4. SERVICE AND MAINTENANCE
All adjustment, conversion, startup and maintenance operations described below must
only be carried out by Qualified Personnel (meeting the professional technical require-
ments prescribed by current regulations) such as those of the Local After-Sales Techni-
cal Service.
FERROLI declines any liability for damage and/or injury caused by unqualified and un-
authorised persons tampering with the unit.
4.1 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, fitting the nozzles specified in the technical
data table in sec. 5.2, according to the type of gas used
2. Modify the parameter for the type of gas:
• put the boiler in standby mode
• Press the reset button (detail 8 - fig. 1) for 10 seconds: the display shows "TS"
flashing
• press the reset button (detail 8 - fig. 1): the display shows "P01“.
• Press the DHW buttons (details 1 and 2 - fig. 1) to set parameter
00 (for natural gas operation) or 01 (for LPG operation).
• Press the reset button (detail 8 - fig. 1) for 10 seconds.
• the boiler will return to standby mode
3. Adjust the minimum and maximum pressures at the burner (refer to relevant sec-
tion), setting the values given in the technical data table 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 fig. 13 and 4 - ) at the same time for 5
seconds to activate the TEST mode. The boiler lights at the maximum heating power
set as described in the following section.
The heating symbol (detail 24 - fig. 1) and DHW symbol (detail 12 - fig. 1) flash on the
display; the heating power and lighting power will be displayed alongside.
fig. 26 - TEST mode (heating power = 100%)
To deactivate the TEST mode, repeat the activation sequence.
The TEST mode is automatically disabled in any case after 15 minutes.
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 “N”.
• Remove the protection cap “D”.
• Operate the boiler in TEST mode.
• Adjust the maximum pressure by turning the screw “G” clockwise to increase the
pressure and anticlockwise to decrease it.
• Disconnect one of the two fastons "C" from the modureg "F" on the gas valve.
• Adjust the minimum pressure by turning the screw "E" clockwise to increase the
pressure and anticlockwise to decrease it.
• Turn the burner on and off, checking that the minimum pressure remains stable.
• Reconnect the faston "C" detached from the modureg "F" on the gas valve
• Check that the maximum pressure has not changed
• Reconnect the pressure compensation tube “N”.
• 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-
ment screw with paint or a specific seal.

Heating power adjustment
To adjust the heating power, set the boiler on TEST operation (see sec. 4.1). Press the
heating buttons (part 3 and 4 - fig. 1) to increase or decrease the power
(minimum = 00 - Maximum = 100). Press the RESET button within 5 seconds
and the maximum power will remain as has just been set. Exit TEST operation (see
sec. 4.1).
Ignition power adjustment
To adjust the ignition power, set the boiler on TEST operation (see sec. 4.1). Press the
tap water buttons (part 1 and 2 - fig. 1) to increase or decrease the power
(minimum = 00 - Maximum = 60). Press the button within 5 seconds and the
ignition power will remain as has just been set. Exit TEST operation (see sec. 4.1).
4.2 System start-up
B
Checks to be made at first ignition, and after all maintenance operations that
involved disconnecting from the systems or an intervention on safety devices
or parts of the boiler:
Before lighting the boiler
• Open any on-off valves between the boiler and the systems.
• Check the tightness of the gas system, proceeding with caution and using a soap
and water solution to detect any leaks in connections.
• Check the correct preloading of the expansion tank (ref. sec. 5.2)
• Fill the water system and make sure that all air contained in the boiler and the sys-
tem has been vented by opening the air vent valve on the boiler and any vent valves
on the system.
• Make sure there are no water leaks in the system, hot water circuits, connections or
boiler.
• Check the correct connection of the electric system and the functioning of the earth
system. l
• Check that the gas pressure value for heating is as required.
• Make sure there are no flammable liquids or materials in the immediate vicinity of
the boiler
