 5 seconds and the max. power will remain
that just set. Exit TEST mode (see sec. 3.1).
Lighting power adjustment
To adjust the lighting power, switch the boiler to TEST mode (see sec. 3.1). Press the
DHW buttons (details 1 and 2 - fig. 1) to increase or decrease the power (min. = 00 - max.
= 60). Press the RESET button within 5 seconds and the lighting power will remain that
just set. Exit TEST mode (see sec. 3.1).
