GAS TYPE (P. 1)
Modify the set value as follows:
- press ENTER to access the parameter modification function. When ENTER
is pressed, the previously set value starts flashing (Fig. H)
- turn the domestic hot water temperature selector to change the value (1 MTN
- 2 LPG)
- press ENTER to confirm the new value. The digits stop flashing.
BOILER POWER (P. 2)
To modify the boiler power:
- select parameter 02
- press the ENTER button to access the parameter value modification function.
As the ENTER button is pressed, the digits flash, highlighting the previously
set value
- turn the sanitary water temperature selector in order to adjust the value to the
desired number: 26 (25 kW) and 34 (35kW) for GREEN C.S.I.; 16 (16kW),
26 (25 kW) and 34 (35kW) for GREEN R.S.I.
- confirm the new value you have set by pressing ENTER. The digits stop
flashing.
It is absolutely forbidden to set different gas types and/or boiler powers
from those indicated on the registration plate.
The manufacturer refuses any responsibility if the 2 parameters are set at
different values compared to those indicated on the registration plate.
MAXIMUM VENTILATOR SPEED (P. HP)
- Select parameter HP
- Press the ENTER button, then modify the value of the parameter by turning
the sanitary water temperature selector. The maximum speed of the fan is
linked with the type of gas and the power of the boiler,
table 1
- Turn the sanitary water temperature selector in order to adjust the set value
- Confirm the new value you have set by pressing ENTER.
The value indicated on the display is expressed in revs min/100 (example 3600
= 36).
The value set during this operation automatically modifies the maximum value
of parameter 23.
MINIMUM VENTILATOR SPEED (P. LP)
- Select parameter LP
- Press the ENTER button, then modify the value of the parameter by turning
the sanitary water temperature selector. The minimum speed of the fan is
linked with the type of gas and the power of the boiler,
table 2
- Turn the sanitary water temperature selector in order to adjust the set value
- Confirm the new value you have set by pressing ENTER.
The value indicated on the display is expressed in revs min/100 (example 3600
= 36).
The value set during this operation automatically modifies the maximum value
of parameter 24.
VENTILATOR IGNITION SPEED (P. SP)
- Select parameter SP
- Press the ENTER button, then modify the value of the parameter by turning
the sanitary water temperature selector. The standard slow start value is
3700 revs/min
- Confirm the new value you have set by pressing ENTER.
MAXIMUM POWER ADJUSTMENT (P. HH) (Fig. 1.17)
- Turn the boiler OFF
- Select the parameter HH and wait for the boiler to come on
- Check that the maximum CO
2
reading on the analyser (see paragraph
“Checking combustion parameters”, page 23) corresponds with the values
indicated in
table 3
.
If the CO
2
proves to comply with the values in the table, proceed to adjust the
next parameter (LL - adjusting the minimum), if different modify the value by
turning the maximum power adjustment screw with a screwdriver (clockwise to
decrease) until you obtain a value contained in
table 3
.
MINIMUM POWER ADJUSTMENT (P. LL) (Fig. 1.17)
- Select the parameter LL (with the boiler still OFF) and wait for the boiler to
come on.
- Check that the minimum CO
2
reading on the analyser (see paragraph
“Checking combustion parameters”, page 23) corresponds with the values
indicated in
table 4
.
If the CO
2
proves to be different from the values in the table, proceed to adjust
the parameter by turning the maximum power adjustment screw after having
unscrewed the protective cap (clockwise to increase) until you obtain a value
contained in
table 4.
IGNITION SPEED (P. MM)
- Select parameter MM.
The boiler starts at the slow ignition speed.
- Turn the heating water selector to increase or decrease the fan speed.
MAXIMUM HEATING ADJUSTMENT POSSIBILITY (P. 23)
- Select parameter 23
- Press the ENTER button to access the parameter value modification function
- Turn the sanitary water selector to modify the maximum fan speed
- Confirm the value you have set by pressing ENTER.
MINIMUM HEATING ADJUSTMENT POSSIBILITY (P. 24)
- Select parameter 24
- Press the ENTER button to access the parameter value modification function
- Turn the sanitary water selector to modify the minimum fan speed
- Confirm the value you have set by pressing ENTER.
Exit the CALIBRATION & SERVICE function by pressing ESCAPE.
The boiler returns to the “- -” (OFF) status.
To reset, press the button.
- Disconnect the pressure gauge and tighten the pressure tap screw.
After adjusting the gas valve, seal it with sealing wax.
After making adjustments:
- return the temperature set with the ambient thermostat to the required position
- close the panel
- put back the shell.
19 - GAS CONVERSION
It is easy to convert from one gas family to another even after the boiler has
been installed. This operation must be performed by professionally qualified
staff. The boiler is designed to work with natural gas or LPG. The product plate
indicates which fuel it has been fitted out to use.
It is possible to convert the boiler from one kind of gas to the other using kits
which can be supplied on request:
- natural gas to LPG conversion kit
- LPG to natural gas conversion kit.
To disassemble, proceed as follows:
- disconnect the boiler from the power supply and close the gas tap
- remove the components to access to the internal parts of the boiler (Fig.
1.18-1.19)
- remove the gas ramp (
A
)
- remove the nozzle (
B
) contained inside the gas ramp and replace it with the
one contained in the kit
- remount the gas ramp
- remount components previously removed
- power the boiler and open the gas tap (with the boiler working, check there
are no leaks in the gas supply circuit).
