Adjusting burner pressure
Since this unit has flame modulation, there are two fixed pressure settings: the minimum and maximum,
which must be as stated in the technical data chart according to the type of gas.
• Connect a suitable pressure gauge to pressure point “ B ” downstream from the gas valve.,having loo-
sened it first
• Disconnect the pressure compensation tube “ H ”.
• Take off the protective cap “ D ”.
• Run the boiler in TEST mode (press the multi-function button 3 times in 3 seconds):
- TEST mode on: turn the heating knob (ref. 1 - fig 1) onto maximum.
• Adjust the maximum pressure with the screw “
G ”, clockwise to increase it and anticlockwise to decrease
it.
• Disconnect one of the two electrical connectors from the modureg “ C ” on the gas valve.
• Adjust the minimum pressure with the screw “ E ”, clockwise to decrease it and anticlockwise to increase it.
• Reconnect the electrical connector disconnected from the modureg on the gas valve.
• Check that the maximum pressure has not changed.
• Reconnect the pressure compensation tube “
H ”.
• Put the protective cap “ D ” back on.
• To end TEST mode, repeat the sequence for turning it on or wait 15 minutes
• Shut down the boiler
• Remove the pressure gauge
• Re-seal test point ‘B’
• Re-light the boiler and check for gas leaks using a suitable “Leak detection fluid”

Having disturbed test point ‘B’ when
checking or adjusting the gas pressures, it
is considered mandatory to check for gas
leaks using a suitable leak detection fluid
or sniffer.at that connection
