C4X Intake and exhaust in common and separate flues , but undergoing similar wind conditions
C8X Exhaust in single or common flue and wall intake
B3X Intake from installation room by means of concentric duct (that encloses the exhaust) and exhaust in com-

IMPORTANT - THE ROOM MUST BE PROVIDED WITH APPROPRIATE VENTILATION
If the boiler is to be connected FL 24 MCS to a collective flue or a single flue with natural
draught, the flue or chimney must be expressly designed by professionally qualified tech-
nical personnel in conformity with the current regulations and be suitable for sealed
chamber units equipped with fan.

4. SERVICE AND MAINTENANCE

4.1 Adjustments
Gas conversion
eq
The unit can work on natural gas or LPG and is factory-set for use with one of these two
gases, as clearly shown on the packing and data plate. Whenever a different gas to that
for which the unit is arranged has to be used, the special conversion kit will be required,
Horizontal
proceeding as follows:
1.0
1. Disconnect the power supply ahead of the boiler and close the gas cock;
2.0
2. Replace the nozzles at the main burner and pilot burner, fitting the nozzles indicated
in the technical data table in cap. 5, depending on the type of gas used
4.0
3. Connect the power supply ahead of the boiler and open the gas cock;
2.9
4. Modify the parameter for the type of gas:
2.9
• put the boiler in standby mode
3.0
• press the DHW buttons details 1 and 2 - fig. 1 for 10 seconds: the display shows
"b01" flashing.
2.5
• press the DHW buttons details 1 and 2 - fig. 1) to set parameter 00 (for opera-
2.5
tion with natural gas) or 01 (for operation with LPG).
0.2
• press the DHW buttons details 1 and 2 - fig. 1 for 10 seconds.
• the boiler will return to standby mode
3.0
7.0
5. Adjust the minimum and maximum pressures at the burner (ref. relevant para-
graph), setting the values given in the technical data table for the type of gas used
-
6. Apply the sticker, contained in the conversion kit, near the data plate as proof of the
5.0
conversion.

TEST mode. The boiler lights at the maximum heating power set as described in the fol-
lowing section.

Press the heating buttons (details 3 and 4 - fig. 1) to increase or decrease the power
(Min.=0%, Max.=100%).
By pressing the DHW "-" button (detail 1 - fig. 1), boiler output is immediately adjusted
to min. (0%). By pressing the DHW "+" button (detail 2 - fig. 1), boiler output is immedi-
ately adjusted to max. (100%).
If the TEST mode is activated and enough hot water is drawn to activate the DHW mode,
the boiler remains in TEST mode but the 3-way valve goes to DHW.
To deactivate the TEST mode, press the heating buttons (details 3 and 4 - fig. 1) together
for 5 seconds.
The TEST mode is automatically deactivated in any case after 15 minutes or on stopping
of hot water drawing (if enough hot water has been drawn to activate the DHW mode).
Pressure adjustment at the burner
Since this unit has flame modulation, there are two fixed pressure settings: 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" downstream of the
gas valve.
• Activate the TEST mode (see cap. 4.1).
• Press the Eco/Comfort button for 2 seconds to access the gas valve Calibration
mode.
• The card goes to the setting "q02"; displaying the actually saved value, by pressing
the DHW buttons .
• If the pressure gauge reading is different from the nominal maximum pressure, pro-
ceed by increases/decreases of 1 or 2 units of parameter "q02" by pressing the
DHW buttons : the value is stored after each modification; wait 10 seconds for the
pressure to stabilise.
• Press the heating button "-" (ref. 3 - fig. 1).
• The card goes to the setting "q01"; displaying the actually saved value, by pressing
the DHW buttons .
• If the pressure gauge reading is different from the nominal minimum pressure, pro-
ceed by increases/decreases of 1 or 2 units of parameter "q01" by pressing the
DHW buttons : the value is stored after each modification; wait 10 seconds for the
pressure to stabilise.
• Recheck both adjustments by pressing the heating buttons and adjust them if nec-
essary by repeating the above procedure.
• Press the Eco/Comfort button for 2 seconds to return to the TEST mode.
• Deactivate the TEST mode (see cap. 4.1).
• Disconnect the pressure gauge.
