3. SERVICE AND MAINTENANCE

All adjustment, conversion, commissioning and maintenance operations described be-
low must only be carried out by Qualified Personnel (meeting the professional technical
requirements prescribed by the current regulations) such as those of the Local After-
Sales Technical Service.
LAMBORGHINI declines any liability for damage and/or injury caused by unqualified and
unauthorised persons tampering with the unit.

3.1 Adjustments

Gas conversion
The unit can operate on Natural Gas or LPG and is factory-set for use with one of these
two gases, as clearly shown on the packing and on the dataplate. Whenever a different
gas to that for which the unit is arranged has to be used, a conversion kit will be required,
proceeding as follows:
1. Replace the nozzles at the main burner, inserting the nozzles specified in the tech-
nical data table in sec. 4.3, according to the type of gas used
2. Modify the parameter for the type of gas:
• switch the boiler to standby mode
• press the RESET button R (detail 6 - fig. 1) for 10 seconds: the display shows
"TS" flashing
• press the RESET button R (detail 6 - fig. 1): the display shows "P01".
• Press the DHW buttons fig. 1 (details 1 and 2 - ) to set parameter 00 (for oper-
ation with natural gas) or 01 (for operation with LPG).
• Press the RESET button R (detail 6 - fig. 1) for 10 seconds.
• the boiler will return to standby mode
3. Adjust the burner minimum and maximum pressures (ref. relevant section), setting
the values given in the technical data chart for the type of gas used
4. Apply the sticker contained in the conversion kit, near the dataplate as proof of the
conversion.
TEST mode activation
Press the heating buttons (details 3 and 4 - fig. 1) at the same time for 5 seconds to
activate TEST mode. The boiler lights at the maximum heating power set as described
in the following section.
The heating symbol (detail 13 - fig. 1) and DHW symbol (detail 9 - fig. 1) flash on the dis-
play; the heating power will be displayed alongside.
fig. 17 - TEST mode (heating power = 100%)
To deactivate TEST mode, repeat the activation sequence.
TEST mode is automatically disabled in any case after 15 minutes.
Pressure adjustment at burner
Since this unit has flame modulation, there are two fixed pressure values: the minimum
and maximum, which must be as specified 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.
• Remove the protection cap "D".
• Operate the boiler in TEST mode by pressing the heating buttons (details 3 and 4 -
fig. 1) at the same time for 5 seconds.
• Adjust the heating power to 100.
• Adjust the maximum pressure with the screw "G", turning it clockwise to increase
and anticlockwise to decrease the pressure.
• Detach one of the two faston connectors "C" from the modureg on the gas valve.
• Adjust the minimum pressure with the screw "E", turning it clockwise to decrease
and anticlockwise to increase the pressure.
• Reconnect the faston connector removed from the modureg on the gas valve.
• Check that the maximum pressure has not changed.
• Refit the protection cap "D".
• To end 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 (details 3 and 4 - fig. 1) 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).
