IMPORTANT - THE ROOM MUST BE PROVIDED WITH APPROPRIATE VENTILATION
If the boiler is to be connected DOMIproject F 24 D to a collective flue or a single flue
with natural draught, the flue or chimney must be expressly designed by professionally
qualified technical 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
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 gas dif-
ferent from that for which the unit is arranged has to be used, the special 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 cap. 5, according to the type of gas used
2. Modify the parameter for the type of gas:
• put the boiler in standby mode
• press the DHW buttons (details 1 and 2 - fig. 1) for 10 seconds: the display
shows "b01" blinking.
eq
• Press the DHW buttons (details 1 and 2 - fig. 1) to set parameter 00 (for natural
gas operation) or 01 (for LPG operation).
Horizontal • press the DHW buttons (details 1 and 2 - fig. 1) for 10 seconds.
• the boiler will return to standby mode
1.0
2.0 3. 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

4. Apply the sticker contained in the conversion kit, near the dataplate as proof of the
2.9
conversion.

7.0 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.
